Homemade Pesticide spray recipe. 1 quart water 3 ounces strong onion, peeled 2 ounces fresh garlic 2 tobacco cigarettes (remove paper) 1/8 teaspoon dish washing detergent 4 ounces denatured alcohol 2 tablespoons buttermilk 1 Teaspoon Dr. Bronners Peppermint soap The onion, garlic tobacco and water are mixed in a blender until liquefied. Then the mash is cooked until simmering. It is cooled to luke warm. Then the soap, detergent, alcohol and buttermilk are added. The liquid is poured through a fine mesh strainer. The plants are sprayed or dipped. Most of the pests hang around the underside of the leaves. Special care is taken to reach these sections. The spray is used every two or three days. Keep out of the reach of children and pets as the nicotine leached from the tobacco is highly toxic. -H4
