A scale capable of infesting several kinds of ornamental shrubs, including pachysandra and bittersweet, but most often a serious pest on Euonymus. Heavy infestations can cause severe stress and dieback to the plant, or lead to the death of the plant. Mature females overwinter, deposit eggs beneath their wax shell in the early spring, and crawlers emerge in mid spring. This first generation completes development by early summer, and a second generation is common that is active until the early fall. In mild climates there may be 3 generations per year.
For ornamentals dormant or summer oils may be effective in killing the scales, as well as contact insecticides applied when the first instar crawlers are present. An IGR applied when crawlers are present also may be effective. A systemic applied to the soil can also provide effectiveness in killing the feeding scales.
