'Stephanitis pyrioides' is the binomial, Latin or scientific name of the Azalea lace bug. It's a voracious sapsucker as a spiny, wingless larvae or as a brownish, clear-winged adult. Its feeding frenzy begins in May, which is the most important time to treat.
Particularly effective controls are pesticides with the active ingredients of acephate or carbaryl. They must be applied in such a way as to cover the undersides thoroughly. They may be applied at three-week intervals until the Azalea lacebug numbers have been slowed.
