I have a large colony of dubias for 2 years now. I have alway s heated them in my 65 degree basement with a heat mat. I recently had a tub of them that i did not heat and they were fine. So, is it necessary to heat them or will they live and breed at 65 degrees?

. Also, Dubia breeding activity/roach production will respond inversely to lower temps. So a colony (all other parameters being equal) kept at 95F will produce more than one at 85F; and that one will do better than one at 75F
