Worms can eat up to half their weight in food every day. When feeding them, the smaller the food scraps the better because they break down faster. Worms can eat fruit, vegetables, paper, eggshells, bread, tea bags, coffee grounds, grains and pasta. Do not feed them salty foods, citrus fruits, onions, spicy foods, oils, pre-packaged foods with preservatives and dairy products. They can eat meat but it attracts rats, vermin and flies. Spread the food evenly over the worms. Don’t feed your worms every day, preferably every few days, when they’ve finished what you last fed them.
