It’s an isopod. Commonly called a woodlouse or sowbug (as Todd noted). It’s not 
one that can roll itself into a perfect sphere, but can roll up a little. 
Usually roly-poly refers to those species that can ball up into spheres for 
defense.  It’s from outdoors and come in around doorways, windows, up on walls, 
cracks in foundations, and live under rocks, logs, in leaf litter and mulch, 
etc.
When these die (as in other arthropods as well) they become food for foraging 
dermestid beetle larvae.

Dear Lisa

Looks like an isopod (not an expert, but possibly a rolypoly/woodlouse). Not a 
threat to collections. Unless someone has been moving rotting wood or leaf 
litter through the museum,  it probably came from outside on somone’s shoes.

This was found on a wall in a gallery.  Does anyone have thoughts on its ID?  
Not something we've seen before.

I think the DE powder was probably sprinkled around, possibly an over 
application, and then the boxes sealed.  Do you see powder? It’s slow acting, 
but bed bug and egg dormancy period has passed well before the 10 year mark! 
Any bugs or eggs will have died. DE contains a small amount of crystalline 
silica compared to CimeXa dust where there is none – it’s all amorphous.

Hello everyone,
A curator is considering bringing in an archival collection consisting of paper 
and media materials that was treated for a bed bug infestation with 
diatomaceous earth 10+ years ago.  We don't have much information on how the 
treatment was implemented.  The problems with diatomaceous earth residue on 
collections materials aside, is it an effective means of treatment?  
Information on how long bed bugs and their eggs can remain dormant and how to 
best assess the efficacy of the remediation would also be greatly appreciated.
Many thanks,
Jessica

Merchant grain beetles as opposed to saw-toothed grain beetles are supposed to 
be more attracted to items with a higher oil content such as nuts, copra and 
less to grains.  Adults also will fly as compared to STGB.  Quick listing about 
these species  (Food for Thought, so to speak):
Both saw-toothed and merchant grain beetles are common stored-food product 
pests that infest cereals, cornmeal, cornstarch, popcorn, rice, dried fruits, 
breakfast foods, flour, rolled oats, bran, macaroni, sugar, drugs, spices, 
herbs, candy, dried meats, chocolate, bread, nuts, crackers, raisins, dried dog 
and cat food, and other foodstuffs. These beetles are capable of chewing into 
unopened paper or cardboard boxes, through cellophane, plastic, and foil 
wrapped packages. Once inside, populations build up rapidly often spreading to 
other stored foods and into food debris accumulated in the cupboard corners, 
cracks, and crevices. Sometimes all life stages (egg, larva, pupa, and adult) 
may be found.

Yes. Exactly:  Head, eyes, and temple (space behind eyes to rear of head).  
Actually 3 species in U.S., O. acuminatus in FL from a shipment of neem seeds 
(neem tree has insect repellent and insecticidal properties), but not 
established in 1983. Not sure if this is still correct or not. There are 15 
species world-wide. Typical pest species are the 2 commonly encountered ones, 
O. surinamensis and O. mercator.
BTW see https://www.brooklynbugs.com/ in case you want to do something in NYC 
beginning tomorrow.

Not a powder post beetle. Instead, it is consistent with the merchant grain 
beetle, Oryzaephilus mercator.

Yes and also the ventral view of the beetle that showed the head morphology and 
attachment to thorax did not show dermestid associated characters.

Casey and Matthew -
I think your suggestion that this might be a dermestid is quite reasonable, 
given the compact shape and the presence of scales on the thorax and wing 
cases. However this doesn't match any of the dermestids that I know, and there 
are other families of beetles with scales, notably the weevils and bark beetles 
(Curculionidae). In this case the asymmetric scale pattern gave it away - most 
bark beetles are rather plain, but this genus has a couple of species with such 
a pattern. I used an old book that I've had for over 50 years to make the 
initial identification, and confirmed it with an internet search for images of 
the genus. (There's a limit to what I can keep in my head!) The other clue that 
I had was that Simon mentioned dozens of beetles trying to get out. In my 
experience that most often results from a mass emergence from firewood.

To the untrained eye this looks more dermestid-like, though perhaps I project 
my greatest problem onto any bug.  Tony, as an entomologist I trust your 
observation but wonder about the features that drew you to that diagnosis? I 
was looking at shape and scale pattern (though my amature eye).

Hi Simon
This is one of the bark beetles (Scolytinae) - I would say it is Hylesinus 
fraxini or a close relative. They are usually associated with ash trees 
(Fraxinus), and tunnel under the bark. When they occur in large numbers 
indoors, the first thing to inspect is any firewood. It is most likely they are 
emerging from that. They do not present a threat to the building or its 
contents, except that dead individuals provide food for Anthrenus larvae.
Best wishes

Just a quick ID would be a tineid moth and multiple insects are booklice.  More

Hello all,

I've attached several details of a sticky trap laid in one of our storage rooms 
and would very much appreciate help with identification.

The pest in shots 1 and 2 is the only one of its type on the trap.  Those shown 
in shots 3 and 4 number about 20, which has me concerned.  The storage room, 
unfortunately carpeted, houses mostly work on paper, including books.

Best,

Ben

Hi Megan,
Now that you included a close-up of one insect, it's not a springtail, but a 
booklouse, insect order Psocodea (older literature has it as Psocoptera). No 
termite here.
Either way, it's a moisture issue.

Thanks Louis!

I'm attaching a few more images: I managed to get a shot of one of them, and a 
shot of the mound/nest through the microscope. I'm also attaching an image of 
the pest next to a penny for scale reference; I drew a circle around the pest. 
Looking at it under magnification now I think it does look like a springtail.

One of my Facilities colleagues thought it looked like a dry wood termite 
(we've had infestations before, but not in that part of the house), but this 
seems way too small to be a termite. What do you think?

I removed the mound and, hopefully, most of the pests. The wood underneath the 
mound appeared undamaged, but there is tar paper insulation in the vents under 
the window, so I wonder if that is something they would be attracted to?

Many thanks, your help is very much appreciated!

2 ants. Large one looks like a de-alate queen carpenter ant. Maybe the small 
one is a pavement ant (2-node), but not sure, could be something else. Need a 
better view of it. The moth is a clothes moth (tineid).

Hello everyone,

I found a couple disconcerting pests today. I have my suspicions about what 
they might be, but I'd like confirmation before I decide what actions to take.

Rich,
I agree with the ID as the mite being a species of Balaustium.  I get some 
calls about these mites and also Bryobia.  The default ID by many people and 
PCOs/PMPs is incorrectly clover mites.  They are not aware of other kinds of 
‘red’ mites. There are records of certain Balaustium species biting people, 
too, however the species are not classical parasitic mites (such as those 
blood-feeders known from rodents and birds).  These feeding episodes might not 
be common occurrences.

I’ve been asked by several members of this list for suggestions on digital 
imagers. Rather than replying to each separately, I’ll post here.

