You can sell surplus crickets from your rearing operation to fishbait stores. Field crickets normally live outdoors, and you can find them under rocks or boards. House crickets live in buildings and are straw-colored. If you can't find these crickets, you can buy them from fishbait stores or biological supply houses. When collecting crickets, make sure you get both sexes.
Females are the ones with a long, thin egg-laying tube at the end of the body.
Crickets need more rearing space than most other insects. Have your rearing set-up ready to go before you get your crickets. You will need a large container such as a garbage can, pickle crock, metal-lined box, large lard can or wash tub. The container should be about 2 feet deep and the bottom about 15 x 15 inches. Containers this size will support about 200 crickets.
