I helped maintain a dermestid beetle colony that was used by a natural history museum to prep specimens for display.
They are surprisingly easy to care for. It was just a large wooden box full of ripped up paper egg cartons. Drop a nice head in there and mist the cardboard with some water. Soon you have a nice clean skull. When not using it, just mist the cardboard once a week. The beetles just hang out between feedings.
For science purposes only, folks
