How long does a worker wasp live?

A worker wasp lives approximately 12 to 22 days. Workers are sterile females — they hatch from the pupa, take over foraging and nest-building duties from the queen, and die within a few weeks. This short lifespan is why a colony that seems small in June becomes a traffic jam at the nest entrance by August: those are not the same individual wasps, but a continuously replaced workforce produced by a queen who may lay hundreds of eggs over the season. The Scientific Reports study of Polistes dominula (PMC8012566) found workers and males 'typically live no longer than 30–40 days,' consistent with the 12–22-day figure from A-Z Animals for peak-summer workers.

How long does a queen wasp live?

A queen wasp lives approximately 10 to 12 months — far longer than any worker. She hatched as a reproductive female (gyne) in late summer, mated in fall, overwintered in a protected site such as a wall void, attic, or under loose bark, and emerged in spring to found a new colony entirely alone. She is the only individual from last year's colony to survive winter, and she will die when the new colony collapses in fall or shortly before, having spent the entire season laying eggs. The Scientific Reports study of Polistes dominula (PMC8012566) puts gynes at 'up to 1 year,' consistent with UNH Extension and Penn State Extension guidance.

Do wasps die in winter in New Hampshire?

Yes — virtually all of them. When the first hard frost hits, workers, males, and the founding queen all die within about a week. The sole survivors are newly mated queens that dispersed from the colony in late summer. These overwintering queens enter a cold-tolerant dormancy (diapause), sheltering in attics, wall voids, soffits, under bark, or in woodpiles. They are not active in winter, though a warm January or February day can rouse a queen into brief movement — which is why homeowners occasionally find a sluggish wasp indoors in the middle of winter. The vast majority of wasps in a given colony are dead by the time NH's first hard frost arrives, which in Manchester runs around October 19 to 29 per NOAA 1991–2020 normals. For detailed yellowjacket-specific overwintering, see /yellowjackets/do-yellow-jackets-die-in-winter.

When do wasps go away in New Hampshire?

Wasp colonies in NH collapse at the first hard frost of fall. But that date varies significantly by location. In Concord and Keene, the first hard frost typically arrives around early October (roughly October 1–3 per NOAA normals), meaning colonies there may already be dying back while Manchester residents are still seeing peak activity. Manchester–Boston Regional Airport's NOAA 1991–2020 normals put that first frost around October 19 at 50% probability and October 29 at 80%. So a Manchester homeowner asking in early October 'when will they go away?' has the honest answer: potentially three more weeks. Peak aggression is highest just before the colony collapses because colony size is at its maximum and natural food sources are declining.

Will the same wasp nest come back next year?

No. The old nest is never reused. Wasp nests are single-season structures built of chewed wood pulp. After the first frost kills the colony, the nest begins to deteriorate over winter. A new mated queen starting fresh in spring builds her own nest from scratch — she does not inhabit or expand the old one. That said, a new queen may choose the same sheltered spot your soffit, wall void, or porch railing offered last year, so the same location can host a new colony in successive seasons even though it is always a brand-new nest. UNH Extension and UMD Extension are explicit that NH wasp colonies are annual. Removing an old abandoned nest in fall is optional from a safety standpoint but can remove the site's appeal for next spring's foundresses.

When do wasps get most aggressive in NH?

August and September are the peak aggression window in New Hampshire. Colony size is at its maximum, foragers are at their most numerous, and the late-summer shift from protein foraging to sugar scavenging drives more wasp encounters near food and drinks. UNH Extension notes that 'once the first frosts come, the wasps may become especially aggressive' because food becomes scarcer at exactly the time the colony is largest. The combination of a peak-size colony, reduced natural food, and defensive behavior around the nest entrance makes late-summer the highest-risk period for stings in NH. Anchor recommends scheduling professional removal before peak activity rather than waiting it out.

What is the wasp life cycle from egg to adult?

