Safer Methods for Pest Control
PHYSICAL METHODS OF PEST CONTROL
- Pick or wash bugs off plants.
- Use floating fabric row covers to keep pests off crop plants.
- Pull weeds by hand before they set seed.
- Mulch gardens to prevent weeds.
NON-TOXIC SUBSTANCES & HEAT
- Applying corn gluten meal to turf grass (in early spring and fall) will prevent germination of crabgrass and weeds.
- Kill weeds in driveways and walkways with a propane torch or boiling water.
- Sprinkle diatomaceous earth around foundations and entryways for non-toxic control of ants.
NON-TOXIC BAITS, TRAPS, LURES
- Trap whiteflies and aphids with yellow sticky cards, a very effective method since these insects are attracted to color.
- Slugs can be trapped with a saucer of beer placed at ground level.
Learn to identify the "good guys" and let these beneficial insects do their job.
- Lady beetles eat aphids, and green lacewing larvae feed on soft-bodied insects, mites, and insect eggs.
- Spined soldier bugs, spiders, predatory mites, and many nematodes are also beneficial "allies".
- Bacillus thuringiensis var. galleriae (BTg) is effective in controlling many beetle grubs including Japanese and Asian beetles
- Beneficial nematodes are effective in controlling all types of beetle grubs.
HORTICULTURAL OIL SPRAYS
- For control aphids, mites, scale insects, whiteflies and other pests.
USE CAUTION. These oils are non-selective and will kill beneficial insects.
- Effective against whiteflies, aphids, mites, and thrips.
TAKE CAUTION not to use insecticidal soaps on butterfly caterpillars.Also, many plants are sensitive to
- Many naturally occurring plant extracts have insecticidal properties. They vary in toxicity to humans and non-target
organisms. USE THESE WITH CAUTION. Immature insects, including beneficials like butterfly caterpillars, are
extremely sensitive to extracts like Neem.
NOTE: With any insecticide, it is important to apply when pollinators (bees, butterflies) are not active and
where flowers are not present.
NEVER USE BROAD SPECTRUM INSECTICIDES
