These are one of the most popular feeder roaches in the hobby, and, quite attractive, too. With a wide range in size, from about 3/16” up to 2”, one can feed their entire collection, with the exception of the smaller slings. They give live birth and grow quickly. Give them plenty of heat, 85 to 95 degrees, some fresh fruits and vegetables, dog and/or cat food, and you will not buy another smelly, dirty, mite-infested cricket again. Crickets?, you don’t need no stinkin’ crickets!
