Organic Pest Control
Pests may include weeds that you don't want in your garden, insects that eat the plants, or diseases that damage the plant or garden planter. Pesticide use, in addition to introducing hazardous chemicals into your environment, also are not very selective. They can kill the weeds, bugs, and disease organisms, as well as plants that you want to keep. Continuous use of pesticides can also harm your children and family members. Natural pest control methods are much less toxic to family members, and your local eco-system, and can be just as effective.
How can you manage your pest problem?
- Encouraging beneficial bugs and animals that eat the pests to live in or near your garden.
- Carefully destroy any nests you find and limit the number of places where they might build homes.
- Use companion planting - place plants that are insect-resistant beside plants that insects love. This will help protect the plants that are vulnerable.
- Apply insecticides to your lawn that are non-toxic to humans.
- Block the access of unwanted animals by putting up physical barriers such as nets or wire-covered frames.
- Kill pests using old-fashioned traps, or boiling water.
Aphid Problems
- There are many species of aphids, and they feed on all types of vegetation. They can usually be found on young leaves, new shoots, and twigs or branches. Many vegetables and fruit trees, as well as ornamental plants, are attacked. Aphid feeding often causes leaves to curl and become deformed.
- Remove aphids by splashing soapy water onto the affected plant, followed by cold clean water.
- Protect plants that are troubled by aphids by companion-planting them with orange nasturtiums, catnip and garlic.
- A single ladybug can eat 400 aphids in one week. Encourage the growth of ladybugs – they are your friends.
Ant Problems
- Ants are not much of a problem, but they will protect aphids (because they produce a sweet substance). Sprinkle the ground with bone meal to keep ants away, and plant vulnerable seedlings in sawn-off milk cartons for protection. Plant ant-deterrant Geraniums, Southernwood, and Pennyroyal plants near the aphids.
Birds
Green Tip:
When planning your garden, include trees and shrubs. Placed correctly, they can reduce the heating and cooling costs for your home.
- Birds are both a friend and a foe. Although they can make a mess of seedlings, they also eat a lot of common garden pests.
- Add a bird-bath to your garden so that you can enlist their help in pest control.
- Protect fruit and vegetables by hanging computer CDs in fruit trees to deter the birds from the fruit.
Caterpillars
- Caterpillars feed on leaves and young plant growth and, due to their huge appetites, are capable of massive damage to plants. Young caterpillars are unable to chew, so they graze on the underside of leaves but as they grow and learn to chew the damage they cause increases.
- Sprinkle finely ground pepper onto dampened plants that are threatened by caterpillars.
Flies
- Flies spread disease and vermin.
- They can be deterred by placing pots of basil, tansy, pyrethrum, and mint plants around the home and garden.
Mosquitoes
- Mosquito bites are irritating, and they can spread West Nile Virus.
- Drain still pools of water that may have gathered in pots, bins, or containers around the garden.
- Change the water in pet bowls and birdbaths twice a week.
- Ensure that all rain barrels have protective screens.
- Keep your pond pump or garden fountain running constantly. Keep native fish in the pond to prevent mosquitoes from breeding.
Slugs and Snails
- Slugs and snails damage seeds, seedlings, underground tubers, leaves and fruit. Damage to seedlings often results in the death of the plant leading to major losses.
- Slugs and snails have delicate bodies and don't like rough ground. Sprinkling lime or wood ash around garden beds will deter them.
- Use bark as a ground cover. They don't like crawling over bark.
- Salt can kill slugs and snails. Sprinkle salt over your garden beds.
- Leave partially-buried saucers of beer around your garden. They will drown in beer.
