It could be moth activity, but look more like spider webbing.

Hello,
I'm attaching a photo of some webbing we found on a wool textile in one of our 
historic houses. We've had an ongoing problem with clothes moths and I'm 
wondering if this is moth activity, or do we have something else too.
Thanks,
Kate

Hi All,

I was wondering if anyone could identify what type of beetle this is. A few 
coworkers think that it is  a cotton beetle...but I haven't been able to find 
too much information on what those beetles do and what potential risks they 
might present to our collection. They have been found (mainly dead) near one of 
our doors that leads outside in groups of anywhere from 10-30 each morning. We 
have also noticed them near the door to an emergency stairwell in another part 
of our building. Most of the time they are dead-likely due to the sprayed 
barrier that we have applied to our exterior doors. But the ones near the 
emergency stairwell were still skittering around.

Any help on how to eradicate them and what they could potentially do to a 
collection would be much appreciated. Thanks!

Best,

RE: [pestlist] Drywood Termites

[Forrest St. Aubin]

Unlike subterranean termites, drywood termites enter a structure from the air, 
not from the soil. So far, you say that you have found them in one relatively 
small area.  Because drywood termite colonies are usually much smaller  and may 
be restricted to individual pieces of wood, they can often be eliminated by 
replacing the infested pieces of wood. Tenting and fumigation may well be 
unnecessary. But inspect the area around the infested location very carefully 
before proceeding.

Subject: [pestlist] Drywood Termites


​Dear Pestlist,



I am seeking advice on the treatment of drywood termites in the structure of 
one of our historic library structures here at UF.  We are aware that there are 
termites in the window frames in one of our archival storage rooms. The entire 
building holds special collections library and archival materials, reading 
rooms, exhibition spaces, and other public areas.



We are investigating the extent of the infestation, as well as the approach 
that our campus facilities group recommends. We know that on other campus 
buildings, the approach is to tent and treat, but moving our collections is not 
feasible, so any treatment must be done with collections in situ. As both 
termites and (possible) building-wide treatment are new issues in my career, I 
am interested in any guidance or resources that you can share.



Many thanks,

Fletcher

I believe Loxosceles reclusa, which would be called the Brown Recluse Spider, 
is the only species in the genus that occurs in Oklahoma.  We have had 
introduced species such as L. rufescens, the Mediterranean Recluse, in a few 
locations in NYC and these are established populations.  American roaches are a 
favorite food source. Tom also had collected this species from the Philadelphia 
area (he sent me specimens years ago).   There have been very few introductions 
of the Brown Recluse into NYC .  Loxosceles spiders can also go long periods of 
time without feeding.  Spiders in general have slow metabolisms.Actually the 
number collected by glue traps might not make a dent in the actual population.  
Here’s an example from around 2002 (J. Med. Entomol. 39(6): 948-951(2002)) 
where a colleague of mine investigated.  A person had been bitten during the 
time when the collecting process was undertaken, but not while living in the 
home. The spiders were both collected from glue boards (+- 800) and searched 
out (+- 1200) and hand collected.  You might want to read the article – there’s 
a description of the home and construction details.Online reference to 
story:Over a 6 month period, “…2,055 brown recluse spiders collected in a 
Kansas home of a family of four. Despite the abundance of spiders, no one in 
the family received bites from the potentially dangerous arachnids.”Lou Louis

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.

I have been monitering our museum using sticky traps spread every 10 feet

them besides sticky traps. I gather insecticides are largely ineffective.

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 From:

Hello All,

We just recently found a beetle that we have never seen before near one of our 
storage rooms. (see attached image)  The closest thing I can find to it in my 
bug guide and on the internet is a root borer but the color is not right.  This 
little guy measures roughly 1 inch and is metallic copper and dark green in 
color.  We want to make sure it isn't an insect that is harmful to museum 
collections.  Any guidance would be much appreciated. 

