Dermestid Beetles are beetle family Dermestidae under the order Coleoptera that feed on dead organisms. Specifically, dead insects in this case. They can be a real pain and damage to the museum collections as all they do is eat, eat, and EAT those food! or the valuable collections to the museum scientists.
I first encountered while living in rather an old apartment complex where pest management is poorly done. I’ve been seeing number of silverfish and dermestid beetles every weekend while cleaning. Now I moved to a house, hoped not to see any of those pest, but….. THIS!! Must be from the time when I was in the apartment.
All I have to do is just place that entire unit tray into the freezer to freeze them to death. I think this particular infected specimen is the most recent collection placed in this unit tray, as well as in this drawer. However, as the specimen is collected on July 2016, I’m unsure whether it has infiltrated at the time of placement, or in a later date. I’m hoping there isn’t any hole or gap anywhere on the drawer. Collections in this drawer is non-scarabs, that I rarely ever touch, which may be the reason that I finally, after the entire leg chewed up, found the infection. Although, there are some valuable (as in rarity) collections in this drawer, so I’m afraid to see any pest inside. I hope that one unit tray is the only one that had the dermestid beetles.
