Greetings friends,


I was able to very effectively clean mold (or at least kill it) off beetles and other insects by applying with a fine paintbrush a solution of thymol dissolved in ethanol on the specimens. That is one more treatment to try on your series of beetles.

Yes, that's the one Derek Woller sent a link to in the first reply to Andy's message yesterday.

I haven't tried it myself, but it certainly seems like a possible (and easy!) solution.

Plain household ammonia works well. Soaking a specimen will also loosen appendages for repositioning. I use an ammonia soak for genitalia dissection softening, too.

Lysol spray works well, too, and is good if you have a box or drawer of specimens to treat.

I have found a 50:50 solution of plain ammonia and water to be a good all purpose cleaner and have not had any problems with discoloration etc.

I don't have much experience with them but would an ultrasonic cleaner be useful in this case?

Hi all,
We received a recent donation of old beetles that are covered in mold (or mould if you like):
https://urldefense.proofpoint.com/v2/url?u=https-3A__flic.kr_p_25CSMCf&d=DwIFAw&c=Cu5g146wZdoqVuKpTNsYHeFX_rg6kWhlkLF8Eft-wwo&r=-lUMCZ4RK28H4qvcd3vmEBuyVJHHG0OpDzFenR9wX-A&m=2f77qDcaXPdLkYYrvCV5fBMwY1kq1WYL3-N4FitABag&s=O-tV4Aj5vHs1B8fvNtbtf0_NPQ6PvQiPquArjvptl1M&e=<https://urldefense.proofpoint.com/v2/url?u=https-3A__flic.kr_p_25CSMCf&d=DwMFaQ&c=Cu5g146wZdoqVuKpTNsYHeFX_rg6kWhlkLF8Eft-wwo&r=-lUMCZ4RK28H4qvcd3vmEBuyVJHHG0OpDzFenR9wX-A&m=n99OTuf82aDZt2HqKQC9Ft7gVrvQbOw8TuSLMKlm8ow&s=ECMd4FvuQHYo82b0gXuh6HlbhMdvgQLv5jK-1Uw-gLM&e=>
I was hesitant to accept them, given their condition, but the donation came with $$$ and the specimens appear to otherwise be in great shape.

Can anyone recommend a treatment? I considered removing the mold mechanically with a fine brush. That would be labor intensive, but the collection is relatively small (about two USNM drawers).

Thankful for any help,
Andy