I’ve evaluated many such units over the years, and try to keep current on new 
and useful devices. I use several daily in my own work, but I also am an 
authorized reseller for one line of scopes that I frequently recommend to 
clients. ProScope (also known as Bodelin) manufactures diverse lines of digital 
handheld (or mounted) microscopes. They have devices that connect via USB to 
any modern MacOS or Win computer, standalone units that connect wirelessly via 
its own wifi to your phone or tablet, and yet other accessories that clip onto 
your phone or tablet. More recently, they added a digital imager that captures 
excellent images from the ocular tube of a microscope. I use each, and select 
the device depending upon my needs. Find the entire line at 
https://proscopedigital.com.
 You can buy from them or from any other authorized reseller (myself included). 
 Should anyone be interested in my own recommendations and for a quote, contact 
me directly. For examples of images captured using different lenses of a louse 
egg between paper and translucent tape, visit 
https://identify.us.com/idmybug/head-lice/head-lice-images/proscope-lens-compare/proscope-lens-comparison.html.

Finally, back to the mite. That is neither a clover mite nor a biting mite. I 
stand by my initial suggestion, but would be happy to examine the specimen 
directly should it come my way.

The pronotum looks very narrow and wide for it to be a Lyctus species of

Hi Cara,

Unfortunately, that sure does look and sound like a powder post beetle to me 
(though it’s hard for me to be positive without the antennae).

If the altarpiece is on open display, you might want to alert the people who 
clean the gallery that the frass will resemble extremely fine sawdust or even 
very light dirt. It is very easily mistaken for other substances.

Luckily these beetles are pretty weak fliers. If you can’t get the object into 
treatment any time soon, you could be able to partially control their movements 
by using a UV lure in the gallery after hours.

Hi Joel,

Size: 5-6 mm

It was found alive, crawling on a painted platform in front of a painted 
altarpiece on wood panel.  I don’t have any photos of exit holes, but the raw 
wood visible on this altarpiece does have plenty of old signs of pest damage. 
This is a loaned object that reportedly has been treated twice with anoxia in 
the last year, for what type of pest activity I am not sure. (It is typically 
on display in a church, however, so the likelihood of re-infestation seems high 
in that kind of environment.) There was no frass visible below or around the 
altarpiece, however this object is currently installed so I wasn’t able to lift 
it up to examine very closely.

Thanks,
Cara

I have to agree. I've been travelling but the first picture that was posted was 
enough. Very distinctive head.  Some are plant feeders; some predaceous. Their 
wings (if present) are also quite distinctive and characteristic for the order.

Hi Johanna
As others have suggested, a specimen or magnified photo would be best to get a 
definitive name, but looking at your pictures, I am quite sure that the insect 
is a thrips (Thysanoptera). These insects regularly squeeze themselves into 
picture frames (they have evolved to insert themselves into very narrow spaces 
in the plants on which they feed). They will do no damage themselves, but 
occasionally a dead thrips can act as a focal point for mould, which may damage 
works on paper, so they are best removed from the frames.
Best wishes
Tony

Hello Johanna,

Once you have the frame open, you can try using a piece of clear tape to 
capture the insect.  If a standard microscope is not readily available, a 
simple microscope attachment for the smartphone can be obtained for a very 
reasonable price.

Good luck!

Best,

Dear Rich,
attached some more pictures. Have you any ideas?
The insects move, that means they are alive and they are very small (2mm). But 
we will open the pictureframe anyway to get a further view on the problem.

Too bad there isn't a clearer picture of the size of the close-up shot. It 
might be a true bug (something like an aradid), but not a bed bug.  A focused, 
more macro shot would help. Ventral view, too.

Hi all,

One of our volunteers brought this into the museum last week while I was out, 
and said she found it in her couch. Unfortunately, I've only seen the photos, 
as she took it back home since I wasn't here. It does kind of look like a bed 
bug, but seems to lack the point at the end of the abdomen and she said she 
didn't see the distinctive horizontal sectioning you see with bed bugs. Any 
thoughts? I'm curious in case it is a bed bug, but also if it's a pest that 
just looks a lot like one. Apologies that the pictures aren't better.

Thank you!
Robyn

Size doesn't matter in this case (although the longhorned borer -- palo verde 
beetle - is much larger).  If you look at the pronotum, there are no pointed 
lateral extensions which would be on that cerambycid species, Derobrachus 
geminatus.

It seems a little early in the year for it, but, given the size, it looks like 
it could be a Palo Verde beetle. You may want to have your ground crew check in

Hello Again,

First off thank you for your replies to my previous inquiry! We have yet 
another mystery beetle in a different location this time-I have attached 
pictures-according to our security team this guy was found strolling around a 
gallery that has Samurai Armor. He was found on the floor. It is difficult to 
say if he is just one of the many beetles that are becoming more active due to 
rising temperatures as we begin our summer here in Arizona. Any clues would be 
much appreciated.

Thank you!

gallery that has Samurai Armor. He was found on the floor. It is difficult to 
say if he is just one of the many beetles that are becoming more active due to 
rising temperatures as we begin our summer here in Arizona. Any clues would be 
much appreciated.

Thank you!

Many thanks for the link.  One protein source, dried mouse carcasses, shouldn’t 
be overlooked as a reservoir source.  Mouse corpses can be found in “unintended 
areas” if anticoagulant baits have been used, and can also be in “forgotten 
multicapture traps”.
BTW, there have also been instances in North America of a small, but 
differently colored moth (Browndotted Clothes Moth, European House Moth - 
Niditinea fuscella) showing up in the Tineola bisselliella pheromone monitors.  
I saw samples from monitors in people’s homes, but the windows were open and 
there was no damage to textiles; webbing clothes moths not present. There are 
reports of its larvae feeding on dry animal and plant remains.  It’s been taken 
from bird nests feeding on shed feathers and feces, and also associated with 
grains and stored products. A story in Fumigants & Pheromones (2012. V. 104- 
Pat knows this one) by their entomologist (Alain VanRyckeghem, BCE) noted the 
following: woolen rugs in poor conditions such as damp basements may be 
susceptible to attack. They are more commonly found in bird nests – 
particularly of chicken, domestic pigeon, and swallows, where they feed on shed 
feathers and feces. These moths have been found on taxidermy mounts feeding on 
feathers, and in insect cultures feeding on dead bodies and frass. They are 
scavengers of grain or soybean dust in damp dark buildings. The larvae may also 
feed on organic litter in wooded areas, farm buildings such as poultry houses 
or feeding on fungus growth in mulch around homes.

Hi Richard,
The bark (& ambrosia) beetles are now treated as a subfamily, Scolytinae, of 
the weevil family, Curculionidae.  Not sure if the bug is a mirid – I don’t see 
a discernable cuneus in the hemelytra and closed cells also in the membranous 
portion.  Not used to looking at New Zealand fauna.
Fiona, this site might help on that bug is a mirid. 
http://www.landcareresearch.co.nz/science/plants-animals-fungi/animals/invertebrates/systematics/hemiptera/hemiptera-virtual-collection/heteroptera/miridae
You might be able to search through it for more insects.

The first two are adult beetles, most likely bark beetles of the family 
Scolytidae. They resemble Hylastes spp.

