RE: Beetle ?
Yes they are dermistid beetles, and you can get them at taxidermy supply stores. I ordered mine from a business that does skulls, they have a starter kit they send, and you get them started. The larvae(babies) is what does most of the eating, the adults will eat some, but mostly breed, and they do multiply quickly. They need warm dry environment, and from what I saw with mine, they will eat anything on or in the skull. The ones I had stunk so bad, you dont want them in your house or near it for that matter, I mean the meat they are eating is decaying while they eat it, but I guess if you had enough of them they would clean a skull before it had time to rot, but on average mine took 1-2 weeks for them to completely clean a skull, but I didnt have a large colony, or the perfect setup. I kept mine in a shed outside in large rubbermaid plastic totes, which were big enough to put in a couple skulls and put the lid back on. In cool weather I kept a heat lamp on the totes to keep them from getting cold. They did a great job of cleaning skulls, and I made a little extra money with them each year, but got tired of trying to find stuff to keep them fed through the late spring and summer months when I had no skulls to clean, and the smell was terrible so I gave my colony to a buddy who was interested,, but it didnt take him long to get rid of them.. One thing to remember is to freeze the skulls for a week or so after they are cleaned, to make sure all the beetles and larvae that may be left in the skull are dead and dont get into your home, and possibly on other mounts. They can destroy other mounts, and I was told they will eat holes in material, clothes, and even wood, but I never tested them out on that.. Hope I helped out some, let me know if you have any more questions.
