Because everyone knows exactly what happens if you make the mistake of squashing it, there’s a particular kind of dread that comes with spotting a stink bug clinging to your curtain or crawling along a windowsill, mostly. As temperatures start dropping through fall, these mottled brown pests go into full house-hunting mode, searching for somewhere warm to ride out the winter, and your home looks exactly like what they’re after. The good news is keeping them out doesn’t require anything drastic, just a bit of sealing, some strategic scents, and a few small habits around the house. Here’s how to stop them before they ever get inside.
This isn’t random timing. As the weather cools, stink bugs actively seek out warm, sheltered spots to spend the winter, and they’re not fussy about how they get in. They’re genuinely opportunistic, slipping through whatever gap happens to be available rather than targeting your home specifically.
Homes that catch a lot of direct sunlight tend to see more activity too, since the warmth draws them in even before the weather turns properly cold.
If you do spot one indoors, resist the obvious instinct. Stink bugs release a genuinely unpleasant odour when crushed, which is exactly how they get their name. Vacuum them up instead, or gently guide them into a cup and release them outside. It’s a small habit, but it’s the difference between a quick, odourless cleanup and a smell that lingers in the room for hours. None of this guarantees a completely stink-bug-free home through autumn, but between sealing entry points, cutting back what attracts them, and knowing how to handle the odd one that gets in anyway, you’ll see a genuine difference by the time the weather properly turns cold.
