At this point in time we cannot offer a control for woolly aphid as there isn't a product in our range registered for this pest. Woolly aphid generally attacks apple trees and occasionally pears which leads me to believe the pest on your lime tree is unlikely to be woolly aphid but could possibly be mealy bug or scale. Both insects are sap sucking and can be controlled with PestOil .
