Almost every wasp in a colony dies once real cold arrives. The workers, the males and the old queen do not survive the season, and the nest they built is abandoned for good. Only the new queens produced in late summer live through winter, tucked under loose bark, in fallen leaves, or inside a wall or attic where the temperature stays steady. Each surviving queen starts a brand-new nest somewhere else the following spring. Last year’s nest never fills back up.
The paper wasp nest under the edge of your porch roof has been busy since June, and sometime in late October you notice the traffic has stopped. Nobody is coming or going. Knowing where wasps go in the winter answers the two questions that follow: is the nest empty, and will they be back in the same spot next year.
The Colony Does Not Move. It Ends.
A yellow jacket or paper wasp colony runs on a one-year clock. It starts with a single queen in spring, builds through summer, peaks in late August and September, and then finishes.
In early fall the colony switches production. Instead of more workers, it raises new queens and males. Those leave the nest, mate, and the males die within weeks. The workers stop being fed as the queen’s egg-laying tails off, and they die as nighttime temperatures drop. The old queen dies with them. By the time the Upstate gets its first hard frost, usually somewhere between late October and mid-November depending on the year, the colony is finished.
Hornets follow the same schedule. A bald-faced hornet nest, the gray football shape that turns up in a tree or under a second-story roof overhang, empties out the same way and is dead by December. The one exception we see in the Upstate is a yellow jacket colony nesting inside a heated wall, which can keep going into early winter. That stays uncommon, and you will see it as steady traffic at one spot on the siding long after the outdoor nests have gone quiet. A colony like that is still active and still defends itself, so it is one to call us about rather than investigate up close.
Only the New Queens Make It Through
A mated queen finds a sheltered gap and shuts down for the season. She does not eat, does not fly, and does not need the nest.
Where she picks matters to homeowners, because the list includes places attached to your house.
- Under loose bark on a standing dead tree or a woodpile
- In fallen leaves and mulch beds along the base of the house
- Inside the hollow space in a wall, the attic, or the gap behind siding
- In a shed, detached garage, or an unheated crawl space
A single overwintering queen in your attic is not a colony and will not damage your house. She is one insect waiting out the season. She can still sting if she is handled, so leave her where she is.
Why a Wasp Shows Up Inside in January
Upstate winters run mild and uneven. A stretch of 65-degree days in January warms the inside of the walls and the attic enough to pull a sheltering queen partly out of her winter sleep. She moves toward light, which from inside a wall means the gap around a light fixture, a recessed ceiling light, or the seam at a window frame, and she ends up on your kitchen ceiling.
That wasp is groggy and slow, and she came from inside the house rather than from outdoors. Our page on wasps getting in the house walks through the openings that let this happen and how to close them.
Can You Take the Old Nest Down Now?
Usually, but only once you are certain it is finished. After a hard freeze, a paper wasp or yellow jacket nest from this season is empty, and it will stay empty. These wasps never reuse a nest. Next spring’s queen builds a new one somewhere else, and rarely on the same spot.
The exception is the wall nest described above. If you have watched wasps coming and going from a spot on the house this month, that colony is still alive, and it is ours to handle rather than yours.
Removing it in winter is worth doing for two practical reasons. An abandoned nest left in place attracts carpet beetles and other insects that feed on the leftover material inside it. And a nest under a roof overhang in February is a hard thing to identify at a glance in May, when you are trying to work out whether a new one has started.
If the nest is one you can reach standing flat on the ground, wait for a genuinely cold morning rather than a mild one, because a warm afternoon in December can wake a lingering wasp up long enough to sting. Scrape it off, bag it, and put it straight into the outdoor trash rather than a bin in the garage.
Everything else is a job for us. If the nest sits inside a wall, up in the roof overhang, anywhere that would put you on a ladder, or anywhere you are not certain the colony has finished, leave it alone and call. And if anyone in your household reacts badly to stings, do not go near a nest at all, whatever the month. Our wasp nest removal service covers those spots.
What This Means for Next Spring
Every queen that survives the winter near your house is a potential nest in April. Reducing the sheltered spots she can use is the most useful winter work you can do.
- Clear fallen leaves and heavy mulch back from the base of the house
- Move the firewood stack away from the exterior wall
- Screen the vents in the peak of the roof and close gaps behind loose siding
- Seal around exterior light fixtures, outdoor faucets and where cables enter the wall
Early spring is also when a single treatment does the most, because you are dealing with one queen starting out rather than a full colony. An April paper wasp nest is about the size of a bottle cap with a single wasp on it. By August that same nest holds dozens of workers, and a yellow jacket colony in the ground or a wall can run to thousands. Either one is a job to hand off rather than take on. Our South Carolina wasp guide covers which kinds nest where, and the wasps, yellow jackets and hornets page in our pest library explains how we treat each one.
Let Us Handle the Nest You Cannot Reach
Late fall and winter are the quiet stretch for this work, and it closes as soon as spring queens start building again in March. If there is an old nest tucked up under a roof overhang or inside a wall on your property, we will take it out and seal the opening behind it so next year’s queen has to look elsewhere. Wasps, yellow jackets and hornets are covered at no extra charge on our pest plans. We have been serving Upstate families since 1974, and if the bugs come back, we will too. Call (864) 399-9262 to get on the schedule.
