If you can’t break the cycle you have to start thinking of voids where crickets, rodents, or birds could be expired…. one dead cricket can support a lot of dermestids. Look where mass accumulations of dust have built up over the years. Above in ceilings, below under floors, behind things that haven’t been moved in years. Look in plumbing chases if they have access door. If you have access to a borescope poke that in every crack you can find and under every exhibit case. Crawl around on the floor with a flashing looking under everything. It’s detective work and takes time to solve the mystery. I find it helps to just be in a space before anyone else is there and just look around and study it for voids and hiding spaces and poke around. JTV

External Hi Rachel The best I can suggest for this photo is a Trogoderma larva. They are known to feed on both plant and animal material. Hopefully you can identify a likely source of infestation with an enhanced trapping programme. Good luck!

It’s about 4 mm long. My museum has a history of carpet beetles, but this is a lighter colored larvae than the Varied Carpet Beetle larvae that we typically find. I recently started seeing what I think are adult drugstore beetles in some of my traps, but can’t seem to find any photos of what their larvae looks like. A side note, we try to keep the museum well vacuumed, and do rotations of freezing items from the exhibit cases, but can’t seem to get a handle on the beetles. I also do an occasional dusting of diatomaceous earth along the edges of the carpets in the museum. What am I missing? Are we forever doomed to have these in our museum, since they seem to have taken up permanent residence?
