Thoroughly spray so that all insects are covered. Be aware that many insects prefer the undersides of leaves or may be under sepals or leaf buds where they are hard to reach. Dormant treatments are ideal because, with leaves removed from trees, coverage is much more effective. A pressurized sprayer is required for application. Repeat applications will be required for pests migrating in or appearing after application. Precautions and Safety EquipmentMinimize your exposure to pesticides. Avoid contact with eyes. Wear eye protection, long pants, a long-sleeved shirt, and a hat that can be washed after each use. Always read label of individual product for additional directions. Always check the label before purchasing or applying a pesticide product for a specific pest on a specific plant to be sure it can be applied. Follow label directions precisely.
