Hi Claire, You are right to look for the source of the infestation. Since they are somewhat ubiquitous, I suggest that you follow recommendations on the Museum Pest Network site. https://museumpests.net/
1. Learn about the pest – what is its life cycle, preferred foods etc. (another words, why might it be there) * Your actions will be based on your knowledge of the insect’s behavior and preferences 2. Locate source (if there is one). 3. Isolate affected objects (or things) if you find them (that will buy you some time in determining treatment) * Use treatment options that are practical : thermal (freeze or heat), anoxic, etc * Treatment is determined. In part, by what objects are being infested * please try to avoid the use of pesticide if possible 4. Improve housekeeping – thoroughly clean all spaces affected. You want to get rid of all life stages – since it appears that there are adult critters. 5. Monitor using blunder traps. 6. Repeat process as soon as you find additional beetles. All of this information can be found on the Museum Pest Network https://museumpests.net/ Good luck.

Unfortunately no, seems like they are throughout a section of my collections storage, we're going to try to narrow down the source point today. Does anyone have suggestions for mitigation? I don't have cold storage onsite and am unsure about using fumigants. Any suggestions are welcome!

I have the unfortunate pleasure of having a number of samples if the photos aren't ideal. All adults are between 3 and 5 mm long. Thanks for your help!
