Hey all, Just wanted to share my first completed skull after starting out and acquiring a starter colony of Dermestid beetles from Ken at Kodiak Bones and Bugs, thanks again Ken these bugs are great! I'm brand new to skulls, bones and articulations so I'm fairly happy with the final results of first attempt. I have a bunch more different specimens in the freezer that I will be working on over the coming months so I will be sure to share as I go. I used 50/50 Ammonia/cold water for a week and then 3% hydrogen peroxide for a week with a little bit of gentle toothbrush work in between. What do the pros think? Thanks!
