I have those in most of my bins, the person I saw used dermestids, but those things terrify me. Think adding superworms would be problematic? I know they can be voracious and have strong bites. It wouldn't hurt to experiment with this, for small collections I think it could be a decent way to keep a cricket supply going for longer.
Thanks for replying, I know a lot of people don't like to touch these bio posts lol.
