LF Superworms are grown and packaged by hand in Fort Collins, CO. They are available in three different container weights: 25, 50, and 100 grams. Each weight is guaranteed to have at least as many worms as grams, and usually more. Each container comes with bedding, food, and worms. The worms we provide are the larvae of the darkling beetle and are at the largest stage of their larval life. If you'd prefer smaller worms for smaller critters, let us know!
