I have an 80L tub that's about 12" deep and 24" long. I know I will need vermiculite for bedding, a saw to cut through most of the top, wiremesh and a glue gun to ventilate the container and some egg cartons. What else will I need for crickets? I think I'll need more containers but I don't know how big they should be. I have good food sources for them, the area they'll be kept in will be cooler (around 20°c at night) than the rest of the house so I need to figure out heating but don't know what to get. Should I get heat pads?
