Do Wasps Return to the Same Nest Every Year? A Guide for Telford Gardens
An empty grey nest found in a shed or loft in winter usually prompts the question of whether the wasps will be back, and the answer is more reassuring than most people expect.
What an empty nest in winter tells you
It is common to find a papery ball in a garden shed, under a roof edge or in a hedge once the leaves have fallen. It feels light, it crumbles a little at the edges, and nothing is moving. That is a nest from last summer, and the colony that built it is gone.
Wasp colonies are an annual affair. The workers die off as autumn arrives, the nest is abandoned, and the structure is not occupied again. You are looking at an empty shell, in much the same way as an old bird’s nest in a hedge.
That does not mean the find is meaningless. It shows that your property had conditions a queen found attractive at some point, such as shelter, dryness or an easy gap, and those conditions may still be there next spring.
Gloves are worth wearing if you pick it up, and a dust mask is sensible in a shed where the paper has been breaking down. The material is much like thin card, but it can be dusty and may hold dead insects and droppings from the summer.
Why the colony does not come back
The reason is the life cycle. In spring a single queen starts a fresh nest on her own and raises the first workers. Through summer the colony grows, and in August it has peaked, with as many as 2,000 wasps in a single nest. When autumn comes the colony dies and the old nest is left behind.
Only the new queens go on to survive the winter in sheltered places, and in spring each one looks for a site of her own. A queen has no use for a crumbling, half-eaten nest, and she builds a new one.
So the idea that the same wasps return to the same nest is a myth. What can happen is that a new queen picks a similar spot, because the same features suit her needs. That is a different thing, and it is why a quick check each spring is worthwhile.
It also explains why a nest cannot be recycled by wasps for a second season. The paper weathers, the cells inside are dirty, and the structure cannot be extended in the way a fresh start can. There is simply no advantage in using the old one.
Should you take the old nest down
You can usually leave an empty, abandoned nest where it is without harm, but there are good reasons to remove it once you are certain it is dead. A visible nest by a front door can prompt questions from visitors, and a nest in a loft can attract unwanted attention from other insects looking for old paper.
Be sure it is truly abandoned. A nest that looks empty in October may still have a few slow wasps in it, and one found in spring is a different matter. If you have any doubt, do not touch it.
- Wait for a cold spell, when wasps are far less active.
- Look for coming and going from the entrance over a few days.
- Wear gloves and handle it gently if you decide to remove it.
- Never remove a nest you can hear or that has any wasps moving on it.
If a technician has treated a nest during the season, you can ask whether the empty nest can be taken down.
Making your plot less attractive in spring
You cannot make a garden wasp-proof, but you can reduce the number of easy spots. Look at the building from outside in March and take note of anything that gives a queen a cosy gap.
- small holes and cracks around eaves, soffits and fascias
- gaps beside window frames and vents
- unused sheds with cracks around the door
- piles of old timber, pots and plastic sheeting
- loose bark, hollows and dense dead growth in hedges
Sealing gaps is a job for a tradesperson if it is high up. Do not seal anything that has wasps moving in or out of it, as trapped wasps find other ways and can end up indoors.
Pay attention to the south and west sides of the building, where walls warm up first on spring days. Queens are inclined to explore those first, so a short look at sunny gaps in March is a sensible start.
What to watch for from April
Wasps start building nests in early April depending on how mild the spring has been. A queen working alone is easy to miss, but she is often seen flying slowly along walls and into gaps, as if searching. A nest at this stage might be the size of a walnut, and it is easiest to deal with then.
Check the places that held a nest last year, but also look elsewhere. Walk round once a fortnight through the spring, and look again before the summer holidays. The sooner you notice a new nest, the sooner it can be dealt with.
Keep a simple notebook or a note on your phone with the dates of your checks and what you saw. After a year or two you have a picture of your own property, showing which corners attract interest and when, and that helps you decide where to look.
Remember too that a mild spring can bring things on early. If March has been warm, start your walk-round sooner rather than waiting for April.
