Every fall, thousands of shield-shaped brown marmorated stink bugs swarm Michigan homes looking for warmth. Our fall exclusion system stops them before they get inside — and eliminates the ones already there.
Brown marmorated stink bugs (BMSBs) are invasive insects originally from Asia that have become one of Michigan's most annoying fall pests. They are about the size of a dime, shield-shaped, and mottled brown with distinctive banding on their antennae and abdomen edges.
Their most infamous trait is the foul odor they release from glands on their thorax when disturbed or crushed — a smell often compared to cilantro or burnt rubber. They do not bite or damage your home structurally, but their sheer numbers and stench make them a nightmare for Michigan homeowners every autumn.
Large groups of shield-shaped bugs gathering on sunny, south-facing walls of your home — especially in September and October.
Finding stink bugs on curtains, lampshades, or windows inside your home — especially on warm winter days when they emerge from hiding.
A strong, unpleasant smell when vacuuming, moving furniture, or in rooms where stink bugs have been crushed or disturbed.
Finding dead stink bugs accumulating in ceiling lights, window sills, and between window screens and glass.
Hearing loud buzzing as stink bugs fly clumsily around rooms, often bumping into walls and windows as they search for light.
Yellowish-brown stains on curtains, walls, or fabrics where stink bugs have been resting or have been accidentally crushed.
Michigan's dramatic temperature swings in fall create the perfect trigger for stink bug invasions. As daytime temperatures stay warm but nights dip into the 40s and 50s, stink bugs begin their mass migration toward heated structures.
Our state's abundant agriculture — especially fruit orchards and soybean fields — provides ideal summer feeding grounds for brown marmorated stink bugs. By fall, populations are enormous and looking for somewhere warm to spend the winter.
Michigan's older housing stock with lap siding, double-hung windows, and stone foundations provides countless entry points. South-facing walls absorb solar heat and act as gathering spots where hundreds of stink bugs congregate before squeezing inside. Once one finds a way in, it releases pheromones that guide the rest.
We don't just kill the bugs you see — our complete exclusion system seals your home and prevents future invasions before they start.
We thoroughly inspect your home's exterior — especially south-facing walls, window frames, soffits, and utility penetrations — to identify every crack and gap stink bugs use to get inside.
We apply targeted treatments to eliminate stink bugs already inside your home and on exterior surfaces. Our products are family-safe and specifically effective against stink bugs without the odor release caused by crushing them.
We seal entry points and install a protective perimeter barrier around your home that repels stink bugs before they can congregate. Best applied in late summer before the fall invasion begins.
Fully licensed Michigan pest control professionals with comprehensive insurance coverage for your peace of mind.
We use stink bug-specific methods that eliminate them without triggering their defensive odor — no smell, no stains.
All treatments are EPA-approved and safe for your children and pets. We protect your family while eliminating pests.
We time our treatments for maximum effectiveness — treating before fall invasion season to keep stink bugs out all year.
Brown marmorated stink bugs seek warm shelter as temperatures drop in September and October. They are attracted to south-facing walls that absorb sunlight, and they squeeze through tiny cracks around windows, doors, siding, and utility pipes to overwinter inside your walls and attic. Once inside, they release pheromones that attract hundreds more.
Stink bugs are not dangerous — they do not bite, sting, or spread disease. However, when crushed or disturbed they release a foul-smelling chemical that can stain fabrics, walls, and surfaces. In large numbers they become a serious nuisance and can trigger allergic reactions in sensitive individuals.
Crushing a stink bug releases a pungent odor from defensive glands on their abdomen. This smell is extremely difficult to remove from fabrics and surfaces, and it can actually attract more stink bugs to the area. Instead, vacuum them up (dispose of the bag immediately) or contact a professional for proper removal.
Stink bugs are most active outdoors from May through September, feeding on fruits and vegetables. The major home invasion season is September through November when they seek overwintering shelter. They may also become active inside homes on warm winter days, emerging from walls and attics confused by the warmth.
Professional exclusion is the most effective prevention. This includes sealing cracks around windows, doors, siding, and utility entries, plus applying a protective perimeter barrier before fall. DIY methods like caulking help but rarely cover all entry points. Our fall exclusion service creates a complete defense before stink bug season begins.
