Homeowners usually are more concerned with kudzu bugs because of their overwintering habits similar to boxelder bugs, cluster flies and Asian multicolored lady beetles. During the warm summer months, people do not see the bugs. Once fall temperatures start dropping, kudzu bugs congregate in massive numbers on sun-exposed surfaces to warm themselves.
Next they locate sheltered voids, cracks and crevices to survive the winter, which can include people’s homes. Once indoors, they do not feed or reproduce. They are dormant during the winter, unless there is a warm day, and will vacate the building with the warmth of the spring.
