The answer from the person in Vienna was excellent.  Let me add:
 
Pheromone lures positioned on traps only work in fairly still air.  The 
molecules of the lure have to build up a bit to attract the male moths.  Any 
molecules making their way outdoors would be diluted by even a slight wind and 
not leave a "trail" sufficient for the males to follow.

CLASSIFICATION: UNCLASSIFIED

Good morning.  I work for the US Army at one of their museums and we use 
pheromone pest control traps, especially for carpet beetles.  One of my staff 
was at a US Army museums course two weeks ago and was told by two conservators 
that all pheromone traps must be removed from all Army museums as they lure 
bugs in from outside with the pheromone - like through doors and windows.  They 
stated that it attracts more insects in to the buildings and makes it more 
difficult to control pests (we have these pheromone traps as well as ground 
traps near doors and windows to catch anything coming in - no carpet beetles in 
the floor traps but we do get a couple in the pheromone traps).  I have never 
heard of this happening before and wanted to check to see anyone has heard of 
this or knew approximately how far one of the pheromone traps "odor" went out 
from the trap.  I just can't see that one of these small traps can lure insects 
through doors and walls like the two conservators stated.  Any information you 
could provide would be greatly appreciated.

Thank you.

The first step is to determine if the damage has been caused by drywood or 
subterranean termites.  If it is caused by subterranean termites, then just 
bagging the items will fairly quickly kill whatever worker termites remain in 
the object.  If it's drywood termites then bagging and freezing would be the 
easiest remedy.

Thank you so much for that note, Joel.  Admittedly, my main goal right now is  
attempting to ensure that we're left with something to preserve until I get the 
"go ahead" to have the items removed and the suitable expert brought in to 
safeguard this very valuable collection.

Key note . wooden items would need to have a moisture content less than 19% 
in order for bag/isolation to be faster and a total guaranteed success 
depending of the extent and species of the termites. In case other are thinking 
this may work for all situations. JTV

Hello,


Kindly permit me to intervene into this space to ask for safe, efficient, and 
cost-effective solutions for remedying severe termite infestations of artefacts 
and documentary heritage that are slated to become part of a special museum 
collection.  We have inherited a collection of artefacts and documents, many of 
which show clear signs of termite infestation or damage from said infestation 
and which are currently still being housed in a building suffering severe 
disrepair.  In an effort to curtail the spread of the infestation whilst the 
pieces are still in their unsuitable environment, I have taken to bagging 
(wrapping the wooden sculptures in plastic bags and sealing them with tape. I 
have also isolated documents in bags.  Removal from the premises is understood 
as a necessary step to ensure the rehabilitation of these items.  Also, 
freezing has been suggested as well as anoxia. Any advice you give will be 
greatly appreciated as this is very new territory for us.


Best regards

Elizabeth,


I think you can cross webbing/case making moths off the list for that first 
one.  On your moth, the head looks different, the body looks a little "thicker" 
and webbing moth larvae are white.


Not sure on that second one...

Hello all, 


I would be grateful if you could help me identify these moths. Both are the 
first of either type we have found. The moth in image 1 also appears to have 
larvae associated with it on the trap. The trap has only been in place since 
September 19.

Hello Everyone,


A mask recently came in with evidence of wood boring pests.  We will be 
freezing the mask.  The beetle pictured was found in the wrapping (it was found 
dead).  I am wondering, can anyone confirm if this is a Powderpost beetle vs a 
Furniture beetle?


In the end, does distinguishing between the 2 really matter? (treatment 
methods, severity of damage, one being considered "worse" than the other...)


Thanks!

In addition to Tony's comments, in the U.S. we commonly call these types of 
moths underwing moths because the second pair of wings is usually colorful and 
the top or first pair exhibit a camouflaged appearance.  Another common name 
for this group is sphinx moths.  As Tony stated, they are highly attracted to 
exterior lights at night.

It is definitely NOT webbing clothes moth silk.  Remember, it's the larvae of 
WCM's that spin the silken threads from their salivary glands.  With this being 
true, you'd see all sorts of damage and pelletized frass associated with the 
webbing.  There is no damage or frass on this piece of fabric.

Hi Megan 
This is a Monopis species - almost certainly M. crocicapitella, the Pale-backed 
Clothes Moth (though it is known in the US as the "Bird Nest Moth"). It is 
becoming a frequent pest in domestic and public buildings in Europe, or at 
least it is coming to our notice more frequently, especially as it is attracted 
to Tineola pheromone traps. Although the adults can be abundant, finding larvae 
is proving much more difficult.
Best wishes
Tony

Yup.  Drywood termite.  The frass will be the color of the wood in which they 
are feeding.  The workers make a "kick hole" out of which they discard the 
frass.  If you open up their galleries, there will be lots of pelletized frass 
in them.  The pellets look like old time, deflated footballs.

I’ll second ground beetle and echo William’s statement of “accidental” visitor 
and not necessary to dive too deep into in terms of nailing down a species. 
 
Dead ones in numbers can provide food for dermistids.   Eliminating them or 
preventing them from entering is still a good thing!

Hello Erika,
 
I’ll take a stab here. It appears to be a ground beetle of some 
kind. More knowledgeable subscribers can likely narrow it down further, there’s 
so many different species, but might not be necessary for your purposes. Likely 
an accidental visitor more so than a ‘museum pest’ as they tend to be 
invertebrate predators. If I’m correct about it being a ground beetle, as a 
defense they can secrete substances that could potential harm collections but 
likely less of a worry than someone accidently squishing a specimen with 
something. As long as you’re not seeing several specimens probably not to be an 
ongoing concern but I’d be interested in hearing what others have to say.

This little beetle was found in a case that contained a vellum scroll. I looked 
in my IPM books--but I have not been able to identify him. The color is a 
little off in the picture…in real life the beetle is a reddish-brown color. Any 
clues as to what this little guy may be would be much appreciated!

Interesting! Thank you. I do get a carpet beetle here and there but not very 
often. I have some dermestid traps as well, so I will also try placing those 
next to the sticky traps to see if I get any results. I don’t see damage on the 
artifacts but then it can be difficult to tell with history collections.

Hi Betsy

The "ant" is a rove beetle (Staphylinidae) - just an accidental intruder, and 
not a threat other than providing food for pests likeAnthrenus.

The crime scene is evidence of active Anthrenus infestation - these are typical 
remains with frass after a good feed. In the top of the picture, you can see 
some fine hairs which theAnthrenus larva has shed while making its escape.

It may be wise to replace the blunder traps more regularly - no point in 
leaving food around to keep theAnthrenus population going.

Best wishes

I have two questions - see attached images. One is a pest that resembles an ant 
and is about a quarter of an inch long – except it has different body parts 
than most ants, and no pincers like earwigs. The second is the crime scene 
sticky trap. I see this fairly often. Assuming these are spider eggs, is it the 
case that the spider gets stuck on the glue, which causes it to lay all its 
eggs, and then something comes along and eats the spider? Or is it frass?

Hello!

Sorry I didn’t get back to everyone yesterday, I ended up 
needing to move some shelving units. The general consensus seems to be on drain 
flies, thank you everyone that took the time to reply. I’ve attached an image I 
took of a trap that shows four flies right together. Hopefully the quality is 
enough to make an identification, I think a macro lens needs to be my next 
purchase!
 
Thank you everyone in advance.

A picture will help clear up the uncertainties. There are a few Drosophila

fruits. One species develops on fresh fruit, in fact.

Subject: [Non-DoD Source] [pestlist] Fruit Fly Question

Hello,

 

I have an odd question. I've been noticing the occasional fruit 
fly in my office area/washroom/work areas which are located in the basement of 
our building. I don't allow any kind of food on this level of the building, nor 
any drinks outside of water in resealable bottles and then only in designated 
areas with restrictions. Most of the time there's no one else on this level of 
the building and if there is I'd likely notice them bringing in food or other 
drinks. I haven't seen any fruit flies in the collections storage areas (woo!). 
There are exhaust vents in my work area and in the washroom. The washroom vent 
empties out into a crawl space under part of the building and I'm not sure 
where my work area vent goes but potentially the same spot. Some of the fruit 
flies have been getting stuck in the sticky trap in the washroom which is 
located by the door jam. I haven't noticed any fruit flies in other traps so 
I'm thinking they may be coming from there and potent  ially from the crawl 
space through the vent, though why t hey'd be in there I don't know. The main 
level of the building does have food friendly areas such as offices and a food 
service area for events but there doesn't seem to be an issue up there and I 
don't know how they would continually be getting down here as there is always 
at least one closed door to get, though generally more.

It's a scent free workplace so it's not like I'm wearing eau de 
pourriture fruits perfume down here!

 

Any thoughts?

Re: [pestlist] Powder Post Beetles

[bugman22]

Sarah -
 
First -  you do NOT have a Powderpost beetle "infestation".  The first photo  
shows a wide larval gallery and an oval flight hole.  The second photo shows 
lots of "bun-shaped" pelletized frass.  Both the first and second photos show a 
softwood board; not hardwood.  The third photo shows a click beetle in the 
center and what appears to be a ground beetle in the upper left corner.  
Neither beetle has anything to do with the damaged boards.
 
What you have are galleries and damage from larval tunneling of the Old House 
Borer, Hylotrupes bajulus.  Although it is called the old house borer, it often 
rides into new homes in the form of larvae already in the wood.  Standard 
kiln-treating lumber does not kill the larvae.

Unless I know more details, I cannot tell you if it's active or inactive.  Most 
of the time, especially in old buildings, the infestation was built into the 
building and has long since died out.

Hi everyone,
 
I have recently had a few unwanted visitors in our basement level storage 
(primarily textiles and ethnographic materials). I have attached a couple of 
blunder trap images with a tape measure in centimeters for scale.
 
I believe the first image shows a hide beetle, partially chewed by the adjacent 
smaller beetle (black carpet beetle?). Can anyone confirm? I have very 
occasionally had these before.
 
