Do Wasps Return to the Same Nest Every Year? A Guide for North Shoebury Gardens

Air bricks and cavity openings let wasps into the wall itself, and a winter walk-round shows which ones deserve attention before spring.

A nest you never saw

Some nests are never seen, and the first clue is wasps disappearing into a small opening low on a wall. Air bricks are designed to let air under floors and into cavities, and the slots are just the right size for a wasp to slip through. Behind them the cavity can be dry and dark, and there may be plenty of room.

If wasps used an air brick last summer, the colony has since died and the nest has been abandoned. Nothing will move back in. But the opening is still there, and it is a good example of the kind of place that gets picked again by a new queen.

Residents in North Shoebury and elsewhere often ask whether they should worry about the old paper left inside. The answer is that it does no harm sitting in a cavity, and trying to dig it out is usually more trouble than it is worth.

Brick and mortar are not the only way in. Cavity vents, small cracks beside window frames and places where a boiler flue or an extractor passes through the wall can all lead to the same sort of space. A thorough look at the whole building once a year, in the cold months, is the best preparation.

Reading the outside of the wall

The evidence is usually on the surface. Look at the area below an air brick or a gap in the mortar for small dark stains, grey fibres or dead insects on the ground. A line of tiny, regular scratches on the brick is often the track of chewing wasps taking material for paper.

Check air bricks on every side of the house, not only the one you see most.
Look at weep holes and gaps around service pipes.
Notice damaged brickwork where mortar has fallen away.
Check outbuildings and the garage walls too.

Do this in daylight on a cold day, when nothing is flying, and you can look closely without any risk.

Covers, mesh and ventilation

Air bricks are there for a reason, and blocking them can cause damp, so the answer is not to fill them. A fine mesh fitted across the opening lets air move but stops insects crawling in. Some air bricks already have a grille, and a damaged one is the weak point.

Ask a builder to fit or replace covers properly. If you rent, your tenancy agreement will say who deals with repairs, so check it and report the problem to the person responsible. Do not do structural work that you are not permitted to do.

Choose a cold period for the work, so that nothing is inside, and avoid covering an opening that is still in use during the warmer months.

Fittings made of plastic are lighter and cheaper than metal ones, but they can crack with age and sun, so look at them closely and replace any that are brittle. Metal grilles can rust and leave larger gaps than their design intends.

Ask whoever fits them to leave the airflow clear, because the point is to keep insects out without causing a different problem with moisture under the floor.

What if wasps are in the wall right now?

A live nest in a cavity cannot be reached or removed by the householder. If you see traffic at an air brick or hear a rasping, scratching sound from within a wall, step back and keep everyone away from the area. Do not plug the hole, because wasps can find another exit, sometimes through a gap in the room inside.

Close doors and windows near the area if wasps start to appear indoors, and keep an eye on light fittings and skirting boards, where they sometimes emerge. Never spray into an opening or pour anything down it.

If you can see the entrance, tell us roughly where it is and how high up, which helps the technician arrive prepared.

Remember that a nest within a wall may be very large by August, with workers arriving in a constant stream. The volume of traffic alone is a good reason to stay clear of the wall and not to stand beneath the entrance.

Keep washing lines, play equipment and seating away from the wall until the problem is dealt with.

The old paper and the next spring

Whatever is inside the wall now will decay over time. It cannot be reoccupied. If you want to know whether an empty nest can be taken down, ask the technician when you book, because the answer depends on where it is.

In the meantime, make a note of the location and check the opening again from late April, depending on how the weather behaves. A lone wasp probing the same hole several times is worth taking seriously.

Because queens choose independently, you cannot predict from last year which opening will be chosen. Several air bricks might look the same to us and different to her. That is why checking all of them is worth the effort, including those at the back or side of the house.

Frequently asked questions

Should I block an air brick that wasps used?

Not entirely, as air bricks need to let air through. A fine mesh fitted by a builder in cold weather is the usual approach.

Can wasps reuse a nest inside a cavity wall?

No. The colony dies in autumn and the nest is left to decay. A new queen would build her own nest.

Will an old nest in the wall cause damp?

It is not a known cause on its own. If you are worried about damp, ask a builder to inspect, and keep air bricks clear.
