Spider Mites

Mites damage leaves and fruit by feeding on leaves. This feeding causes color changes, markings, and plants to drop their leaves. Heavy infestation can leave fine silk webbing over the branches and leaves. The reduction of healthy leaves can interfere with photosynthesis, causing a loss of plant vitality. The majority of spider mite species overwinter as eggs on host plants. Mites become active in the spring and can have up to 10 overlapping generations per year.

It is possible to check the leaves for mites or eggs. The Pacific Northwest’s Insect Management guide recommends hitting a branch over a white piece of paper to see if mites are present. Mites can be biologically controlled using predator insects like lady beetle, lacewing or thrips. Spray applications require thorough coverage and usually two or more applications are required.
