I tried (and failed) many times at consistently breeding crickets until I found a method that works very well for me. I'll buy 500-1000 large crickets for feeding and put them all in one tub. I leave them to gutload and hydrate for about a week, also giving them time to breed some. Then I separate about 100-150 females. (This is the hardest part, and takes some time to pick them out) and put them in a five gallon bucket with about two inches of moist peat mix (for the garden) on the whole bottom and some styrofoam egg cartons (styro so they don't soak up moisture) and bit of dry food in a dish. I'll also put about 10 males in, so they continue to breed with willing females, but not enough that they'll dig and eat a lot of eggs. After about two weeks, I remove the crickets and put them back in the main bin. Then pour the dirt into a Tupperware container, remoisten, and incubate at 80 degrees. Within two weeks there are always tens of thousand of pinheads crawling around. When they are finished hatching out I move the entire Tupperware from the incubator to a large Rubbermaid bin with a heat pad underneath. Put a strip of screen leading out of the Tupperware into the egg cartons, and when they've all migrated, remove Tupperware and reuse. This was about the tenth method I tried, and the only one that worked every time for me. Good luck!
