Mealworms

Mealworms (Tenebrio molitor) are one of the most widely used feeder insect. They are a great source of protein for reptiles, small mammals, and wild birds (Bluebirds really enjoy them). They are even used for fishing. Mealworms can last for months when stored cooled (apox 45-53 degrees), suspending them in a dormant state. They do need to be removed from the cold and warmed up to room temperature once a week to eat and get the moisture they need.

To supply moisture, take them out in the evening and give them a slice of vegetable (carrot or potato) placed on the surface of the container. As the worms warm to room temperature, they will become more active. In the morning place them back into cold storage, making sure to remove the vegetable before placing them back into cold storage. Never place the worms in direct sunlight or heat. If you maintain the worms at room temperature, they quickly pupate and turn into beetles (use a larger container). Before feeding the worms to your animals, it's recommended to warm them up with a slice of vegetable (carrot or potato). If after giving the weekly vegetable you notice the bedding has sand like grit at the bottom of the cup, sift the worms (metal mesh cat litter sifter work great), add more bedding material, and place back into cold storage (don't freeze the worms as it will kill them).
