If you’ve started seeing brown, shield-shaped bugs crawling around your windows and siding in late September, you’ve got stink bugs. The brown marmorated stink bug arrived in Iowa within the last couple of decades and has established itself as one of the most aggravating fall invaders in the region. They don’t bite, they don’t sting, and they won’t destroy your home — but they will show up in significant numbers, and if you make the mistake of crushing one, you’ll know immediately how they got their name. In Van Meter, IA, Miller Pest Solutions provides exterior barrier treatments that stop stink bugs before they move inside for winter.

Signs of a Stink Bug Problem

  • Aggregations on exterior walls — Large numbers clustering on south- and west-facing siding, window frames, and fascia boards as temperatures drop in fall.
  • Bugs inside near windows — Finding live or dead stink bugs on windowsills, around light fixtures, or emerging from wall voids on warm winter days.
  • Foul odor — The unmistakable musty, cilantro-like smell released when a stink bug is disturbed, crushed, or trapped.
  • Spring emergence — Large numbers suddenly appearing inside the home as temperatures warm and overwintering bugs try to exit.
  • Gaps around window frames and soffits — Stink bugs exploit even small openings. Finding entry points is key to long-term control.

Why Stink Bugs Are Common in Van Meter

Brown marmorated stink bugs (Halyomorpha halys) are an invasive species originally from Asia that have spread throughout much of North America. Iowa’s mix of agricultural land, orchards, and residential landscaping gives them plenty to feed on through summer — soybeans, corn, fruits, vegetables, and ornamentals are all on the menu.

As nights get cold in late September and October, stink bugs switch into survival mode. They instinctively seek warm, sheltered spaces to spend the winter, and they’re very good at finding them. Older homes in Van Meter with less-than-perfect weatherstripping and aging siding give them plenty of entry points. Once inside walls, they can aggregate in large numbers and survive until spring. A warm day in February might bring dozens emerging from wall voids into your living space.

Unlike many pest problems that get worse without intervention, stink bugs are largely preventable if you treat at the right time.

Our Stink Bug Control Process

Timing is everything with stink bug control. The window for effective exterior treatment is early fall — ideally before mid-October — while stink bugs are still aggregating on the outside of buildings and haven’t yet pushed inside. Miller Pest Solutions applies perimeter barrier treatments to exterior surfaces, paying close attention to south- and west-facing walls, window frames, door frames, rooflines, and soffit areas where stink bugs concentrate.

We also identify and address structural entry points — gaps around utility penetrations, deteriorating caulking, missing or damaged weatherstripping, and openings around attic vents. Physical exclusion combined with a well-timed barrier treatment is far more effective than trying to deal with stink bugs after they’ve overwintered in your walls.

If you’re dealing with spring emergence — bugs coming out of walls as weather warms — we can treat accessible void areas and harborage zones. This situation is trickier, but manageable with the right approach.
