What You Can Do

Garden and Lawn Pesticides and Alternatives
  • Insects such as spider mites, aphids and mealy bugs can be removed from your plants, bushes and trees by hosing them off with a strong burst of water.
  • Wearing garden gloves pick off small insects such as lilac leaf miners, leaf rollers, Colorado potato beetles, and spruce budworms. This is best done early in the morning. Pick forest tent caterpillar larvae off your plants when they cluster together on cool days or in the late evening. Remove eggs or cocoons from other species in the same manner.
  • Dig out weeds by hand.
  • Keep cutworms away from your tomatoes, peas, cabbages, and beans by removing both ends of a can and sinking it around the bedding plants, or by placing aluminum foil around the base of the plants.
  • Hoe your garden regularly to control weeds and keep plants healthier.
  • If you don't want to let bugs move in, keep old bags, decaying vegetables and other rubbish out of your yard because they can provide homes for insects. Old tires often provide breeding places for mosquitoes.
  • Get rid of slugs by placing flat boards near your plants. Later, lift the boards and destroy the slugs that have gathered there to avoid the sunlight.
  • Plant marigolds, chrysanthemums, chives, onions, garlic, basil, savory, horseradish, mint, thyme and the like among and near your garden plants because their natural odours and root secretions repel some insects.
  • Insecticidal soaps can be used to dislodge or suffocate insects.
  • If you feel that pesticides are required, use degradable natural products such as Bacillus thuringiensis (Bt). (The labels usually say "thuricide" or "biological insecticide.")
  • Put bird feeders and bird houses in your yard; birds are a natural form of insect control.
  • Invite toads into your vegetable patch by building a "toad house", such as an old terra cotta pot with an opening in the side, or a small pile of rocks with an opening.

Have you considered…
Scattering onions throughout your garden instead of planting them in rows, so that root maggots cannot travel easily from plant to plant?


Rotate the species of vegetables and flowers in your garden from year to year, or at least rotate the same species between locations, to discourage soil diseases and insects.
