Boxelder Bug Control in Southeast Michigan

Boxelder bugs are a familiar fall nuisance in Southeast Michigan. They spend the summer feeding on boxelder, maple, and ash trees, then migrate to buildings in large numbers in the fall to find overwintering sites. They congregate on south and west-facing exterior walls and find their way indoors through gaps around windows, doors, and siding.

Identification

Michigan has several species that fall under this pest category. Here is what to look for.

Appearance

Black with distinctive red-orange markings along the edges of the wings. Flat, oval-shaped, about 12mm long.

Season

Most visible in late summer and fall when they aggregate on warm exterior surfaces. Can appear inside in large numbers during fall and winter.

Damage

Boxelder bugs do not bite or sting and cause no structural damage. Their feces can stain fabrics and surfaces.

How We Treat

Exterior perimeter treatments in late summer and fall are the most effective approach. Treating aggregations on exterior walls before they enter the structure reduces the number that overwinter indoors. Interior treatments address bugs that have already made it inside.

FAQ

Why do I suddenly have hundreds of boxelder bugs?

Boxelder bugs aggregate in large numbers in the fall as temperatures drop. They are looking for overwintering sites and are attracted to warm, south-facing surfaces. The sudden appearance of large numbers is normal seasonal behavior.

Should I seal up my house?

Yes. Sealing gaps around windows, doors, utility penetrations, and siding reduces the number that can enter. This is a helpful long-term preventive step alongside treatment.

Will they come back next year?

Boxelder bugs are a recurring seasonal pest wherever host trees are present. A service plan with fall treatments helps manage populations year over year.
