They invaded WV several years ago, and yes, they are among the most disgusting pests, right along with the Lady Beetles that the govt. imported from China, years ago on the assumption that they were the beneficial Lady Bugs that eat aphids. Well, they are no kin to the "nice' Lady Bugs and they are horrid pests and if you were to ask me which "stinks" the worst, I would say the Lady Beetles, but the Stinkbugs are not far behind and they have started to appear from the attic and wherever they were hiding all winter and plague me.
