In cold regions the bugs will be dormant through the winter as either adults hidden under crevices in the bark or in piles of fallen leaves, or as eggs laid within the tissues of the leaves of evergreen trees. In the spring eggs hatch, the new nymphs undergo several stages over about a 6 week period, and the winged adults appear. Several generations can be expected each year. They feed by means of a proboscis that is inserted into the leaves and fluids are removed. Extensive feeding leads to chlorosis and a general mottled or stippled look to the leaves, along with heavy accumulations of dark fecal droplets.
Lace bug infestations rarely cause actual damage to a plant, other than the unappealing look to the leaves from the feeding and fecal spots. If spraying is needed most insecticides can be effective, but must be applied thoroughly to the lower surfaces of the leaves. Horticultural oils, safer soaps, neem oil, or traditional residual insecticides all control lace bugs effectively. Because the eggs may be tucked into plant tissues they are protected from insecticides, and multiple treatments may be necessary.
