I've tried to raise crickets to feed a pet bearded dragon. I followed all the guidelines, but generally could never even keep them alive let alone get them to reproduce. I don't think this is quite as easy as it's made to sound.
It's odd because you see crickets everywhere in the wild, they must be pretty hardy, but I utterly failed trying to "farm" them.
I breed Guyana roaches to feed my pet tarantulas. They are hardy and easy to breed, plus they don't smell or make noise and they can't climb walls. They give live birth and don't infest homes. I keep them in a large storage bin with a screen lid filled with egg crates, and feed them fresh fruit and dry cat food once a week. I live in a small apartment and guests don't even know they're there unless I point them out.
There is absolutely nothing I can think of that I'm afraid of, but those bugs give me the shudders! Ugh!
Props to you for being able to do that!
