In spring, transfer the cocoons from the refrigerator or small overwintering cages to emergence cages that are large enough to provide plenty of room for the moths to expand their wings. Do not disturb the moths until their wings have fully expanded and hardened. In large cages, the moths will mate and the females lay eggs and you can rear them through another cycle if you want. 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.
