Seems like no one has mentioned sex pheromone traps for the carpet beetles.
Insects Limited makes all sorts of pheromone traps suitable for use in the
museum setting.

Hi Josie,
Since you are new to the IPM process, please remember that light traps, sticky
traps and other such devices are primarily for monitoring. They can help you
determine what species are present and the seriousness of the infestation,
then you can focus on elimination (or more probably reduction of populations).
Do not depend on these devices to eliminate your problem. You also have to
place the traps in correct orientation. Learning about the life cycle and
habits of the suspected pest will help you determine the approach.
You will find the https://museumpests.net/ extremely helpful in identifying
insects and other pests, learning more about their life cycles and strategizing
on how to deal with them. There is also information about how to find and work
with Pest Control companies.
Good Luck

Hi Josie,
With regards to the flies, a suitable ID would allow for more in-depth advice,
however Insect light traps will be a good non chemical control option, and will
allow regular analysis and trending.
For booklice, reducing humidity tp below 50% for at least 15 days will reduce /
eliminate the current population.
For Silverfish, these will also have numbers reduced with the humidity. Gel
baits / traps are available on the market for a more robust approach.
Any particular dermestids, you're currently dealing with? Deep cleaning, is
beneficial, Varied Carpet beetles are known to enter through open doors /
windows.
Many thanks,

Thanks for your reply, Richard! I understand your concerns and share them.
Currently I am just trying to hear from experts in the field because I am a
novice at IPM!
We experience flies year-round in a few of our buildings, and I have also
guessed that they're probably cluster flies. I would love to hear your
recommendation options for treating them! They have definitely wreaked havoc on
our cultural center and are probably multi-generational. I have been trying to
understand them since I started this job about 7 months ago and while they are
always there, they are worse in spring and summer. Like I said in my first
email, we've attempted to seal this building but with little result.
Any recommendations for mitigation and prevention efforts for the silverfish,
booklice, and dermestids? I'm following the basics of IPM lined out in
FUNdamentals of Museum IPM by Christa Deacy-Quinn. I monitor with sticky traps,
diligently clean collections and exhibit spaces, we've tried sealing potential
entrances, we keep food and water out of collections spaces, we've effectively
been able to freeze past infestations, etc. I'm not sure what else I can do
honestly, which is the only reason I'm considering pesticides. I understand and
agree that they're not the most environmentally responsible choice, but they
are currently my last resort.

Josie,
I would generally discourage efforts to spray the outside of the building, as I
think it would neither be particularly effective nor sustainable. One could
also argue that it wouldn’t be environmentally responsible.
What kind(s) of flies are entering in abundance, and during what seasons? Are
you burdened with them now? If so, these likely are cluster flies that have
been overwintering within the attic or wall voids, but then cause havoc within
the human-occupied spaces. There are options to better manage these flies that
don’t depend upon frequent and widespread pesticide applications.
I anticipate that dermestids, booklice, and silverfish are already in residence
within the museum. Accordingly, I’d encourage mitigation and prevention efforts
inside to protect your accessions while continuing to exclude entry of new ones
from outside.

Subject: [PestList] Working with pest companies
Hello all,
My institution struggles with pest management due to the nature of construction
and age of our buildings. Some of our biggest threats are dermestids, booklice,
and silverfish. We also play host to many flies, which not only poop on our
collections, but provide a meal for and attract more dermestids. Attempts at
sealing our buildings have been made but we still struggle. Our problems are so
extreme that we're considering spraying the OUTSIDE of our buildings to help
mitigate these risks.
The pest company has recommended the following products: demand, Temprid, and
Delta guard granulars. I've spoken to the pest company about wanting to keep
the pesticides outside because we're a museum, and they understood. I was
hoping to receive some opinions about the safety and efficacy of the use of
these chemicals and others at your institutions for pest management. Please
feel free to share any experiences you find relevant to this topic, positive or
negative! Thanks.