Thank you,

Diana Welsh

Re: [pestlist] invasion of bugs at house museum

[Forrest St. Aubin]

Hayley, yours is a problem that is not unique.
Spray, spray, spray -- that is all that many pest control operators can think 
of.  
Every pest that you have mentioned, with the exception of the hornets, is 
simply looking for a place to hibernate, not to live and breed.  None of the 
mentioned pests breed indoors. The cure is exclusion!  If your Board doesn't 
want to pay for it, get them together for a work weekend and invest in a case 
or two of a good quality caulk.  Almost everyone owns a caulking gun or two.  
Every single crack and crevice needs to be sealed up - completely.  Around 
doors, windows, under the siding, under the soofits, around utility 
penetrations, around ventilators, etc.  Replace the sweeps on the doors.  You 
get the picture. Then, keep the doors and windows closed as much as possible.
You'll be amazed at the results - maybe not this Spring, but certainly the next.

Subject: Re: [pestlist] invasion of bugs at house museum


Hello folks,
 
I am the new Curator of a house museum in South Dakota that has been overrun 
with insects, primarily cluster/wood flies, hornets, box elder bugs, and pine 
leaf beetles (stink bugs). We are experiencing warm autumn weather here and the 
seasonal pests have been thriving in the attic and throughout the warmer parts 
of the house. This is a giant concern asthetically (try giving a tour of the 
house without seeing or hearing the bugs fly around!), health-wise (no one has 
been stung by a hornet...yet), and of course for the artifacts (flies are 
getting mashed into floors, leaving debris, and may be a food source for larder 
beetles). We don't have an IPM in place, unfortunately it did not receive board 
approval. Hopefully, with renewed energy on my part, we can get something in 
place.
 
From my understanding, the flies in the house have been an on-going issue 
since it was converted into a museum ten years ago. Unfortunately, most of 
what I know about the pest problem is institutional mythology and very little 
has been recorded. What I do know is that until recently treatment has been 
superficial- mostly vacuuming when necessary and semi-annual pesticide sprays. 
The house was sprayed in the spring and the fall until 2008 because of budget 
cuts. Now the house receives a treatment (spraying around the foundation and 
inside around base boards and windows) in the fall, though it was not done 
last year because of early snow fall. Spraying period is something I would 
like to eliminate. Unfortunately, we simply can't afford expensive fly 
catchers. Earlier this year, our facilities manager fabricated our own version 
of a fly catcher for our attic- a blue light mounted on wood with removable 
sticky fly strips. While these do appear to be attracting flies, we don't have 
an adequate way to collect them so they form piles of dead flies, which is 
just plain gross.
 
I created a Pest Management Log to start keeping track of what kinds of insects 
we are finding, how many, where, and when. I have also met with our pest 
elimination specialist, who has sprayed at the house and our sister museum for 
years. We went around the house to identify routes of entry, but I would also 
like to know what is allowing them to continue to live and breed in the house. 
The treatment of an active pest infestation without understanding the cause of 
the problem is of limited value in the long run. My goal is to be proactive and 
address these problems for a longer-term solution than simply vacuuming up the 
bugs once, twice, three times a day.
 
I know that my situation is not unique. Bugs are a problem wherever you go, 
especially in older buildings. I am writing to those of you out there that may 
have experienced something similar and are willing to share (horror) stories. I 
also want to know what resources are available that are geared specifically 
towards museum pests (aside from museumpests.net, of course). Also, we are on 
the National Register, so what are we allowed to do then? And what about the 
more unusual pests- box elder and stink bugs- how harmful are they to museum 
collections aside from leaving a residue? Are there acceptable levels for 
these pests to be in the House? Lots of questions, but any response will be 
helpful. Thanks for your time!

