Garlic oil spray is a homemade pest spray that is natural, safe and effective. To make garlic oil spray, put 3 or 4 cloves of minced garlic into 2 teaspoons of mineral oil and let the mixture sit overnight for about 8 hours. Strain the garlic out of the mixture and add 1 pint of water and 1 teaspoon of dish soap. Store the spray in a jar and dilute it before use by adding 2 teaspoons of the garlic oil to 1 pint of water. Garlic oil spray is useful for pests such as aphids and flea beetles.

Hot pepper spray is made by combining 2 tablespoons of hot pepper sauce, 1 quart of water and a few drops of dish soap. Let the mixture sit overnight. The compound capsaicin in hot peppers gives the spray a hot, spicy aroma that repels insects, especially mites and whiteflies.

Tomato leaves are poisonous to many insects because they contain alkaloids. To make tomato leaf spray, soak 1 or 2 cups of chopped tomato leaves in 2 cups of water and let the mixture sit overnight. Strain the tomato leaves out of the mixture and add another 1 or 2 cups of water to complete the spray.
