Don't keep them in the house... the smell is quite putrid. Also, it takes months to start a good colony, sometimes over a year. This is because when they send you the beetles, they send you mostly adults, but it is the larvae that does most of the chomping, so it'll take them a while to produce enough to get a good fast system going. Be careful who you order from, some of the beetles from less that reputable places could contain mites or other parasites that kill the larvae. It is best to use two containers I found, so that way you can sort of dump them all in the other one when you need to clean out your main container. It will need to be cleaned once every couple of months or once every couple of weeks depending on how many skulls or bones you plan on cleaning.
Be sure to plan for when you're not going to be cleaning skulls also. Feeding them roadkill or the neighbor's wild cats seems to work
