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

A wasp colony lives for a single season, so last year's nest is never reoccupied, but a new queen may well choose a spot very close by.

The short answer: a nest lasts one season

No, wasps do not come back to the same nest. Each paper nest is built from scratch in spring, grows through the summer, and is abandoned when the colony dies off in autumn. The nest you find hanging in a garden shed in November is a leftover shell, not a home that is waiting to be refilled.

That surprises many people, because wasps do seem to turn up in the same corner of a garden year after year. The explanation is not loyalty to a building. It is that the same features that suited one queen tend to suit the next, and we will come to those further down.

If you live in Galleywood and are staring at an old nest wondering whether the whole thing starts again, the reassuring part is that the colony inside it is already finished. The part that deserves your attention is what a fresh queen might do in the spring.

How the year unfolds for a colony

The story starts with a single queen. She spends the winter tucked away in a sheltered, dry crevice, then comes out when the weather warms, usually from late April depending on the season. She chooses a site, chews wood fibre into pulp and builds a small starter nest, laying the first eggs by herself.

Once those first workers hatch, they take over the building and feeding, and the queen stays inside laying. The colony then grows steadily. By August it is at its peak, and a nest can hold anywhere from 2,000 to 10,000 or more wasps.

After that the cycle turns. Late in the season the colony produces new queens, the old queen and the workers die, and the nest is left empty. Only the new queens go on to shelter for winter, and each of them starts a different nest of her own the following spring.

Why the same spot can be chosen again

A queen is looking for a protected cavity that is dry, dark and out of the wind. A gap behind a fascia, a void in a wall, a hollow in a bank or the underside of a shed roof can tick every box year after year, which is why a second nest sometimes appears within sight of the first.

It is worth being clear about what this does and does not mean. The old nest itself is not being reused, and there is no strong evidence that a leftover shell draws queens in. The shell is simply evidence that the location is attractive, in the same way a well-sheltered corner is attractive to many creatures.

• Keep note of exactly where last year’s nest was found.
• Look at that spot again in late spring.
• Check nearby gaps of a similar kind, not just the identical one.

What to do with an old nest you can see

An empty nest from last year is not dangerous, because the colony has gone. Even so, be sensible. If you are not completely certain that it is old, treat it as live and keep away; nests found in October can still hold wasps, and a quiet-looking nest in a warm spell may not be as dead as it seems.

Check by watching from a distance for a few minutes on a mild day. If nothing comes or goes at the entrance, and it has looked the same since the first frosts, it is almost certainly abandoned.

You can ask the technician at booking whether an empty nest can be taken down, since that is a separate question from treating a live one. If you leave it, it will simply weather away. Do not poke it, shake it or burn it, and do not seal an entrance if there is any chance of activity.

Common mix-ups that cause worry

Several things get mistaken for a returning nest. A single wasp in the kitchen in March or April is nearly always a queen coming out of hibernation, searching for somewhere to build, and not a sign that a colony is already established in the house. Likewise, a cluster of wasps on a window in October is usually a group of late foragers and not a hidden nest.

Another mix-up is confusing a leftover nest with a fresh one. Old nests turn grey, brittle and ragged, while a live nest looks tidy, has a steady flow of traffic at one entrance and often looks slightly shiny with fresh paper. If you can see traffic, it is live.

Finally, some people expect the same address to be hit every year. It can happen, because a good cavity is a good cavity, but it is not a rule, and plenty of gardens see a nest one year and none the next.

Getting ready for next spring

The best protection is attention. In March and early April, walk the outside of the house, the garage and any outbuildings and look for small gaps in eaves, brickwork and timber. Fill the ones you can reach safely, and make a note of the ones you cannot.

From late April, glance at likely spots every few days. A single large wasp investigating a gap repeatedly is probably a queen, and an early starter nest is far easier to deal with than a summer-sized one.
