Here’s the cold, hard truth: most wasps in the UK don't even survive past September. The entire colony dies off when the weather turns cold and food runs dry. It’s a brutal, short life—they spend months building a nest, only to freeze or starve once autumn hits.
The real kicker? Only the new queens make it through. They’re the ones that mated in late summer, got fat on sugar, and now hunker down in a shed or under some bark to wait out winter. The rest—the workers, the old queen, the grumpy males—are just collateral damage.
So if you’re waiting for a specific "wasp deadline" on the calendar, you’ll be disappointed. It’s less about a date and more about a weather event. A warm October can keep them kicking—and annoying—for weeks longer than usual.
The "Drunk Wasp" Phase (a.k.a. Late September to October)
This is where it gets really fun. As the queen stops laying eggs and the colony collapses, the workers have no purpose. No larvae to feed, no nest to build. They just panic. And they get a serious sugar craving.
You know that wasp that lands on your fizzy drink and won’t budge even if you flick it? That’s a hungry, desperate wasp running on fumes. They’re not aggressive in the "protect the nest" way anymore; they’re just lazy and drunk. Honestly, they’re more annoying than scary at this point.

If we get a sunny spell in October—what gardeners call an "Indian summer"—you’ll still see them on the ivy or near fallen fruit. But cooler nights (under 10°C) will slow them down until they can’t move at all. That’s usually your signal that the season is done.
