Mealworms (Tenebrio molitor) – Mealworms are an attractive food item for many species of animals. Amphibians, birds, fish, reptiles, and small mammals all go crazy for them. GLH mealworms are a step above the rest! No beneficial mealworm could be raised just on bran. That's why GLH mealworms are supplemented with a high protein (25%) diet that gives our mealworms a little extra boost! Your animals will thank you for it!
