Why Stink Bugs Gather on Homes in Late Summer and Fall

Ahh, autumn—the pumpkin-eating, chill-in-the-air, movie-watching season that we all know and love. Unfortunately, we’re not the only ones, which is why stink bugs can seem especially problematic this time of year. In Omaha, you may notice those brown marmorated stink bugs and other seasonal invaders gathering on warm, sunny exterior surfaces as the temperatures change.
These bugs are primarily indoor invaders, and from late summer into early fall, they’ll begin to move inside through cracks and similar entry points in preparation for winter. That’s why we need to take action before they have a chance to get inside your home and become an even bigger problem.
Luckily, Mosquito Squad Plus of Omaha Metro can help. We offer stink bug control in Omaha, NE, and can even provide your first treatment within 48 hours, or it’s free.
Sunny Exterior Surfaces Can Become Staging Areas Before Winter
As the weather shifts in late summer during the transition to fall, stink bugs will gravitate towards sunny, south- and west-facing walls. Gaps around window and door frames, siding, soffits, and utility penetrations can become entry points, while attics provide sheltered space once the bugs are inside.
When those sunny exterior surfaces become staging areas for these pests, exclusion methods and stink bug control treatments matter most. If we can address the problem at the source and seal available entry points, we can help prevent these bugs from getting inside and making a mess come winter.
How to Reduce the Gaps Stink Bugs Use to Get Inside
You never want to share your home with stink bugs, but they can sure be stubborn to remove. That’s why preventing them from getting inside in the first place is key.
While professional treatments (that include exclusion methods) are the best way to reduce pests, you can help support our efforts by reducing the entry points around your home that they’ll use to get inside in the first place.
Here are a few tasks to get you started:
- Repair screens and weatherstripping
- Seal appropriate exterior gaps before mass entry
- Vacuum isolated indoor bugs rather than crushing them
- Avoid indiscriminate indoor pesticide use
- Maintain required ventilation and drainage when sealing.
When Seasonal Stink Bug Aggregation Needs Professional Help
Professional exterior inspections and treatments are most useful before stink bugs have a chance to get deep inside your walls and attic voids. That’s why our stink bug control in Omaha, NE can start as soon as you begin noticing those pesky brown bugs gathering on your sunny exterior walls.
After your initial inspection, once we’ve sealed all the identified entry points, we’ll use our EPA-registered products to create a treatment barrier around your home that helps prevent bugs from getting in. If you’re not satisfied, you can reach out within 14 days of your treatment, and we’ll come back to reapply it at no extra cost. It’s that simple!
