It's not required since it's a systemic insecticide which means it absorbs into the plant. Scale feed within the plant tissue and their exposed side doesn't allow penetration of insecticide. Since the insecticide is inside of the plant, it's very effective with scale while protectant (aren't absorbed by the plant) insecticides don't work well if at all.
