Do Wasps Return to the Same Nest Every Year? A Guide for Bilborough Gardens
Last summer's nest will not be lived in again, yet a fresh colony can start close by in spring, so it pays to know what to look for.
The short answer: no, but the spot can be tempting
A wasp nest is built for one season only. When autumn arrives the colony winds down, the workers die off, and the paper structure is left empty. The following spring a different wasp, a queen that survived the winter on her own, begins a brand new nest from scratch. She does not move into the old one.
That is the good news for anyone in Bilborough who spent last summer worried about a nest under the eaves or in the garden. The bad news is that the idea of “never again” is not quite true either. A queen looking for somewhere to build is drawn to the same sort of space that suited the last one: dry, sheltered, quiet, and reached through a small gap. If last year's spot is still available, it can look just as good to her.
So the sensible way to think about it is not “will they come back to that nest” but “is that place still an inviting one”. Everything below is about answering that second question.
What actually happens to an old nest
Once the colony has died, the nest has no occupants and no function. Leftover cells may hold a few dead insects, and the outer paper layers become brittle and fall apart over winter. Rain and frost speed that along, particularly if the nest was in a hedge, a tree or a hole in the ground.
Nests inside lofts, wall cavities and sheds can stay in one piece for much longer because nothing disturbs them. Householders sometimes find one months later and assume it must be a new problem. It is almost always just the remains of the previous season.
A few points are worth keeping in mind:
- An empty nest does not make wasps return to it, and it does not give off any signal that draws them back.
- A very old, intact nest can still catch your eye and get mistaken for an active one, so look before you assume.
- If you are not certain the nest is dead, do not poke it. Wait until the weather has been cold for some time, or ask us.
Why a new queen might choose the same corner
Queens emerge from hibernation when the weather turns mild, which can be from late April depending on how the spring goes. Each one is searching alone for a sheltered cavity. She is not remembering anything; she is simply choosing the spots that meet her needs.
The features that tend to appeal are easy to describe. A narrow opening that leads to a larger hollow space. Protection from rain. Not too much disturbance. Soft or crumbly material nearby that she can chew for paper. Because a house or garden repeats the same features year after year, new nests do sometimes appear close to old ones.
This is why we suggest treating the earlier nest site as a place to keep an eye on rather than a place that has been “dealt with”. The aim is to catch a new nest while it is small, before the colony has grown through the summer towards its August peak.
Why people think the same nest is back
The belief is understandable. Householders see a nest in the same corner of the loft or the same bush two summers in a row and conclude that the colony has returned. What has usually happened is that the first nest has quietly broken down and a new, much smaller one has been started nearby by a different queen.
There is another reason the idea sticks. A nest in a hidden place such as a cavity wall leaves no visible trace once it is finished, so the first you know of the replacement is the buzzing of the next colony in June. It feels like a return, but it is a fresh start.
Tidying up an old nest safely
If the nest is plainly old and sits somewhere easy to reach, such as a branch in a shrub after leaf fall, you can usually remove it without drama. Do this in cold weather, wear gloves, and put it in a bag for the bin. Do not shake it indoors.
If it is high up, behind a fascia, in a chimney or inside a wall, leave it where it is unless it is causing a nuisance. Wasps are not going to reuse it, and trying to dig it out can cause more mess than it solves. Should you want it removed, ask the technician at booking whether the empty nest can be taken down.
Whatever you do, avoid the temptation to block an entry hole straight away. If there is any chance the nest is still occupied, sealing it in can push wasps into the house through other gaps. Confirm it is empty first.
What to check next spring
The simplest routine is a short walk around the property every week or two from late April, looking at the places wasps have used before and the places they like generally. You are looking for a few insects going in and out of one point, repeatedly, on a straight line.
- Eaves, soffits and the tops of walls.
- Airbricks, vents and small cracks in render or pointing.
- Sheds, garages and the underside of any roof overhang.
- Bare patches or small holes in lawn, banks and flower beds.
- Dense hedges and the base of shrubs.
