The roaches are B. lateralis (a.k.a. Turkistan roach). I tried the phoenix worms and had a bad experience with that. They were coming out whole and still alive. I wasn't told you needed to poke them with a pin first. I found this out from the supplier thru Josh's. I've been looking for a place near NC for silkworms, just haven't found one yet, so thanks for the info. I just want to keep them healthy and happy.
