Hey james, are you thinking about the green banana roaches we talked about for future? I agree with Nightanole, it's an easy way to feed and if any of them escape, if I remember correctly you don't live in Florida? So they will not survive and breed within your house. Within around 24-48 hours the adult green bananas I have had of any species, die off once outside of their specific enclosure. They honestly need the specific requirements within it. I will be getting a Costa Rican variety (not sure if I explained that to you once I talked about replacing the colony) which that species has the bright colors of the regular smaller variety but is much closer to the size of the giants.
