Brown marmorated stink bugs weren’t a problem in Iowa twenty years ago. They arrived from Asia, spread rapidly across the country, and now show up in Milo homes every fall without fail. Their timing is predictable: as September temperatures drop, they start looking for a warm place to spend the winter — and your home is exactly what they have in mind. Miller Pest Solutions has been stopping fall invaders like stink bugs in central Iowa since 2001.

Signs of a Stink Bug Infestation

Stink bugs aren’t subtle once they’re active, but you might not realize how many are already inside your walls:

  • Adults appearing indoors in fall — The first sign is usually finding them on windows, walls, or ceilings as they move toward light.
  • Large numbers on exterior walls — Before they enter, stink bugs aggregate on the sunny south- and west-facing sides of buildings in September and October.
  • Bugs emerging inside in spring — Stink bugs that overwintered in wall voids become active again as temperatures warm and try to find their way out.
  • Distinctive shield shape — Brown marmorated stink bugs are about ¾ inch long with a mottled brown shield-shaped body and banded antennae.
  • Foul odor when disturbed — The smell is skunky, cilantro-like, or just plain awful. This is their defense mechanism. Don’t crush them indoors.

Why Stink Bugs Are Common in Milo

The brown marmorated stink bug (Halyomorpha halys) is now well-established throughout Iowa, including Milo. It’s an invasive species without the natural predators that keep it in check in its native range. During summer, stink bugs feed on crops and garden plants — corn, soybeans, fruit trees, tomatoes. Come fall, every adult that survived the season is looking for a warm overwintering site.

Homes and buildings near fields, orchards, or wooded areas in Milo tend to see heavier infestations. The bugs can travel miles to find suitable winter shelter, and once a property has been used as an overwintering site, the aggregation pheromones they leave behind attract future populations. Early treatment breaks that cycle.

Our Stink Bug Control Process

The most effective stink bug control is proactive exterior treatment in early fall, before they enter. Treating after they’re already inside walls is far more difficult. Our process includes:

  • Exterior perimeter treatment — Applied to the building envelope, eaves, soffits, window and door frames, and foundation in late September/early October before major aggregation begins.
  • Entry point identification — We look for gaps around utility penetrations, loose siding, damaged screens, unweathered windows and doors that are typical entry routes.
  • Exclusion sealing — Caulking, weatherstripping, and mesh screening recommendations to physically block stink bug access.
  • Interior treatment if needed — For homes already experiencing interior activity, we treat wall voids and other harborage areas appropriately.
  • What NOT to do — We advise customers never to crush stink bugs indoors. Vacuum them up with a bag you can seal and discard instead.
