So I recently started trying to breed crickets and I've got everything set up, vermiculite as the substrate, and I used organic top soil that strangely has mulch and sand in it too in two sandwich containers, food, water, egg crate pieces scattered around and a 50 watt heat bulb about 12 inches above the floor of the container which should provide about 75 degrees. I keep finding dead crickets and no eggs...this project has been going for about a week now and still nothing. I dont understand whats wrong...
