Elongate Hemlock Scale
The Elongate Hemlock Scale attaches itself to the underside of needles of hemlocks and feeds on the juices. Heavy infestations can weaken the tree and cause defoliation. It often occurs along with another serious pest, the Hemlock Woolly Adelgid. This “1-2 punch” will eventually kill the tree.
Like most scale insects, the elongate hemlock scale secretes a waxy coating which protects it from drying out, predators, and topical pesticide sprays. Fortunately, we have options to control this pest.
