Im breeding hissers and crickets. How do you all heat?, the thing is I will have 1 bin for hissers 1 for adult crickets 1 for small crickets and like 1 for the eggs to hatch in. So this is like 4-5 bins and I use human heating pads. I dont want to have to have 4-5 heat pads going. Is this how you guys do it or do you have a better way? Your help will be appreciated.
