Cold and feeder problem

They can't breed without high temeratures, I believe that they can only breed in temperatures over 75 F and they can't live below 65 F

Dubias will live through anything that doesn't freeze them solid. My house is COLD in the winter. 50 - 60 degrees usually, sometimes dropping close to 40. The roaches usually have heat, but sometimes I turn it off and they pretty much stay dormant. They don't grow or breed without heat, but they'll live through it.
