Do Wasps Return to the Same Nest Every Year? A Guide for Harlington Gardens
Several widely held beliefs about wasp nests are wrong, and sorting fact from myth makes it easier to decide what to do with an old nest.
Myth one: wasps return to the same nest
This is the belief that prompted the question in the first place. It is understandable, because wasps seem to come back in huge numbers each year. In truth every nest is new. The colony dies in autumn and the structure is abandoned. A queen who has spent the winter in a sheltered hiding place begins a new nest in spring, usually from early April depending on the weather. What returns is the season, not the nest. If you have seen wasps in the same corner two summers in a row, the explanation is a similar site, not the same structure.
Think of it as a block of flats being demolished each autumn. The next resident does not move in, but another family may build a new house on the same plot. The plot attracts them, and it does so because it is dry, sheltered and quiet. If you remember that picture, the pattern you see across summers becomes easy to follow.
Myth two: an old nest attracts new wasps
People sometimes think the old nest carries a scent or acts as a marker. There is no good reason to think so. A queen is looking for a gap with certain features, and the presence of a dead nest is not one of them. If anything, a crumbling shell is a sign that the spot is exposed. That said, a heavy old nest can be in the way. It may occupy the space a new one would use, and its removal changes the look of the place. The main reason to take it down is tidiness, and the second is that a clear space lets you see a fresh start more easily.
A related idea is that you should leave the old nest in place as a decoy, so that queens will be put off. There is no reliable reason to think this works. Neither leaving it nor removing it will make a meaningful difference, so take it down or leave it according to what suits you and how safely you can reach it.
Myth three: taking down the nest solves everything
Taking down a finished nest does not alter whether the gap behind it is open. If you want to reduce the chance of a repeat, the focus should be on the opening, such as the hole in the eaves, the crack in the wall or the burrow in the bank. You can remove the shell and still have exactly the same invitation for the next queen. In Harlington, as in any village or town, the sensible plan is to remove the shell if it bothers you, repair the gap in winter and check the spot weekly from April.
Do the repair at the right time. The best moment is mid-winter, when nothing is flying and there is little chance of trapping a live wasp. If you take the nest down and fix the gap in the same weekend, you will have used the time properly, and you will only need to look again in April to see if anything has changed.
Myth four: wasps are only a problem when you disturb them
Wasps defend a nest, and anything that vibrates or blocks it can cause a reaction. But the more common situation is that a nest sits close to a door, a washing line or a play area, so people are disturbed simply by going about their day. A nest does not need to be provoked to cause trouble, and the size of the colony in August means the risk is higher than it was in June. This is the reason to act earlier in the season. A small nest in May is less of a problem than a nest of up to 2,000 wasps in August.
Wasps in late summer are also drawn to sweet food and drinks, and they can be a nuisance at barbecues and outdoor tables even when the nest is some way off. Covering food and drink, keeping bins closed and clearing up quickly all help, but they do not replace dealing with a nest that sits close to where people spend time.
Myth five: you can deal with it yourself
Sprays, smoke, boiling water and blocking holes all feature in garden advice, and all are risky. A nest that is disturbed but not destroyed can send wasps in every direction, and if the nest is in a wall, they can come into the house. The safest approach is to leave it, keep people away and ask a qualified technician to treat it. Do not climb ladders, and do not approach a nest in the evening thinking they will be calm. Wasps still guard a nest at dusk.
Medical help is rarely needed after a single sting, but be ready. Wash the area, remove the sting if you can see it, and use a cold pack. If there are signs of a serious allergic reaction, such as swelling of the face, lips or throat, wheezing, difficulty breathing, dizziness or a widespread rash, call 999. Anyone with a known allergy should speak to their GP.
