Here's a good place to start. If you have all these basics covered, usually they can't be stopped. It's getting to that time of year when heat slows down breeding, so watch the daily high temps. I have a thermocube that kicks on at 78 to run a fan. Even so I may not keep the colony all summer. When it gets hot here in Los Angeles, all the fan does is blow the hot air around. Last year I brought them in the house on really hot days. This year I'm thinking of picking 1.2 and keeping them in the house all summer.
