Juniper Scale

Carulapsis juniperi

Juniper scales have white oval females with a distinct yellow spot in the center. (See photo) The males are elongated. All plant parts are attacked, but scales feeding on the leaves and leaf stems are noticeable. Loss of vigor and ultimately plant death can occur. Honeydew produces will result in sooty mold on the shrubs.

Treatment of heavily infested shrubs should take place in late spring to early Summer when the immature crawler stage is present. They resemble tiny aphids. The crawlers molt into mature scales which are harder to manage.The adult females produce eggs within Their body and over winter filled with eggs. Oil sprays in early spring are effective but may burn the foliage.
