I was intimidated about raise roaches. But didn't realize how easy they actually are! I ordered my Dubia Roaches from https://www.topflightdubia.com had them for about three weeks now. They are actually fun to watch. Can't believe I'm talking about roaches that away lol
i think 7-11 per sq inch is way to many. 3-5 would probably be better. To many beetles and they will eat some of the eggs since they are laid on the bedding. Also you dont want to have to many worms per container as it stun the growth rate.
