Hey I am planning on starting a dubia colony. Except my house is pretty cold, the area they are staying in is in the low 60s to high 50s (F) at worst. I have an under tank heat pad that I can use to warm them, but I'm not sure if it's ok to put on a rubbermaid. I was reading a thread on here and someone said that they don't have a problem with it, and some said they don't use any additional heating. Can my roaches sustain themselves at the temperature of my house?
