Brown Marmorated Stink Bug

Brown Marmorated Stink Bug (Halyomorpha halys)

Brown marmorated stink bugs (Halyomorpha halys) are an invasive and difficult to manage pest species that were first identified in Allentown, Pennsylvania in 2001 - although they had probably arrived here several years earlier - and it is thought that they first came to the United States in shipping containers arriving from Asia.  

Besides its pungent odor, the brown marmorated stink bug is most notorious for having become an annual nuisance for home owners for its habit of gathering in large numbers on the sides of houses and buildings in the late fall, and entering these structures in order to survive the winter.
