Care & Wellness:

Although most people don’t want to see one roach, our keepers maintain a large breeding colony that requires daily attention. Every day keepers are on the lookout for unusual behaviors and feed them a wide variety of fruits, vegetables, and animal protein. 

  • They live in colonies, but males may defend small territories.
  • Hissing sounds are used in courtship routines and as a defense mechanism. Sound is produced by pushing air out of tiny holes on the side of the body.
