OK-- I haven't been able to read everything here about this infestation..but it sounds like I need to dump this colony? I have two bins, one with worms/pupae/beetles, and one with tiny baby worms/eggs/frass. The baby worm bin is totally infested, and I have started to see some bugs in the beetle bin.

What if I keep it all outside? The little bugs are harmless, other than infesting my house, right? I know that the meal worms will reproduce and grow more slowly in cooler temperatures, but otherwise is it OK to have them outside?
I understand microwaving the wheat bran before using, but is it possible that the bugs come with the meal worms? How would you prevent contaminating a colony that way?
