They are most likely carpenter ants. From my experience, they do swarm for one 
day, although it is usually the first really warm day in the spring, at least 
in Vermont. Then they disappear for another year. If they swarm inside a 
historic house, yes, you need to worry. It most likely means that they have a 
nest in the wood in the house. They do not get nourishment from the wood so 
they are not as destructive as termites, but they do build nests, and if they 
are swarming in the house, they probably have an established nest that could 
weaken the wood in that area of the building.

Look for damp areas of wood, most likely around the sills. Any place water 
comes off the roof, hits the ground, and splashes back against the sill? Or 
perhaps wood under a sink where there could be a leak. Have you seen any of 
these ants occasionally wandering around the house? If so, examine the sills of 
the building near where you have seen the ants. On a quiet day, you may even be 
able to hear them chewing.

We have had carpenter ants in several buildings. They actually damaged the end 
of the logs on a log building over a 50-year period to such an extent that we 
had to take the structure down an build a new one. You need to have pest 
control folks find the nest and knock it out with the appropriate insecticide. 
Then remove and replace the damaged wood. I have never seen carpenter ants 
infest or harm any wooden artifacts. Powder post beetles yes, but not carpenter 
ants. That does not mean they could not cause harm, but it would have to be a 
pretty damp piece of furniture.

Flying ants recently (on a day at the end of August) were seen swarming inside 
an historic house set within parkland. They dispersed within a couple of hours. 
No specimens were kept, and I only have this one bad photo. Is there anyone 
able to identify the type of ant? I did not see them myself but the conservator 
on site thought they looked like pavement ants, while our pest control 
contractor identified them as carpenter ants. Do I need to worry? The house 
does have museum objects in it, especially wood furniture.

Any information/thoughts are most welcome!

We have been dealing with squirrels in two buildings in particular for
years, and years, and years...here are some ideas: 

1. An ongoing live trapping program will decrease their numbers over
time if you keep at it and take them several miles away before
releasing.  
2. Plug up the building with cut-to-shape boards and well-fastened
hardware cloth, inspecting and sealing every inch of the building
especially at the roofline from outside and inside wherever possible.
Cover any chimney openings.
3. A weasel that had been injured on the road and nursed back to health
by a local wildlife shelter was released in the area and kept the
squirrel population down for several years until it either wandered off
or died. Then the squirrels came back. They are nocturnal so visitors
and staff never saw it.
4. On a similar vein, Shake Away which is fox or coyote urine cast
onto a cat litter like material sprinkled around the building and in the
attic was effective in getting squirrels who were nesting in the attic
out, even taking their babies with them. It is available on-line.
5. An ultrasonic unit that cycled through various frequencies may have
worked for about a month when first installed, but they quickly get used
to it. Not worth the money from our experience.

In summary, no easy way to keep them out. Just attack from all
directions with various methods and be as diligent and persistent in
eliminating them as they are in getting into your buildings.

Hello all,

One of our historic buildings, a log cabin, has squirrel issues.  We've
tried plugging the holes with hardwire cloth and copper mesh, but the
squirrels just pull it out and use it as nesting material.  The building
has double walls with a gap in between, perfect for stuffing with apples
and raising squirrel babies.

A member of our maintenance crew brought in information about an
ultrasound emitter that acts as a repellent.  (This one is called
YardGard.)  Does anyone have any experiences with these kind of
devices and whether they work?

Thanks,
Sam

This is interesting - 

 

Looks like the Return Receipts were implemented at nps.gov, which means
when something from the list goes out anyone at nps.gov, a return
receipt is getting sent back out to the list. I'm not sure how it's
implemented but I'm thinking that it's not under control of the person
it's getting sent from. The reason I think this is because one person
from nps.gov sent me something asking if we could get rid of them - the
amusing part is they probably don't know that their email also generates
the return.

 

Just so you all know, we monitor the list and when we see these we try
to institute a rule in the email system that will block these types of
emails, as well as any spam that may get through. It does sometimes take
a few turn arounds to get it correct.

 

leon ...

 

p.s. the other reason I'm sending this is to see if the new rule works.

I have been using traps with pheromone attractants for both webbing and
case making moths and it would be useful to have one to attract both
types of moths as well as black or varied carpet beetles. Perhaps the
cost would be prohibitive, but if Colin is interested in pursuing it, I
so go for it.

Sorry Tom, I have to disagree. What you describe is what you say it is;
A blunder trap. There is no doubt that the advances is pheromone
technology has enabled the development very effective and accurate
monitors, capable of detecting very small or new infestations. Blunder
traps simply demonstrate how severe an infestation has become. For
insects and even mice to be caught this way indicates severe
infestations.  Not something of much use when you consider many museums
following good IPM protocols regard one moth as a serious infestation!
 
I'm not 're-inventing the wheel' but rather trying to develop something
which may bring us into the 21st century. A trap with a number of
pheromone lures which will attract insects even if there are very few
around; at a fair and reasonable price.
I can well understand museums using ineffective blunder traps,
particularly when we all have to control costs. What I am trying to
develop and offer is something in a similar price range which actually
works!
 
All the best

Barbara -
 
As far as the museum community goes, flat, cardboard glueboards,
manufactured by Atlantic Paste  Glue Co. of Brooklyn, NY or Bell
Laboratories in Wisconsin and others are the best multi-functional
insect traps on the market today.  Even flying insects end up in these
blunder traps.  Not only can you determine the kinds of insects
getting caught (indoor or outdoor), you can often determine from which
direction they're coming.  As an added bonus, mice can be caught on the
larger ones.  And they're cheap!  Let's not reinvent the wheel.

