Make your own organic pesticides using natural ingredients such as salt, citrus oils, cayenne pepper, onions and garlic. Mixing one or a combination of these ingredients with water and spraying them onto affected areas works as a pesticide.
For a salt pesticide, mix 2 tablespoons of Himalayan salt crystals with 1 gallon of warm water. Spray this on plants to stop spider mite infestations. To deal with an ant problem, mix 10 drops of citrus essential oil, 1 teaspoon of cayenne pepper and 1 cup of warm water. Spray directly on the problem area.
For another homemade pesticide, mince 1 organic garlic clove and 1 medium organic onion. Place the ingredients in 1 quart of water and wait one hour. Next, add 1 teaspoon of cayenne pepper and 1 tablespoon of liquid soap. Store in the refrigerator and use as a spray for up to one week.
