Mealworms (Tenebrio molitor) are a commonly used feeder insect for reptiles, amphibians, birds, and small mammals. Their manageable size and availability make them a convenient feeder for many insect-eating animals.

Mealworms provide a source of protein and fat and are often offered to reptiles such as leopard geckos, bearded dragons, small skinks, and many other insectivorous species. They are also frequently used for amphibians and small insect-eating animals.

Because mealworms have a tougher outer exoskeleton compared to some other feeder insects, they are often best suited for reptiles capable of handling slightly firmer prey items. Younger reptiles may benefit from smaller insects such as crickets or other softer-bodied feeders.

Mealworms can be gut loaded before feeding to improve their nutritional value. Dusting with calcium or vitamin supplements is commonly recommended depending on the dietary needs of the reptile being fed.

At Caliber Exotic Supply, feeder insects are selected for quality and consistency to help ensure dependable feeding responses.

Mealworms can be stored in a ventilated container with bran or oats as bedding. Small pieces of vegetables such as carrot or potato may be provided for moisture and gut loading.

To help prevent mealworms from burrowing into enclosure substrate, they can be offered in a smooth-sided feeding dish or using feeding tongs.