The wasp life cycle has four stages: egg, larva, pupa, and adult. The queen lays a single egg in each hexagonal cell; it hatches in roughly 5 to 8 days. The larva goes through several instars, fed protein (insects) by adult workers, over the course of about two weeks. The larva then pupates inside a silk-capped cell, undergoing full metamorphosis. Full egg-to-adult development runs roughly 28 to 48 days, according to Manaaki Whenua / Landcare Research NZ. Early in the season the queen does all foraging herself and tends the first brood; once the first workers eclose they take over foraging and building, and the queen focuses on laying. Later in the season, the colony produces reproductive males and new queens (gynes) rather than sterile workers.

Do male wasps sting or die after stinging?

Male wasps cannot sting — they have no stinger. Males (drones) are produced late in the season for one purpose: mating with new queens. Once mating occurs in fall, males die. They do not overwinter. This matters for NH homeowners seeing a swarm of wasps around a nest in late September: some of those individuals may be males doing mating flights, and they are physically incapable of stinging you. Only female workers and the queen can sting. And unlike honey bees, wasps (male or female) do not die after stinging — their stinger is smooth and unbarbed, so females can sting repeatedly. For more on this, see our page on do-wasps-die-after-stinging.

Why do I see a wasp indoors in winter or early spring?

A single wasp appearing indoors in January, February, or March is almost always an overwintered queen that has been roused from dormancy by warmth — a heated attic, a south-facing wall, or an unusually mild day. She is not part of an active winter colony (there are no winter worker colonies in NH) — she is a lone foundress waiting for spring, temporarily confused by the indoor warmth. She poses minimal threat and will usually die on her own if left in a cool space or can be released outdoors when temperatures are above freezing. This is most common in homes with heated attics or south-facing wall voids where paper wasps or yellowjacket queens have sheltered for the winter.

Where do wasps go in winter — where do queens hide?

Mated queens — the only wasps to survive winter — seek sheltered, protected sites to spend the cold months in diapause. In NH homes and properties, typical overwintering sites include attics, soffits, wall voids, behind shutters and siding, under loose bark on firewood or standing trees, inside woodpiles, and within hollow logs. Queens may also hide in leaf litter and soil crevices in wooded areas. UNH Cooperative Extension specifically notes that northern paper wasp females 'overwinter individually in protected places such as inside building walls, in attics, or under loose bark.' Because queens tolerate cold via antifreeze proteins (documented by Akre et al. 1981, USDA Handbook 552), they can survive NH winters in these sites — but they become briefly active if the microclimate warms above roughly 50°F, which is when homeowners spot them.

How Long Do Wasps Live? Lifespan, Life Cycle & the NH Season

Biology

Wasp lifespan depends entirely on caste. Worker wasps — the ones you see all summer — live roughly 12–22 days. The queen lives approximately 10–12 months and is the only individual to survive winter. Males are short-lived and die after fall mating. In New Hampshire the colony is an annual: founded by one lone queen in late April or May, expanding through summer, peaking in August–September, then collapsing entirely at the first hard frost. Manchester-area colonies persist into late October — about two to three weeks later than inland Concord or Keene — because the airport's frost dates run late under NOAA 1991–2020 normals.

Overview

The wasps bothering your Manchester cookout live only weeks — their queen survives all winter

"When will these go away?" is the question behind almost every search for how long wasps live. The honest answer has two parts: it depends on the caste, and in New Hampshire, it depends on where you live.

The worker wasps — the ones you see darting at your soda and guarding the soffit — live only about 12 to 22 days. They emerge from the pupa, join the foraging force, and die within a few weeks. The queen, by contrast, is the engine of the whole operation. She emerged from last year's colony in late summer, mated, found a protected overwintering site, and spent the winter dormant in an attic, wall void, or under loose bark. She founded this year's nest alone in late April or May. She will live roughly 10 to 12 months in total — far longer than any worker — and she is the only individual to survive the winter. Males are produced late in the season and die after mating. They do not overwinter.

The colony itself is strictly annual. That nest you are watching was not there last year, and it will not be there next year. Only the queen survives — not that queen, but a new one she produced this summer. Old nests are never reused, though a new foundress may return to the same sheltered spot your wall void or soffit offered last season.

