If you’ve noticed a few shield-shaped bugs crawling along your walls or hanging out near your windows lately, you’re not alone. Every fall, as the air cools and the days get shorter, stink bugs start sneaking indoors in search of warmth. The good news? It’s completely normal. The bad news? They’re persistent houseguests who plan to stay until winter really sets in.
Why you’re seeing more of them right now
If you’re experiencing more stink bugs than usual, it’s not just you. Warmer falls and mild winters are one reason these pests are thriving longer.
Stink bugs are most active from September through October, but become extra noticeable as temperatures drop. That’s because they’re looking for warmth and shelter, not a new territory to conquer.
In short: they’re not multiplying in your house (thankfully). They’re simply seeking a cozy spot to overwinter—your walls, attic, or behind the curtains happen to be perfect for that.
Don’t panic (and don’t squish them)
Here’s the thing: stink bugs are harmless. They don’t bite, sting, or cause structural damage. But crush one, and you’ll quickly understand where the name comes from. The smell—thanks to a chemical defense mechanism—is not pleasant.
Instead of squishing, consider vacuuming them up or gently catching and releasing them outside.
Keep them out before they move in.
The best defense against stink bugs is a good seal. Check for cracks around doors, windows, and vents, and seal them with caulk or weatherstripping. Add screens to chimneys or attic vents, and turn off outdoor lights when possible. Stink bugs are drawn to the glow like moths to a flame.
Natural deterrents can help, too. Peppermint or
A sign of the season
Yes, stink bugs are annoying, but they’re also a weirdly reliable marker of fall. So before you panic that this year’s invasion is something new, remember: it’s not just you. It’s simply stink bug season—smelly, stubborn, and right on schedule.
