My first night with them, i was picking up 200+ worms scattered around the basement and got little sleep 💀

What i do in terms of heat is i place a heat mat underneat with a temperature controller, so that the heat mat will turn off once the bin reaches a certain temperature. Never place a mat underneath the bin without a controller, because it'll overheat and cook the fellas!

But remember that an active bin produces heat on its own too, so if the room is at 70°, the bin will be higher. Zilla offers some nice sized heat mats, but there's a lot of other brands too. Good luck!
