I also see a psocid on the trap indicating that you have some moisture in the area - the psocid is below and to the left of the speck of dirt. Some of the other debris on the trap (upper edge) kind of looks like larva that have been eaten by other bugs. How long do you leave your traps out? I have seen situations where a trap with dead things on it becomes the food source. The other question I have is how many dermestid larva are you seeing? 1 or 2 occasionally, 10 regularly or a whole bunch? The traps should be able to tell you where the worst of the problem is.
I use a bodelin proscope - another digital microscope - for this kind of thing. If you are in the market it is worth checking into. http://www.bodelin.com/proscopehr Good luck, Gretchen Anderson Conservator Carnegie Museum of Natural History.

Is there a chance you could take a higher resolution image? You can send it to me off list if you want. I'm not an entomologist, but there are certain pests that I can confidently identify.

It's not a great image, so I don't know how much it will help, but that's what I'm looking at. I'll try putting some traps in areas with more light and see if I catch any adults; my traps are mostly in dark corners now. Fluorescent lighting is the only source of light, the windows in the building were covered with plywood. I've found them in traps in various place throughout the building, so controlling them will likely be a pretty big challenge.

There are a few reasons why you might not find the adults. One could be that you don't currently have any; once they laid their eggs they probably left your building or died somewhere. The larva will eat the dead adults, thus destroying the evidence. The adults are also attracted to light. Where are your traps? If you have windows or other light sources in the area where you've found the larva, try putting traps near those light sources. Carpet beetles are incredibly dangerous for your collection. Try to find out where they are coming from and isolate any infested materials as soon as you can. Check items closest to your sticky traps, and add more traps to help pinpoint where they're coming from. Carpet beetles can thrive just on hair and debris that naturally accumulates in corners or in cracks in the floor, so I'd recommend a thorough cleaning using a vacuum with HEPA filtration and disposing of the vacuum bag immediately afterwards.

They're small, fuzzy things that I'm thinking if not carpet beetle, then some other sort of beetle larva, but I'm a bit puzzled because I haven't trapped a single adult beetle. Does anyone know why I would trap just the larva and no adults? Or is it maybe something else that just looks like beetle larva? Is there such a thing? Any help would be great. Unfortunately I don't have a photo of the actual ones that I caught.
