[pestlist] clothes moths infestation at home

I've recently discovered that I have clothes moths at home.  I'm pretty
sure they are casemaking (found some empty cases under a rug and in a
couple of sweaters but have yet to find live larvae).  I've already caught
an adult catching a ride on me and I'm concerned about infesting our
collection area.

Since it's at home I'm willing to take more drastic measures than I would
at work.  Does anyone have suggestions beyond thorough cleaning, inspection
and bringing everything to the dry cleaners?  I've found them throughout my
apartment.  I am hesitant to call an exterminator unless it's necessary.

Thanks,
Kirsten

Hello Patty,

My entomologist suggests a psocoptera and says to check your books as that
is what they like to eat.

RE: [pestlist] FW: [OSG] FW: question about use of Vikane on collections

2010-04-29 Thread Hascall, Jamie, DCA
I have not used Vikane as a fumigant as our museums use a system of CO2
fumigation. A quick search of the literature brought up this piece of
research from the University of Florida via the Getty Conservation
Institute. http://www.getty.edu/conservation/science/abstracts/1.5.html
This abstract seems to put the efficacy of Vikane on a variety of pests
into question. 

 

I was wondering if there was a reason why a regime of anoxia might not
be more appropriate? For small amounts of objects an oxygen scavenger
system can work but for larger volumes a containment bubble with CO2 or
Nitrogen may be needed. You may want to check with the IPM resources
listed below for other research information and possible vendors.

RE: [pestlist] Clothes Moth Eating Habits

2010-04-29 Thread Anderson, Gretchen
There are many many instances of "clothing" moths infesting exhibits and
buildings.  I recently saw an instance where the wool carpeting in the
auditorium of a museum was literally shredded by moths and had to be
completely replaced. Moths do not differentiate between storage and
exhibition - they are looking for some thing edible in an environment
where they will thrive. Taxidermy is highly susceptible.  I recently
cleaned a deer mount that was full of moth frass, most likely from when
it was on exhibition (sorry no records).  Wool carpet and other wool and
protein based items are all susceptible. And it is a critter that is
very difficult to completely eliminate once they are established.

 

Also remember that while the moth larva might not eat the skin, it can
and will damage the skin, graze along the surface, and is capable of
boring through a skin.  I have seen inuit gut parkas that have been
damaged in this way.

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. :-)

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.

Hi Molly,

Trust me, collections can become infested with webbing clothes moths
while on display... Another good reason to display collections in

Hi Molly,
I should make it clear that my moth problem is not in the collection  
but in the fabric of the building ( as far as I can deduce)   I think  
the moths are living under the floors (it's an old building with gaps  
between boards and so stuff falls down there)
