Aphids are soft-bodied, pear-shaped pests that eat the sap in leaves and stems, causing the foliage to become dry. As aphids feast on plants, they leave behind a honeydew substance that attracts ants. The honeydew also allows black mold to grow on the plant, which eventually dies. When you notice aphids on a plant, kill them using a homemade solution instead of purchasing chemical insecticides that can harm the environment.
Things You'll Need
- Garlic clove
- Food processor
- Cayenne pepper
- Spray bottle
Puree a garlic clove and small onion in a food processor.
Pour the chopped onion and garlic into a large bowl. Add 1 tsp. of cayenne pepper and 1 qt. of water.
Stir the mixture to combine the insect spray ingredients.
Let the ingredients steep in the water for at least an hour.
Line a colander with cheesecloth. Sit a bowl under the colander to catch the liquid. Strain the mixture through the cheesecloth.
Pour the homemade insecticide into a spray bottle.
Apply the insect spray to all infested parts of the plant. Don't forget about the undersides of leaves.
Store the spray in the refrigerator for up to a week. Spray the solution onto affected plants every other day until you kill the aphids.