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!.

Thanks Rick and Steve, 
I should have mentioned that our storage room is in the center of a
defunct parking garage. There is no food source for 40 meters or more
from the room. I think that's why the corrugated glue is appetizing,
perhaps only by the nesting baby squirrels. In our trapping and
observations we haven't seen any other rodents... yet.

The Tanglefoot and Shake-away both sound promising. I wonder if they've
ever been mixed together... what a nasty idea. In the meantime we've let
a confusion of weasels loose in storage (just kidding).

If you have squirrels in your storage areas you have more issues
than just the squirrels.  If squirrels have access to an area, so do
nearly all other agents of deterioration, including other even more
damaging/dangerous vertebrates like bats, coons, cats, etc.  There are
more variables to consider when dealing with and predicting behavior of
vertebrates than with arthropods but squirrels should be easier to
exclude than arthropods from even the most basic of collections storage
areas.  Glue is certainly not a preferred food source and, though
cardboard is a good nesting material, these are not resoiurces they will
work too hard to obtain under most circumstances.  As with the previous
posts about hibernating insects, make sure all holes and access points
are patched and sealed.  With squirrels it may be necessary to cover an
area with sheet metal since, once they find a place they like to sit and
gnaw, they may return to a wooden patch and open it again.  Ammonia
soaked rags placed or tied in the area are irritating and usually
avoided.  Tanglefoot is annoying to them.  Repellents are a good
occasional control method but squirrels can habituate to them; use them
in conjunction with other control methods.  Monitor historic and
potential entry points rigorously and make them unpleasant places either
with the above methods, Christmas lights, monitors with squirt guns,
vegetation modification, kinetic sculptures, etc.

 

Relocation is usually a bad idea from both pest control and
ecological perspectives.  The squirrels either return or die miserably
from fights, starvation, weather, or predation.  Trapping and euthanasia
is the most humane and effective course, just like we do with all other
museum pests.  Squirrel populations can tolerate up to 80% annual
mortality and still maintain long-term stability.   You can use live
traps and CO2, big snap traps, and other control methods similar to that
used for rats, though local regulations vary because squirrels are a
game animal.  Sometimes it seems that the population learns to shelter
in buildings from a few individuals so concerted trapping for a few
seasons eliminates the problem individuals and for sometime later there
aren't any problems.  

 

Eliminating outside food and nesting areas for squirrels can be
difficult since these often come from legacy trees and their mast.
However, if squirrels are being fed near the building or are regularly
using garbage cans you can enact policies to manage this.

 

Also, I would approach the old lady who swallowed a fly method
of eradication with care.  In most cases this has poor results, at least
for the introduced animal which usually dies a miserable death and, if
not, it will negatively affect more than just the intended target.  Feel
free to email or call if you want to talk about your specific situation
and discuss particular methods.

 

In the meantime, I hope everyone will tell me about the
squirrels near them at ProjectSquirrel.org http://projectsquirrel.org/

RE: [pestlist] Clothes Moth Eating Habits

2010-04-30 Thread Rick Kerschner
My experience reflects Molly's observations. Whenever I have found
insect infestations they have been on particularly tasty artifacts,
e.g. taxidermy mounts, fur mukluks, wool interior of a carriage, that
have been in storage in poor conditions and not vacuumed for ages. With
one exception, I cannot remember a carpet beetle or moth infestation on
an artifact on exhibition that is vacuumed even only yearly. That
exception is our hunting lodge filled with taxidermy specimens. We did
find carpet beetles on the specimens, especially in the horns, after 55
years on exhibit and they had been there at a low level for quite a
while. However, this infestation was not due to detritus carried into
the building by visitors. The artifacts themselves were the source of
the food for the insects. 
 
Although I guess that it is possible for insects to be attracted to
small amounts of protein left by visitors as they tour our buildings, I
doubt that this source or nourishment is the cause of significant
collections infestations. Better to look for a dead bird or rodent in
the walls, or a high-protein artifact that had not seen the light of day
or the brush of a vacuum for years.

Thanks for that Thomas.  
I thought that WCM would eat skin as they attack taxidermy specimens,
leather and dried animal remains or is it only the fur, hair and
feathers they eat? I'm starting to realise our collections would be a
lot safer if we didn't let the public in the our museums. :-)

Heather -
 
When I give an IPPM lecture, I tell my audience a visitor drops
3 hairs and one fingernail per visit.  WCM larvae will readily feed on
the hair, but usually not the fingernails.  Carpet beetles will feed on
the fingernails.  I know of nothing, which will damage collections,
which will feed on skin cells.  The public doesn't drop feathers.
Generally I have found younger instars feeding on the debris in cracks
between floor boards and bricks in a museum.  Although I haven't seen
it, I am assuming in a large public museum, there's enough protein
debris for a WCM larva to complete its development and pupate utilizing
the protein materials dropped by the public.

This message was sent directly to me by someone who doesn't have access
to the OSG-L.

I told her I'd post it for her.

 

If anyone has thoughts, they should respond directly to Amanda Trum

Subject: question about use of Vikane on collections

 

Hello Ms. Riccardelli,

 

It was suggested that I contact the AIC Objects Specialty Group with my
questions about the use of Vikane to treat pest-infested objects in our
collection. Is it safe to use Vikane on objects that contain wool and
leather (specifically chaps and saddles)? Are there specific temperature
requirements in using it (like temp must stay above 45, etc.)? Is it
necessary for staff to wear HEPA masks or take any special precautions
when handling objects after they have been treated with Vikane?

 

Thanks for your help!

 

Sincerely,

Amanda Trum
