You might think, "Alright, I’ll just wait for the first frost!" And sure, a hard frost will kill any stragglers. But the UK doesn’t always get that big freeze before November. Some wasps will cling to life in a warm attic or inside your porch if they find a cozy spot.
Here’s the irony: the queens that survive are the ones you’ll hate next spring. They’re the reason that empty spot in your garden fence suddenly has a grey, papery nest in June. So when you see that last wasp crawling feebly on your kitchen window, try not to feel too bad—it’s probably a queen, and she’s just looking for a winter bunker.
Most people think wasps die in October. Realistically, the bulk of them die between mid-September and late October, depending on how mild your local weather is. Down in Cornwall, they might last into November. Up in Scotland, they’re gone by the end of September.
What About the Nests? Do They Die, Too?
Here’s a common question: "If the queen dies, does the nest die?" Yes, but not in the way you imagine. When the old queen stops producing, no new workers are born. The existing workers live out their short lives (a few weeks at most), and then the nest becomes a ghost town.

Wasps never reuse a nest from the previous year. That big, papery ball you find in your loft is just a relic. A new queen won’t move into it; she’ll start her own brand-new colony from scratch. Nature is weird like that—no hand-me-downs.
So if you find a nest in October, it’s almost certainly dead or abandoned. You can leave it, but if you’re worried, wait until a few frosts have passed. Then you can knock it down without risking a stinging—just wear gloves, because those dead ones can still look scary.