The third creature appears to be an adult heteropteran, most likely a member of 
the family Miridae.



The images don't allow for much more precision beyond these conclusions.

Presentation:  "Tick Surveillance, Management Strategies and Personal 
Repellents"
Moses Cucura, an entomologist, is the Tick Specialist for Suffolk County 
Department of Public Works, Division of Vector Control and an appointed member 
to the Suffolk County Tick Control Advisory Committee. He examines existing and 
emerging tick management strategies and products through locally held field 
efficacy trials and provides technical assistance to entities interested in or 
conducting tick management. In addition, he operates a long term tick 
surveillance program with sites across Suffolk County tracking species, 
populations, seasonal activity, and environmental parameters to help improve 
management efforts.

The presentation will briefly review Suffolk County Vector Control's 
county-wide tick surveillance and management initiative. Deer Tick (Ixodes 
scapularis), Lone Star Tick (Amblyomma americanum) and the American Dog Tick 
(Dermacentor variabilis) ecologies will be reviewed and their relationships to 
management strategies highlighted. Individual tick management strategies will 
be examined and the potential synergistic effects of implementing multiple 
strategies simultaneously will be reviewed. Field efficacy of select synthetic 
and various green or organic acaricide products and application methods will be 
examined based on existing literature and Suffolk County Vector Control's field 
efficacy trials. Lastly, tick repellent types and concentrations data will be 
presented and discussed to improve personal protection while outdoors.

RE: [pestlist] please ID pest

[Louis Sorkin]

Yes, from the picture quality it’s a cucujoid and Silvanidae  is a good choice 
and Uleiota dubia or U. debilis, I believe, are the species to compare. The 
specimen would help in its future ID.

I'd second Richards ID, Uleiota sp., but we would need much better images to 
determine further than that and ideally the specimen itself.

Subject: RE: [pestlist] Fruit Fly Question

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.

Are you sure they're fruit flies? I deal with a similar issue earlier this 
summer. We had tons of what I thought were fruit flies in our collections area, 
so I posted a photo of them on this listserv.  By doing that, I was informed 
that they were actually "Black Fungus Gnats," which were an indicator of excess 
moisture in our collections area! Would you be able to post a close-up picture

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

the building and if there is I'd likely notice them bringing in food or other

There are exhaust vents in my work area and in the washroom. The was

RE: [pestlist] Another spider

[Louis Sorkin]

A golden orb weaver is normally thought of as Nephila clavipes, but the spider 
picture (a ventral view) that Ann posted looks more like a species of Argiope, 
probably A. trifasciata. It is known as the banded Argiope. There would be a 
brush on the distal tibiae of legs I, II, IV in Nephila clavipes and these are 
absent in the pictures supplied. There are also remnants of a stabilimentum in 
the picture and that is found in Argiope orb webs.

Hello there,

Can anyone help me to identify this insect? I found it in the main floor 
painting studio and caught it in a cup. My museum is located in central 
Pennsylvania.

The insect is roughly 1 inch long, for an idea of scale. While attempting to 
photograph its abdomen (no luck, sorry), I learned that it does have a set of 
wings, as it unfurled them quite suddenly. They have a slightly purplish 
iridescence. Any suggestions would be greatly appreciated!

Thanks,
Elizabeth

It’s interesting that hydroprene (Gentrol) was developed and tested on 
hemimetabolous insects; Methoprene (Precor) on holometabolous insects (such as 
beetles). Cockroaches and bed bugs are hemimetabolous, but Gentrol basically 
had no effect at label dosages on bed bugs even though the early studies said 
it did.  It has always worked well against cockroaches.  Methoprene was shown 
to be efficacious against certain reduviid (Rhodnius) bugs and bed bugs, both 
hemipterans and both hemimetabolous insects.  These particular IGRs are 
supposed to translocate from original points of application, though I remember 
hearing another word to explain about their movement in the environment.  With 
respect to two related beetles, the cigarette beetle (Lasioderma serricorne) is 
supposed to respond to Methoprene and not Hydroprene, while the drugstore 
beetle (Stegobium paniceum) is supposed to be more responsive to Hydroprene.  
Other stored product pests also respond to Hydroprene.
Insects always surprise us.

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

Group -

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 
good choice for fabric pests or silverfish.

Hello;

This little pest ( about 3mm long in it's mangled state) crawled out of a box 
that came into our reading room from an offsite storage location yesterday. The 
researcher helpfully 'captured' it for us.



Any ideas? Pics are 'front' and 'back' but the pest itself is slightly mangled 
at this point.  Thanks in advance. Katie

Correct. These are very commonly seen as Tom noted. The larvae of most are 
parasitic on arthropods; species of one genus are pollen feeders. Nymphs and 
adults are predaceous.  The pollen feeders have been known to bite people – but 
it’s only tasting, not feeding.  They can actually stay on the roof and walls

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

There are actually many red colored mites and their natural histories differ. 
Bdellids feed on insect and mite eggs and small insects; erythraeids vary 
depending on life stage (arthropod parasites and predaceous); some soil mites 
such as oribatids can be red and feed on decaying plants, fungi, algae, 
springtails; clover mites feed on plants and can be red; some trombiculid 
adults are red and plant feeders, larvae are chiggers and are parasitic on 
various animals such as mammals, birds, reptiles, amphibians, some insects.
Your entomologist relied too much on a generalization.

Correct. These are very commonly seen as Tom noted. The larvae of most are 
parasitic on arthropods; species of one genus are pollen feeders. Nymphs and 
adults are predaceous.  The pollen feeders have been known to bite people – but 
it’s only tasting, not feeding.  They can actually stay on the roof and walls 
of buildings and don’t go back to the ground.  Crushed mites do stain certain 
substrates.

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

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!

[pestlist] RE: identification help please

[Louis Sorkin]

The paler one might be a bit younger than the darker one and hasn’t yet tanned 
and darkened. These look like members of the Latridiidae and probably belong to 
a species of Corticarina or Corticaria, possibly leaning toward a member of the 
first genus.  Vental views and tarsal views would help, but the latter might be 
difficult to provide.

From the picture, I think you found Pyralis farinalis. The meal moth. You can 
look up info on it.  From one site:
* Is a minor pest of coarsely ground cereal products
* Wheat, barley, oats, corn, peas, beans, flour, peanuts, dried fruit, 
potatoes in storage, mixed feed, processed cereals, hay (alfalfa and clover)
* Is most abundant in mouldy grain, decaying cereals and cereal 
products that have a high moisture content
* May be thought of as an indicator of poor sanitation

Nancy  others,
Actually, I'm putting together a presentation for pest management professionals 
in November (there's a recertification meeting that time every year in NYC) and 
my topic this time will be something like W** is stuck in the damn glue? 
(title to be amended!).  This way the PMPs will have some help in identifying 
the unknowns by their parts because many samples are not in pristine condition 
after capture.  I've been amassing quite a number of glue boards over the 
years.  If you have any good ones -and don't mind parting with them- please 
send them along.  This can be a beginning for some type of publication.

