Why Are Wasps Flying Into Your Great Preston Home? Common Causes and Solutions
When wasps turn up in bedrooms, hallways or bathrooms with nothing to tempt them, the nest may be in the structure of the house itself. This guide explains the signs.
When the wasps are coming from inside the structure
Wasps flying into the house from outside have one explanation. Wasps appearing inside a room with no open window, no food and no obvious way in have another: there is probably a nest within the building, and the colony has found, or made, a way through to your living space.
This happens when a nest is built in a cavity wall, behind a fascia, in the roof void, under a bath panel, in a chimney breast or in an old air brick. The workers leave through an outside entrance. Now and then a few lose their bearings and follow a gap inward instead, along a pipe run, a cable hole, a light fitting or a crack where a ceiling meets a wall. They then appear in the room, often by the window, looking for the way out.
It is an alarming experience, but it is also the clearest of all signs. Strays do not come out of ceilings. Nest workers do.
If you are not sure whether what you are seeing is a nest or simply a cluster of strays, give it a day or two and keep a note of the room, the time and the number. A real nest keeps producing wasps in the same spot.
Clues that point inside the building
Look and listen for these signs:
- Wasps emerging from a light fitting, a vent, a socket, the edge of a ceiling or a gap beside a window frame.
- A faint scratching, rustling or buzzing from within a wall or ceiling, often louder on a warm afternoon.
- A brown or damp-looking stain spreading on plaster, which can occur when a nest is large and close to the surface.
- Wasps that keep arriving in the same room day after day, however well you tidy up.
- A steady line of wasps visible outside, entering a small gap under the roof edge, at a soffit, behind guttering or at a brick vent.
- Dead wasps accumulating on a windowsill, in a light shade or beside a skirting board.
Count what you see over a few days. A strong nest only grows through the summer, and a colony that is sending a handful of wasps into the house in June may be sending dozens by August, when numbers peak and a nest can hold 2,000 to 10,000 or more wasps.
What not to do
The temptation is to act on the spot. Please don't.
- Do not seal the hole that the wasps are using. Wasps that can no longer leave through their normal exit will look for another, and that alternative may be through the plaster and into a bedroom.
- Do not poke, drill or hammer at the wall. Vibration and noise alarm the colony.
- Do not use smoke, water or home remedies at the entrance.
- Do not stand in front of the entrance to watch. A wasp defending its nest will target the person closest.
- Do not let children or pets play near the affected wall.
Instead, keep the doors of the affected room shut, put a towel along the bottom of the door if wasps are coming under it, and open the window if you need to let a trapped wasp out. Make a note of which rooms are affected.
Looking after the household in the meantime
While you wait for a visit, take sensible precautions. Check bedding and clothes before you put them on if wasps have been appearing in a bedroom. Keep shoes by the door so you can shake them out. Do not sleep with a window open beside a wall where wasps are entering.
If someone is stung, wash the area, remove the sting if you can see it and use a cold pack. Look out for signs of a serious allergic reaction, such as swelling of the face, lips or throat, wheezing or difficulty breathing, dizziness or a widespread rash. If any appear, call 999. A person who knows they are allergic should talk to their GP.
It is a good idea to tell the family why they should avoid the area, and to explain that a wasp in the bedroom is not a reason to panic, only a reason to move away calmly and shut the door.
If you rent, check your tenancy agreement and tell your landlord or agent about the nest. What you are each responsible for depends on that agreement, so it is best to check it rather than assume.
Shut the door of an affected room before you go to bed, and check that the gap under the door is covered if wasps have been appearing close to it. In the morning, open the window before you open the door, so any wasps in the room can leave without heading for the rest of the house.
How the visit works
A technician will want to know where you have seen the wasps going in and coming out, which rooms are affected, and whether anyone at home is allergic to stings. Photographs of the outside wall, roof edge or vents, taken from a safe distance, can help when you describe the problem.
