Mealworms are a popular feeder insect for bearded dragons, bluebirds, chickens, fish, and many other animals. They are high in protein and fat and are easy to maintain. They are available live or pre-killed and dried.
Live mealworms can be stored in a refrigerator for months. All you have to do is take them out of the refrigerator about once a week and give them some food for a few hours.
