Stink bugs weren’t even on Iowa’s pest radar until the 2010s. The Brown Marmorated Stink Bug arrived from Asia and spread fast, and now homeowners in Gilbert deal with them every fall without fail. They show up on screens, sneak through window gaps, and cluster inside walls and attics all winter long. Miller Pest Solutions helps Gilbert residents get ahead of stink bug season before the invasion starts.

Signs of a Stink Bug Infestation

  • Adults on exterior walls in fall — seeing stink bugs congregating on the south or west sides of your home in September or October is a warning that they’re about to try to get inside.
  • Bugs on window screens and around door frames — stink bugs probe every possible gap. Finding them clustered at entry points means they’re already looking for a way in.
  • Musty odor indoors — even without crushing one, large aggregations inside walls or attics produce a faint smell. Stronger odors happen when they’re disturbed.
  • Bugs emerging inside in winter or spring — on warm winter days they become active and wander out of wall voids into living spaces, looking confused and slow.
  • Garden and fruit damage in summer — stink bugs pierce and feed on tomatoes, peppers, apples, and corn, leaving dimpled or discolored spots on produce.

Why Stink Bugs Are Common in Gilbert

Iowa’s climate is perfectly suited to stink bug survival. Cool falls trigger their overwintering behavior right on schedule, and Gilbert’s mix of residential properties, gardens, and proximity to agricultural fields gives them abundant summer food sources before they seek shelter.

Older homes with wood siding, gaps around window frames, and unscreened attic vents are especially attractive. But even newer homes in Gilbert aren’t immune — stink bugs are persistent and will exploit any gap they can find. Once inside a wall void, they release aggregation pheromones that attract even more stink bugs, which is why an early-fall preventive treatment is so much more effective than trying to deal with them after they’re inside.

Our Stink Bug Control Process

The most effective stink bug strategy is a timed exterior perimeter treatment in early fall — before they enter. Miller Pest Solutions applies a residual insecticide to the exterior of your home, focusing on the south and west faces, eaves, windows, door frames, and foundation. The goal is to kill or deter bugs before they make it through the building envelope.

We also recommend sealing gaps around windows, doors, utility penetrations, and attic vents as a long-term exclusion measure. Caulk and weatherstripping go a long way toward keeping them out permanently.

If stink bugs are already inside walls or attics, we can treat those areas as well. One important note: do not crush stink bugs indoors. The odor glands release their smell when the bug is killed that way. Vacuum them up and dispose of the bag outside immediately — that’s the best DIY approach for bugs already in the living space.
