Do Wasps Return to the Same Nest Every Year? A Guide for Horndon on the Hill Gardens

The first large wasp of the year looks alarming, yet she is a lone queen with no colony, and what she does next is worth watching.

The wasp that arrives before summer

Every spring, long before there are wasps at the picnic table, a large wasp turns up in a kitchen, a conservatory or a shed. People often assume that the colony from last year is back. It is not. This wasp is a queen who survived the winter alone, and she is the whole of a future colony.

The workers from last year all died in autumn, along with the old queen, and the nest they built was abandoned. Only young queens, produced late in the season, hibernated. Each one is now waking up and looking for somewhere new.

If you live in Horndon on the Hill and see a big wasp in April, you are watching the very start of the cycle, not its return.

Queens are most often noticed on warm, bright days in April, but a cold snap afterwards can send them into hiding again, so a sighting does not mean a nest is under way.

What she is doing

A queen out in spring has two jobs: feeding herself and finding a nest site. She drinks nectar and sap to build up energy, and then she explores cavities. She may fly slowly, bump against windows and investigate sheds, eaves, holes and loft entrances.

You may see her enter and leave a gap several times. That repetition is the sign to watch. If she disappears into the same hole day after day, she may have found a site and begun building.

• Note the time and the exact spot.
• Watch from a distance of a few metres.
• Do not block the gap while she is inside.

Queens drink at flowers such as early blossoms and ivy leaves, and may be seen resting on warm walls in the sun. These are normal behaviours. You do not need to act unless she is repeatedly entering a gap.

A queen usually works alone, so any area with several wasps going in and out is already beyond the starter stage.

If she is in the house

Stay calm and let her find the way out. Open the nearest window wide, switch off lights in the room and shut the door to the rest of the house so that the brightest exit is outside. A glass and a piece of card can catch her if she is stuck on a pane, as long as you do not squash her against your hand.

Avoid swatting. A cornered insect may sting, and a squashed queen releases alarm signals. She is not aggressive by default, and in most cases she is simply lost.

If wasps keep appearing in the same room over days, that points to a nest in the building and is no longer a stray queen.

Keep pets away from her too, since dogs and cats often chase a slow insect and get stung on the nose or paw. If a pet is stung and the face swells or it seems unwell, contact a vet.

If you work from home, check that window frames have no gaps leading into the room, and use fly screens if they suit your windows.

The starter nest

When a queen settles, she chews wood fibre and builds a tiny nest, often no bigger than a walnut, with a few cells. She lays eggs herself and feeds the first grubs. When those first workers emerge, usually late May or June depending on the weather, the colony starts to expand quickly.

This is the best moment for treatment, because the colony is small. But even a starter nest should not be disturbed. Leave it, mark the position and ring for help.

Do not knock it down. The queen is likely to rebuild nearby.

Common starter sites include under eaves, in sheds, in air bricks, in lofts and in holes in the ground. A starter nest in a sheltered place may be invisible from outside, which is why the behaviour of the queen is the more reliable clue.

Old nests are no help to her

One thing a queen does not do is use last year’s nest. Old paper is brittle and dirty, and it is not a ready-made home. If you have an old nest in a shed, it may still be there when she arrives, but she will build fresh.

You can bag an old nest once you are sure it is dead. Ask the technician whether an empty nest can be taken down when you book a treatment for a live one.

Late in the year the colony makes new queens, and these are the wasps that hibernate. Each one finds a dry, sheltered spot, such as a gap in a wall, behind bark or in a pile of leaves, and waits until spring. The old queen and all the workers die. The cycle then starts again with each young queen picking her own site.

That is why a garden can seem to have a sudden outbreak in spring. It is really many separate queens making separate choices.