Thank you Rachael,

And, you are right, it is interesting to see the photos come in and certainly, 
when specimens are stuck in the glue on insect monitors, they do not look like

Dear Colleagues,
The PestList is an amazing resource that has grown from its original 11 users 
to over 600 individuals worldwide.  It is gratifying that entomologists, pest 
management professionals and others are available to share their knowledge and 
identify pests that we find in our institutions.  I'd like to remind everyone 
that there resources on identification developed by the IPM Working Group on 
the MuseumPests website http://museumpests.net/identification/ .  Before you 
post to the list please take a moment to check the image library, the Pest Fact 
Sheets and the section with additional Identification Resources.  I don't want 
to discourage people from posting to the list, but you may find that you can 
answer your own question and learn an additional useful fact or two as well!

We also wanted to let you know that virtually all the presentations and posters 
from March's MuseumPests 2014: Integrated Pest Management for Museums, 
Libraries, Archives and Historic Sites conference and workshop session are now 
online at http://museumpests.net/museumpests-2014-conference/.  We hope that 
you will take some time to peruse this new, valuable content.  Again our 
grateful thanks go to my IPM-WG Co-Chair Ryan Jones, Patty Silence and the 
Preventive Care and Conference staff at the Colonial Williamsburg Foundation 
for managing and hosting the program.

We have other new content that was completed at the meeting and will be going 
up in the next few weeks.  Please check the website and we'll notify the list 
as we go.

Best,
Rachael

Vapona (Dichlorvos) is under a different formulation than it was years ago. 
Produced now as Nuvan strip made by AMVAC. Also as Hot Shot No Pest Strip. It's 
not registered in Canada.  It's an organophosphate insecticide, a 
cholinesterase inhibitor action material. Atropine is the antidote. Different 
ones are formulated for professional use and some for general public use.  I 
think it's a big problem in letting the public use it; they really don't read 
the instructions that well.  I really don't know if I'd include it as a product 
for your book, unless of course, you are also including other insecticides and 
pros and cons.

I am working on the pest control chapter of my next book.

Question:  I have a note to myself from the March meeting about increasing moth 
problems and the usefulness of Vapona. Should I be recommending this?

Hello everyone,

We're pretty certain the larvae we found in two sticky traps are those of the 
Odd Beetle.  But, just to confirm, take a look at the attached photo and let me 
know what you think.  I believe we have been finding them over the years but 
they have been misidentified.  With a refreshed IPM program we're doing a 
better job of ID, documentation and monitoring.  :)

For some context:
- The museum is in Northern Delaware
- The traps were both in closets - one on the 8th floor (only one more floor 
above it) and the other on the 1st floor
- Neither closet houses material Odd beetles are known to feed on - fur, 
feather, hide

I'm suspect of what in our walls, roof, voids etc.  The 8th could have the 
remains of bird nests outside.  The 1st floor is a bigger mystery.

Thanks,

The beetle looks like a minute brown scavenger beetle family Latridiidae, genus

Genus name would be spelled Melanophthalma, but see my previous post on another 
genus.

John,
I have identified these at CMNH  - so we definitely have them in the museum 
system here in Pittsburgh. I had John Rawlins identify them - they are 
difficult to ID to a species level. Do you have moisture in the area of the 
traps?  Let me know if you want me to swing by and take a look.

Greetings pestlisters,

We caught this small beetle, Trap#5022-1a, in a sticky trap on 4/30/2014  in 
Pittsburgh PA.
It measures a little more than 1.5 mm long.
It seems to have 9 or so small ridges along each side of its thorax.

We also caught this small larva, Trap#5033-3b, in the same area.
It measures less than 1.5 mm long.
It was alive when captured.

Any ideas?  Latridiidae maybe?
Thanks!

Looks like a weevil, family Curculionidae. Could be a species of Otiorhynchus.

They're small creatures anyway and some have actually been taken from drier 
habitats.  Possibly too much dampness, as you noted, is making them more 
visible as they try to leave very wet places.  Carpet beetles (larvae) could 
munch on dead bodies of bristle millipedes.

Thank you for all the responses. Consensus is that it is a Bristle Millipede 
larva. Thanks to your explanations, I believe I can now see the legs on the 
underside, which number far more than the three pairs that an insect would 
have. While these guys like damp conditions, I think our recent rains made it 
too damp and they came inside for refuge from the large puddle of standing 
water outside the building. You can imagine my relief that we are not being 
invaded by carpet beetles!

I would appreciate help with a more definite ID on this insect - I have seen it 
incidentally in traps before, but have been seeing it in higher concentration.  
I have identified it from reference books as a springtail and nuisance - am I 
on track?  The second image contains a CM ruler with MM marks for scale.

Thanks,

I'd say it doesn't look like Periplaneta americana (8 eggs on each side, 14-16 
eggs total and case not as long as next 2 species), but looks most like Blatta 
orientalis (16 eggs), the oriental cockroach. Another possible species would be 
the smoky brown (Periplaneta fuliginosa) with around 24 eggs/capsule.  American 
cockroach ootheca is not as long as other two.  Difficult to see the side 
sculpturing of ootheca to see eggs/side.

Hello,

I don't believe the samples are larder beetles, since they tend to burrow into 
wood to pupate.  The pupal cases are probably left in the wood when adults 
emerge.   If there are holes in the frames, then may be it is larder beetles.

Now that I've looked at the picture closer, they look like American cockroach 
egg cases.

Justin

I think the mass is not secreted by crickets (Gryllus bimaculatus).
No, not secreted, but the parasitic worms emerged from the host cricket.

I think the mass is not secreted by crickets (Gryllus bimaculatus).

Hello all,

A colleague of mine in Kansas forwarded me the attached image of a sticky trap 
and is requesting some help in figuring out what the mass of light yellow, 
squiggly material might be. Is it something that was secreted by the crickets 
on the trap or something completely different? Thanks for your help.

Actually I'd go along with Nematomorph worms (gordiids or horsehair worms as 
Tom mentioned) rather than nematodes.  Maybe the genus Paragordius since these 
are known from crickets.

Angela,
Those are most likely nematodes exiting the bodies of the dead crickets.  When 
we did sticky trapping across the street from you at the Natural History 
Museum, we found those in the traps fairly often.

Not a beetle (order Coleoptera), but a true bug (order Hemiptera).  It's dusty,

Group -

As Lou Sorkin has correctly stated, it is a larva and perhaps another photo of 
a shed exoskeleton of the Odd Beetle.  It is impossible to determine the sex of 
this larva from a photograph.  Yes, it is in the family Dermestidae.  The adult 
male and female look dramatically different from one another.  These photos are 
not of an adult Odd Beetle.

Well, there’s a slight chance I’m wrong as I can’t say I know all the 
Dermestidae family, but it looks like the shed of a varied carpet beetle larva

Greetings. I have been finding some dead insects in a very large donation of 
gift books. Here are some photos. They are very tiny, maybe 1/16 of an inch.
They are all dead but I am still concerned that they could have left eggs, do 
not have the $ to treat the huge collection but am under pressure to add it for 
political reasons. Do not want to infect our collections though!