Re: [pestlist] Sow and Pill Bug problem

[Forrest St. Aubin]

Tara, this sounds like a DIY project to me.First, it's not likely that the pill 
bugs or sow bugs are coming from the drain; more likely they are simply 
attracted to the drain.  Might there be a lot of organic mulch surrounding that 
stairwell?  If so, that's the source.Now, what to do about them --It sounds 
like there is a moist environment at the bottom of the stairwell.  If so 
diatomaceous earth will not work well.  It will simply cake!  But let's do 
three things.  First, remove that drain cover once again, cut a piece of 
aluminum or copper screen wire the same diameter as the drain, Place it on the 
underside of the drain cover and set the two pieces back in place.  Don't use 
ferrous metal screen, It will rust through in no time at all!Next, Door sweeps 
come in many configurations.  Get one that is adjustable so that it will seal 
properly.Now, let's take a look at the environment surrounding the stairwell.  
If there is organic mulch of any type, remove it and replace it with inorganic 
( lava rock, creek gravel, pea gravel, etc.) mulch.Finally, I said three 
things, but let's make it 4.  Place an insecticide containing bifenthrin, 
permethrin or beta-cyfluthrin on the first 3 or 4 feet of the floor inside and 
outside of the door. Apply that material up on the door frame and baseboard.  
Any of those materials should give you about 3 months of protection.See if 
those measures won't give you some relief.Forrest E. St. Aubin, BCEChair,

12:09 PMTo: pestlist@museumpests.net Subject: Re: [pestlist] Sow and Pill Bug 
problem Hi all-     I have a problem with pill and sow bugs coming 
inside a portion of our library.  The area on the exterior has a drain at the 
bottom of a cement stairwell, which leads to an old wooden door. The door 
enters an area of our manuscripts processing area and they are inundated with 
these pill and sow bugs - two large sticky traps can be filled in a week's 
time.  A sweep has been applied, but because of the age of the door, the sweep 
does not work well enough.  The drain cannot be closed off.  Maintenance is 
unreliable around here and I don't expect that the drain will be well cleaned 
any time soon.     I took the drain cover off of the drain and saw that there 
are sow and pill bugs in the drain.  This is definitely the source of the 
problem. My question is this: can I put Diatomaceous Earth in and around the 
drain on the exterior and will it help the problem? Would putting the same 
underneath the door and the path leading to the door help as well? I just need 
a way to dry up the drain that won't hurt anybody or anything but the pill and 
sow bugs.     Will this be effective? Or does anyone have any other 
suggestions?     Many thanks,  Tara  *~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~  Tara

RE: [pestlist] moths and carpet beetles

[Forrest St. Aubin]

Lisa, there are several formulations of permethrin insecticide that are labeled 
for use on clothing.  There are also several lines of outdoor and sports 
clothing impregnated with permethrin.  Permethrin is used extensively by the 
armed forces and, properly applied, will withstand several washing before 
reapplication is necessary.Permethrin would be ideal for use in a working 
collection, such as theatre, as well as for museum storage.When applying 
permethrin, only apply to clothing, never directly to the skin. Forrest E. St.

---  Hello 
Everyone,  I apologize for this long-winded email.  A local university has 
asked me  for some help involving a pest infestation in a costume collection 
and I  thought I would ask you.  This is not a museum collection but a  
working collection that is used in the theater program, etc; however,  it is 
comprised of period clothing from the 20th century.  There are  about 1900 
hanging textiles and another 2000 in boxes, and they are kept  in a 12' X 60' 
room.  When the collection first came to them, it showed evidence of  
moth/carpet beetle damage.  At the suggestion of an entomologist, the  most 
vulnerable items in the collection were frozen, the wool and silk  items were 
vacuumed with a mesh screen, and the room that houses the  collection was 
periodically fogged with a fabric safe pesticide.  However, the infestation has 
returned.  An exterminating company has  recommended treating the room with a 
long lasting micro-encapsulated  chemical using controlled release technology 
to be done on a regular  basis for a year in 3 month intervals.  Are there any 
other options or suggestions to be considered before this  chemical treatment 
of the room?  Bear in mind, this is not a museum  collection, and the logistics 
and cost of freezing the almost 4000 items  prohibits freezing the entire 
collection.  THANKS!   --  Cindy Gardner Director of Collections, Museum
