"A 2% soap solution is the quickest & best aphid control. This would
be about two ounces of dishwashing detergent per gallon of water, in a
sprayer. There is no extra "oomph" from paying extra for special
insecticidal soap where aphids are concerned, dishwishing detergent is
fine. Drench the tree especially the undersides of leaves. Once is
usually enough but at most a second time two weeks later. "

I read somewhere that ladybugs (which are available in shops in the
UK) and some other insects eat them and that ants rear aphids.
Might deter them in the long term.


Where even small trees are concerned, the idea of spraying is kill
overwintering eggs, which are present on the bark, not adult aphids.
With no foliage on the tree this is easier to achieve, but needs to
be done thoroughly. Tar oil winter wash - a weak creosote solution
used to be the standard remedy but is no longer available. A bit of
research might suggest possible alternatives for those who didn't
lay in a stock in time.
