Spraying with insecticide concentrates is one of the best overall methods for treating lawns and plants for insects. The liquids will cling to the leaves of the plant where you want it.There are liquid and powdered concentrates available for a wide variety of uses. These products are typically applied with a pump up garden sprayer, a back pack sprayer, or a hose-end sprayer. In most cases the use of a spreader sticker will help the insecticide stick to the leaves and give far better results. Remember to always read and follow the label directions for the product.
