The red wiggler worms have a great appetite that will allow them to eat half of their body weight a day. Therefore, careful monitoring of the bin is necessary. The worms do not eat fats, dairy, meats or animal wastes. They do eat paper (non-glossy), fruit and vegetable scraps, yard waste and organic matter. All food shall be placed deep enough within the bedding to prevent fruit fly population. Bins should be covered to prevent flies also. Once the food is placed within the bin, bedding shall be placed over the food. The bin should be well ventilated and shall be kept out of direct sunlight. Once the food has disappeared (or digested by the worms) more food may be added.
