Aphid and Mite Control
- 1 tablespoon soap
- 1 tablespoon vegetable oil
- 1 gallon water
Mix 1 tablespoon pure soap with 1 tablespoon vegetable oil in 1 gallon of water. Spray on aphid- or mite-infested plant parts. Store unused portion in labeled container. Use pure soap only as detergent can burn plants.
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.
- Wood chips
Sheet mulch weedy areas with layers of cardboard, wood chips, and compost. Learn more about sheet mulching.
- 3 tablespoons baking soda
- 2 teaspoons insecticidal soap or ultra-fine horticultural oil
- 1 gallon water
Mix 3 tablespoons baking soda with 2 teaspoons insecticidal soap or ultra-fine horticultural oil in 1 gallon of water. Spray on affected plant parts.
Attract "Nice Bugs"
Introduce friendly insects such as ladybugs (natural enemies of aphids), ground beetles and praying mantises, to rid your garden of uninvited pests. Check with a nursery for plants that attract these insects.
