Protecting Portland Homes & Businesses From Invasive Stink Bugs
When brown marmorated stink bugs invaded Portland, they changed pest control forever. As the West Coast's entry point for this invasive species, Portland now faces some of the nation's longest invasion seasons, from August through November. Our area supports two full generations each year, meaning double the pest problems.
Croach® Pest Control has protected Portland homes since 2009, becoming the region's stink bug specialists. With over 15 years of experience and thousands of five-star reviews from Beaverton to Gresham, we've perfected the timing and techniques that actually work in our unique climate.
How Portland Experiences Stink Bug Problems
In August and September, it's common to see hundreds of stink bugs gathering on south-facing exterior walls before the rains return. You could also find flusters in your attic or on upper floors, or even inside the home as rain drives them in. They can also wreak havoc on our gardens, damaging tomatoes, berries, and vegetables in our urban farms and community plots.
Portland's weather destroys consumer products faster than anywhere else. Hardware store sprays wash away with the first autumn rain, while our professional applications bond to surfaces and resist moisture for 90 days.
Oregon State University Extension confirms that DIY soap traps might catch a few bugs, but miss the thousands hiding in wall voids. Those YouTube remedies using essential oils? They'll need reapplication every three days during Portland's rainy season—costing more than professional treatment.
That distinctive cilantro smell means aggregation pheromones have already marked your home. Most Portlanders react when they see September swarms, but early intervention in August can prevent the chemical trail that draws thousands more.
Timeline of Portland's Extended Stink Bug Season
August
Portland homeowners should treat in late August, at least before Labor Day. This narrow window (after summer heat but before fall aggregation) offers 5x better prevention than panic treatments in October.
September-October
When temperatures hit 65-75°F, stink bugs blanket Portland homes. Did you miss the August prevention window? October treatments still help but require heavier applications.
March-May
Portland's infamous spring weather creates chaos. One 70-degree day in March sends overwintered bugs into frenzy mode. Spring emergences often overwhelm homeowners unprepared for the "second invasion."
Year-Round Urban Pressure
Unlike rural areas, Portland's heat island effect and diverse ornamental plants mean stink bugs stay active longer. Consider pest treatments throughout the year, especially in years we have a mild winter.

Our Stink Bug Treatment Process In Portland
Developed Through 15 Years of Local Experience
Step 1: Portland Property Analysis
We inspect based on Portland patterns—checking south walls that get afternoon sun, examining areas where siding meets brick (common in older Portland homes), and identifying entry points around those vintage single-pane windows.
Step 2: Weather-Resistant Barriers
Portland's 36 inches of annual rain demands special formulations. We apply moisture-resistant treatments that maintain 80% effectiveness despite our wet climate— something store-bought products can't achieve.
Step 3: Vintage Home Exclusion
Portland's charming 1920s bungalows and Craftsman homes need specialized sealing. We address unique challenges like original wood siding gaps, historic window frames, and settled foundations common from Irvington to Sellwood.
Step 4: Seasonal Monitoring
Your technician tracks Portland's microclimate patterns, adjusting service timing based on whether you're in rainy Northwest Portland or slightly drier Happy Valley.
Treatment typically shows results within 48 hours, with maximum control achieved before the next rain cycle.

Learn All About Ant Control In Portland
The more you know about ants, the better you can keep them out of your home. Here are some common questions our customers in Portland ask about our ant control services:
The most common household ants in the Pacific Northwest are odorous house ants and pavement ants. Portland homes may also deal with carpenter ants and moisture ants, especially in damp or wood-damaged areas.
Ants may enter through cracks around foundations, windows, doors, utility openings, pipes, vents, siding gaps, crawl spaces, and areas where vegetation touches the home.
Yes. Ants may nest in wall voids, under homes, around insulation, near plumbing, or in damp wood. This is one reason a professional inspection is helpful.
