Great Feeder for Picky eaters! They cant get enough of them, watch your critter come alive! Lobster roaches are one of the easiest feeder roaches to keep and breed. Unlike crickets, roach enclosures do not smell and can be kept clean with a little attention to housekeeping. Lobster roaches make exceptional feeder insects. They grow up to one and a quarter inches as adults, making them only slightly larger at maturity than adult crickets. Lobster roaches are soft bodied roaches, their exoskeleton is thinner than many other kinds of roaches, making them a high meat to shell ratio feeder. Lobster roaches have wings but can not fly. Even the most finicky of reptiles love them.
