Granular Imidacloprid is a systemic (spread udner a plant & watered in) and as a contact product sprayed on the affected plant and has worked well for me on my fruit trees and some ornamentals in my yard.
Imidacloprid interrupts the ability of insects like aphids, scales, and mealiebugs to properly mature which causes them to be unable to reproduce.
It's not toxic to mammals/humans if if used as directed altho is is toxc to honeybees, so it is important wait to use it until after your plant has finished flowering.