On the second trap, the black one at the top I have also seen before and have 
been previously told it was a mealworm beetle. The two lower ones are new to me 
and appear to be the same species as each other. The photo doesn’t show it 
well, but they are an iridescent copper colour. These were on a common blunder 
trap that was near a pheromone trap for beetles (I’m experimenting) that has 
attracted larder beetles – may be a clue?
 
Any thoughts?
 
Thanks,
Dee

As an entomologist and one who has spent his career setting up Integrated 
Preventive Pest Management (IPPM) programs for museums, historic houses, 
collections, libraries and archives around the world for the past 41 years, one 
must consider what kinds of pests may be considered pests of collections or a 
structure.
 
In reviewing the list, I would consider certain kinds of carpet beetle adults 
(feed on pollen), cigarette beetles (feed on dried plant materials), and 
drywood termites and wood-boring beetles (wooden natural materials and objects) 
to be of concern.  
 
Carpet beetle adults tend to feed on composites and bridal veil.  So 
chrysanthemums and daisies might be of concern.  However, if we are talking 
about cut flowers, I do not consider even these to be a problem.  When a carpet 
beetle adult is disturbed, it folds its legs and antennae into grooves of its 
body and rolls off the flower like a lead shot or B-B.  Or they may just spread 
their wings and fly away as the flower is being cut.  Roses, tulips, daffodils, 
and all sorts of other kinds of flowers would be fine.

Cigarette beetles are often found infesting dried flower arrangements and dried 
plant material on display, such as a string of dried chile peppers.  The are 
also a "bookworm" where the larvae feed on the glue of the binding.  And they 
often feed on paper mache items, such as mortuary masks and puppets.

Wood-destroying insects should be considered when felled logs and branches are 
being considered.  Powderpost beetles should be considered when donated 
furniture arrives from Aunt Ida's basement or attic.  Or the contents of a 
cobbler's shop.
 
What is equally important is what kinds of traveling exhibitions and temporary 
demonstrations does management allow.  For instance, never allow a weaver to 
set up shop in a museum; these well-intentioned demonstrations often infest 
museums with webbing clothes moths.  And don't use real wool in your diorama of 
pioneer life; use synthetic "wool".  The same goes for the importation of woven 
woolen items into a museum shop.  Taxidermy mountsugh.

I can't think of any reason succulents are on the list, if we are just talking 
about insect infestation.  The same goes for plastic or silk or waxed flowers.  
Carpet beetles do not feed on plastic, silk, or waxed flowers.  Carpet beetle 
larvae require keratin (an animal protein) in their diet; silk is a mineral 
spun from the salivary glands of a moth larva.  It does not contain keratin, 
even though you see time and again references to carpet beetles feeding on silk 
in the literature; it's simply not true.  Silk damage is usually caused by UV 
light and silverfish feeding on the sizing.

That brings me to silverfish.  Every time you receive a cardboard box into a 
museum, you run the risk of importing silverfish inside the corrugations of the 
box.  Box manufacturing plants are loaded with silverfish.  They feed on the 
glue and labels.  So what is one supposed to do?  Nothingthat's life.  
Insure you have a thorough IPPM program in your institution with lots of 
glueboards.

You have an outdoor pest - no threat to collections.  However, if you allow 
larger dead insects (large flies, wasps, beetles, American cockroaches) to lay 
about your building, carpet beetle larvae will devour them, leaving piles of 
frass in their wake.  The adult carpet beetles will readily fly to other 
sources of protein in your building and lay more eggs.

Good morning from Madrid
Yesterday we found two alive bugs (one of them at the photo) that we identify 
as cerambycidae, specifically Plagionotus Arcuatus, very close to historical 
books. We dont know these guys are indoor or outdoor pests. They like eating 
historical paper? we are very concerned about that. Any advice will be grateful.

Many years ago, I had the same kind of infestation in the frames of old

I've also run into them - a large infestation of"bookworms" in a library in 
Israel.  Anobium punctatum is a fairly common wood-boring beetle in Europe.  
I've run into it only once here in the U.S. - an infestation in a bedroom floor

We have just received a shipment of drawings and on opening the crate we 
discovered several dead specimens of the beetle shown in the attached photos.  
Beneath the layers of drawings is an old wooden architectural fragment that the 
beetles have been tunnelling through with great enthusiasm.  There are huge 
amounts of frass. 
 
We sealed the wrapped the crate in plastic sheeting , and plan to have it 
treated by anoxia with CO2.
 
What kind of beetle is this?  We don’t have a lot of experience with 
wood-boring insects.

Group -

It sounds like the applicator is going to use an aerosol or fog application of 
Gentrol --- NOT good for any collection.  Pesticide applications are short-term 
"fixes"; you really haven't found the reasons infestations exist and aim 
prevention methods at them.

And yes, it will hold larvae in the larval state where they will keep on 
feeding.

It's time you had someone set up a proper IPPM (Integrated Preventive Pest 
Management) program for your facility, which would basically eliminate the need 
for any pesticides (except for your termite situations).

For instance, there are readily-available pheromone traps for drugstore 
beetles.  Wouldn't it be more logical to have a thorough inspection and find 
out the source of the drugstore beetles?  Is it old rodent bait?  Is it some 
sort of dried plant material?  Or is it someone housing cooking spices 
somewhere nearby?  Is it an accumulation of pigeon droppings in an attic or an 
exterior ledge?  Same could be said for the cockroaches - why are they present 
and where is the source?  If it's American's, they are probably walking in.

We already spray the exterior of the building with esfenvalerate, which has 
helped tremendously preventivng new critters from getting in.  However, we 
still need to address our resident populations.


My understanding is that Gentrol (hydroprene) will also affect a handful of 
other common pests, including drugstore beetles.  Our biggest concern about 
using this product is how the IPM coordinator for our campus described how it 
is used.  He made it sound like the chemical travels through the building, or 
at least parts of it, meaning that it touches everything.  We're used to target 
spraying, but the idea of a chemical floating through the air and coming into 
contact with photographic collections does raise a concern.


Another concern we are curious about is if Gentrol arrests development of 
larva, do they stay in the larval stage longer and cause more damage to 
whatever they are feeding on as a result?


Mostly I'm interested in hearing if anyone else out there has tried IGRs and 
what their experiences are.


Thanks,


Alan

Insect growth regulators do not work on all insects across the board.  They 
work primarily on cockroaches and fleas.  They disrupt the molting process of 
cockroaches and hold fleas in the harmless larval stage.  They would not be a

Hello PestList,


We've been approached by our campus IPM coordinator about using insect growth 
regulators within our building.  Being as that we are the home to not only a 
large collection of books and manuscripts, but photographs as well.  If we were 
just a regular library, I'd say to go for it, but we aren't.  What is the 
current thought on using IGRs in cultural institutions, especially those with 
chemically sensitive collections?


Thanks,

Alan Van Dyke

These red mites are quite common crawling up the exterior of buildings and 
entering through the weep holes in the lower frames of windows.  They are 
originating in the moist leaf litter and mulch around the perimeter of the 
building.  You'll have to check with Lou, but I think they are predaceous.  The 
only damage they cause is a red smear if crushed.

Red snout mites are members of Bdellidae; this one looks more like an 
Erythraeidae.

Hello everyone,

I found this little guy (less than 1 mm) near our library, which is on the 
third floor. My first guess is that it's a mite, but since it was by our 
library, I wanted to be sure it wasn't something more harmful.

Thank you!

Insects Limited, Inc. manufacturers an extensive line of pheromone traps.
 
However, an insect electrocutor unit, mounted low and hooked to a timer works 
quite well for all the carpet beetle species adults.  Time it for 3 or 4 hours 
a night when the storage area is dark.

I work for a private design collection of clothing/accessories that around this 
time of the year start to spot some dermestid beetles that our pest control 
provider has identified as black carpet beetles (this is by no means an 
infestation, just seasonal activity we are trying to keep controlled).  Last 
season, our pest control provider gave us some “carpet beetle” traps that were 
later proved ineffective: our traps caught nothing even though we had continued 
sightings of a few flying around and later our pest control provider said the 
same traps were used in an absolutely infested space and were unable to trap 
anything.  They have been unable to recommend another trap.  I looked around on 
the Trapping section on Museum Pests, but I figure direct endorsements are not 
polite.  I am unsure of the brand they were using here, but the pheromone vials 
were placed on yellow Catch-It glue traps.  Perhaps the Catch-It was not sticky 
enough for a beetle as well...


If anyone does not mind making a personal endorsement, can you please recommend 
a specific brand for black carpet beetle pheromones?  




Thank you!

Britta -
 
Bed bugs must suck blood in order to grow and produce eggs.  Obviously in a 
museum setting, bed bugs won't have an opportunity to suck blood from a host.  
There may be a random bed bug dropped by some visitor.  It would be nothing to 
get excited about.  Good housekeeping and vacuuming should do the trick.
 
However, an employee locker room may have more than a couple of bed bugs if 
some employee's home is infested.  They may repeatedly bring in bed bugs to the 
locker room.  This may require some sensitive investigative work to identify 
the source.  It may also require a professional pest management firm to treat 
the entire locker room and all the lockers.  If the source is not identified, 
the locker room will once again become infested.

The final situation is a cloak room for visitors.  Here too a random bed bug 
may ride in on someone's coat.  Except for the bad publicity, if were noticed 
by a visitor, this incident will not result in an infestation.

I know of no official policy of an institution for referral.  Sorry.

Tom Parker

I recently started a position in Chicago, a city that has a history of bed bug 
infestations (as many large cities do). As the IPM coordinator at my museum, 
I’m wondering if others have developed any policies/procedures to limit 
potential infestations, to monitor bed bugs specifically, and to respond to 
identified infestations. I’ve already learned quite a bit about identifying 
them in the museum environment, so I’m hoping to gain knowledge about what to 
do if one is found. Feel free to respond to me off-list.
 
