Aphids and spider mites can be removed by adding liquid dish wash soap (1
teaspoon to a liter) and spray the trees leaves several times a season
(although once may do it). Just spraying the tree with a water hose
produces enough pressure to knock them off also. I use both methods on my
apple and plum trees.
