Moving again?

Tonight I smuggled the two cockroaches into my aunt and uncle's house; I don't think anyone knew what the plastic tub in the grocery bags was. Phew! Because after my mom's reaction to my participation in this project I don't want to tell my aunt about the new inhabitants of her home. Ricky and Sticky have been quiet, the haven't moved for the past couple of hours. While studying, I read that Madagascar Hissing Cockroaches like warmth and humidity. I put a couple of wet cotton balls into the container to hopefully add some moisture to the air; and if they get thirsty they can drink some water. I'm interested to see if I hear them moving around in the night; my bedroom gets pretty dark. One of the cockroaches has been sitting in the egg carton and the other has been hanging (better word?) on the wall of the container.