Please identify and advise.I really appreciate your help and advise, if only 
dead bugs and nothing live is found how safe is it to add?

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!

Another reason to change to LEDs, for outdoor nighttime use in particular:  No 
ultraviolet, so no insect attractant.  Many companies make LEDs for this 
purpose, which has nothing to do with museum per se.

Matthew -

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.

Group,

In was presented with the attached specimen this morning. To me it looks like 
either Magatoma variegate or Anthrenus museorum. Any thoughts on its ID?

Thanks,

I'll have to look up species, but at least you should know that it is a 
booklouse, and one with wings; not the common liposcelid with enlarged hind 
femora that is commonly encountered.

Hi All,
I was hoping someone might be able to help in identifying the insect in the 
attached images.  There were two of these (both in unfortunately awkward 
positions) caught on a blunder trap in a corner next to a pipe passing up 
through the floor and along the wall.  This space has high humidity, with known 
populations of silverfish and psocids. Any information would be appreciated!

Thanks,

Hi there,



I think it might be Dorypteryx domestica, a type of cave barklice related to 
booklice. I used to find them in the museum where I worked, usually in damp 
places along with plaster beetles and booklice.

Good afternoon folks,

I'm posting this image and request for assistance on behalf of one of our 
community partners.

The specimen was located within a collection of works on paper within a 
solander box. 5 bugs in total were captured.

Can anyone identify the species?

Thanking you in advance,

Looks like the brown marmorated stink bug, Halyomorha halys.  The front leading 
edge of pronotum should be smooth and not wavy or toothy.  Other characters 
look good.

Not a direct threat unless it gets squished on textiles, paper, photographs, 
etc.  True bugs produce repugnatorial chemicals and these, I suppose could 
stain surfaces.  Squished body introduces more compounds into the material.  
Dead ones form food source for dermestid beetles.  The bugs enter buildings in 
order to spend the winter but on warmer winter days become active and fly about 
exhausting their stored energy reserves and die sooner.

What's the risk with this type of stinkbug for a collection and exhibitions

Not an insect, but house centipede with many legs missing.  Front is on left -- 
long antennae and toxicognaths (modified front legs for venom injection).

Amber,
Yes, looks like one of the Oecobius.  Would like specimens anyway so we 
actually would have a record of occurrence.  You could keep live ones as pets; 
they don't take up much room.  It would be interesting to know what they are 
eating since many records list ants as a preferred food item.
Don't know if anything is actually attracting them; the population is already 
in the building.  Maybe local conditions moving them away from the normal areas 
in which they live.  You are basically finding large ones, adults and not 
very small spiderlings.  Although maybe spiderlings are not around this time of 
year.  Maybe you're not seeing webs because the spiders are leaving webs and 
crawling about, at least, the males would do this.
Lou

Hi Louis,

Thanks for the info - I'm sending better photos with a ruler for scale.  The 
spiders are less than 1/16th of an inch long.  We have not seen any webs yet.  
The areas we've found them in don't have windows, so I'm not sure where to 
look, but it's possible we are vacuuming them up before we get a chance to see 
them.  If you'd really like me to send you one I can, but they are all stuck on 
sticky traps so I'm not sure how well they will travel.

Generally spiders don't trouble me, but this increase in tiny spider population 
makes me wonder if there is something else going on that is attracting them.

Thanks,
Amber

That's a male. You can tell by the modified, enlarged palpi.
It is a member of the family Oecobiidae. Most likely, depending on where you 
live, either
 Oecobius navus Blackwall, 1859Cosmopolitan or
Oecobius cellariorum (Dugès, 1836) *Cosmopolitan
The species are quite common indoors, often in a distinctive kind of web near 
window frames. Web consists of 2 thin, silken sheets connected by some silk 
lines radiating from the sheets to act as trip lines.  The spider lives between 
the two sheets, residing on the lower one.  Webs can be along window frames, 
ceilings, walls, floors, sort of edges where structures come together. The 
common name is flatmesh weavers.  Has a cribellum (in front of spinnerets) and 
anal tubercle with a brush of special bristles that aid in spreading the silk 
from the posterior spinnerets as it encircles prey. It has a distinctive shape 
to its body and leg

Hello List,

We've seen a few of these tiny spiders on our sticky traps.  We find them in an 
area that tends to have higher humidity and a (slowly decreasing) population of 
psocids.  We'd like to find out more info about this spider - if it's 
specifically drawn to humidity or psocids, or if it's an indication of some 
other, as-of-yet-undiscovered issue.

Thanks!
Amber

Actually brown-banded cockroaches are common in New York City, but that wasn't

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?

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 Mr. Tom Parker,

Thanks for your suggestion. The building is at least a decade old. I think 
giving a post construction termite prevention treatment using Imidacloprid 
30.5%SC will be good. I would like to know the physical requirement for the 
newspaper archiuve building. Hope to receive some more information from you.

Regards.

The newspaper photograph shows very old damage originally caused by 
subterranean termites.  It is not active.  The areas on the face of the 
newspaper shows where termite tubing once was, but has since been brushed away.

Dear All,
A big News paper record has been shifted to new building. We inspected it there 
is no termite or any other infestaion at the new building. The newspaer archive 
has been attached by some insects. The sides of the newspaper is damaged or may 
be eated by some insects. May be it is damaged by termite  or any other insect 
has damage papers. What preventive precautions should be taken for the safety 
of the record.

Any guidance will be appreciated.

Regards.

“Most insecticides fail because the spiders do not actually come in contact 
with them.“
Actually I think the information about spiders has been repeated but is not 
really true.  Most PMPs and others have the idea that spiders must be walking 
on their claws akin to ballerinas dancing (walking on tiptoes) and this is not 
so.  There are those spiders that crawl on 3 claws and those that crawl on 2 
claws, with many of the latter also having tarsal pads or claw tufts.  Also 
people believe that (adult, specifically) bed bugs cannot climb smooth, 
vertical surfaces because there are no tarsal pads compared to American roaches 
that have such pads and are known to walk on many surfaces including smooth, 
vertical ones.  This is incorrect, too, since pest bed bugs have special leg 
adaptations to do so.  A reason might be that the spiders do not stay for a 
long period of time on a treated surface or the material really doesn’t have a 
long residual life or that the applications aren’t really in areas where the 
spiders stay.  Certain insecticides don’t work well against spiders although 
direct hit usually works.  Dusts will adhere better on their bodies as compared 
to liquid preparations.
There must be space by which prey items and spiders gain access into the 
structure.  Recluse spiders are also long lived (living a few years, not annual 
species) and the populations may have built up over time and are not from very 
recent introductions.  The population may be centered in the lower levels or 
basement area and crawl around to the upper levels. I’ve seen this in a NYC 
apartment building.
We have a spider exhibit running through Dec. 2.

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.

I have been monitering our museum using sticky traps spread every 10 feet 
throughout. A significant number of brown recluse spiders were caught, seventy 
in a two month period of time. Fishing for suggestions on other ways to control 
them besides sticky traps. I gather insecticides are largely ineffective.

