Only a few basics need be followed to start and maintain a mealworm colony for a constant supply. In addition to bluebirds, mealworms will attract a wide variety of popular bird feeder visitors. The Midwest birds listed below LOVE mealworms and may even have a preference for them over and above black sunflower seed. In other geographical areas an even greater variety of birds will be attracted to mealworms. I get mine from Rainbow Mealworms P.O. Box 4907,126 E. Spruce St., Compton, CA 90220.

A 5-gallon plastic pail works well. Buy enough oat bran to fill half the pail. Oat bran is usually available in large food stores, food co-ops or feed stores. A year's supply will be only a few dollars. When received your mealworms will be packed in crumbled newspaper.
