Boxelder Bugs Indoors: Exclusion + Perimeter Spray

Maple Bugs = Boxelder Bugs

½″ dark gray/red bugs congregating on house in fall. They don’t breed indoors.

Seal entry: Caulk cracks, repair screens.
Perimeter spray (early fall): Pyrethroid (e.g., bifenthrin) on siding/eaves where they gather.
Wall voids/attic: Insecticidal dust if sealed poorly.
Vacuum indoor bugs; dispose outdoors.

Treat early fall when bugs first appear—later they’re less susceptible.
