UMass Extension Landscape Message June 21, 2013

Lacebugs on Shrubs are very active now. Inspect upper leaf surfaces for the classic yellow stippling feeding injury and then inspect the leaf undersides for the nymphs. Target insecticidal soap or horticultural oil sprays (summer rate) to leaf undersides. Systemic imidacloprid is also effective. Azalea, rhododendron, Japanese andromeda are common hosts, among others"