Many thanks,
Britta

Friends -

Early last week, someone claiming to be me, hacked my AOL account and sent a 
fraudulent email to my entire contact list.  This creep stated he was in Spain 
with a sick cousin and wanted you to send him $2,500.  DO NOT SEND ANY MONEY!  
I am not in Spain, nor do I have any relatives in Spain.  This guy is a fraud.  
I am so sorry this happened.  I hope this event did not cause you any undue 
stress.

Sincerely -

John -

The height and location of a light trap depends on what you're trying to catch. 
 If it's houseflies, then the trap should be no higher than 5' off the floor.  
If it's an indoor light trap in an attic for incoming pests in the fall of the 
year, then it can be placed on the floor surrounded with glue boards.  This 
type should be place on a timer to go off during daylight hours.  If it's an 
outdoor trap (not recommended), then it should be placed away from the 
building.  If it's for carpet beetle adults indoors, it should also be placed 
on a timer and go off during the day.  During the day, adult carpet beetles 
will be attracted to the windows and light fixtures.

Greetings group,
 
We’re seeking advice, technical guidance and wisdom borne from experience 
regarding the optimal locations for our UV light traps. 
 
We are discussing with our pest control vendor ways of improving the locations 
for our UV light traps.  The field rep. for our vendor stated that the ideal 
height for UV light traps is six to seven feet above the floor because - 
according to the rep. and I’m paraphrasing - that is the level at which most 
museum pests fly.  We like the services our pest control vendor and our field 
rep., provide.  They are very responsive to our needs.  However, we must get 
more prevention from our UV light traps and would appreciate hearing the 
group’s collective wisdom regarding optimal locations.  Is there any truth to 
the fly height?  Is there a standard height from the floor to mount UV light 
traps?  Please contact me off-list if necessary. 
 
Many thanks.

You actually have the shed exoskeletons of two different kinds of dermestid 
larvae.  One looks like it's in the genus Anthrenus and the other one (pair) 
looks like it's in the genus Trogoderma.  No telling how long this skins have 
been there.  It's not unusual to find these protein eaters in a coffin.

Dear Pestlisters,

A colleague working at another museum has been faced with the problem of 
cleaning a diorama populated with museum objects, reproductions and props that 
have been in contact with mice (droppings, gnawing, etc.). Mice infected with 
hantavirus are a known problem in the region where this museum is located. I 
understand that UV exposure is an effective way to degrade the virus but I 
wanted to know if anyone has any further recommendations for treating/cleaning 
objects exposed to infected mice.

Thanks for your help,
Beth Holford

Kudos, Jenny.  Our participants have to realize the primary vectors of 
Hantavirus are the deer mouse, white-footed mice, pack rats, and cotton rats.  
The city mouse vs. the country mouse is not a vector.  The city mouse is Mus 
musculus and has not been indicted.  So individuals should first know what 
mouse they're dealing with.  If it's the city mouse, then the probability of it 
transmitting Hantavirus is extremely low.  If it's a country mouse or a pack or 
cotton rat, that's a different story.

HI All,


We (National Park Service - NPS) are developing new training materials and 
guidance on this topic, specifically. We are working with officials at the CDC, 
so the information will be consistent with their recommendations, as well.


I believe I am familiar with the (NPS) museum you are referring to, Beth. We 
will also be providing recommendations, via an updated Conserve-O'Gram 
technical bulletin, for risk reduction and risk elimination in specific 
situations we encounter in collection storage, exhibit areas and historic 
structures. This information will also be available to other institutions and 
the public via links on the NPS.gov website.


Regards,


Jenny Leasor

I can guarantee you have strong lights attached to your building where these night flying scarab beetles hit the light and building and then drop to the ground. They are walking into your building. It's time for brush sweeps on your doors.

Hi all,



I’m not worried about these two beetles, just curious as to what they are as we are seeing them in the building more. The first two photos are of the same beetle. The third is on a different trap but looks the same as the first. The third is mostly brown, found on a different trap. Not found en masse, but here and there on the same floor and end of the museum building. It will be good to note the time of year so when next year rolls around we’re not surprised (we hope). 



Thanks for any help!

Barbara -

Sampling the air for mold spores is useless unless samples are also taken 
outdoors in order to get a base level for your building.  I've often been 
involved in such situations.  Mold spore counts on a petri dish indoors or with 
an air sampling machine mean nothing.  I had a situation where mold spores were 
sampled indoors and blamed on bats in the attic.  When the counts were taken 
outdoors, they were three times the amounts indoors!  I guess the bat 
infestation really wasn't that bad after all, at least not for the mold counts.

If you want to know the kind of mold you have, then wipe samples from the 
object are best.  Find a large hospital with a mycology department.  They will 
plate out your wipe samples and tell you what you have.  I usually donate a 
nominal amount to some cause the mycologist might be championing for plating 
out the samples.  If you just get an ID to genera, that's not real helpful.  
You need the genus and species of mold.  For instance, Aspergillus Is a very 
common indoor mold.  There are all sorts of species in this mold genus, which 
really aren't that big a deal.  However, the bad guy is Aspergillus fumigatus.  
Unless you know the species of Aspergillus, you really can't make logical 
decisions about isolation and remediation.

I've been involved in mold remediation primarily in libraries where elevated 
humidity causes mold blooms on the books and other items.  Books really suck up 
moisture from the atmosphere and create perfect micro-climates for spore 
germination and mold growth.  The cause is usually an HVAC unit out of whack.

What are the differences between wipe samples and air testing?
Is one or the other easier, cheaper - or better in some other way?


If there is no control data - from before a mold problem occurs - is one 
sampling diagnostic?

Dr. Carey -

In Israel, I had a shipping container (the kind you see on ships and trucks 
at docks) capable of reaching similar temperatures dropped in a secure parking 
lot for freezing almost 30,000 books infested with bookworms.  For delivery and 
pick-up after we had finished, the thing cost only $600/month.

It would be helpful for the readers to know the name of the nationwide 
company, so others could avail themselves of this approach if the need ever 
arises.  It would also be helpful if you included the exact product names and 
manufacturers of your monitoring devices.

Thank you for this important and practical information.

Annie,


Last August we discovered a webbing clothes moth infestation in the African 
collection. With over 200 objects a lab freezer was out of the question, though 
a used Revco or Fisher Scientific freezer would be perfect for small groups of 
items needing treatment.


I had an 8' x 20' walk-in freezer delivered from a nationwide company. They 
dropped it off in the driveway. I needed to provide 230 volts. It took a week 
to wrap, double bag and heat seal all items. Meanwhile, the freezer was getting 
cold in the hot, humid Amherst summer.


Although only rated down to -20 C, the temps actually ran around -33 C. During 
12 hour defrosts, the temps rose to only about -23C. I placed 2 inexpensive USB 
data recorders in the freezer, plus a wireless Temp/RH monitor with an alarm 
set for -20. I've attached a graph below.


The objects were frozen for about 2 weeks, much longer than needed.


This setup would be perfect for immediate and occasional needs for large 
collections. For frequent usage, purchase makes more sense than rental.

Annie,
I believe that the image jonesh3.jpg may be a dealated formosan termite 
swarmer. A clearer view of the wing remnents could clarify. If this was 
captured recently it more or less coincides with formosan swarming in New 
Orleans.

Hello pest list,
 
I have attached four images: three of which I believe are different phases of 
the odd beetle, but am looking for some confirmation of that. I had thought 
that all the larvae I was finding were carpet beetle larvae, but now am 
rethinking that as I find what I think are odd beetle adults. But it seems as 
though they both raise similar concerns in relation to library collections.
 
I don’t have a clue of what the thing pictured in the image titled jonesh3 is, 
can anyone ID it?
 
I’m also putting a query out there about a freezer. I’d like to get a freezer 
for our institution that will be used for incoming gifts and possibly as a 
mechanism for treating a large collection in the process of moving it to a new 
space. I’ve found a mini walk-in room that’s in our budget, but it 
automatically defrosts, raising the air temperature to about -15C every 6 
hours. The company has told me that items stored in it only warm up about 2 or 
3 degrees during the defrost (from -20C) but this still makes me concerned 
about its pest killing abilities. Am I right to be concerned about that, or 
will it be effective in treating collections materials for pests?
 
Thanks,

Leslie -

I have to disagree with Ryan.  It's not an Oriental nymph; it's an American 
cockroach nymph.  It has turned fairly dark as it has dried out on the glue 
board.  The telltale ID feature is it's reddish brown, at least in the anterior 
portions; the posterior has turned dark as it mummified.  More importantly look 
at the yellow border at the edge of the pronotum.  Now Google Oriental 
cockroach photos and you'll see all sorts of photos of Orientals and Americans 
(plus a few PA woods roaches thrown in to boot) and you'll see the Oriental is 
totally black, even the nymphs, and the American has that yellow border around 
the pronotum.

Access Studies in Pest Control for Cultural Property




CCI's Tom Strang, Senior Conservation Scientist and internationally recognized 
expert in integrated pest management, recently defended an academic 
dissertation on Studies in Pest Control for Cultural Property at the 
Department of Conservation, Faculty of Science, University of Gothenburg, 
Sweden. 

Strang's research involves the problems of protecting cultural property from 
pests and examines some of the solutions. The use of fumigants and pesticides 
to protect collections of cultural property has changed to reduce health 
hazards and adverse interactions with materials. Alternatives, such as thermal 
treatment and controlled atmosphere fumigation, have replaced applied residual 
chemicals and exposure to reactive gases in many applications. The shift has 
introduced new risks, however. Establishing efficacy, considering side effects 
of unfamiliar control applications, and deciding how to construct systemic 
programs to reduce the risk of pest damage across a wide range of conditions 
are common challenges to the decision process. Strang's research introduces 
sufficient data and discusses complicating factors in order to address key 
concerns and enable collections care professionals to have greater confidence 
in their decisions regarding pest management.

Insley -

The basement from which these items came had an infestation of subterranean 
termites.  Once they were removed from the basement, that was the end of the 
activity.  You're left with damage and lots of soil.  Termites wall themselves 
off in humidity-controlled chambers and tubes by glueing soil grains together.  
The workers make trips back and forth to the soil to bring soil grains up to 
their workings.  This situation is NOT active and there is no cause for doing 
any treatment, except of course, cleaning the materials.

