Christine Ford - I noted in your response, you mentioned "tons of spider beetles." Often spider beetles are generated from grain-based rodent baits and rodent feces. May want to scout around looking for old rodent bait.
You are right on with old glueboards producing other pests, primarily carpet beetles. It is uncanny how adult carpet beetles can fly to a glueboard loaded with dead insects, lay eggs on the carcasses, then the larvae mature into adult beetles, which then either lay more eggs on the carcasses or fly off to infest artifacts and exhibits. All the while never seeming to get caught by the sticky trap! So the next time you see a pile of "powder" surrounding dead insects on your glueboards, carpet beetles are bellying up to the "lunch bar." Thanks for your newsy note. I wholeheartedly agree; a vacuum cleaner is the number one IPM tool in any heritage collection storage and exhibition situation.

I think t helps. We also made sure all water coming off the rough is directed far way from the structure though gutters downspouts. We also created a hot zone around a historic structure in the middle of a ultural landscape . . . its just dirt without plantings . . . its more ifficult to maintain as the vegetation comes in . . . we do spray this rea with herbicides on occasion. There is another historic structure with istoric furnishings that we have not done this with. We have been hallenged for years in both of these historically furnished 1860s tructures with museum pests - dermestids mostly - tons of spider beetles n one. I've not noticed a change and I don't believe monitoring has been ble to show a change between when we didn't have the removal of veg from he perimeter or not. However, I think its still a good idea because at east when we look at the pest issues with experts in the field on how to est manage them . . . we can say that the perimeter is here. As pportunity allows, I would like to establish a hot zone around the other tructure . . . will keep it very modest - 6" probably - to be able to help aintain the cultural landscape of a residential area. We don't let any tree limbs or bushes come into contact with the structure.. e screen openings, e.g. attic vents. And we monitor to see what is coming nd going. And use an Integrated Pest Management approach . . . our best ethod is extensive housekeeping and being strict about a clean environment no plants, food, drink that pest can feed on - eliminate clutter where hey can harbor. Don't let sticky traps around so long that they become a unch bar for more pests. I have come to peace with the fact that (similar to noxious weeds) we will ever eliminate all museum pests at this site . . . we do our best to anage them below harmful thresholds. When we go above those thresholds, e start looking a some "hard" fixes . . . primarily chemical barriers.
