Superworms make excellent live feeders for any appropriately sized animal.
They are active but not too fast which makes them great feeders for animals that love to hunt and chase their prey.
The substrate the Superworms are kept in is pine shavings. This helps absorb some of the excess humidity and waste produced by the Superworms. Be sure the bedding is checked daily for mold, exoskeletons, perished insects, and any food you have provided.
Moisture can be provided by adding cut carrots, orange cubes, or fresh fruit and/or vegetables. (Not too much, or moisture will build up and cause the worms to perish.)
These worms should be stored at room temperature and kept dry at all times.
