Re: [PestList] Dermestid beetles potentially infesting fossil specimens

Hi Everyone, I would not recommend heat treatment, you may alter the chemistry of the minerals/ damage them. Nor would I recommend freezing. We visually check for pests, and ensure that when material is coming in any old packing materials have been replaced (as this is the larger issue when

Re: [PestList] Dermestid beetles potentially infesting fossil specimens

I'm not too familiar with fossils, but my understanding is that they are mineral rather than organic. If that's the case, would a heat treatment work? Perhaps in an oven at 120F / 50C for 24 hours? Afterwards, maybe a three month quarantine. The good news is if the fossils are clean there
