Okay, so now I've decided to go with Blaptica dubia roaches. I want to eventually have a BIG colony so what sized container do you suggest? Would somethinf like Rubbermaid work, or is the plastic rough enough for them to climb? Based on the size of container, what sized heating pad should I use and should I plug it into a thermostat to keep at about 90F? Should the heating pad go under the side with the egg crates?
