Here's what to watch for and how to deal with a nest safely. ![Large active wasp nest in the eaves of a Surbiton home, late summer afternoon](/images/misc/candid-photo-of-large-active-wasp-nest-in-eaves-of.webp) Wasp callouts across Surbiton and the surrounding areas typically peak between mid-July and mid-September, and this year is running true to type. In the last two weeks we’ve treated nests in Tolworth (loft void), Berrylands (shed roof), Long Ditton (cavity wall behind a hanging basket) and central Surbiton (a large aerial nest in a beech hedge). If you’re seeing more wasps than usual round the back door, up against the kitchen window, or working the bin on a warm evening, here’s what’s happening and what to do about it. ## Why late summer is the worst time Wasp colonies are small in early summer, a few dozen workers, still building the nest and mostly focused on hunting protein for the developing brood. That’s the point at which most nests get treated easily and cheaply. By late July they’ve grown massively. A typical common wasp nest can hold several thousand workers by August, and by early September the colony’s rearing new queens and drones and starting to break down. Workers switch from hunting protein to seeking sugar (which is why they’re all over your bin and your lager) and become significantly more aggressive as the nest declines. ![Wasps entering and leaving a cavity wall in a Surbiton house](/images/misc/wasps-swarming-near-small-entry-point-in-cavity-wa.webp) That combination, big colony, aggressive workers, sting-motivated behaviour, is why late-summer wasp incidents are much more common than early-summer ones. ## What to look for An active nest gives itself away with a steady traffic of wasps going to and from a single point. Common nest locations in Surbiton homes: - **Roof eaves and soffit boxes** with a small gap into the loft void. - **Cavity walls** with a tiny entry near a vent, cable hole or old air brick. - **Garden sheds and outbuildings**, especially older wooden ones. - **Hanging baskets and pergolas**, where a small paper nest can hide in plain sight. - **Hedges, bushes and bank holes**, particularly at the back of the garden. If you can see wasps consistently going in and out of the same small spot every couple of minutes, that’s an active nest. ## What NOT to do We say this every year and it still happens: **please don’t try to treat the nest yourself.** The single worst move is a can of shop-bought spray directed straight at the nest entrance. It kills a handful of workers, and the rest of the colony pours out looking for whatever caused the disturbance. If you’re on a ladder when that happens, you’re in real trouble. If anyone at the property is allergic, a single incident can be an ambulance call. Even “safer” DIY approaches, blocking the entry, burning the nest, putting a bag over it, tend to make things worse. Wasps that can’t get in through the main entry will chew a new one somewhere else, often into your loft. ## What we do ![Technician in full protective suit treating a wasp nest at the roof eaves](/images/misc/technician-in-full-protective-bee-suit-treating-wa.webp) Professional wasp nest removal [/wasp-removal-surbiton/ →](/wasp-removal-surbiton/) is one of the quickest jobs we do: 1. **Locate the nest safely** from a distance and identify the flight-path entry point. 2. **Kit up properly**, full protective suit, respirator, and correct-length extension pole so we can treat without being anywhere near the nest. 3. **Apply insecticidal dust** at the entry point. Returning workers carry the dust deep into the nest and the whole colony dies inside a few hours. 4. **Remove or make-safe** the nest, depending on location. Accessible nests are usually removed. Cavity or deep-loft nests are typically left in place, they can’t be re-colonised once dead. Most wasp jobs take 20-30 minutes on-site and the colony is dead by the next morning. ## When to call rather than wait - **Any nest near a doorway, garden or business entrance.** The proximity is what causes stings. - **Any household with someone allergic.** Even a small nest is a real risk. - **Anything above head height that you’re tempted to reach with a ladder.** Don’t. Call instead. - **Nests in a commercial premises** where wasps might reach staff or customers.
