Do Wasps Return to the Same Nest Every Year? A Guide for Aylesford Gardens
An empty paper nest turning up in the autumn clear-out worries many householders, but wasps do not move back into last year’s home, and there is a sensible way to deal with it.
The nest you found is finished with
The usual way people meet an old wasp nest is by accident. You go into the shed to put the mower away for winter, or you cut back a hedge, and there is a grey, papery ball the size of a football that you have never seen before. It looks like something that must have been there all summer, and it probably was.
The short answer to the question in the title is no. Wasps do not return to the same nest each year. A colony lives for a single season. Once the cold weather arrives, the workers die off, the nest stops being used and it is simply left behind. The paper shell stays where it was built, but nobody lives in it any more.
That is why an empty nest in Aylesford, near Maidstone, or anywhere else is not a sign that the wasps are coming back to the same address. It is a leftover from a colony that has already ended.
Check the nest’s condition and you can usually tell its age. A fresh, firm shell with a crisp, layered texture was probably in use quite recently, while one that has turned brittle and pale has been abandoned for a good while. Either way, the point stands: the colony has finished.
What happens to the colony in autumn
A nest starts small in spring and grows through the summer. By August it can hold anywhere from 2,000 to 10,000 wasps or more. After that point the colony begins to wind down, and by late autumn the workers have died.
The only wasps that survive the winter are the new queens that have mated. They leave the nest, find a sheltered spot to rest through the cold months and emerge when the weather warms. Each one then looks for her own place to start a new nest from late April, depending on the weather.
This explains something that confuses people. A new queen does not go back to the old paper shell. She starts again from nothing, building a small first nest and laying eggs herself. If she picks a spot close to last year’s, it is because that sort of place suits wasps, not because she remembers it.
Think of it as a relay with no baton. Nothing is handed from one season to the next except the queen’s ability to start again, and she does that from scratch, usually somewhere you would not expect.
Why a similar spot sometimes gets chosen again
Many homeowners are certain that “the wasps came back” because a nest appears in nearly the same place two summers running. The reason is practical rather than mysterious. A gap under the eaves, a hole in a wall, a dry corner of an outbuilding or an old burrow is attractive to any queen looking for shelter, and the same features tend to stay in place from one year to the next.
So the nest is new, but the opportunity is old. If you want to reduce the chance of a repeat, your effort is better spent on the spot than on the empty nest.
An old nest can also catch the eye of people passing, and it is easily mistaken for a live one. That is a good reason to deal with it sensibly instead of leaving it to cause alarm.
It is worth thinking about this as a risk to manage rather than a certainty. Some years a promising gap will stay empty. Other years a queen will find it within days of the weather turning warm. Because nobody can predict which, a quick check in spring is much more reliable than hoping.
What to do with the old nest
Be sure it is really empty before you touch it. The best time to judge that is when it is properly cold, with no wasps seen coming and going for a good while. A nest that was active only a short time ago can still have a few wasps on it, and they can sting if disturbed.
If you are not certain, leave it alone and ask for advice. If the nest is clearly dead and out of reach of your family, there is no harm in leaving it where it is until you are ready to clear it. If you want it gone, wear sturdy gloves and long sleeves and put it straight into a bag.
When you book an appointment for any live nest, you can ask the technician whether the empty nest can be taken down. We would rather you ask than guess.
Do not be tempted to burn, hose or smash a nest that you think is empty. If it is not empty, you have made a very bad day for yourself, and if it is, you have achieved nothing that a bin bag would not have done more safely. Keep children and pets out of the area while you work, and wash your hands afterwards.
Making your garden less appealing next spring
You cannot stop a queen from looking, but you can give her less to work with.
- Fill or block gaps in outbuilding walls, fascia boards and soffits once you are sure nothing is living there.
- Keep the shed door closed, and check that window frames and vents are intact.
- Fill in disused burrows and holes in banks and lawns once the weather has turned cold.
- Clear out stored boxes and old cushions from sheds and garages, which make good nesting material and corners.
- Keep compost heaps and bins covered.
Carry out these jobs in winter or very early spring, and never seal a hole that might have wasps going in and out of it.
Be realistic about the aim. These measures lower the odds and make any new nest easier to notice, but they cannot promise that no queen will ever try your garden. A neighbouring property may well have its own nest, and wasps forage widely, so seeing a few wasps in summer does not by itself mean a nest is on your land.
Checking again from late April
Put a reminder in your diary for late April or early May. On a mild day, stand back and watch your usual trouble spots for ten minutes. A single wasp circling is normal in spring, but one that keeps flying into the same gap is probably building.
A nest caught early is much smaller and simpler to deal with than one found in August. If you find a live nest, do not go near it.
