Hi Anna, First off, where were the traps that caught the dermestids? Were they inside cabinets or on the floor? Are the contaminated traps close to each other?
Second, do you know where the spiders are? Are there areas that are hot spots for spiders. That might indicate a hot spot for dermestids or other pests. The spiders are thriving on something. Check the housekeeping around the hotspots. If they are inside cabinets freeze all the specimens according to PestNet instructions (or use anoxia). While doing this thoroughly clean your cabinets. If you can, look under the cabinets and in any crevices. Good luck. Feel free to contact me if you want to talk further.

Hello all, I recently checked and replaced the pest strips throughout my collection which houses birds and mammals skins and skeletons. On four out of 40 of my pest strips I found dermestid larvae (1-3) and three adults- one on a seperate strip on its own and the other 2 were on a strip with larvae. The adults were two different species- Dermestes lardarius and Anthrenus verbasci. We do not use any napthalene in the collection and I have checked inside the cabinets for any evidence of infestation or snacking and found nothing. There were also many many spiders on the strips as well. I increased the number of pest strips and put some insdie the cabinets close to the guilty ones. Will you advise if there is any aditional action you think I should take to protect the colection? It's not a small collection- we have 58 basic museum cabinets and 20 tall, two door cases. Thank you in advance! Anna -- Anna E.
