Use non-chemical controls. They are the least-hazardous methods.
- A forceful water spray will knock aphids off plant leaves. It works just as well as a pesticide.
- Sticky tape can keep root weevils from climbing up your rhododendrons.
- Traps are effective against wasps, moths and whiteflies.
Use biological controls. "Good bugs" are beneficial insects that do the dirty work for you.
- Lacewings, ladybugs and dragonflies are voracious predators.
- Bacillus thuringiensis (Bt) is a naturally-occurring bacterium that produces a caterpillar-killing toxin.
- Beneficial nematodes are tiny worms that control root weevils, crane flies and other pests that live in the soil.
- These good bugs are already in your yard if you avoid pesticides and use Natural Yard Care techniques. They can also be purchased and released.
Use pesticides only as a last resort.
- Pesticides are designed to kill things and pose varying risks to people, pets and beneficial insects.
- Pesticides can lead to even more pests because pest populations bounce back more quickly than the beneficial insects.
- Smart spot-spraying targets just the problem and keeps pesticide use to small amounts.
