This one works surprisingly well although it has practically no “taste”.

  • Handful of spinach
  • Tablespoon of oatmeal
  • Tablespoon of peanut butter
  • Tablespoon of milk powder
  • One orange
  • Half a zucchini
  • Half a cup of water

The worms will eat the ends of the zucchini and a little of the orange peel.