But I guess if she reads your email……

Proper building maintenance is essential.  I’ve included the information from 
the published article regarding the house construction. Maybe the Oklahoma 
building has something similar in regard to construction/layout.  No mention of 
a basement in the first study home ( 3rd).

Study home:
The house was originally constructed in the 1850s of
45-cm-thick exterior limestone walls and consists of
three floors encompassing 270 m2 of living space. Attic
space adjoins east and west second floor walls with
another attic above, all with floors covered with 8 cm
of blown insulation. The roof has original wood shingles
covered by three layers of asphalt shingles. House
additions were made during the 1920s and in the
1960  1970s; the first addition enclosed an exterior
wall. Interior stone walls are covered with plaster.
There are several outbuildings, including a horse
barn, chicken coop, garage, and open-sided hay barn.

2nd home:
The first is in Des Peres, MO, 17 km west of St.
Louis. This 158-m2 home was built in 1946 of brick on
poured concrete foundation construction. The home
consists of two floors plus a 93-m2 finished, concrete
floor basement and attached garage.

3rd home:
Her 167-m2 home is situated on a 1-ha property
and was built in 1963 on poured concrete foundation
with one floor and no basement but with a storm
shelter connected to the back porch and a barn with
one horse.

The Barger home is well over 100 years old -- I think close to 150.  It is 
solid brick.  Local legend has it that it was the home of Wild Bill Hickok when 
he was town marshall of DeSoto, KS.  My home was built in 1976 and is typical 
of current building, with wood siding and a couple of stone veneer walls.  I 
keep and monitor sticky traps in the basement and, due my efforts toward 
exclusion, I have few insects or spiders in the home - a very occasional brown 
recluse.  My wife doesn't know about those.

Hi Forrest,
I figured you knew about this home.  Your home is different construction and 
vintage?  Your neighbor’s home supports a large Loxosceles population but yours 
does not.
Yes, I know you didn’t mention the tippy toe aspect but that’s normally what 
people think about spider tarsi and certain insect tarsi as well.  The 
inference is there and it is usually one reason the manufacturers give for 
their products not working.  But as we know, the product has to be placed in 
the right place to be effective.

Lou, Please note that I did not say anything about walking on tippy toes, 
although I guess that could have been inferred.  In truth, most PMPs don't put 
pesticides where they are needed most - behind, beneath, within. And, yes, 
direct hit works best and dusts are better than liquid sprays.

Elin -

Heat treatment for stored product pests 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's germination rates or its 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). Is there anyone with experience of heat treatment in large 
areas or maybe has any documentation? We are mostly concerned about the effect 
on DNA.

Thanks for any information

Stephanie -

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.

I'm hoping that some of you can help with advice on bed bugs and treatments for

library materials.



We have had three separate incidents of books (all hardcovers) returned to the

Libraries with bed bugs hiding in the spine hollow.  In one instance, there were

at least five live bed bugs in the affected book, along with an egg on the

headband, and staining on the textblock near the spine hollow.



One time the affected books were bagged and a pest control company inserted a

NUVAN strip for two weeks:

http://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

allow the materials to off-gas for 2-6 hours.  Given this treatment, would it be

safe to return these to the circulating collection for use and to have our

conservation 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

days out, and are planning another 7 days in the freezer.  Would you recommend a

shorter cycle/combo for a -20 freezer?  And if we used a 0 freezer, what cycle

would you recommend?



While we know that the bed bugs won't damage books per se, we want to make sure

that they don't find a home in our facilities over time.



Thanks for your help!

Stephanie

Freezing is the easiest since you're not in the forests, deserts, miles away 
from civilization, but in your home or office.  I think ethyl acetate would be 
the material used in the killing jars - less dangerous than acetone.  Ethanol 
is good as a fluid preservative and killing agent.  70-75% is good and 95% good 
for DNA preservation but specimen becomes brittle.  Propylene glycol is also 
good but kind of slimy.  Good preservation of DNA and you can mail specimens 
and not have to list the material as dangerous goods because not flammable.  
Sometimes letting an insect starve may ruin the specimen if tissues decompose 
prematurely prior to preservation or photography.  Dragonflies and damselflies 
are good candidates for the starvation route because their gut gets cleared out 
and the body coloration remains pristine.

Barbara,

The kill jars that entomologists use before pinning an insect in a collection 
use a small volume of acetone to quickly kill them. The easiest source for 
cheap acetone is fingernail polish remover, which works fine. Pour a bit over a 
paper towel  (don't soak) in the bottom of a container and you are ready to go. 
Freezing can also work.

Subject: [pestlist] killing bugs and leaving a beautiful corpse

I am trying to get an intact dead body of a particular type of insect to 
photograph so I can have it identified, but it takes a long time for them to 
die by starvation after I put them in a jar.  I noticed that a squirt of Windex 
incapacitates them temporarily but does not kill them, so I dropped a small bit 
of cotton wet with full-strength ammonium hydroxide into the jar with a 
recently caught one, and it died quite quickly.  I am not, however, looking 
forward to opening the jar.

Is there some other common but deadly substance (other than RAID) that would 
make a quick kill?

Based on my Windex experience, I suggest it when you are trying to catch 
insects without squashing them.  It may work on flying ones as well as crawling 
ones.

Hello,

We have found several of these small insects in different traps located in our

We would really appreciate some help in identifying them.

Thank you everyone for the responses.  I peeled back the plastic that I had 
over the sticky trap in order to get some better pictures and possibly found an 
adult.  To my uneducated eye, the adult looks like Cleridae in shape but not 
coloration.  If it is a Cleridae of some sort, how alarmed should I be?

It's a beetle larva, and doesn't appear to be a dermestid, but I'd hesitate to 
go beyond that.
A couple of possibilities are Cryptophagidae or a young Cleridae, but I think 
you'd need to show a specimen to a coleopterist to be sure.

Yes, looks like a female chironomid.  There have been reports of inhalant 
allergies affecting people due to large mass adult emergences.  Over a few 
years there have been a different kind of fly (a chaoborid midge) that had mass 
emergences off 5th Avenue near the Met  Guggenheim museums.  Many people in 
certain affected apartments also experienced inhalant problems when these 
adults flies were all over their windows/screens.  Chaoborid larvae are aquatic 
and feed on certain mosquito larvae.  It's possible that the midges were 
breeding in street rain drains where certain mosquitoes (possibly Culex pipiens 
molestus) also breed.

Hi Kate
Your picture is of a female non-biting midge (Chironomidae) - they are often 
abundant near water, where the larvae live, and swarms of males can sometimes 
be a nuisance. They don't pose a threat to the building or contents, but can be 
annoying for visitors (and staff!).

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

This staphylinid could be a male because it has modified front tarsi.  Some

Hello,

Now that we know the list is working again, I have an identification question. 
I believe the attached photos are of an adult male odd beetle and an odd beetle 
larva, but would appreciate a more experienced opinion.

Thank you,

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.

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.

