Mealworms are the larval stage of the Tenebrio molitor darkling beetle and serve as a favored food source for many small reptiles, amphibians, and arachnids, such as leopard geckos and tarantulas. Our pre-packaged mealworms offer a hassle-free option for enthusiasts seeking an easy-to-use alternative to bulk feeders, and are ideal for pet shops or resellers looking for a polished, ready-to-sell product. These large mealworms measure about 1" long.