In terms of geography: Manchester and the southern tier of Anchor's service area (Rockingham, Hillsborough, Merrimack counties) run about two to three weeks later to first frost than inland Concord, which typically frosts in late September to early October, and Keene, which is similar. Manchester's airport normals put the first hard frost around October 19 at 50% probability or October 29 at 80% probability. That means a colony still active in early October in Manchester may have three more weeks of peak-size, peak-aggression behavior ahead of it — which matters for deciding whether to wait or to call.

New Hampshire context

Wasp season in southern and central New Hampshire — a frost-calibrated calendar

NH's wasp calendar is governed by spring warm-up and the first hard frost. Because Manchester's airport frost runs late compared with inland areas, southern-NH colonies persist two to three weeks longer than those around Concord, Keene, or the Lakes Region. The wasps most NH homeowners encounter are social species — northern paper wasp (Polistes fuscatus), European paper wasp (Polistes dominula), and yellowjackets (Vespula spp.) cross-referenced from the /yellowjackets/ hub. All share the same annual colony structure: one overwintered queen starts each colony; workers live weeks; the colony peaks in August–September; and the first hard frost ends it. Solitary wasps — mud daubers active all summer, great black wasp and cicada killer from July through August–September — operate on individual adult seasons rather than colony cycles, but their adults are also frost-limited. None of these solitary species overwinter as adults in NH. For Manchester, Nashua, Bedford, Derry, Salem, and the greater Rockingham–Hillsborough–Merrimack area, homeowners should expect social-wasp colonies to remain active and at peak size from mid-August through mid-to-late October, with the timing varying year to year around the NOAA median dates.

Biology

Wasp lifespan, life cycle, and the 12-month NH season

Every social wasp colony in New Hampshire — paper wasps, yellowjackets, bald-faced hornets, and the European hornet — follows the same annual arc: a single overwintered queen founds the colony alone in spring, workers take over through summer, the colony peaks in late summer, and the first hard frost kills all but the new mated queens who will start the cycle again next year. Understanding that arc answers the most common questions homeowners ask: how long wasps live, when they go away, and why they get crankier as summer ends.

~12–22 days

Worker lifespan

~10–12 months (overwinters as the sole survivor)

Queen lifespan

Short-lived; dies after fall mating; does not overwinter

Male lifespan

Only newly mated queens survive winter — the founding queen, all workers, and all males die at the first hard frost. The old nest is never reused; each spring begins with a lone overwintered queen building from scratch.

Egg

Hatches in ~5–8 days

The queen (early season) or a worker-tended queen (mid-season) deposits a single egg in each hexagonal cell of the paper comb. Eggs are tiny, white, and attached to the cell wall.

Larva

~2 weeks through several instars

Larvae are legless, grub-like, and entirely dependent on adults for protein — workers hunt caterpillars, flies, and other insects and chew them into a paste for the larvae. Larvae produce a sugary secretion that adult workers also consume, a form of nutritional exchange that reinforces foraging behavior.

Pupa

~1–2 weeks (capped cell)

The mature larva spins a silk cap over its cell and undergoes complete metamorphosis inside. Full egg-to-adult development takes roughly 28–48 days. Newly eclosed workers are pale and soft-bodied for a day before hardening.

Queen emergence (spring foundress)

Late April – early May in southern NH

An overwintered mated queen breaks diapause once overnight lows hold above roughly 50°F. She begins building a small starter nest — sometimes no larger than a ping-pong ball — entirely alone, laying eggs and foraging for protein simultaneously. No workers yet exist to help her.

Colony growth

June through early August

The first workers eclose and take over foraging, building, and larval care. The queen retires to full-time egg-laying. The colony expands steadily — nest cells are added in concentric rings — and foragers shift from all-protein to a mix of protein and sugar as larval demand changes.

Peak and reproduction

Mid-August through mid-September

The colony reaches maximum size. New queens (gynes) and males (drones) are produced instead of sterile workers. Foragers scavenge sugar aggressively — this is the NH cookout and apple-orchard conflict window. Aggression near the nest peaks as the colony is simultaneously at its most defensive and its most resource-stressed.

