They are insects so they won't work for composting but they do work great for frass production for gardens. Many places people do eat them but we raise them as feeders for chickens or pet reptiles, fish etc. They do work fantastic for pan fishing. Superworms are just larger then mealworms being a little more meaty instead of just mostly a shell that can be harder to digest for pets or livestock. Great protein source. Thanks for the resteem.
