Pest description and damage Brown soft scale are flat, yellowish to dark brown, somewhat mottled insects. They are found mainly on twigs, although young scale also may be found on the foliage, typically on the underside of leaves and along veins. Scale suck plant sap and produce copious honeydew on which sooty mold may grow. Brown soft scale has a wide host range. There are multiple generations per year.
There are numerous parasitoids that often control this scale if left alone. Occasionally an outbreak occurs, but at that point it is likely that the parasitoids will easily find it and the population will crash.
