If you have spotted wasps in your loft, found a wasp nest in your roof, or noticed a stream of wasps flying in and out of a gap in your eaves in Stevenage, you need a qualified local wasp exterminator — not a national call centre. Not sure what you're looking at? Check our guide to the tell-tale signs of a wasp nest before you call.
Stevenage is a town of two halves and that distinction shapes every wasp nest call-out we attend here. The Old Town High Street and surrounding streets — pre-dating the New Town designation — have genuine period housing including Victorian terraces and older properties producing classic loft and chimney nests. The post-war Mark I New Town estates of Bedwell, Pin Green, Shephall and Chells were built rapidly from 1949 onwards, with construction characteristics — Easiform concrete, flat-to-pitched roof junctions, original air bricks — that produce a very different nest access profile.
We cover every street in SG1, SG2. If you are searching for a wasp exterminator near you in Stevenage, you have found us. Tempted to handle it yourself? Read why we strongly advise against it in our DIY wasp nest removal guide, and see what happens if you leave a wasp nest untreated.
01 — Our Services
We specialise exclusively in wasps and hornets. It is all we do — which means we are better at it than any general pest controller juggling rats, fleas and cockroaches alongside the odd wasp job.
Same-day domestic wasp nest treatment across all SG1, SG2 postcodes. Professional-grade insecticide powder (PA1/PA6 restricted) applied at the entry point — colony typically inactive within 2-3 hours.
European hornet nests treated using the same method at the same fixed price. Can't tell wasps from hornets? We identify species over the phone in under five minutes.
Call 01727 789571. From our St Albans base we reach Stevenage in approximately 35-50 minutes.
Restaurants, offices, schools, care homes, landlords and facilities managers. We prioritise commercial call-outs and operate discreetly.
We identify species before sending anyone out. For honey bee swarms we refer to local BBKA-registered beekeepers who often relocate at no charge.
Deep roof voids, underground nests, cavity walls and listed buildings — without invasive work.
02 — Local Knowledge
Britain's first designated New Town surrounds a much older market town centre, and our work here flips between Victorian roofline treatments and 1950s estate cavity-wall work, often on the same day.
Stevenage Old Town High Street and the streets immediately around it have Victorian and Edwardian terraces, period commercial-to-residential conversions, and older village-style properties. These produce classic loft nests through roofline gaps and chimney nests in original stacks. The Old Town remains our highest-volume call-out area within SG1.
The original 1950s Easiform construction of the early New Town estates creates specific nest access scenarios — flat-roof-to-cavity-wall junctions, original air brick vents, and gaps around utility penetrations are the most common entry points. We treat regular call-outs throughout SG1.
SG2 covers the eastern and southern New Town estates with construction spanning the 1960s and 70s. Gardens in SG2 tend to be larger, and proximity to Shephall Green and the rural fringe toward Aston and Watton-at-Stone creates conditions for ground-nesting wasps alongside the standard building nests.
The northern New Town estates of Fishers Green and Martins Wood sit adjacent to Fairlands Valley Park — Stevenage's principal green space. Properties immediately bordering the park have noticeably higher garden nest frequency, driven by the park's woodland and rough-grassland margins acting as queen-wasp habitat.
03 — Where We Find Them
The type and location of a wasp nest varies considerably by property age, construction and area. Here is what we most commonly encounter in Stevenage:
| Nest location | What we find in Stevenage — and where |
|---|---|
| Loft / roof void | Common across all Stevenage postcodes. Old Town Victorian properties produce the most frequent loft nests. |
| Soffits and flat-roof junctions | Defining feature of Mark I New Town construction in Bedwell, Pin Green and Symonds Green. |
| Wall cavities and air bricks | Original Easiform construction across the SG1 estates and 1960s-70s SG2 stock. |
| Chimneys | Old Town period stacks; some original Aston, Walkern and Knebworth village cottages. |
| Underground in gardens | Above average in streets adjacent to Fairlands Valley Park and on the SG2 rural fringe. |
| Garden sheds, garages and outbuildings | All areas. Larger SG2 plots particularly prone. |
Below is every nest scenario we encounter in Stevenage, with the specific local context. If your situation isn't listed it almost certainly fits one of these — or call us and describe it.