Hello,
I just started work at a very small museum with archival collections.  When I 
arrived, I came across an accession which was previously stored in the basement 
of a large wooden structure (by the donor), and is/was? clearly infested with 
some sort of insect.  This infestation and the ensuing damage occurred prior to 
the museum taking custody of the records.  I am wondering if someone can tell 
me from the photos what I am dealing with?

What I believe is frass, appears as brown specks, which are adhered to the 
paper, but there is also granular, sand-like material in the envelopes in which 
the material is stored.

It's difficult to tell if this is all frass or if the material is just really 
dirty, which is also possible.

It is also hard for me to tell what might be frass and what might be eggs.  
I've found a few specks which appear to have web-like material attached and in 
the interior fold of one item, spider-web-like material.

I've also found what appear to be shells/exoskeletons shed by insects, or 
possibly merely the remnants of dead insects.  Unfortunately, my camera doesn't 
have a high enough resolution to get a good picture of this.

I'm trying to figure out first what I am dealing with so that I can then decide 
how to treat the materials.  I'm an archivist by training and this is my first 
time dealing with any major pest issue.

I stumbled upon a powerpoint of insect frass online and the closest thing I 
could find was termites, since they excrete dirt as well as whatever else they 
are munching on.  Is it possible that this is termite damage?

I'm attaching some photos.  Sorry for the poor quality!

Thank you for any assistance you can provide!
Insley

Dr. Rauf -

We're talking about India!  The small water fountains are not significantly 
contributing the the overall humidity in the museum.  The high daily humidity 
results in the entire museum having an elevated humidity.  If there is no 
central HVAC system in the museum, then there's not much that can be done about 
humidity, except to keep air circulating so pockets of ultra-high humidity are 
not allowed to form.  Strategically-placed fans may help.  Even ceiling fans 
will help to circulate the humid air.

What's more important is installing a thorough glueboard program to monitor 
what's roaming around the museum.  The glueboard program will tell you what's 
present, densities of pests, and the direction from which they are coming.  You 
can then decide on building modifications to prevent movement and ingress.  In  
a humid environment, pesticide applications are but a temporary solution.

Without having some photographs of the museum, it's difficult to assess any 
further measures.

Tom Parker

Dear All,
 
We have to inspect one art museum’s big painting store. The museum admin., is 
asking an IPM Plan for managing the pests inside the Art Museum. There are 
small water fountains inside the museum in sculpture area. One can feel 
humidity inside in some outside rooms.  Give some guidelines specially for 
monitoring devices to be installed and the IPM.

Hi Linda,
 
There is a great little check list for identifying your requirements for an IPM 
in your facility.  Give it a look.

Linda -

 

Even on a skeleton budget, you can certainly install a thorough glueboard 
program very inexpensively.  Look at Atlantic Paste  Glue or Bell Laboratories 
on-line for their inventory of all sorts of glueboards.  You want those which 
will sit flat on the floor; not plastic trays.

Hi Amy,

I’d be really interested in seeing what responses you get and hopefully I will 
via Museumpests.net.   I’m currently looking at the cost effectiveness of IPM 
in small museums and how it can be carried out on a very small or non-existent 
budget, so this information would be very useful.

 

Kind regards

Yes, Lou, you're correct.  It is probably a gnaphosid.  I knew it was a spider 
egg case but my advancing age wouldn't let me remember which one.

Tom,
Sorry, Tom, I’ve been reviewing the images and I have to disagree with a 
determination of salticid egg sac, let alone Phidippus.  While P. audax can be 
very commonly encountered species, it does not produce a sac that looks like 
this.  The egg sac looks like it belongs to a corinnid or gnaphosid spider.  
The older literature would list many of the corinnid species as belonging to 
the family Clubionidae.  
Hi Ingrid Neuman, RISD Museum of Art.  Are you able to collect the egg sac and 
send it over so I can examine it, take out the exuviae within.  Would be a 
problem if they were infertile eggs, however?

I am interested in finding out information about insect threshold levels in 
museums and collections.  Obviously, insects can get into buildings and be 
found on monitoring devices such as sticky traps, but they do not warrant any 
type of control.  How do you determine control when nothing in particular is 
infested?  Any resources on threshold levels would be greatly appreciated.
   
Thank you,
Amy K. Miller

It looks like a cigarette beetle (Lasioderma serricorne) to me. Was the wooden 
bject associated with food (e.g. grain bins)? We have found cigarette beetles 
n wooden Aboriginal food carriers (coolimons) where food residue had penetrated 
he timber.

Rosa -

Drywood termites can invade a variety of spots in a structure.  They may have 
made their way into the substructure or other elements.  I think the Pest 
Management Professional is covering all his bases by recommeding a full 
fumigation with Vikane.  This will absolutey wipe up everthing.

I am working on a small historic house that is being renovated by its owner.  
In removing insect damaged maple parquet floor tiles they found live termite 
larvae. They were identified by a fumigator as drywood termites but I'm not 
sure it's true.  The damaged boards have all been removed but of course we 
don't know if the termites are there in other boards.  So the question is:  To 
tent or not to tent?  This is an empty building at present, in Florida.  Are 
there other reliable methods for getting rid of these pests?

I have an infestation of brown-banded cockroaches in my kitchen and dining 
room.  I found where the egg-sacs were - in a drawer of linens in the dining 
room - so I put the linens through a very hot washing cycle, took everything 
out of the stand-alone china cabinet, pulled the drawers out, and killed 
everything I found.  No activity for about a week, and now they're coming back 
- mostly in my kitchen, where I haven't been able to find any eggs. 


I pulled out my refrigerator and checked the coils, I've looked behind the 
pictures on the walls, unscrewed outlet covers, etc. -  no signs.  Unlike my 
German friends, it doesn't seem that they are coming out of the walls; I am not 
finding any in kitchen cabinets.


I'm assuming that the ID is correct, although I've never seen one fly.  They 
mostly hang out high up on walls, and are very placid - they don't run for it 
when someone comes close, they don't scatter when the lights are turned on, and 
I don't see them on my kitchen counters at night.  I don't  know what they're 
eating.


I would be eternally grateful for info!  Any suggestions?

Simply put a 100 watt light bulb in the cabinet and close it up.  The heat 
generated by the light bulb will slowly dry out the materials and that will be 
the end of the psocids.

Hello,
 
I am curious what others are using in their collections for general pest 
control and if anyone has had psocids visiting their collections.  I’ve just 
discovered psocids in an insect and herbarium cabinet and am interested in 
finding out if anyone else has had this issue and how it was corrected.  
 
Thank you,

Put the book (if it's not a rare one) on the top rack of a household oven.  Put 
a pan of water on the bottom rack to keep the oven and book humidified.  Turn 
the oven to the warm setting, which is 170 degrees F.  Leave it in for an 
hour and then turn off the oven.  Once it has cooled down, remove the book.  
All stages will be easily killed.

Low temperatures of close to 0°F for 3 days was the most recent bit of 
information to kill bed bug eggs, nymphs, adults.
Also from the U MN bed bug website:
“However, based on related research, a two-hour core exposure at 120°F (45°C) 
should be considered a minimum target temperature for heat treatments. For 
freezing, a minimum of 23°F (-5°C) must be maintained for at least 5 days. As 
the temperature is decreased, the time of exposure is shortened. For instance, 
the articles could be “flash frozen,” resulting in a very short time of 
exposure, but the target temperature should be -15°F (-26°C), the conditions 
required to instantly freeze the eggs. Keep in mind that most household 
freezers will have varying temperatures between 30°F and 20°F, and a 2-week 
freeze time is recommended if you are uncertain of the freezer temperatures.”

Hi everyone,
Any comments on this recent story on bedbugs in the NY Times? If people don’t 
want to use heat treatment and have access to low temperature and follow the 
protocols, that should work, right?

Barbara -

 

The rule-of-thumb is 130 degrees Fahrenheit for 3 hours will kill any stage of 
any insect.  When pest management firms super heat a home for bed bugs, they 
leave the heat for the better part of the day to insure it reached that level 
in all materials and areas of the home.

 

When it comes to killing insects in wood, commercial kiln-drying of lumber only 
reaches about 108 to 115.  Often larvae in wood are not killed in the kiln 
because the wood is a good insulator.  I've been involved in powderpost beetle, 
wood-boring wasp larvae, and old house borer infestations in kiln-dried lumber, 
including hardwood flooring.

 

An easy method for items of lesser value, is to place a pan of water on the 
bottom rack of a kitchen oven in order to maintain high humidity in the oven.  
Place the object directly onto an upper rack.  Then turn the oven to its warm 
setting, which usually is 170 degrees Fahrenheit.  Leave the object in for 3 
hours and then turn the oven off, leaving the  object inside.  When the oven is 
cool, you can remove the object.

 

I've used this method for powderpost beetles in objects purchased by tourists 
in various countries.  It can probably also be used for certain kinds of 
fabrics made of natural materials.  I would not try it on synthetic fabrics; 
they might melt.

Dear all,
 
One of our conservators is talking about using potato flour as part of a 
cleaning process for taxidermy. Although the flour is blown out of the fur/hair 
at the end of the process, I am concerned that any residue could potentially 
provide a food source for pests. I was wondering whether anyone has any 
experience of using potato flour on taxidermy, and whether or not it has made 
the taxidermy even more appealing to pests?
 
Many thanks in advance,
Abby

Dr. Rauf -

The use of Imidachloprid, known as Premise in the U.S., is a termiticide for 
use by professional pest management firms only.  In order to control 
subterranean termites, it is injected or trenched and flooded into the soil.  
It can be used on the exterior and interior of a building, depending on the 
source of the termites.  It is NOT simply a spray, which can be used by a lay 
person; it must be placed in the soil where the termites originate.

