Box Elder bugs will be starting to swarm on the sides of buildings soon! If you notice clusters of them on the south or west side of your building, they may start to move indoors when the weather cools down. As fall and winter near, they will start migrating indoors to overwinter. They won’t do damage to your home or people, but they will stain curtains and light colored siding and produce a foul smell when crushed!
