Actually the easiest way is to find a carcass and pick your own but then you have to deal with infestations of mites, etc. School supply houses have them. I use Carolina Biological..... www. carolina.com ..... Type in dermestid and it will come up........$17 for an assorted set which has beetles, larvea and pupa ( I would get 2 to start a colony)........Lot's of info on the net on proper containers....I personally use big plastic containers (100 quart w/ lid) from wal-mart and card board for the bedding material.....If you don't have skulls to clean they like high protien dog food......They have to be kept between 70-80 degrees if you want them to eat and cold temps <40 degrees will kill them so you have to have a place inside for them.....
