Wasp Nest in a Cavity Wall – How Professionals Treat Hidden Nests in Woodhouse Eaves
When wasps start turning up inside a room with no open window, a nest in the wall behind it is a likely cause, and the room needs treating with care.
A wasp in the room, and another, and another
One wasp indoors is ordinary. Three or four in a morning, in the same room, with the windows shut, is a pattern. If they seem to appear near the same wall, or if you notice them walking out of a gap around a skirting board, a socket or a light, you may have a nest in the cavity and a way through from it.
This is the point at which many people feel alarmed, and that is understandable. The calm response is to treat it as a sign that the colony has found a route into the building, and to arrange professional help rather than deal with each wasp one at a time.
It can help to count. Note the date, the room and how many wasps you see over a day or two. That gives a clear picture of whether the numbers are rising, which in a growing colony they usually are through July and August.
Where wasps tend to come through
In a wall void, wasps follow whatever gaps they can find. Inside the house these are most often the following.
- The edge of a skirting board or the gap between board and plaster.
- Around electrical sockets, switches and ceiling roses.
- Where a pipe or cable passes through a wall or floor.
- Around extractor fans and wall vents.
- The junction between wall and ceiling, especially on an outside wall.
If you find wasps at one of these spots, make a note and photograph the area without getting close. The location tells the technician a great deal about how the void connects to the room.
Rooms with warm outside walls, or on the sunny side of the house, tend to be where trouble begins first, since warmth draws wasps through gaps. This is general, not a rule, so look at all the walls.
What to do in the room
- Stay calm and move people and pets out of the room if you can do so without disturbing the wasps.
- Close the door and, if the wasps can see it, give them a way out by opening a window on the far side of the room.
- Do not swat at the gap. Wasps that are crushed or agitated near a nest can excite others around them.
- Do not stuff the gap with tissue or tape. Wasps will find another point.
- Keep a note of how many you see and when, and call to book a visit.
Do not use electrical sockets that have wasps coming out of them until the problem has been dealt with, since a nest behind a socket is not a safe place for fingers or plugs.
It is natural to want to deal with each wasp quickly, but a cup and card is the only sensible tool, and only if you are confident. For anything more than one or two wasps, step back and let the room settle.
Why the room and the outside both matter
A breakthrough inside the house means the colony has a route to the inside, but it does not mean the wasps entered the house that way. There is nearly always an outside entrance too, perhaps a gap in the brickwork, a vent or a hole at the roof edge. The wasps coming indoors are often the ones that took a wrong turn within the void.
In Woodhouse Eaves, as anywhere, the technician will look at both. They will find the busiest outside entrance and treat the nest through it, because that is the route the colony is actually using. Dealing with the outside is what stops the stream into the room.
Our technician will not ask you to remove anything from the walls inside. They may ask you to move furniture a little so they can see the skirting or socket you mentioned.
What happens when the technician arrives
The technician will ask where you have seen wasps indoors, then check the outside of the wall and watch the flight line. Once they have confirmed the entrance, the nest is treated through it. There is no need to cut into the plaster or remove fittings. They are trained, and the work is fully insured.
We do not set out the treatment method on this page, but you can ask questions on the phone. If you wonder whether the empty nest can be taken down afterwards, raise that when you book.
A few wasps may still be around for a short time. Keep the room closed until the technician says it is fine to go back in, and then deal with any stragglers by letting them out through a window.
Booking and what it costs
Treating a wasp nest costs a fixed £95 per nest, and an additional nest on the same property is £35 per nest. There is no call-out charge, and the price is agreed by phone before anyone attends. Call 0116 214 9259 or use the contact page booking form. We are open seven days a week, offer same-day service and work for both homes and businesses.
If anyone is allergic to wasp stings, tell us at the time of booking. Once the nest is treated, a repair to the gap that let the wasps indoors will help stop a repeat.
Inside the house, a thorough clear-up afterwards is worthwhile. Dead wasps can still sting if trodden on barefoot, so sweep them up and bin them promptly.
People sometimes worry that a room which has had wasps in it is unsafe afterwards. Once the technician has treated the nest and the activity has stopped, the room is safe to use again, and there is nothing to disinfect or throw away.