A better choice, if it's available in India, would be fipronil, known as 
Termidor in the U.S.  It is much less water soluble and will therefore have a 
longer residual life in the soil.  Again, both of these termiticides should 
only be applied by a professional.

As far as insects damaging to library materials and manuscripts in old 
libraries, I have found the following to be problems:  bookworms (beetles, such 
as Anobium, Stegobium, and Lasioderma), silverfish, booklice (Psocidae), 
American cockroaches, and sometimes certain species of carpet beetles to be the 
primary pests.  Of course, mice and rats can also chew up paper-based materials.

It would be helpful if you told us where this library is located?  Imidachoprid 
is illegal to be used in certain countries.  It would also be helpful to know

Dear All,
 
The library is housed in an old palace. It has a vast collection and manuscript 
divisioin containing very old collections. We would like to know the follwoing:
 

What are the major insect pest inside old libraries? 
For termite infestation in wooden panels and cabinets, can we use Imidacloprid 
30.5%SC formulation inside the library. It is used after mixing with water. It 
will certainly increase the relative humidity. 
What are the preventive IPM Measure to be taken there?

Regards.
 
Dr. Abdul Rauf

Leonie -

If you simply set the pieces out on a table for a few days, they will lose most 
of the moisture in your heated building.  They would then be able to be frozen 
without incident.  Be careful of any adornments on the pieces and be sure 
freezing wouldn't affect them.

If the wood in the photos is a softwood (white pine, fir, hem-fir), then it's probably OHB. Many of the holes look old. The larvae may have ridden in with the columns and logs when they were installed and you are just now seeing a small bit of activity. Perhaps you can simply replace these elements to rid the place of the infestation.

Director Timothy -

Oklahoma is a hotbed of Brown Recluse Spiders.  In order to give you some help 
with your situation, I'd have to know more about the construction of your 
building.  Is there a basement?  A crawlspace?  What surrounds the building?  
Does anyone actually live full time in the building?  You've certainly made a 
dent in the population with your trapping program.

In the ongoing commentary about the Brown Recluse in Oklahoma, fogging a 
crawlspace is very effective against all spiders.  Either natural pyrethrum or 
synthetic pyrethroids are dynamite in this kind of situation.

And in answer to Lou Sorkin's comments, yes, I have found Loxosceles rufescens 
in several locations in Philadelphia.  I was sure they were L. rufescens, but I 
relied on Lou graciously positively IDing them.  They are breeding populations. 
 It seems they're located in the municipal underground steam lines to a variety 
of private and municipal buildings in center city Philadelphia and under the U. 
of Penn campus.  I've trapped hundreds in several situations.  These are not 
ones occasionally introduced; no, these are breeding populations.

Let's start with two questions: 1.) What do they appear to be feeding on?; 2.) 
How are the spiders and prey getting inside?  Most insecticides fail because 
the spiders do not actually come in contact with them.  Fogging can be very 
effective, but fogging can be highly deleterious to objects and artifacts 
within the museum.  The answer to the problem is to reduce or eliminate access 
for both spiders and prey by tightening the building up as much as possible.

Heat treatment forstored productpests in grain silos, food plants, and certain kinds of warehouses has been practiced on a large scale for decades. The temperature needed to kill all stages of any insect is 130 degrees F. for 3 hours. We're not talking about temperature ranges which would affect DNA. Certainly large scale heat treatment of grain silos has not affected the grain'sgermination rates orits DNA.

We are having trouble with pest infestation in our herbarium and are considering heat treating instead of fumigation with toxic gases. (We are already working with cleaning the rooms, freezing and bagging of specimens but it is not enough). Isthere anyone with experience of heat treatment in large areas or maybe hasany documentation?We are mostly concerned about theeffect on DNA.





Thanks for any information

I hope the pest management firm put the Nuvan strips in their cardboard pockets 
so the strips themselves wouldn't touch the books.  If the strip(s) touched the 
books, some of the Vapona may have migrated into the covers.  Not a good thing.

If they've done the fumigation correctly, as long as you've allowed the books 
to aerate for a few hours, you can vacuum them and return them to circulation.

'm hoping that some of you can help with advice on bed bugs and treatments for 
ibrary materials.
We have had three separate incidents of books (all hardcovers) returned to the 
ibraries with bed bugs hiding in the spine hollow.  In one instance, there were 
t least five live bed bugs in the affected book, along with an egg on the 
eadband, and staining on the textblock near the spine hollow.
One time the affected books were bagged and a pest control company inserted a 
UVAN strip for two weeks:
ttp://www.myadapco.com/res/pdf/msds/Nuvan%20MSDS.pdf
We've been told that we can now return the books to the collection as long as 
we 
llow the materials to off-gas for 2-6 hours.  Given this treatment, would it be 
afe to return these to the circulating collection for use and to have our 
onservation staff vacuum the affected books?
In another incident, we bagged all the books and put them in a walk-in freezer 
at least -20) in another location on campus.  We did 7 days in the freezer, 6 
ays out, and are planning another 7 days in the freezer.  Would you recommend a 
horter cycle/combo for a -20 freezer?  And if we used a 0 freezer, what cycle 
ould you recommend?
While we know that the bed bugs won't damage books per se, we want to make sure 
hat they don't find a home in our facilities over time.
Thanks for your help!

Barbara -

The rule-of-thumb is 130 degrees Fahrenheit for 3 hours will kill any stage of 
any insect.  When pest management firms super heat a home for bed bugs, they 
leave the heat for the better part of the day to insure it reached that level 
in all materials and areas of the home.

When it comes to killing insects in wood, commercial kiln-drying of lumber only 
reaches about 108 to 115.  Often larvae in wood are not killed in the kiln 
because the wood is a good insulator.  I've been involved in powderpost beetle, 
wood-boring wasp larvae, and old house borer infestations in kiln-dried lumber, 
including hardwood flooring.

An easy method for items of lesser value, is to place a pan of water on the 
bottom rack of a kitchen oven in order to maintain high humidity in the oven.  
Place the object directly onto an upper rack.  Then turn the oven to its warm 
setting, which usually is 170 degrees Fahrenheit.  Leave the object in for 3 
hours and then turn the oven off, leaving the  object inside.  When the oven is 
cool, you can remove the object.

I've used this method for powderpost beetles in objects purchased by tourists 
in various countries.  It can probably also be used for certain kinds of 
fabrics made of natural materials.  I would not try it on synthetic fabrics; 
they might melt.

I've found boxing up the materials, loading them on pallets, and then 
shrink-wrapping the pallet makes it much easier to transport to a commercial 
freezing operation.  They can easily handle the material with their fork lifts. 
 Usually commercial freezing operations keep their rooms at 0 degrees 
Fahrenheit.  I would leave the materials for at least 10 days in the freezer.

Hello,
 
I was referred to this list as a possible resource to help answer my question.
 
Does anyone have experience accepting large donations that may be infested with 
pests? We are in the process of planning the move of 700 + linear feet, of 
primarily paper-based materials, from a building that has not had power for 
years. I have concerns about integrating these materials with existing 
collections. My first thought was double-bagging every box and dropping them at 
a commercial freezer for a week before we receive the materials. Does anyone 
have other suggestions that may not be so labor intensive?
 
Any suggestions would greatly appreciated.
 
Thanks,
Scott

Group -

Here's a question for those of you who may have had an occasion to battle a 
heavy infestation of plaster beetles:  Let's say there's a roof leak causing a 
mold bloom, hence an uprising of plaster beetles.  Then the leak is repaired; 
the mold no longer grows, but a billion spores are left behind.  Can plaster 
beetles still survive and reproduce in the dried out mold by the larvae eating 
the spores and mycelia?  Or once the mold is dried out, is that the end of the 
reproduction and slowly the adults will die off?

Any thoughts?

It's a Latridiid, and I concur on Adistemia. Depending on the trap location, 
two may not be indicative of an infestation. These guys don't need much to eat 
and can hang around a long time after the conditions that triggered the initial 
mold growth are remediated.

Adistemia watsoni - one of the Plaster Beetles (Latridiidae). It is sometimes

So you have mould somewhere. Getting rid of the mould will get rid of the

Hello,

I've recently found these flying insects inside and outside of the historic 
building in Virginia where I work.  I don't recall ever seeing them before, but 
this June they are out in abundance.  They are just under a centimeter in 
length and are yellow-green in color [please see attached photograph].   I'm 
new to IPM and have checked all of my resources without coming up with an 
identification.  Could they be fungus gnats?  Any help would be very much 
appreciated.  

Thanks,
Kate Hughes

Abby -

Brush sweepers have many advantages over rubber seals.  They conform to 
irregularities over which they ride; they will not be chewed out by rodents, as 
I have often seen with rubber seals; and they will effectively keep out rats, 
mice, snakes, and all manner of insects - even scorpions and spiders.  You can 
even install brush sweeps on overhead doors, in between double doors, and on 
dock load levelers.

A major company providing these products in all kinds of sizes is the Sealeze

Dear all,
 
I was wondering if anyone has a preference when it comes to the type of seals 
used to prevent rodents squeezing underneath doors? We’re planning to have some 
fitted to a few internal and external doors, and the pest company we have asked 
to do the job have suggested brushes for the bottom of the doors. I would 
prefer rubber, as I’m concerned about insects taking up residence in the 
brushes, and I don’t know how successful brushes will be in stopping mice. 
However the company assure me that mice will not go through brushes as they 
don’t like the feeling. I’m not particularly convinced, so thought I would ask 
around. Does anyone have any experience in this area?
 
Thanks in advance,
Abby

Hello all,
One of our historic buildings, a log cabin, has squirrel issues.  We've
ried plugging the holes with hardwire cloth and copper mesh, but the
quirrels just pull it out and use it as nesting material.  The building
as double walls with a gap in between, perfect for stuffing with apples
nd raising squirrel babies.
A member of our maintenance crew brought in information about an ultrasound
mitter that acts as a repellent.  (This one is called YardGard.)  Does
nyone have any experiences with these kind of devices and whether they
ork?
Thanks,
am

Shae -

I do not call repelling rats from a kitchen...success.  You still have a rat 
infestation.  That's exactly what ultrasonic devices do; they repel rodents, 
they do not eliminate the problem.

