Wasp queens build their nests alone at first, building their colony up as they head into summer. By July, a single nest will house several thousand wasps. Up to this point, they are generally uninterested in people.
From midsummer onwards, as the colony stops raising new larvae, the workers switch from hunting insects to sugar, leading them to aggressively pursue food, drinks, and bins. The same nest in March and August is a different scale of problem entirely.
Shop sprays are repellents, not killers. They can’t penetrate deep into the nest. All they serve to do is agitate the surrounding wasps, causing them to release pheromones that signal the rest of the nest to defend it, aggressively.
Blocking the entrance doesn't work either. The colony will find or chew another way out, and if the nest is in a loft or wall cavity, that exit may be into the house itself.
A wasp sting can cause anaphylaxis, and some people don't find out they're allergic until a second or third sting. If that's a possibility, don't approach or investigate the nest. Call a professional straight away and keep everyone else away until it's been treated.

We treat the nest directly, applying insecticide into the entrance with products built to spread deep into the structure. Most jobs take under an hour. The empty nest can be safely removed once the colony has died off, usually within a day or two, but once it is dormant, it will not be reused.
Unlike other pest control companies, we don’t charge per visit. Instead, we provide a fixed and fair quote for the problem, regardless of how long it takes, keeping us accountable to fixing the problem for good.

Activity builds through late spring and peaks between July and September, when colonies are at their largest and most defensive. Nests treated earlier in the season are smaller and easier to deal with, so if you've spotted one forming, act quickly. A nest left until August is a much bigger job than one treated in May.
Wasps don't reuse old nests, but they are drawn to the same structural features that made a spot appealing in the first place. If the entry point is left open, a new queen may choose the same location the following spring. We can advise on simple proofing measures after treatment to make that less likely.
We apply an insecticidal dust or spray directly into the nest entrance. Returning workers carry it through the nest, and activity typically stops within 24 to 48 hours. In most cases the physical nest doesn't need to be removed. Once the colony is gone, the nest is inert; wasps will not use it.
Absolutely not. Disturbing a nest without the right equipment and treatment can trigger a fast, aggressive defensive response, and unlike bees, wasps can sting repeatedly. The risk is serious, especially if you or anyone nearby has an allergy. Professional treatment is faster, safer, and considerably more reliable than anything available over the counter.
The surest sign is a steady stream of wasps flying to and from a fixed point: a gap in the eaves, a soffit, an airbrick, or a hole in a wall or fence post. You might also hear a low, continuous buzzing from inside a wall or ceiling. Seeing 20 or more wasps around the property on a regular basis is a strong indicator there's a nest nearby, even if you don't know where.
