Insecticides are horticultural chemicals used to kill insects or prevent insect infestation in trees, shrubs or any other plant. Some insecticides are meant for general use, while others specifically target a certain insect species or are made to protect a specific tree species. Before you purchase an insecticide for spraying, identify the tree and insect species so you purchase the most effective spray. Does this Spark an idea?
Instructions
1. Read all the directions on the insecticide label before you begin spraying, including the safety procedures. Put on protective gloves and goggles before you begin spraying.
2. Fill a 3-gallon garden sprayer reservoir with the insecticide. Dilute it with water, if the instructions require you to do so. Do not begin the process of spraying if the weatherman forecasts rain that day. Begin the process on a still day, so the wind does not transport the insecticide to other plants.
3. Spray the entire circumference of the trunk of the tree, starting at the ground and working your way up to the lowest branches. Walk slowly around the tree as you spray, overlapping the layers by 1/2 inch.
4. Spray the branches and foliage in layers. Start with the lowest branch layer. Move the branches down with one hand so you can begin spraying the branch where it meets the trunk. Move the spray out along the branch, all the way to the tip. Repeat this along the entire circumference of the tree.
5. Move up to the next layer of branches, spraying the trunk between the branch layers, as well. Apply the spray to the branches and foliage in the same manner you applied it to the lowest branches. Continue all the way to the top of the tree.
6. Let the insecticide air dry.