In the case of the continual squirrel problem, I subscribe to live trapping and 
removal.  Squirrels are easy to trap with a Havahart type trap.  Close one end. 
 Use salted peanut halves as a trail leading into the trap.  Then place some 
salted peanuts under the front of the treadle.  The squirrel will commit 
completely into the interior of the trap and stick his blunt nose under the 
treadle to get to the trove of peanuts you've placed there.  Bingo!  One 
trapped squirrel.  It's best to put the trap out at night; the squirrels will 
be foraging early the next morning.  Take the squirrel at least a mile away and 
release it.  Keep doing it until the squirrels have been eliminated.

Kathleen -

Thank you for the update.

The reason one uses BoraCare instead of Tim-bor is it leaves twice as much 
sodium octaborate in the wood.

Do not treat any collection artifact with any borate or other topical material. 
 You will chemically alter the artifact for the remainder of its lifetime.

Hydrogen phosphide gas reacts with all sorts of metals.  It should not be used 
on museum artifacts.

I really cannot help you further because I have not had an opportunity to see 
your situation.  It's like asking the doctor to diagnose and prescribe 
without seeing the patient.

Hope things work out well for your building and collection.

Sincerely,

Tom Parker

To follow up:
 
We’ve had good help here from a University entomologist and some preservation 
architects, and have a contact at Forest Products lab, also, should we find 
need for it. We’ve determined at this point that the infestation is quite old, 
and very widespread, and that the affected woods are softwood, and therefore 
not infested with ‘true’ powder post beetles. 
 
A large portion of the building structure needs to be treated, and our pest 
control vendor is adamant that the entire surface of certain (not quite all) 
walls and all infested beams must be treated. I adamantly trust based on our 
interactions with him that he is making a practical choice based on his 
experience, and thus we are prepared to treat the structure to the extent he 
advises. Because of the vast amount of material stored within the structure, we 
also feel it is sensible to treat certain areas preventatively, in case 
something should be missed. Because it is such a large area, we are using 
Tim-Bor, rather than BoraCare, for the lower expense and greater ease of 
application. And it is Tim-Bor, as our vendor has a stock of it, regardless of 
it’s current commercial availability. 
 
As for the proposed fumigation treatment – the vendor thought all objects in 
the building would be treated, which is why he initially proposed fumigation as 
most economical. However, most non-collections items will eventually be 
discarded, and since the proposed fumigant is phosphine gas (which I am not 
comfortable treating collections with, and see from prior messages has not 
always been effective) we are investigating other options. While we may 
consider anoxic treatments, our best at the moment seems to be treating 
affected collections with an application of BoraCare. 
 
The question now in our minds is, do we treat these collections and leave them 
in situ for two years? One to allow the pests to eat their way through the 
treatment, and another to see if the treatment was successful and no more exit 
holes appear?  Ideally, when the infestation is gone, we would like to see 
collections moved to a better storage environment – which is available, 
however, we are fearful of spreading the infestation through our own mitigation 
efforts! 
 
 
Cheers,
Katie

Group -

 

Studies have shown a timber damaged by either powder post beetles or Old House 
Borers loses only 15% of its structural strength.  The reason is the galleries 
are tightly packed with powdered frass.  The larvae are not removing the wood, 
as do termites.

Think again.  Cimex is a very different creature.
Bed Bug Research at U MN
For freezing, a minimum of 23°F (-5°C) must be maintained for at least 5 days. 
As the temperature is decreased, the time of exposure is shortened. For 
instance, 
the articles could be “flash frozen,” resulting in a very short time of 
exposure, 
but the target temperature should be -15°F (-26°C), the conditions required to 
instantly freeze the eggs. Keep in mind that most household freezers will have 
varying temperatures between 30°F and 20°F, and a 2-week freeze time is 
recommended 
if you are uncertain of the freezer temperatures.
 
The temperature of your freezer is very important. The lower the temperature, 
the 
less time needed to kill bed bugs. Freezers set to 0°F are effective in killing 
bed bugs, 
but items must be left in the freezer for at least 4 days. If you are concerned 
about 
ensuring that temperatures are low enough, purchase an indoor/outdoor 
thermometer and 
monitor the temperature inside the items you are freezing. 0°F must be reached 
in the 
center of the materials being frozen to kill bed bugs. Bulky items require more 
time. 
Start counting the 4 day exposure time when the center of the object has 
reached 0°F.
Do not use temperatures above 5F (-15°C) as eggs and small bed bugs may survive.

If you happen to have bed bugs (funny I should mention them!) in boxes (I've 
seen office records with bed bugs from clients, workers, other people's homes), 
taking it down to 32F is no where near sufficient.  In fact, taking it down to 
-30F for a few hours doesn't kill them either; they just warm up and wake up 
after bringing the material back to room temp.

I was thinking more of the visitors. As I am sure you know, bed bugs do not 
just feed off humans, they will feed on any warm blooded animal. If you have 
rodents or birds living or nesting in close proximity to the building there is 
a risk, I agree a small one, that an infestation can become established.

Amber - it is hard to tell from the photo  but it looks like a female 
Thylodrias contractus (Odd Beetle).   It is a museum pest  - a dermestid. I 
suspect you have found them before - probably mostly as the larva form.  They 
are very common in museums. Could you send it over to me and I will take a look 
to verify - or I can stop by later in the week.

It is true about bed bugs; they're tough critters.  However, there's no way 
they are going to survive 72 hours at -20 F or -15 F, or even 0 F.

If you happen to have bed bugs (funny I should mention them!) in boxes (I've 
seen office records with bed bugs from clients, workers, other people's homes), 
taking it down to 32F is no where near sufficient.  In fact, taking it down to 
-30F for a few hours doesn't kill them either; they just warm up and wake up 
after bringing the material back to room temp.

In addition you need to realize that boxes of archives are very dense - and 
that paper is very good insulator. In fact, shredded paper is used to insulate 
houses in northern climates.  Given that, it is not surprising that it took 
time to reach the the desired temperature.  Be patient - the method works.

My rule of thumb (and Tom Strang and Mary-Lou Florian) is 72 hours.  For 
wood-destroyers, I recommend a first shot for 72 hours, let the materials then 
warm to room temperature, and then a second shot for 48 hours.  Since archives 
are so dense, this may be the scenario you need, although I doubt it.  You have 
to consider what might be infesting archival materials.  Booklice, silverfish, 
yes even bed bugs?  They are easy to kill with a 72 hour scenario.  If it's 
book worms (Anobiids), then the two stage effort will probably be required.

hanks Tom,
While the truck temperature reached 32 degrees F in 4 hours, the
emperature inside the box of records definitely did not.  The issue
ou raise- is one of my largest concerns- it took over 24 hours for
he internal temperature of the record box to reach 32 degrees- is
his so long that the insects can switch to hibernation mode and avoid
reezing or is 24 hours still quick enough to catch the insects off
uard and kill them?
To my knowledge we haven't found any insects (alive or dead) in these
oxes.  We are looking at this data in part to make sure that we are
aking accurate recommendations for further use.  And for other
ollection materials that may host tougher insects.
I am glad to hear you have had success with freezer trucks- do you
ecommend variations in the length of time in the freezer truck- over
he standard 48 hours currently recommended for chest freezers?

Studies have shown a timber damaged by either powder post beetles or Old House 
Borers loses only 15% of its structural strength.  The reason is the galleries 
are tightly packed with powdered frass.  The larvae are not removing the wood,

Hi


I would apply the spray to susceptible timber throughout the area where the 
borer was active, mainly because their long life cycle within the timber (i.e. 
from when the larvae first emerge from the egg until when the adult emerges 
from an exit hole) means that extensive damage can occur. Sound timber now may 
not be in 3-4 years time.


Best wishes,
Alex

Is the infestation widespread, i.e. frass-filled exit holes throughout the 
structure? We have been quite successful in controlling powder post beetles by 
applying Bora-Care only to the infested areas as identified by holes with frass 
in them and trails of frass extending from the holes, areas such as the sill of 
the building or the base of columns where the wood has a higher moisture 
content and is more inviting. In Vermont, we find that such infestations travel 
very slowly, perhaps because they have been held in check by our cold winters. 
It would be prohibitively expensive to treat all or even many of the structural 
elements of the building as a preventive measure when there was evidence of 
active infestation in only limited portions of the structure.You can always 
apply Bora-Care in the future to additional areas if you detect a spreading 
infestation.

We are in the process of designing treatment for an infestation of wood borers 
in a large historic storage structure. We’re satisfied with all aspects of the 
proposed treatment (Bora-Care application) – however, the pest management 
company has proposed a widespread application, and we’re wondering if the 
application of Bora Care should be confined to just the area in which exit 
holes can currently be seen, or should it extend beyond that?

Hi Derya,
 
Like Patty I am a little daunted at the prospect of checking all of our filters 
(big complicated building).  At a previous institution I worked we did check 
the bottom of the outside air intakes – this only showed what was being drawn 
into the stack (and building). We discussed putting screens on the intakes, but 
I am not sure that happened.  It might have constricted the air flow – the 
discussion took place 10 years ago, so I am a little vague on the results. If 
your filters are in place and your HVAC is in good shape (no unanticipated 
holes in the ducts) the filters should be blocking egress.  If the filters are 
changed on a schedule then there should be little organic matter to become the 
source of an infestation. 
 
Our main problem is with electrical and plumbing traces. This is an old 
building, with a lot of unidentified conduits to be used as insect and rodent 
highways throughout.  There are also plenty of holes in the building.  Using a 
proactive pest management company has made a significant difference in our 
insect levels.  One of the things that the technician does is identify hotspots 
and breeding grounds such as standing water at the bottom of elevator shafts or 
in the attics.  By addressing these issues and keeping in close contact with 
our Facilities staff on the repairs to the building has made a huge difference 
in reduction of pests and in understanding why the pests are present.
 
