At On Your Mark Pest Control, our exterior boxelder bug service is designed to stop large seasonal invasions before they enter your home or cottage. Boxelder bugs commonly gather on sunny exterior walls in late summer and fall, especially on south- and west-facing sides, as they search for cracks and gaps around siding, window frames, soffits, and foundations. Our service includes a detailed exterior inspection followed by the application of a professional-grade residual treatment to key landing and entry areas. This preventative barrier targets boxelder bugs where they congregate, significantly reducing the number that make their way indoors to overwinter. By focusing on early-season prevention, we help keep your property free from staining, unpleasant odors, and nuisance infestations.
