To eliminate box elder bugs, seal cracks and entry points around windows and doors, and use insecticidal sprays to target areas where they congregate. Vacuuming up bugs can also be effective indoors.

Box elder bugs often gather on sunny exterior walls and can enter homes through cracks and gaps. Sealing entry points and using insecticidal sprays in areas where they cluster will help control them. Inside the home, vacuuming is an effective method to remove them without using chemicals. For outdoor infestations, spraying with water or insecticide can reduce their numbers.
