ugly dog The beetles are a strain of carpet beetle, that will eat the remaining flesh off of the skull after you skin it and cut off the big peices of meat. Its really pretty easy you just have to take care of your bugs so theywill eat fast and multiply. Then all you have to do is the bleaching process. Its not as fast as boiling the skull, but itsnot as much of a pain, the bugs do the work, and do it better than boiling, you just have to wait and tolerate the smell.
