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

A conservatory or porch is a bright, warm space that wasps find just as appealing as you do, and it has more small gaps than most rooms.

Warm rooms attract early visitors

Glazed extensions heat up fast on spring days. For a queen emerging from winter sleep, a conservatory is a sun trap with windows to bang against, plenty of ledges and gaps in the frame. It is common to find a large, slow wasp on the glass in April or May, and it is almost always a queen who has wandered in.

She is not returning to an old nest. The wasps that built last year’s nest, wherever it was, died in the autumn. She is a young queen who survived the winter and is looking for somewhere new.

For households in Sturmer with a conservatory, porch or garden room, the sensible response is to let her out and then look at how she got in.

Rooms that are kept closed through the winter, such as a seldom-used conservatory, are particularly likely to have a sleeper that wakes in the first sun.

Ways in

Glazed structures have many joints: where the roof meets the house wall, where the frame meets the base, where vents and trickle vents open, and where the roof bars meet the gutter. Any of these may have a small gap. Door seals worn through use and windows that no longer close fully are other routes.

• Roof joints and the line where it meets the house.
• Vents in frames and glazing bars.
• Worn brush strips on doors and windows.
• Gaps around pipes and cable holes.

Look at them on a bright day from inside, when daylight through a gap is easy to see.

Check also the window furniture. Hinges, stays and the gaps around handles can open slightly as seals age, and the hollow sections of uPVC frames sometimes have drainage slots on the outside that are a size a wasp can use. A small piece of mesh over a drainage slot, fitted by a glazier, helps without blocking drainage.

Look at the junction between the conservatory base and the garden too. Soil that has washed away, or a crack in the base, offers a route to the space under the floor.

Gently showing a queen the way out

Do not swat. Open the nearest door or window as wide as it will go, close the others, and turn off any lights, so that the brightest place is outside. Give her time. Most queens find their way out within minutes.

If she is stuck on glass, a cup and a piece of card will move her safely, as long as you take care not to trap her against your hand. Release her outdoors, away from the door.

If wasps keep appearing, day after day, you may have a nest in the structure, such as in the roof cavity above the glazing, or in the wall where the extension meets the house.

Keep the exit route clear of obstacles and tell children and pets to stay out of the room until she has gone. If she lands on you, stay still and let her fly off. If a sting happens, wash it, remove the sting if visible and use a cold pack. Dial 999 if there is swelling of the face, lips or throat, wheezing or breathing difficulty, dizziness, or a widespread rash.

Nests in the fabric of the room

Porches and garden rooms often have a hollow roof or a boxed-in eave, and these are cavities. A steady line of wasps entering a joint in the outer frame, or buzzing from the ceiling, indicates a nest. Stay out of the room if you can hear it, and keep the door closed.

Do not seal the gap or spray into the cavity. Wasps blocked from one exit will look for another, and it may be inside the room.

Old nests found in these spaces in winter can be bagged if you can reach them safely and are sure they are empty.

If the room is part of a business, such as a showroom or a waiting room, post a short note for staff explaining what to do. Customers should be moved away from the affected area calmly, and no one should attempt to clear a nest.

Where the room is rented, report the problem to whoever manages the building, as repairs to the structure depend on your agreement.

Keeping the room comfortable

In summer, wasps are drawn into conservatories by food and drink. Cover food, clear plates promptly and keep bins outside. Fit fly screens to openable windows if your frames allow, and replace worn brush strips on doors.

Blinds and curtains can hide a wasp until you move them, so shake them out before closing in the evening, standing well back.

Do not forget the ledge above doors and the top of curtain rails, as queens like to sit high. A brief look each morning in April and May is plenty.

Roof blinds that are left drawn all winter can also hold a queen in the folds.
