Hatching usually begins in February and March, that is when to start looking on the under side of the leaf for activity or for stippling on the upper surface. Inspect the plant and be sure of the identification of the pest. If you are not sure of the identification take it to your Extension Service office before attempting chemical control. Otherwise you may be using the incorrect control and wasting money. Lace bugs usually don't harm their host plants that are in heavily shaded areas.
Lace bugs seem to prefer bright, sunny areas so plant susceptible plants in shady areas.
To preserve the natural predators use the least harmful control methods possible until the predators take over. For the best control, time applications to start when the first generation is present and make sure the undersides of the leaves are covered. Early treatment may reduce the amount of control effort required. If the lace bug population is small and little or no damage is apparent, wash the bugs off with a strong water spray from a garden hose. When the infestation is light and water doesn't seem to work then try using an insecticidal soap as the first step in chemical control.