I sent this discussion to our entomologist and will post his reply.

Hi Derya,
We have been advised to do this, and find it a bit daunting, as well. The 
compelling particulars included finding adult powder-post type critters, who 
fly away as they emerge . Given a large collection of architectural fragments 
inspection is nearly impossible to find new-looking holes. We are skeptical 
that the adults would come across a stumble trap. I don’t think Ryan has found 
a lot of time to do this and our filter-changing schedule covers dozens of 
sites – and is managed by a team that doesn’t have a simple or direct way of 
telling us that dirty filters are ready to look at and then get hauled to the 
dumpster – clearly we don’t have a place to leave them sitting around.
I would love to get an entomologist’s thoughts on this.

Hi Everybody, I was wondering if any of you check your HVAC filters for pests. 
The idea has come up - when our pest control vendor mentioned that insects can 
travel through HVAC systems and get from one part of the museum to another. 
Does checking the filters give us a random sample of what might be around the 
museum? Or is it overkill to look at these? Have any of you actually done this? 
Our facilities staff gave me a used filter to look at today and it is pretty 
large, I couldn't really think of a practical way to check them for insects 
without having it take up a lot of my time.

If indeed this is the Death Watch beetle, Xestobium rufovillosum DeGeer, active 
infestations are extremely rare in the United States.  The larvae attack 
hardwoods, which have been damaged by fungal decay.  In my 36+ year career 
inspecting historic buildings, I've encountered but one active infestation in 
an old barn in Connecticut.  The upper beams of this old post and beam 
structure had water leakage leading to decay and a subsequent Death Watch 
beetle infestation.  Even if you've found such an insect indoors, the 
possibility of reinfestation is remote.

It appears there may have been some sort of fresh vegetable matter at one time in the basket. Some sort of caterpillar fed on the vegetable matter, spun a cocoon, and the moths then emerged. Whatever was the food source was either removed or dried up, hence the end of the "infestation." That's my best guess.

Hello group!





Today, a few of us were looking at some items during a building closing. We came across a basket that had signs of insect activity inside, but couldn’t quite figure out what we were looking at. The weaving on the basket is quite small….about ¼ inch thick. The attached picture was taken on zoom. 





In actual size, the casings you see are approximately 2/3 the size of a typical carpet beetle molting. The casings are also quite sticky, and are attached firmly to the basket material. The frass is widespread throughout a 4-6 inch section of the bottom of the basket. There was no discernible webbing or insect parts nearby.





Any thoughts?





Thanks for your help!

I agree with Lou; it's a clover mite.  They are very common by the millions in 
new and heavily-fertilized lawns.  They feed on a variety of vegetation and 
grasses.  If the lawn touches the foundation, they commonly crawl up the walls 
and enter through AC units and window drip holes at the base of the window 
frame.  Putting a 2 or 3 foot band of dark-colored, crushed stones as a border 
around the perimeter foundation goes a long way towards preventing them from 
crawling up the walls.  The sun heats up the stones and turns the border into 
an effective barrier.

It’s been unusually warm here in the Salt Lake area but not significantly so. 
And most of them were found in our basement traps within collections storage, 
so if they are clover mites, could they be feeding on any ethnographic items? 
Or do these not pose a threat to collections?

A small glueboard is already available from APG (Atlantic Paste and Glue Co., 
Brooklyn, NY).  It is the model number 100-1, Catchmaster Insect Trap and 
Monitor.  As it comes from the factory, the full gluebord, laid out flat, 
measures 7 1/2 x 8 and is perforated to be divided into 3 smaller traps.  The 
smaller traps are to be folded into a tent and can be placed along the 
floorline or can be placed or hung in the collections.  When a small one is 
folded, it measures 2 1/2 long x 2 1/2 deep x 1 1/2 tall.  There is an 
opening in it, which serves as a viewing port.  These are very handy for fabric 
and clothing collections.

Gretchen,
 
Yes, I totally agree, all sticky traps are monitors and should not be used for 
control. They also do not need to be as big as some currently available. This 
is why I am looking at developing a small, discreet little detector with a 
small glue area, which you can place in tight places. It only needs to catch a 
few insects. The monitors will be used to; alert a problem, identify the pest 
or pests and indicate the direction where they may have come from.
 
When it comes to actual methods of control, if the infestation was throughout 
the building I would advocate placing all infected and delicate items into 
ZerO2 FlexiCubes and undertake an anoxic treatment. Whilst that was in progress 
and the collection was safely cocooned  I would use the time to deep clean the 
building and toughly spray with a residual insecticide. At the end of the 
exposure time, the FlexiCubes can be opened and the collection returned to 
display. And then a full IPM program should be instigated.

Colin,

Unfortunately, I do not have access to my linkedin account at this time, but 
will join the conversation as soon as I can.

I agree with Tom - blunder traps are very effective in identifying the species 
that are present in a museum - both pest and non pest species. They are also an 
inexpesive way to start determining population density and distribution. These 
are the first steps that need to be taken with IPM. 

Pheremone traps, when used properly, are good for focusing in on specific 
pests. Pheremones target specific species and not all museum pests have had 
their pheremones specifically distilled. We are not the primary market. In 
addition, pheremones attract only the male of the species.

Blunder traps and pheremone traps are useful tools for monitoring pests only. 
Not for eliminating pests. 

Hope this helps.

Hi Tom 





Our outdoor lighting at the Hunt Museum is sodium vapour, so we’re being very good. Even so, our proximity to the Shannon river results in quite a high number of aquatic flies (mostly Dipterans) that clutter up our blunder traps but are harmless. Thus my interest in the pheromone traps, which would attract only real pests.





However, I note Cindi’s concern that pheromone traps would actually attract pests, so I’m wondering how the proposed traps can avoid this. 





Meanwhile, getting back to lighting, we have a couple of items that might qualify for red. One is a sheela-na-gig who has lost her head and most of her legs, but she still has the important bits.


http://www.irelands-sheelanagigs.org/archive/images/157.jpg





The other is a self-portrait by Robert Fagan with his second wife, Maria. Apparently he was so devastated by the death of his first wife that he waited a whole six months to marry Maria.

Shae -











I might suggest changing your outdoor lighting to sodium vapor fixtures. Most outdoor lighting is mercury vapor or incandescents. The mercury vapor ones give off lots of UV light and attract midges and other flying and crawling insects to the building. This in turn leads to lots of spiders. Of course theleast attractivelight would be a red light, but we all know what that means.

Pat -

I might add - in urban situations, the WCM's are not following people; they're 
following pigeons.  Nesting pigeons are a huge urban source of natural WCM 
infestations.  To a lesser extent, certain dermestids are commonly found in 
smaller bird nests, especially English sparrows.  They are also common in mud 
dauber and wasps with paper nests.

Tom and Gretchen make some good points.
When searching for specific infestations, pheromones are one of the best tools 
out there to focus our attention of where to inspect in large storage areas. It 
always comes down to a visual search, but pheromones can narrow the search to a 
much, much smaller area. 
Sex pheromones are only going to attract the male of the species, not a female 
with eggs or a reproductive pair. If breeding is going on in your storage or 
exhibit space, it was already there before the pheromones were introduced.
Many of the topics at the recent 2011 A Pest Odyssey meeting in London showed 
how pheromones were used in museum settings to monitor and locate infestations 
of webbing clothes moth. The publication of these  topics just came out in 
December of 2011. http://www.pestodyssey.org/publication.php 
If you are worried about drawing in native populations living around the 
museum, you should keep the traps 15 meters away from any door that gets left 
opened on a regular basis. (Although I will say that if you are in this 
situation, you would probably be better off spending your time and resources to 
find a way to exclude outdoor pests with better door sweeps, lighting, screens 
and other exclusion methods. Another good way is to keep the door closed!)
If webbing clothes moth is the insect giving you the most problems, recent 
research has shown that you don't have to worry about drawing them in for 
outdoors if your museum is in a rural setting. Authors; Rudy Plarre and Bianca 
Krüger-Carstensen in their paper titled: “Outdoor trapping and genetical 
characterization of populations of webbing clothes moth Tineola bisselliella 
(Lepidoptera: Tineidae) in the broader area of Berlin” published in  J. Ent. 
Acaral. Res. Ser. II,43(2):129-135, Sept. 2011 showed that outdoor trapping in 
rural areas did not catch any moths, while numbers outdoors in the city were 
relatively high. These moths are clearly following people! 
Research and testing of multiple pheromones being used in single traps has been 
going on for many years and it continues. It often depends on the species you 
are trying to attract as to how well it will work. If you are just starting a 
monitoring program from scratch, I always recommend to first monitor with 
sticky blunder traps, then identify what you find and finally locate the 
source with pheromones only if there is a reliable sex pheromone available for 
that specific insect.

Group -
 
Dave Mueller of Insects Limited can attest to the expensive difficulty of 
isolating specific insect pheromones for particular species.  Unfortunately 
most insect species have one or more pheromones (let's say sex pheromones) 
specific to that particular species.  There's no such thing as a general 
pheromone, which can be synthesized for a range of species.  There might be a 
common bait attractant for, let's say, the more common cockroaches.  Or some 
kind of food attractant for the dermestids.  Perhaps that might be an avenue to 
research.
 
By the way, it is not true pheromone traps will entice insects into a museum.  
Pheromone trap lures do not have extensive reach, i.e. they only cover a 
fairly small square footage of area.  So unless you put a webbing clothes moth 
pheromone trap just inside your dock door and you have a pigeon infestation on 
the roof nearby, such a pheromone trap would not draw WCM's into your 
building.

Whitney and Lou -

In my consulting travels, I've even seen silverfish damage to silk.  They graze 
the surface and finally make their way through the threads.  If a piece is 
displayed against a backing, they will hide behind it and feed from the back to 
the front.  I've also seen quite a bit of damage from ultra-violet light to 
silk.

