Professional timed perimeter treatment and prevention. Don't let stink bugs take over your home this fall.
Every September, the same thing happens in Genoa homes. The temperatures start dropping. The south-facing walls of the house start warming up in the afternoon sun. And the brown marmorated stink bugs begin congregating — on the siding, around window frames, at every gap and seam they can find their way through.
By October, they're inside the walls. By November, they're finding their way into the living space. And if you disturb one — or worse, vacuum one — you already know what happens next.
Stink bug extermination in Genoa works best as prevention. Shahan Pest Control treats the exterior of your home before peak entry season so that the invasion that happens to your neighbors doesn't happen to you.
Brown marmorated stink bugs are not reproducing inside your home. They're not infesting it in the traditional sense. They're doing something more specific: they're seeking overwintering harborage.
As temperatures drop in late summer and fall, stink bugs follow warmth. The south and west-facing sides of structures in Genoa warm up significantly in afternoon sunlight — and the stink bugs aggregating there are instinctively seeking the heat differential that signals a protected overwintering site inside.
They enter through any gap they can navigate: cracks in caulking around windows and doors, gaps where siding meets trim, spaces around utility penetrations, weep holes in brick, and gaps at the roofline.
The ones you find inside your Genoa living space during winter and spring are individuals that navigated from the wall void through an interior gap — typically around outlets, light switches, door casings, and ceiling fixtures.
They are not dangerous. They don't bite, sting, or reproduce indoors. But they are deeply annoying, and in large numbers they are a genuine quality-of-life issue.
This is the single most important thing to understand about stink bug extermination in Genoa : the treatment window that actually works is late summer, before peak aggregation begins.
Exterior perimeter treatment applied in August or early September, when stink bugs are beginning to move toward structures but before they've aggregated in large numbers, produces dramatically better results than treatment applied in October when aggregation is already underway.
Treatment applied after stink bugs are already inside the wall voids does not eliminate them — it creates a barrier that affects new individuals approaching the exterior but does not reach the population that's already overwintering inside the structure.
This is why homeowners who call Shahan Pest Control in September get substantially better outcomes than those who call in November.
The core of our service. We treat the full perimeter — foundation line, exterior walls, window frames, door frames, eaves, and roofline overhang — with residual insecticide applied before peak aggregation season.
Special attention to weep holes in brick construction.
We assess and seal high-probability entry points around windows, doors, utility penetrations, and roofline trim.
Targeted treatment of wall voids, attic perimeter, and pathways to reduce stink bugs entering living spaces.
Exterior treatment in spring to prevent re-aggregation and reduce surviving population.
Late summer is the best time • Limited peak season availability
For large-scale exterior aggregations on your Genoa home, professional treatment applied before the aggregation peaks is the right approach.
For Genoa homeowners, the optimal treatment window is late August to mid-September — before stink bugs begin aggregating on exterior walls in significant numbers. Waiting until October reduces treatment effectiveness substantially.
We can reduce the number that make it from the wall voids into your living space through targeted interior treatment. We cannot eliminate overwintering stink bugs already inside the wall structure. Spring emergence treatment combined with pre-season treatment the following fall is most effective.
Not structural damage. They don't chew wood, reproduce inside, or damage fabric or food. Their impact is entirely a quality-of-life issue.
Residual treatment typically provides effective protection through four to six weeks under normal fall weather conditions. Significant rainfall can reduce residual effectiveness.
Pricing is based on home size and the scope of the entry point work. Call us with your home's square footage and a description of your stink bug history — we can give you a straightforward estimate over the phone for most residential situations in Genoa .
Ask most homeowners in Genoa when they think about stink bug control, and the answer is usually some variation of "when I see them."
Brown marmorated stink bugs begin responding to shortening day length and cooling nighttime temperatures in late August. By the time large aggregations appear, many have already entered wall voids.
Professional exterior perimeter treatment creates a treated contact zone that affects stink bugs as they approach the structure.
The homes that don't have a stink bug problem in October are the ones where the decision was made in August.
