How to Tell If You Have an Active Wasp Nest on Your Lindhurst Property
Wasps can nest in chimneys, vents and airbricks. Learn the signs of an active nest in these spots at your Lindhurst property and what to do.
Openings that lead somewhere
A chimney, a vent or an airbrick is, to a wasp, a doorway to a sheltered space. It is dry, it is dark and there is often a good deal of room inside. A queen that finds one in spring may start a nest a short way in, and the colony grows into whatever cavity it finds.
In Lindhurst, in Nottinghamshire, a house with a chimney that is not in use, a loft vent or a row of airbricks has several of these possible entrances. Knowing how to read them makes it easier to tell a nest from a few visiting wasps.
The common thread is that all these openings lead to hidden spaces. You will rarely see the nest, only the traffic, and that is enough. A nest does not need to be visible to be real.
Chimneys
A disused chimney with an uncapped pot is open to the sky, and a queen can drop in and start building on a ledge inside. The nest might sit above a fireplace that is boarded up, or directly behind the plate in a room. Wasps may come into the room through gaps in the fireplace cover.
- Wasps landing on the pot or the top of the stack and going in.
- Wasps coming out of a fireplace, or buzzing behind a blanking plate.
- A hum from the chimney breast when the room is quiet.
- Small grey scraps or debris in the grate or hearth.
- Wasps collecting on a window in the room with the chimney.
Do not light a fire to try to drive the wasps out, and do not poke up the chimney. Both are dangerous, and the first can cause other problems.
Airbricks and wall vents
Airbricks let air into the space under floors and into cavities. Over time the grille can crack or go missing, and a wasp can enter. The nest will be inside the void, so the only external sign is wasp traffic and perhaps a stain on the brickwork.
Look at each airbrick from a distance. A busy one will show wasps landing on the grille and slipping through a gap, or a thin stream of insects along the wall. You might notice an odd hum from a downstairs room or from the floor, which carries through the void.
Tumble dryer and extractor vents are a similar matter. A flap that no longer closes properly is an open invitation, and the first sign may be wasps in the utility room or bathroom.
Loft and roof vents
Vents at the gable ends or the soffits of a roof lead directly into the loft. A nest in the loft may be built on a rafter or in the insulation. The wasps travel through the vent, and you might see a stream at the top of the wall, or you might hear them from a bedroom ceiling.
Go outside and look up at each vent. A moving line of insects at a single vent is what you are after. Compare with the other vents on the building. If only one is busy, that is the entrance.
Do not climb into the loft to look. The nest may be near the hatch, and opening it can release a large number of wasps into the house.
Gable-end vents are the easiest to check because the wasps are silhouetted against a plain wall. Pick a bright morning and watch for a few minutes from the garden.
Telling a nest from a lost wasp
Not every wasp at a chimney or vent is a sign of a colony. A wasp may land on a pot to rest, or a scout may check a vent and move on. The difference is persistence. A nest has traffic that carries on for hours, and the wasps do not hesitate once they have found the gap.
Try this simple test. Watch the opening for five minutes. If one or two wasps visit and leave, it is probably not a nest. If you can count ten or more going in, and others coming out, treat it as active. If you are unsure, repeat the watch on another warm day.
Inside the house, the equivalent test is the room. A wasp or two near a fireplace on a hot day is odd but not alarming. A cluster of wasps on the window of the room, appearing every day, means that something is feeding them in.
Seal nothing until the wasps are gone. Once the nest has been treated, a chimney cap, a mesh over an airbrick and a properly fitting flap on an extractor vent are all sensible measures against next year's queens, and a builder or roofer can fit them.
What to do about it
Do not block any of these openings while wasps are using them. They will find another way out, which might be into the room. Keep the door of the nearest room closed and avoid using it.
After treatment, ask the technician whether the openings should be sealed and whether the empty nest can be taken down. Tell us at booking which opening you think the wasps use and which room you hear them in.
