How to Kill Aphids on Green Plants

Aphids are small plant-eating insects and are considered one of the most destructive garden pests. Although they are tiny, they can quickly become a big problem. Aphids feed on your green plants; left unchecked, they can cause serious damage and even kill your plants. Follow a few simple practices to rid your plants of aphids.

Things You'll Need

• Ladybugs
• 2 tsp dishwasher soap
• 1 quart water
• Spray bottle
• Garlic plants or cloves

Instructions

1. Release ladybugs into your plants. Ladybugs feast on aphids. Quantities of ladybugs can be purchased from garden centers. They must be released in the evening, and they will fly away if it rains, so you should plan your ladybug release accordingly.

2. Apply insecticide spray. A non-toxic solution can be made with dishwasher soap and water. Mix in a bottle and spray on plants. This solution dehydrates and kills aphids. Apply weekly. When spraying, pay special attention to the undersides of leaves, as this is where aphids and their larvae will reside.

3. Plant garlic nearby in the spring. Aphids are repelled by garlic. As the garlic grows, it will deter the aphids from taking up residence in your plants. You can also rub plants with cut cloves of garlic.

Tips & Warnings

• Chemical insecticides should be avoided. They will kill aphids, but may damage your plants. Some chemicals also kill beneficial insects, increasing your plants' risk of future infestations.
