We are the largest mealworm farm in America - we've been in Compton since 1956.  Our worms are fed human quality bran, carrots, and cactus.  

The castings (worm poop!) are a dry and odorless soil amendment we sell to local gardeners.  You can sprinkle it onto plants or mix it with water for a tea.
