Flesh eating beetles (dermestids) are a pain to keep, smelly and you don't want them anywhere near your house. (they'll eat stuff in your house like furs, silks,wools, mounts) They're called carpet beetles because they'll happily eat your wool carpets.

Keep that in mind if you want to raise them.

Do an internet search for; dermestid colony

That should get you going in the right direction.