1950s Easiform construction has very specific entry points — flat-roof junctions, air brick vents and utility penetrations. Treatment is applied at the entry point externally.
Streets bordering the park see above-average garden nest frequency every season. Treated at the entry hole at dusk.
Classic period-property scenarios. Loft nests are treated at the roofline gap; chimney nests are treated through the stack — never light a fire to smoke them out.
Our most common Stevenage call-out. Treated entirely from the outside via the entry point at roofline level — no loft access required and nothing needs to be cleared from the loft beforehand.
Wasps enter through gaps between or beneath tiles and nest inside the roof void. Powder is applied at the tile-gap entry point from outside — no tiles need to be lifted.
Boxed-in soffits can hide a substantial colony behind a narrow gap. We identify whether the nest is in the soffit void itself or the main roof void from the flight pattern before treatment.
Treated via the chimney entrance. Never light a fire to "smoke them out" — wasp nests are made of dry paper and are highly flammable.
Wasps enter through a loose mortar joint, an open air brick, or a gap around a pipe. Harder to locate but straightforward to treat once the entry point is identified.
A hole in the lawn with low-level wasp traffic is the classic sign. Never block the entrance or pour anything into it; we treat the entry hole with insecticide powder at dusk.
Treatment is applied at the edge of the decking — boards never need lifting. The colony is rendered inactive within a few hours.
Often discovered when the shed door is opened for the first time in summer. Nests typically establish in the roof void or behind cladding.
More common than people expect — and often only spotted from the flight path when gardening nearby. Treated at the visible entry-and-exit point.
Live wasps inside through ceiling light fittings, around the loft hatch or pipework gaps means an established colony is in the roof void directly above. Urgent — do not spray indoors, the nest must be treated at source.
04 — Pricing
No call-out charge. No survey fee. No hidden extras for difficult access, conservation area restrictions or larger-than-expected nests. The price you hear on the phone is the price you pay.
05 — How It Works
A few quick questions to confirm wasps, hornets or bees and to locate the nest. We give you a fixed price and book the earliest convenient slot — usually same day in Stevenage.
A PA1/PA6 licensed technician identifies the entry point from the wasp flight pattern — no need to access the loft.
Professional-grade insecticide powder applied at the entry point. Carried out externally in almost all cases.
Workers carry insecticide back into the nest, distributing it through the entire colony including the queen. Typically inactive within 2-3 hours.
We explain residual activity to expect and leave you with a direct number in case of any concerns.
97% of Stevenage nests are resolved in a single visit. If yours requires a return, it is always free — no paperwork, no fuss.

08 — When to Act
| Period | What is happening in Stevenage |
|---|---|
| Mar — May | Queens emerge and prospect for nest sites. Most early-season sightings are bumblebees, masonry bees or mortar bees — harmless. Genuine wasp colonies are rarely established before late May. |
| June | First genuine call-outs. Colonies are small and easy to treat — same fixed price, faster job, less disruption. Best time to act. |
| July — August | Peak season. Nests can contain thousands of workers. Same-day availability is excellent if you call in the morning. Do not delay. |
| September | Colonies begin to break down. Workers become noticeably more aggressive — September is the most common month for unprovoked stings. |
| Oct — Nov | Colony dies off naturally. Nest abandoned. Seal the entry point after the season ends to reduce risk for next spring. |
For the complete month-by-month guide, see our Wasp Life Cycle page.

08c — Wasps or Bees?
A significant share of our early-season calls from Stevenage turn out to be bees, not wasps. This is very common in March, April and May when bumblebees, masonry bees and mortar bees are most active. Our wasp, hornet & bee species guide has side-by-side photos to help you check before you ring.
If we identify honey bees we will not treat them and will refer you to a BBKA-registered local beekeeper who may collect a swarm at no charge. Bumblebee colonies are small, short-lived and harmless; masonry and mortar bees nest individually in soft mortar and cause no structural damage in the short term.