Just pointing out that they are very different from the typical insects 
associated with cultural collections
“Bed bugs and their eggs cannot withstand -20 F for 72 hours; not that bed bugs

“It is true about bed bugs; they're tough critters.  However, there's no way

0°F is effective in killing bed bugs, but items must be left in the freezer for

I know this particular email from Tom Strang concerns freezer trucks.  He's 
right on with what I've been saying all along; you don't have to reach -20 F in 
4 hours.

Let me address chest-type freezers.  There seems to be confusion out there 
about them.  There are lots of chest-type freezers available today that can 
maintain -20 F.  And frost-free freezers are OK.  Do an on-line search and 
you'll see what I'm saying.

Dear Dana,



You should not be disappointed with your low temperature  treatment.

I assume a record box is roughly 16 inches long, 12 inches wide and 10

inches high. Your email indicates they were stacked as walls. I assume they

were stacked sides-abutting to make them more stable leaving a wall 16

inches thick.  With close packed organic, akin to bales of agricultural

product, your stack will have a  time to thermal half change in about one

day+.  72F degrees is 21C. -15 F is -26C, more than adequate to kill pest

insects so not achieving -20F (-28C) is not a concern as -20C is quite

sufficient for a week. The fact you achieved -26C from 21C means you

dropped 47C in 4 days,  about a time to half change of a day (remember the

frog jumping half down a log, then half again.. when does the frog jump off

the log puzzle). Were you at 5F at two days? if so you were pretty much

spot on what can be estimated from the chart I published in 1994, and is

available in the  CCI TB29 and on our website (find ten agents  pests).

Hold them at your -15F setpoint and you will have had an efficacious

treatment unless there was thermal bridging from the bottom of the van into

the base of the stack. If they were on pallets, and air circulated under,

all should be well.

Sincerely,

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.

First of all, the temperature does not have to reach -20F in 4 hours.  It 
should reach 32F in 4 hours.  That's sufficient.  The reason you use a truck 
capable of maintaining -20F, is it will reach the desired 32F in 4 hours.  Once 
the liquid in adults, larvae, and eggs reaches a freezing temperature, ice 
particles form and destroy the cellular structure of the living organisms.  
Unless you're dealing with book worms, which I doubt you are with archival 
records, any insects found in these materials will certainly be killed.  When 
freezing anything, you're trying to beat insects from forming natural defenses 
to freezing.  I think your process worked fine.  Have you found any live 
insects?

I have had plenty of sucessful freezing episodes with freezer trucks, 
containers, and warehouses.

We recently tried using a freezer truck to process a large number of
boxes of archives.  Record boxes were stacked in rows with 12 gaps
between the rows to allow for air circulation.  We placed a datalogger
in the center of one of the boxes of archive materials (in the center
of the truck) and another outside the boxes to measure the temperature
of the air in the truck box.  The results were surprising.

We had been informed that the truck would go down to -20 degrees F in
4 hours.  Our data loggers showed that it took 10 hours for the air in
the truck to go from 44 degrees F to -15 degrees F, and the
temperature inside one of the record boxes took ~96 hours to drop from
70 degrees to -15 degrees.  (The boxes had been in a 72 degree
environment before being placed in the truck box).  It appears that
the starting temperature of the boxes of paper was more difficult to
reduce than I expected.  And the truck never achieved the desired
temperature.

We are very disappointed in these initial results and are trying to
figure out if there is a different  strategy for using a freezer
truck, or if this is just not feasible for freezing densely packed
materials, such as paper packed in a record box.  We are discussing
packing boxes half full and packing the truck to allow for even more
air circulation.  But it seems that getting to the goal of -20 degrees
F in 4 hours may not be feasible.

Tom,
Did you ever see any prey items that the wasps carry?  Maybe these are
some species of sphecid wasp?
Lou



 Lou -

 The wasps I've observed kick out the frass and use it as a nesting site.
 When she's finished, she plugs the  hole with mud.  I've seen it with
 small, round holes on the exterior of log cabins as well as Old House
 Borer oval flight holes.  There are a variety of wasps involved.  I've
 watched the females in certain situations, but have never collected any.

 the beetle frass.  Also, some small wasps can be parasitoids of wood
 boring beetles.

 Group -

 Questions concerning powderpost beetles have recently arisen.  Over the
 past 35 years, I have provided expert witness testimony as an entomologist
 specializing in urban pest management in hundreds of wood-destroying
 litigation matters in numerous states.  I am attaching a summary of
 information about powderpost beetles for your review.  Feel free to ask
 questions about your specific situations.

 Bethylid Wasps (Bethylidae)

 These are small to medium-sized, usually metallic-bronze wasps. Either or
 both sexes of a species may include winged and winglessm individuals. The
 larvae are commonly endo- or ectoparasitic on the paralyzed or dead larvae
 of beetles, moths, and butterflies.

 In 1927, a tiny black wasp of the genus Epyris, which inflicts a severe
 sting, was reported from Yolo County, California (von Geldern, 1927).
 These
 wasps were said to appear in large numbers in the fall after a warm spell,
 invade houses, and get into bedding and clothing, where they stung when
 crushed against the skin. Individuals within a family varied greatly in
 their reactions, the most sensitive suffering general systemic disorders
 over a period of about a half hour, including itching, cramps, diarrhea,
 marked prostration, weakness, and sweating. The wasp was Iater identified
 as
 Epyris californicus (Ashmead). It is occasionally reported to sting people
 in the lowland delta area in northern California. It is believed to
 parasitize the larvae of tenebrionid beetles (Essig, 1932, 1942).
 Muesebeck
 et al. (1951) recorded the species as occurring in California and Arizona.

So far have never had any reports of these reactions to a few cases that I
have come across.



 Cephalonomia gallicola (Ashmead) occurs in the eastern United States,
 Europe, and Asia, and is probably cosmopolitan. Certain beetles, such as
 Stegobium paniceum and Lasioderma serricorne, which commonly infest stored
 products in the household, are hosts of this wasp. Adult wasps are likely
 to
 become abundant in houses with a persistent infestation of the beetles,
 and
 there have been many reports of the human occupants being stung. Other
 bethylid wasps of the genus Sclerodermus parasitize cerambycid beetle
 larvae
 infesting the woodwork of houses, and the adult wasps have often been
 reported to sting people (Muesebeck et al., 1951).

 http://www.insects.ucr.edu/ebeling/ebel9-2.html

Yes, I've come across a few instances of Cephalonomia in NYC that had been
stinging and, of course, people thinking it was bed bug infestations.  Had
them use a roll of lint remover tape to collect from the surface of the
couch and walls after looking at the specimens of what had been collected
and identified as ants by their pest control person.  Baits systems
didn't work (obviously).  Had them look for stored product pests and one
person (who was an herbalist and had imported dried Chrysanthemum plants
from China) located lots of Lasioderma serricorne (cigarette beetles) in
the packaged plants and also male and female wasps (males are winged). 
She brought the package over to me.  She also didn't have bed bugs.  Also
had another case (different bethylid) due to a wood boring beetle problem.
 There have been dermatitis reports over the years in Japan due to
Cephalonomia stinging.

