How can Boxelder Bugs be prevented from entering a building or a home?
Boxelder bugs usually enters homes or buildings during late fall and all throughout winter. They do this to hibernate and they are usually inactive during this period. While they do not bite humans or destroy plants at home, they can leave marks on walls and their excrement can be left in places where they stay. Even after the end of winter, some boxelder bugs would fail to go out from their hiding place. Owners can prevent the bugs from staying at their homes or buildings by repairing or changing the doors or windows. Close all places that have an entry point such as the opening for the water pipe or chords from any electric or phone lines. Doors should also be sealed at the sides and bottom to prevent bugs from entering through these slits. If houses use screens, they should inspect it or change the ones with holes.
