Trapping Snails, Slugs

Smart Solutions : Episode SSL-759 -- More Projects »
Master gardener Kate Karam explains how to get rid of slimy pests such as slugs and snails by setting homemade traps.

  • Snails and slugs (snails without their shells) are attracted to hostas, leafy green lettuce, dense ground cover and thick mulch. They are most active in the spring.

  • To keep snails at bay, try the barrier method: Surround plants with pennies (figure A). The copper reacts with their slime and gives a slight charge. Another option is to use sand or eggshells, which are uncomfortable for the snail to crawl over.

  • Try burying shredded screen at the edge of a planter (figure B). It makes it difficult for the snails to climb inside.

  • Bury a dish a ground level (figure C). Fill with grape juice and sprinkle with dry yeast. The snails will be attracted to the smell and will crawl in and drown. Place where it is warm, moist and shady. Change liquid fairly frequently and after it rains.

  • Pick them off by hand when you see them climbing a pot, or spray with 1/2 cup of salt dissolved in a quart of water.

  • Tape strips of aluminum foil around the base of citrus trees. They don't like the way the foil feels.

  • Place a sheet of plywood on top of two bricks that you've placed on the ground. The snails will be attracted to the shade during the day. Lift the board and place snails in a bowl of warm soapy water.
