This pest has been extremely common in many locations this year. They can cause defoliation of a number of fruit crops and can be especially devastating to young trees, so they need to be controlled to prevent losses. They also like to feed on most of the small fruits, early maturing varieties of apples, and stone fruits. Growers who are on a regular spray program will usually not need to add any additional insecticide products to the spray tank for control of Japanese beetles. Be sure to watch pre-harvest intervals with all your sprays.
