Superworms should be kept in a well-ventilated smooth plastic container (e.g. cat litter box or wash basin), with 1-2 inches of worm chow covering the bottom. The chow serves as both their food source and bedding, so once it becomes sandy in appearance, be sure to add more. For hydration, add small pieces of raw potato, carrot, or celery. Replace these every 2 days or if you see signs of mold.
Superworms prefer to stay buried, so there is little danger in them escaping, but we recommend that the sides of the container be smooth anyway. Keeping the container open is ideal, but if you have to use a lid (due to animals or small children), please make sure it is well-ventilated. When using a lid, check your container regularly for excess condensation, as this can lead to mold growth.
Do not refrigerate Superworms, it will kill them. They should be kept at room temperature (ideally around 78 F).
Their shelf life is approximately four months.
