In its native countries the BMSB is a pest of fruit trees such as apple, peach, persimmon, and fig, but it is new enough to North America that its impact is still unknown. It is, however, fast becoming a tenacious pest within structures, where the adults over-winter in potentially large numbers. They do not breed indoors and do not cause damage, but their presence and the strong odor they emit are unpleasant. Adults emerge in mid spring to lay eggs on host plants, with egg laying continuing into mid summer. Nymphs undergo 5 instars in the summer, with 2 or more generations possible each year.
Since the impact so far is their presence inside structures, management begins with the attempt to locate and close all potential entry points from the outside. Permanent exclusion will prevent the need for constant applications of pesticides, which are likely to have only moderate success against these large insects. Exposed bugs can be vacuumed for removal.
