I agree with Pascal's cogent explanation below.  One of the key components
in an effective IPM program is exclusion/structural integrity.  For any
type of trapping program to work, efforts must be taken to physically
exclude the pest from the structure.  If the 'conservators' were speaking
in the context of large, porous structures such as warehouses, old
barracks, hangars, or museums in re-purposed historic military buildings,
then their warnings could be applicable.  As a blanket statement, however,
it doesn't make much sense.

We have used pheromone traps in the Minnesota History Center to track down
the source of a clothes moth infestation and they worked very well.

Challenging problem.  I have a few questions:
- Do you already have an effective IPM program going on in the museum?  If
you do have recurrent pests, what are they?
- How long is the duration of this installation?
- How close can people get up to it?
- Is it in direct line with an air register?

I have to respectfully disagree with the plexi vitrine suggestion as I
doubt that the artist would accept it.  It would negate the concept of
'impermanence' of the piece and be visually intrusive.  I do advocate for
plexi glazing on paintings in public buildings and sites, and for barriers
to objects and art objects, but it might not be warranted in this case.  It
would certainly create a separation between the two components of the work.

What are the materials and types of objects that have the contamination?

"Mothballs" are usually either naphthalene or paradichlorobenzene, but are
highly volatile organic chemicals (VOC's).  The TLV for p-dichlorobenze is
75 ppm, and napthalene is 10 ppm.  You'll need to use organic vapor
pesticide-rated cannisters on your respirator, if you use one and a fume
hood is recommended as well.

Most likely, the best method will be the use of an absorbant to pull out
the odor molecules.  More information on the objects will be helpful to
make more specific suggestions.

If you have Ecolab in your area, you might want to add them to your list of
potential vendors.  We have contracted with them to service our 22 historic
sites around Minnesota for the past two years and have been satisfied with
their service.  We initially contracted with another international company
that did not perform well, so after reissuing the RFP for the next contract
period, we went with Ecolab.  They operate under IPM best practices and are
familiar with the concepts and procedures involved.
Our sites include modern visitor center/museum facilities as well as 19th
and early 20th century historic structures.

 Hello All,

 ** **

 This is my first time using the Listserve. I hope this finds everyone well.
 

 ** **

 As you can see from my signature block, I work for Harvard University. One
 of my primary duties is managing the pest control program. I recently took
 on this responsibility about a year ago. We are in the process of reviewing
 all aspects of the program, including vendor services. It is not that we
 are dissatisfied with our current vendors, and I realize that the list
 serve is not to be used as a way to promote one’s business. However, we are
 curious to know if there are pest control vendors that specialize in Museum
 related issues.

 ** **

 Any assistance you can provide would be greatly appreciated.

 ** **

 Thank you.

Will silverfish travel up pipe chases?  I know that they can't jump, but
can run quickly.  I don't have information on their climbing ability.  We
were getting recurring infestations in a storage area away from any
moisture sources, so my theory was that they were coming up pipe chases
from the sub-sub-level utility level below storage.
Just a thought.
