Have any of you used Exo Terra Heat Cables for heating your dubia colony? I just started mine (in a large plastic bin) and I need to raise the heat. I have looked into the heating pads for backs/shoulders but I am hesitant to use it for something it was not made for. I would prefer to use this heat cable if I could get it to work. The temps in the room I currently have it in are approx. 68-72 F. Thanks for the help.
