Question/Topic: Insecticide home-made 
Answer/Pointer: Q: I used to have a formula to make an insecticide spray for shrubs using products from the kitchen. Do you happen to have one? A: The only home-made mixture that I've heard works was concocted by Don Short, extension service entomologist with the Institute of Food and Agricultural Sciences in Gainesville. Prepare a spray to control scale, whitefly, mites and similar pests on trees by adding the following to one gallon of water: 2 1/2 tablespoons mild dish detergent and 2 1/2 tablespoons vegetable cooking oil. Short said the mixture should be agitated during the spray process to keep the oil in solution. As with most pesticides, make sure the temperature is below 85 degrees during use and until the spray dries. Short also recommends making test sprays a few days before treatment on a portion of a plant to make sure your shrubs are not sensitive to products used in the mixture.
