Monitor for Lace Bugs showing up over the next several weeks on broad-leaved evergreens such as Andromeda, Azalea and Rhododendron. Nymphs are black and covered with spines and feed on the undersides of the leaves. Black fecal spots mark the places where they have been feeding. Yellowing and stippling of the leaves are the most visible damage symptoms. Twig and branch die-back can occur, however, when infestations go untreated. Applications of horticultural oil and insecticidal soap are effective in managing lace bug infestations.
