Little can be done to deal with aphids on tall trees as treatment is only likely to be successful if the entire plant is sprayed If chemical controls are used, they should be used only in a minimal and highly targeted manner.

The RHS believes that avoiding pests, diseases and weeds by good practice in cultivation methods, cultivar selection, garden hygiene and encouraging or introducing natural enemies, should be the first line of control. Providing shelters such as flower pots loosely stuffed with hay in trees can help increase numbers Research indicates that earwigs on fruit trees can reduce aphid numbers and on fruit trees they do not cause damage.A circular hole can sometimes be seen in the aphid's upper surface where the adult parasitoid wasp has emerged. If the parasitoid is found, it can be encouraged by limiting the use of pesticides It is fairly easy to recognise the parasite's presence, as parasitised aphids stop producing wax and become black. The parasitoid wasp can sometimes be found in gardens, particularly those where little pesticide spraying is done. They are eaten by some ladybirds, lacewings and hoverfly larvae, and they are also attacked by a parasitoid wasp called Aphelinus mali.

Woolly aphid has a number of natural enemies which help to keep it in check, although they are rarely effective enough to prevent damage occurring.

Encourage aphid predators in the garden.

Where possible tolerate populations of aphids, they form an important part of many food chains and can be part of a healthy garden ecosystem.

This is best done in spring or early summer before an extensive population has built up

On small trees with light populations, it is possible to control woolly aphid by scrubbing the aphid colonies with a stiff-bristled brush.

Pesticide treatments are likely to kill natural enemies and are only likely to be successful if the entire plant can be reached. Within pesticides the shorter persistence products (that are usually certified for organic growing) are likely to be less damaging to non-target wildlife than those with longer persistence and/or systemic action. When choosing management options you can minimise harm to non-target animals by starting with the methods in the non-pesticide control section and avoiding pesticides. Little can be done to deal with aphids on tall trees as treatment is only likely to be successful if the entire plant can be reached.
