Brown marmorated stink bugs weren’t in Missouri a few decades ago. They’re an invasive species — arrived from Asia, spread rapidly across the U.S., and now they’re a reliable fall pest problem across Kearney and the rest of the Kansas City area. Come September and October, they start showing up on exterior walls, window screens, and eventually inside homes in large numbers.

The smell when you crush one is memorable. That’s not an accident — it’s a chemical defense mechanism. And once they’re inside your walls for the winter, you’ll be finding them until spring.

Signs of a Stink Bug Infestation

  • Large numbers on south- and west-facing exterior walls in September and October — they’re drawn to warmth and sunlight
  • Bugs congregating around window frames, door frames, and utility penetrations — looking for a way in
  • Bugs emerging indoors in late winter or early spring — often sluggishly crawling out of wall voids, attics, or around window trim
  • Musty or pungent odor indoors — especially if bugs have been disturbed or crushed
  • Visible aggregations in attic insulation — stink bugs overwinter in large clusters when conditions are right

Why Stink Bugs Are Common in Kearney

Brown marmorated stink bugs are now well-established throughout Missouri, including Kearney. The Kansas City metro’s mix of mature residential neighborhoods, agricultural edges, and wooded corridors gives them plenty of summer habitat — they feed on fruit, vegetables, ornamentals, and garden plants. As summer winds down and temperatures start dropping, they shift into survival mode.

Homes in Kearney with older construction, wood siding, or significant landscaping against the foundation tend to see the heaviest pressure. South- and west-facing walls collect the most afternoon heat, which is exactly where stink bugs congregate before finding entry points.

Once inside, they don’t breed — they just wait out the cold. The problem is that “waiting it out” means months of them slowly emerging into living spaces.

Our Stink Bug Control Process

The most effective stink bug control is prevention — treating before they enter, not after they’ve already settled in for winter.

  • Exterior perimeter spray in early fall — applied to siding, windows, soffits, and foundation before stink bugs begin aggregating; contact kill plus residual barrier
  • Crack-and-crevice sealing — caulking gaps around window frames, door frames, utility lines, and pipe penetrations to physically block entry
  • Attic and interior treatments — for existing infestations, we treat wall voids and attic spaces where they’re overwintering
  • Vacuuming recommendations — if you find them indoors, we’ll tell you the right way to collect them without triggering the chemical defense (don’t crush them)

Timing matters. A fall treatment applied in late September or early October in Kearney will be far more effective than waiting until bugs are already inside.
