Why Are Wasps Flying Into Your Chapeltown Home? Common Causes and Solutions
Chimneys, air bricks and small gaps in the walls can all become wasp doorways, and this guide shows how to find them safely and what to do next.
Wasps from the fireplace
You are tidying the living room when you notice a wasp crawling across the hearth. It did not come through the window, which is shut, and it did not follow you in from the garden. Later that day there is another, and the sound of a faint buzz seems to come from behind the fire surround.
This is one of the more unsettling versions of the problem, because the wasps are arriving from inside the structure of the house. The direction they come from is the useful part. A chimney, a flue or a wall cavity is a sheltered, dry, undisturbed space, and from late April onwards a queen looking for a nest site can find it attractive.
Wasps in this situation tend to show up in rooms that share a wall or chimney breast with the stack, and that is the pattern to keep in mind. If the visitors are always in the same room near the same chimney breast, it is likely that the colony is close.
For a household in Chapeltown, or anywhere else, understanding how wasps get into the walls is the first step to deciding what to do.
The gaps wasps use
Wasps need only a small opening. They squeeze through spaces that look too tight to bother with, and then work inwards to a cavity where the nest can grow. Typical entrances include:
- a chimney pot or stack that has no cap or has a damaged one
- air bricks and ventilation grilles with broken or missing mesh
- gaps where pipes or cables pass through a wall
- loose or missing mortar joints
- gaps under eaves, fascias, soffits and bargeboards
- the edges of roof tiles and ridge lines
- gaps around window frames or the joins between extensions and the main building
Once a colony is established, workers may use the same entrance, but they may also push through to another opening. That is how a nest in the cavity ends up producing wasps in the hearth, in the airing cupboard or beside a radiator.
Checking safely from the outside
A careful look from the ground is enough. Choose a warm, calm day when wasps are active, and stand a good distance back with a clear route behind you. Look at each wall in turn, then up at the roofline and the chimney. You are searching for a single spot where wasps appear to land, walk in and fly out again, again and again.
Binoculars help a good deal if you have a pair, because they let you see detail without getting close. Notice the height, the side of the house, and whether the entrance is at the chimney, the eaves or a lower air brick. Do not put a ladder against the wall to take a closer look.
Write down what you see. A short note of the time, the weather and the position of the entrance is helpful when you speak to us, and it saves you having to keep going back out to watch, which would otherwise bring you closer to the nest than is sensible.
Inside, avoid pulling off fire surrounds, panels or ceiling boards. If a nest is behind them, opening up the space releases angry wasps straight into the room.
Why blocking the hole is a mistake
It seems logical to stuff the gap with filler or tape to stop the wasps. Please do not. The colony inside still needs to come and go, and if the exit is shut, the workers look for another way out. They are very good at finding it, and it is as likely to lead into a room as to the outside.
A sealed entrance also traps a large number of wasps close to your living space, at a time when they are at their most agitated. If the opening is already inside the house, close the door of that room, place a towel at the base, and keep people and pets out.
Fire grates and flues are worth a special mention. If you have an open fire or stove, do not light it to try to drive out the wasps. Leave it alone, and tell us about it when you book.
When the colony is at its peak
Nests begin small, but a colony grows through the summer and reaches its peak in August. It can hold 2,000 to 10,000 wasps or more by then, and the amount of traffic at the entrance reflects that. A house with a nest in a chimney or wall in July may see several wasps in the house in a day. By late summer the number can feel overwhelming.
If you are not sure of the signs, think about duration and direction: wasps that arrive from the same spot day after day, and appear in the same rooms, indicate a nest. Isolated wasps in odd places and at odd times do not.
Do mention it to the people you live with, and to neighbours if the nest might be on a shared wall. Everyone should know to stay away from the entrance and to keep doors and windows near it closed. If the property is rented, check your tenancy agreement for who arranges the treatment, as that depends on the agreement.
