Wasp Nest in a Cavity Wall – How Professionals Treat Hidden Nests in Upnor
You do not need to have found the exact hole before you call, because locating the working entrance is part of the technician's job on arrival.
You do not have to be the detective
Many householders hold off calling because they feel they should first pin down exactly where the nest is. That is understandable, but it is not necessary. A technician's first task on arrival is to find the entrance the wasps are actually using, and your description simply gets them to the right part of the building.
For a household in Upnor, on the River Medway, a call can be as simple as: wasps are going into the wall on the left side of the house, about as high as the first-floor window. That is enough. The rest is done on site.
What helps most is honesty about what you do not know. If you have not seen the hole, say so. If you think there might be two, say that too.
The technician will also consider the surroundings when judging the safest way to work, for instance where people and pets might be and which windows need to stay closed. It all happens in the first few minutes of the visit and is part of the service rather than something you pay extra for.
Looking before touching
The technician starts by standing back and watching. This is the same patient approach that works for a householder, but with experience behind it. Watching the flight of wasps for a short while shows where they come and go, and a quick look along the wall reveals gaps, vents, damaged pointing and cable holes that might be in use.
They will also look for secondary routes. A nest in a cavity can have more than one way in and out, and knowing about them helps plan the treatment properly. If wasps are already coming indoors, the technician will want to know which rooms are affected.
None of this requires you to be on the spot. Indeed it is better if you are indoors, at a distance, or elsewhere on the property.
Experience helps here because certain patterns repeat. Wasps tend to favour entrances that are sheltered from wind and warmed by the sun, so a south or west-facing wall deserves a closer look. That does not mean a nest cannot be elsewhere, only that the starting point is sensible.
What you might be asked
Expect a few straightforward questions before work starts. They are not a test. They help the technician make safe decisions.
- Which wall did you see the wasps on, and how long has it been going on?
- Has anyone blocked, sprayed or knocked the wall?
- Is anyone at home allergic to stings?
- Are there children or pets who might be outside?
- Is there easy access around the wall, such as a gate or a clear patch of ground?
Answer as fully as you can. If a family member is allergic, we would have preferred to know at booking, as it allows prioritisation, but say so on the day if you forgot. It changes how everyone stays safe during the visit.
Treating the nest from the entry point
Once the entrance is confirmed, the nest is treated through it. This is the standard approach for a hidden nest, and it is why the wall does not need to be opened. We make no claims about specific methods, since each situation is a little different, but the principle is that the entry point is the route to the nest.
The technician is fully insured and qualified, and works carefully around the wall. You will be asked to keep windows closed on that side of the house and to keep people and pets away until told it is safe.
After the work, the technician can tell you what to expect over the following days, including the possibility of stragglers near the wall for a short time, and what to do about sealing.
It is worth saying that every property is different, and so we avoid giving promises about the exact procedure before a technician has seen the wall. What we can say is the price and the principle: one fixed fee for the nest, treated from the entry point.
Price and booking
The price is £120 per nest, fixed, with one visit guaranteed and no call-out charge. It does not change with the time of day or location. If a second nest is found on the property, the additional one costs £60 extra.
At booking, you can ask whether the empty nest can be taken down afterwards. That depends on the position of the nest and is something the technician can explain on arrival.
To arrange a visit, call 01622 410 019 or use the online form on the contact page. We work seven days a week, same-day service is offered, and evening and weekend appointments are available.
People sometimes ask whether they should be present throughout. You do not need to watch the work. Many customers prefer to stay indoors, and the technician will tell you when it is done. If you cannot be home at all, arrange for someone to give access to the wall and tell us in advance.
After the technician leaves
Keep an eye on the wall from a distance for a few days. Some wasps that were out foraging may return to the nest site, and you may see a few circling the entrance. If you see sustained activity continuing, contact us.
Wait for the wall to be quiet before sealing. A builder can fix pointing and fit mesh to vents once you are confident that nothing is entering or leaving. Sealing an active gap risks sending wasps inside.
Keeping a short note of what the technician said, including any other gaps they spotted, helps when you talk to the person doing the repair.
Do not be tempted to check the entrance yourself after the visit, even if it looks quiet. The wasps that were out foraging can return to find the nest gone, and they may hover for a while. A few days of patience is better than a sting.