If identification is correct, could there be a stored cache of food by
rodents and that's what's infested?



 Hello all,

 My name is Ryan Jones, and I am the IPM Specialist for the Colonial
 Williamsburg Foundation in Williamsburg, VA.

 We have recently encountered a problem in one of our museums that we would
 like to get your input on.

 Approximately two months ago, we had a section of wood flooring torn out
 near one of the galleries in the DeWitt Wallace Art Museum. Around that
 time, we began to see large numbers of small, unidentified red beetles
 that were roughly 1/8 inch long in an office that was 150-200 feet away
 from the work-site. We sent these beetles off to a nearby university to be
 identified, and, to our surprise, the specimens were identified as Square
 Necked Grain Beetles. As you know, Square Necked Grain Beetles are a
 stored product pest that would likely be right at home inside  a container
 of corn meal, flour, or other food product. We have been puzzled, however,
 about how they could live in such large numbers in an art museum.

  I have researched these insects online and have found no evidence that
 they would be able to survive in a subfloor or wall void without a food
 substance to sustain them. We have inspected the surrounding workshops
 and mechanical rooms, break room, and other areas that might play host to
 an infestation of these insects, but have had no luck finding a source.
 The beetles continue to be found in some of our textile displays, on the
 wood floor beside the baseboards in sporadic areas throughout the museum,
 in hallways adjacent to the gallery, and in large numbers in the office
 where they were originally spotted.

 What are your thoughts on how we can get rid of these pests?

 Can Square Necked Grain Beetles thrive in an art gallery, or is there a
 possibility that the insect was misidentified?

 Is it possible that these beetles can invade from outside? (One of the
 common denominators seems to be that the sightings occur in close
 proximity to an exterior wall.)

 I am prepared to take pictures of the insects or send samples if need be
 to clarify what we are dealing with. I have reviewed pictures of this
 beetle online and the specimens look exactly like the ones we are seeing.

 Any help with this would be greatly appreciated.

 Thanks,

 Ryan Jones

 In reference to the first post, most recent research states that:
 118dF for 20 minutes kills adults and 49 minutes at that temperature for
 eggs. At 122dF eggs killed almost right away- adults and nymphs obviously
 also die.
 Packtite is a heating system that will get up to 140dF or more. It is a
 portable system basically designed at first for luggage. There is a rigid
 metal wire shelf base on legs. Heater mounted beneath. Timer plug from
 1/2 hour to 8 hours and comes with a temperature probe (you can add as
 many as you like) to inform you about the temp at a certain location
 within the material you are heating.

 Freezing is an option, too, although keeping them at -30dF for a few hours
 didn't do much and they woke up after thawing. A longer period of a few
 days will work as will freezing, thawing, freezing.

 I've worked on one project where thousands of books were argon
 treated/anoxic treatment. Also in commercial ventures and Vikane
 (sulfuryl fluoride) was used. Spot heat treating in a box composed of
 insulation board (8'x8'x4') and also heat treating homes, apartments, etc.

 I am supposed to be speaking at the upcoming Museumpests.net Integrated
 Pest
 Management Working Group, (IPM-WG) and am preparing a page on bed bugs for
 the museumpests.org site.


 Colleagues,

 I am trying to work on a procedure for treating bound paper materials
 that have bedbugs. We haven't had any confirmed sightings yet in
 materials, but considering our State-wide problem I fear it is just a
 matter of time. I've seen plenty of good information related to
 facilities, but not a lot related to caring for books that have been
 affected. The most common quick quip is that they should be cooked at
 temperatures around 140 degrees Fahrenheit for 2 hours. I've not seen any
 indication what they are being cooked in. There is a device called
 Packtite that gets some mention on blogs, but not on any
 conservation/preservation sites. NEDCC, LOC, and Lyrasis sites don't
 have anything yet either. From what I've read freezing apparently doesn't
 kill the egg stage. My concern right now is the general
 circulating collection, so freezing might be the only option for
 rare/unique materials



 Has your institution started tackling this question? Any help would
 be
 appreciated!

Regarding the species, I wonder if anyone noticed any sound production by
the beetle before finding them dead?

Volume 87 Issue 1-4, Pages 417 - 429
The ash bark beetles Leperisinus fraxini and Hylesinus oleiperda:
stridulatory organs, acoustic signals, and pheromone production
J. A. Rudinsky1,2 and V. Vallo1,2
1Oregon State University, Corvallis, Oregon 97 331, U.S.A. 2Institute of
Exp. Phytopathology and Entomology, SAV, Ivanka pri Dunaji, USSR
ABSTRACT
Both Leperisinus fraxini and Hylesinus oleiperda possess the
elytral-abdominal type of stridulatory apparatus with the pars stridens on
the posterior medial undersurface of the elytra and the plectrum in two
conical processes on the 7th tergite, similar to species of Dendroctonus,
Pseudohylesinus, and Hylurgops. The stress and revalry chirps of L.
fraxini are single multi-pulse chirps similar in toothstrike number,
duration, and rate, but the attraction chirps are double and significantly
different in number and duration. Both stress and attraction chirps of
Hylesinus oleiperda are double chirps and differ significantly from those
of L. fraxini in several parameters. L. fraxini is a bigamous species, one
male with two females, and each female occupies one arm of the biramous
gallery. The female L. fraxini produces the aggregative pheromone.




 David -

 The beetle in question is commonly called the Ash Bark Beetle.  I think
 it's Leperisinus fraxini, instead of varius, simply because of the pattern
 on the elytra.

 Elisabeth,
 It could be a Scolytid beetle, they look like this and will emerge from
 wood with bark in huge numbers.
 I do not have any pictures of any with such markings.
 You could ask Uwe Noldt in Germany, he is the best woodborer expert I know

 Dear pestlist-Members

 Thank you very much for your fast answers from around the world!

 I was looking for pictures of the anobium punctatum and the Anthrenus
 verbasci in the Internet and I dont’ think the beetles are anobii. But,
 maybe I’ve got both of them and the anobii aren’t beetles yet…….
 There is a lot of „wooden powder“ on the wood…
 L
 I didnt’ want to sent pictures which are too heavy… but unfortunately
 then you see even less…
 I send you one which is not reduced concering the size, but even then you
 can’t see it properly I guess.

 The beetle itself is about 3 millimeters in length.

 I called an expert who is coming today – so I will soon know more about
 the specimen and the problems/risks, I hope…

 But I’m glad to have some help from museum-experts as well!

 Best regards and thank you again

 Dear Elisabeth,

 I agree with Monika Åkerlund, it is essential to get a correct
 identification of the beetles. Only then will you know where they are
 coming from and what action, if any, is necessary. They do not look like
 Anthrenus or Anobium because they are the wrong shape and they have what
 appears to be a strong spherical antennal club. But more than that it is
 difficult to say because the photos are not very clear  (i know it is
 difficult to get good photos of small insects without specialist
 equipment).  Perhaps you could send specimens to your national museum to
 get them identified?

 Let us know how you get on,

 The beetles should be identified by an entomologist.
