Here is another idea that may work around your issues: Capture a few local roaches and start your own colony. I did this with Blatta lateralis and also with Blatta orientalis. No shipping. No cost. If you are feeding out your CB baby roaches, no risk of pesticides. If any escape, well, they were already there to begin with. If you get too many, freeze or incinerate the excess. Or give them to friends. Or leave them in the mail box of the guy who cut you off in traffic and then flipped you off. Not saying I would ever do such a thing…
