Bred invertebrate myself

I maintain a moderate sized colony of dubia of around 1500-2500+ at any given time. These guys are super easy to care for, and they aren't very menacing as far as roaches go. They are the best feeder insects around in my opinion! Many different animals enjoy them such as reptiles, insectivores, amphibians and large fish. They also make cool low-maintenance pets as they do not bite and are easy to contain.
Dubia are super easy to house because they don't climb or fly. They don't make noise or stink either. In large numbers they do have a smell that reminds me of dead leaves in the Fall. The adults are easy to sex because the males have large wings while the females look like your typical exotic cockroach. These guys give live birth to 20-30 babies every month.
These roaches do best at temps of 85-100F to reproduce. They can survive at temps lower, but reproduction will either be slower or halted completely. If these do happen to get loose you can feel safe as they will not infest a house unless you live in a very warm climate. These roaches and other species are illegal to ship to Florida to avoid infestation.
I keep my dubia in a medium to large size Rubbermaid tote with egg cartons to climb/hide in. They require no substrate. I feed mine a blend of ground up dog and cat food, sometimes mixing protein powder and Crested Gecko diet in as well. They enjoy fruits and vegetables but make sure to remove all uneaten pieces as moldy produce can wipe out a colony of roaches. I water mine with rehydrated polymer crystals that can be bought at any hardware store in the plant section, just make sure they don't contain any pesticides. The brand I buy is SoilMoist. You can also order it online at watersorb.com.
The best way to keep them warm is by under tank heater or flexwatt heat tape (which should be regulated by thermostat). Do not use heat lamps as these guys stress and scatter under light. They do best if kept in a dark place.
