“The brown marmorated stink bug is more likely to invade homes in the fall than others in the family. The brown marmorated stink bug survives the winter as an adult by entering houses and structures when fall evenings start to turn cold. Adults can live for several years and look for buildings to overwinter in that shield them from the elements. They will work their way under siding, into soffits, around window and door frames, under roof shingles and into any crawl space or attic vent which has openings big enough to fit through. Once inside the house they will go into a state of hibernation where they wait for winter to pass, but often the warmth inside the house causes them to become active, especially in winter months, and they will fly clumsily around light fixtures.”
