superworms are one of the least expensive feeders available and are a good live worm feeder for reptiles, rodents, birds, and fish. These live superworms are high in protein, require little or no maintenance and have an excellent shelf life. They should not be considered the main diet for your exotics. Wait until the superworms have just shed (very light color) and then feed your smaller reptiles those 'Freshly-Shed' meal worms. This is when these worms have a lower amount of chitin (the hard outer shell) and this will help your pet in digesting them more easily, and avoid impacting, due the the hard exoskeleton.
