Slug Trap — or "Beer Garden" 

Beer or Yeast Mixture:

  • 2 tablespoons flour 
  • 1/2 teaspoon baker’s yeast 
  • 1 teaspoon sugar 
  • 2 cups warm water  

Cut several 1-inch square openings in the sides of a clean covered cottage cheese container or margarine tub.  Sink the container into the soil so the openings are just above the soil surface. Remove the lid and pour in 1/2-inch of beer, or use the yeast mixture above. Slugs will be attracted to the trap, fall in and drown. Empty the container every few days and refill.