Collapse

First hard frost — Manchester ~Oct 19 (50%) / ~Oct 29 (80%); Concord ~Oct 3; Keene ~Oct 1

Within roughly one week of the first hard frost, workers, males, and the founding queen die. Only newly mated queens that dispersed from the colony in late summer survive, each seeking a sheltered overwintering site. The nest is abandoned — it will not be reused. A new mated queen may return to the same site next spring, but she will build a brand-new nest from scratch.

12-month NH phenology

NH's wasp calendar is governed by spring warm-up and the first hard frost. Because Manchester's airport frost runs late, southern-NH colonies persist 2–3 weeks longer than those around inland Concord and the Lakes Region. The table below applies primarily to social wasps (paper wasps, yellowjackets) — the species responsible for nearly all NH sting and nest-removal calls.

Jan

dormant

Only mated queens alive, overwintering in attics, wall voids, soffits, woodpiles, and under loose bark; no colony activity anywhere in NH

Feb

dormant

Continued diapause; a warm spell above ~50°F can briefly rouse a queen indoors — this is why a sluggish wasp may appear on a sunny winter day

Mar

dormant

Late-month warming begins; queens in heated attics or south-facing wall voids may stir; still no nest-building activity in southern NH

Apr

building

Queens emerge as lows consistently exceed ~50°F (typically late April in Manchester / Nashua / Bedford); solo foundresses begin constructing small starter nests under eaves, soffits, and in wall voids; colony is single-queen with no workers yet

May

building

Colony in construction; queen both forages and lays eggs alone; first worker brood in development inside cells; nest may reach golf-ball size by month-end; virtually invisible to homeowners

Jun

building

First worker brood ecloses; queen hands off foraging and building to workers; colony expands steadily; still relatively small and low-conflict; a small exposed nest can sometimes be knocked down safely at this stage

Jul

building

Colony expands rapidly; workers handle all foraging (mostly protein for larvae); nest visible on eaves, soffits, grills, playsets; aggression near the nest starts to rise; solitary wasps (cicada killer, great black wasp) also active

Aug

peak

Colony reaches maximum size; sugar foraging begins as larval protein demand drops; NH cookout and apple-orchard encounters peak; first sting reports climb; this is the prime removal window before aggression intensifies further

Sep

peak

Maximum size continues; new queens and males produced; aggression peaks — workers are defensive and food-stressed simultaneously; UNH Extension notes wasps 'may become especially aggressive' as frost approaches; scavenging at trash and recycling is highest

Oct

declining

First hard frost arrives: Concord ~Oct 3, Keene ~Oct 1, Manchester ~Oct 19 (50%) / Oct 29 (80%); workers, males, and founding queen die within ~1 week of hard frost; new mated queens disperse to overwinter; abandoned nests visible but empty

Nov

dormant

All workers dead across NH; abandoned nests remain on structures and begin decomposing; overwintering queens in deep diapause in protected sites

Dec

dormant

Deep diapause; mated queens cold-tolerant via antifreeze proteins; no wasp activity; nest is now a hollow paper shell — not a risk but not reused next year either

Peak Building Declining Low Dormant

NH overwintering

Only newly mated queens survive the NH winter, sheltering in dormancy from roughly October through late April. They may occasionally appear indoors on warm winter or early-spring days — a single sluggish wasp in January is almost always an overwintered foundress roused by indoor heat, not a sign of an active colony. UNH Cooperative Extension confirms that northern paper wasp mated females overwinter in 'protected places such as inside building walls, in attics, or under loose bark.'

Attics (heated or unheated; south-facing preferred)
Soffits
Wall voids (behind clapboard, vinyl siding, cedar shingles)
Behind shutters and decorative siding trim
Woodpiles and stacked lumber
Under loose bark on standing or fallen trees
Stone walls (gaps between granite blocks)
Hollow logs and stumps

NH activity calendar

Peak: mid-August through mid-September (colony maximum size and maximum aggression) Manchester first hard frost ~Oct 19 (50%) / Oct 29 (80%) per NOAA 1991–2020 normals; Concord ~Oct 3; Keene ~Oct 1
