I'm responsible for overseeing the IPM vendor contract and in-house program at our state-wide network of historic sites. We also have historic houses and buildings that are subjected to the same types of pest loads that you describe. I agree with the previous responses about structural exclusion and trapping. Those are two very essential components of any effective IPM plan. It sounds like you have the continuous monitoring in place with the pest log. The suggestions will work over time.
Two questions that you didn't address: do you have a strict cleaning (you did mention vacuuming the bugs regularly, and you'll still have to do that) and food policy inside the house? That's important to reduce food sources for insects that might be attracted to food residues, and for rodents. Secondly, I've inferred from your description of the problem that there might be vegetation growing close to the house. I looked at the image of the front of the house on your website, and the landscaping appears to be correct for the period on the street side. It looks like there might be plants close to the walls around the back. We had severe box elder invasions in one of our historic homes until we removed the box elders growing close to the house. The PCO should have made some comments about vegetation, if it's indeed a factor. Paul S.

Your idea of a black light in the attic is a good one. Get a supply of glueboards from Atlantic Paste & Glue Company of Brooklyn, NY. Any firm which supplies the pest control industry will have them in stock. Surround the black light with glueboards and put the thing on a timer so it will come on at about 4PM and go off at night. Flies usually rest at night. Other than sealing your building as tightly as you can, there's not much you can do about the Autumn invaders. A thorough glueboard program throughout the facility is a must in addition to the attic situation. Thomas A.

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.

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<http://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!