Thanks, Whitney, that's why I spoke about the natural situation whereby tineid 
caterpillars and dermestid larvae are known to infest.  Infestations from 
natural locations act as reservoirs for potential infestations in collections 
in buildings.

FYI, When silk is processed, the sericin layers on the outside of the fibroin 
strands are usually removed (except in the case of “raw” silk). The process is 
called “degumming.” Fibroin is composed of the amino acids serine, alanine, and 
glycine.

This is a definition of silk from one publication:
Sericin is a hot water-soluble macromolecular globular protein. It represents 
a family of proteins having molecular mass of 10 to 310 kDa. Sericin envelops 
the fibroin fibre with successive sticky layers that help in the formation of 
cocoon. Sericin contributes about 20-30% of the total cocoon weight. The 
sericin protein is made of 18 amino acids most of which have strongly polar 
side groups such as hydroxyl, carboxyl and amino groups.
I'd say that silk is a protein, but is not keratin containing.  Dermestids 
don't feed on silk, but possibly tineid caterpillars are able to?  Yes, it's 
true that both tineid and dermestid larvae will chew on silks as Tom notes, 
especially if there are stains and residues that must be tasty.  In a natural 
situation, in caterpillar silk mats and spider webs or retreats, there can be 
parts of shed skins, dried insect and arachnid corpses (including dried spider 
prey), and the like that would constitute a good diet for foraging dermestid 
and tineid larvae.

Neither dermestids nor clothes moth larvae eat silk.  Silk has no keratin 
(animal protein) in it.  The text books are wrong.  If dermestids or clothes 
moth larvae damage silk, they inadvertently do so as they graze on the sizing.  
Silk threads are so fine, the larvae may damage them, but they are not 
feeding on the silken threads.  They simply chew through them as they forage 
of the sizing.  Wool, horse hair, whale baleen, porcupine quills, embroidery, 
etc. all have keratin and will support fabric pest larval development.

If the larva is that of an Odd Beetle (I have some doubts), then it is a 
potential threat to the collections if they contain silk or wool. It would be 
worth checking any upholstery containing these materials for damage.

The beetles are not a direct threat to collections.  It looks like they are a

Hello all,
 
Yesterday, I discovered a pretty gnarly network of spiderwebs in one of our 
furniture storage areas and, upon cleaning them up, found three dead beetles 
and a live (!) larva. I am fairly new to insect ID and would love a little help 
identifying the bugs. I have attached some (admittedly pretty poor) photos and 
would appreciate any insight you might be able to share. 
 
Thanks very much!

Maria -

The photo of the egg shows the larva or nymph has hatched a long time ago.  If 
you look closely, you'll see the top of the egg alongside the egg shell itself. 
 The larva or nymph has popped the top and is long gone.  It looks alot like 
an Anobium punctatum egg.  Norman Hickin, on page 25 of his book The Woodworm 
Problem, has a good photo of a cluster of Anobium punctatum eggs.  Good luck on 
figuring out what insect laid the egg.

Hello,
 
I am a postgraduate conservaton student from the University of Lincoln 
currently working on this arrow from the Santa Cruz islands of Melanesia. I 
have found tiny (less than 1mm long) slightly elongated, whiteish-transluscent 
egg casings (picture attached) underneath the arrow's barbs and in the joins of 
the bamboo cane. I suspect these may be booklice, but can equally be something 
from the object's province of origin. Can someone advise me? 
 
Many thanks,
Maria

 Hello,
 I am a postgraduate conservation student at the University of Lincoln (UK).
 I have found some insect egg casings on an ethnographic object (arrow from
 Santa Cruz, Melanesia. I am not sure if they are booklice (and should be
 removed), or something from the original province (and therefore should
 stay). I have a picture of one and need some expert advice! Please let me

Forrest -

Neither of those approaches would work.  The only recourse with an infested 
piano is fumigation with Vikane.  Vikane can only be used if someone has a 
chamber or it can be tented in a safe, indoor place if the temperature does not 
fall below 70 degrees F. during the entire fumigation (usually 24 hours).

Hi Tom,  I am interested in your discussion of Nuvan.  A client has a piano 
which has been in the family for quite some time, having been shipped in from 
Colombia.  As you know, drywood termites will often infest individual elements 
of furniture, leaving adjacent materials untouched.  I've wondered about 
tenting the piano and hanging a Nuvan strip inside.  Any thoughts?  I would 
not have considered this approach with any of the old dichlorvos strips.  An 
alternate might be painting the unfinished surfaces of the obviously-infested 
elements of its construction with a borate solution.  Again, thoughts?
 
See you in Reno?

An insect growth regulator will not affect adult moths; it may however affect

Thanks for this post - I was just corrected on a misconception I had between 
the active ingredients of Gentrol and another similar product named Precor, 
which is used for flea sterilization. It had always been my assumption that 
Hydroprene was developed for insects that went through incomplete metamorphosis 
(like bed bugs and cockroaches), and that Methoprene was designed for insects 
that went though complete metamorphosis (like fleas). Since Dermestids, Clothes 
moths, and most other heritage-eaters go through complete metamorphosis, I 
assumed that Precor would be the choice to use if working with an IGR in a 
museum setting. Interestingly enough, there is a 3rd option out called Nylar 
that claims to work for both types of insect growth patterns.

An insect growth regulator will not affect adult moths; it may however affect 
pupation into an adult, sometimes resulting in malformation of the adult and/or 
sterilization.

As far as the use of the IGR’s in the elevator shaft, I agree with Tom that 
they will have limited effect on the juvenile population. A secondary benefit 
of using the product, however, would be the sterilization of at least some of 
the existing adult population. If you suspect there are a significant number of 
adult moths left in the building, the use of IGR’s might be justified. I also 
highly recommend Alpine. I used it in treating yellow jacket nests this year 
(which are historically problematic) and found it to be highly effective. It 
has a great one-two punch, and is non-repellant, which will help contain the 
infestation rather than scattering it.

I think Gentrol would be a waste of chemical.  Gentrol holds larvae in the 
larval state; it usually does not prevent eggs from hatching.  The Alpine Dust 
would be a good choice as long as the elevator pit remains dry.

After tracking and mapping webbing clothes moths for several months, we have 
pinpointed our elevator shaft as a primary source.  It housed a gradual build 
up of debris from eight years of service, which when inspected did contain 
larvae.  We are now looking at having the elevator shaft floor thoroughly 
cleaned and sprayed.  Our facilities provider has suggested using Gentrol, but 
we have only found it referenced with regards to beetles in the literature.  
Any comments on the efficacy of Gentrol for webbing clothes moths would be 
appreciated.  We are also considering using an insecticide/desiccant 
combination – such as PyGanic, or Alpine Dust (two suggested by our facility 
providers).

Vapona strips are something to be very careful of in a museum context (or at

Aleesha -

Spraying around the foundations of buildings for pests should not cause any 
problems to the stored collections.  Making the exterior building envelope as 
tight as possible is critical to preventing ingress from pests.

As for spraying indoors, a professional pest management firm should be 
instructed to use encapsulated or wettable powder formulations, which have no 
odor at all and provide long-term residual.  If these are used, a quarterly 
service would suffice.

Hello all, 

I know that chemical treatment for pests inside of museums is not recommended, 
but what about the spraying of pesticides outside of the buildings? If 
Facilities insists on spraying inside, in areas that do not contain art, what 
is the threshold for how close those spaces can be to galleries? I worry about 
the ventilation system carrying fumes to other places. 

I appreciate any suggestions and input!

Best,

Barbara,
We have used Boracare on timbers in our buildings with great success. It 
initially darkens the wood, but that eventually seems to fade. Sometimes two 
applications are required, but it does halt the infestation. It can only be 
used on unpainted or unvarnished wood. I believe Timbore is a similar product 
from a different company.

Many thanks for all your input.  It is great to have a number of options from 
people who really know what they're talking about.   If anyone could figure out 
how to do the same thing with other facets of life, let me know!   


Given the time it's been inside and the seeming lack of actual insect body 
parts or frass in the collected debris, I'm not doing anything in a hurry.  On 
the other hand, I haven't gone to see it yet, after which  I might change my 
mind.  


The truck (for either freezing or heating) might be a good idea.  The problem 
in New York is finding a place to park the truck!  Sprayed chemicals, even 
benign ones, are a hard sell, because so many people are phobic about 
chemicals.  If various people/organizations hadn't made mis-leading 
statements about the benefits and safety of so many other things for so long, I 
might be critical of this point of view.  Telling someone that a chemical that 
kills bugs is safe in a public space is likely to be a losing proposition, even 
when it's made from flowers!.

If it were webbing clothes moths and newer damage, you'd see silken tubing.  If 
it were case-making clothes moths, you'd see what looks like cocoons and lots 
of frass.  I doubt if you have either.  Neat holes in protein-based materials 
are probably being caused by carpet beetle larvae.  They often hit and run.

Hello – I am seeing some fairly neat holes in our collection of wool docents’ 
cloaks, and some bits of fairly new wool embroidery neatly grazed off some 
linen pockets. No frass, no webbing, and so far no sign of the little fluttery 
critters. Could this be case-making clothes moths? We can freeze, or heat, the 
items, but how do I keep this from spreading to the rest of my collection? How 
do I even tell if these are case-making clothes moths? Are there are pheromone 
traps available for them? The items in qestion are stored on an open rack in an 
office along with a bunch of other costumes, mostly linen and other cellulosic 
fibers, some polyester. No signs of damage there.

Thank you. I guess. We don’t really want to have carpet beetles, either. Any 
suggestions on how to get rid of them in a really porous building with no 
facilities to isolate anything? I think the first step we’ll take is to send 
all these cloaks out to be dry-cleaned, but if the lil boogers have gotten into 
any collections areas, what can I do?

It is NOT a powderpost beetle.  Although you only have the one photo, beetles 
in the family Staphylinidae have elytra (wing covers) which do not cover the 
abdomen - as does your specimen.  At any rate, it obviously wandered into the 
warehouse.  Not a museum pest as far as I can tell.
