Do Wasps Return to the Same Nest Every Year? A Guide for Istead Rise Gardens
Moving into a house in autumn or winter can mean discovering a previous summer’s wasp nest, and a short, calm checklist is all you need to deal with it.
The surprise in the roof or the garden
You get the keys, begin to unpack, and a few weeks later you find a grey paper ball in the shed, behind a bedroom wardrobe in the loft hatch or among the branches of a tree at the bottom of the garden. It is natural to feel a jolt of alarm, and to wonder what else the previous owners did not mention.
In most cases the previous owners did not know about it. Nests are often hidden, and many are only found after the leaves fall or the loft is emptied. A nest found in the colder months is nearly always an abandoned one.
The question that follows, whether wasps return to the same nest, has a clear answer. They do not. The colony is a single-season affair, and the old nest is never reused.
Try to resist the temptation to deal with it straight away. A nest found in the cold months can wait a few days while you think, and nothing about it is urgent. Take a photograph, note where it is, and plan the job for a dry, cold day when you have time.
What the empty nest means for you
The shell tells you a few useful things, and none of them is bad news. It tells you that some part of the property was suitable for a wasp colony last summer. It tells you where to look in spring. And it tells you that the structure has ended, because the colony dies out each autumn and only mated queens survive.
It does not tell you that wasps are coming back to it, and it does not tell you that the property has a continuing problem. Every property has places that a queen might choose, so a nest in your first year is simply information.
New residents in Istead Rise or anywhere else are in a good position, because you can learn the property’s weak points before the season begins.
You may also find that the nest is bigger than you expected. A late-summer colony can build a shell the size of a football or more, and the paper is surprisingly light once it is empty. Size says something about how large the colony became, but nothing about what will happen next year.
A first-winter walk-round
In your first cold months, take an hour to look at the house and garden with wasps in mind.
- Check the loft hatch and, if safe, the roof space for old nests or daylight gaps.
- Look along the eaves, soffits and fascia from the ground.
- Check air bricks, vents and the places where pipes pass through walls.
- Open the shed and garage and look at the roof and corners.
- Look at hedges, trees and shrubs for papery shapes.
- Check the lawn and borders for empty holes.
Write down what you find, with photographs. This list becomes the basis of your spring checks.
Do not forget the less obvious places: the space under the stairs, the airing cupboard, the base of the garage door and any outbuilding that came with the property. These are often the least familiar parts of a new home, and so the least checked.
Asking the right questions
If you still have contact with the previous owners or the agent, it is reasonable to ask if they had wasp trouble, and where. Information about the location of an earlier nest is helpful, even if they cannot say how bad it was.
Be careful with anything legal. If you are renting, what you are responsible for depends on your tenancy agreement, and if you own, it depends on your own paperwork and any insurance policy. Check the documents, or ask the landlord or insurer, rather than assuming.
For the old nest itself, the practical rule is to wait until the weather is cold and then bag it with gloves if it is within reach. If it is hard to reach, leave it and mention it when you book a visit.
If a survey or inspection report mentioned insects, damp or gaps in the roofline, read those pages again with wasps in mind. A flagged gap is just the kind of thing worth fixing before spring, and the builder will already have seen it.
Spring: the first test
When late April arrives, you will be glad of the preparation. Spend a few minutes each week watching the spots on your list. A queen looking around is not a nest, but a wasp that keeps returning to the same hole is.
New nests are easiest to deal with early. A colony in its first weeks has few wasps and a small nest, so booking a visit in May is much simpler than doing so in August. Keep children and pets away from any entrance you find, and never try to block it yourself.
It is a good idea to tell the rest of the household what you are looking for. Children in particular enjoy the task, and a family that knows what a small wasp nest looks like is more likely to spot one early.
Booking help in a new home
A treatment for one nest is a fixed £120 per nest, with an additional nest on the same property at £60 extra. There is no call-out charge, and no extra cost for the time of day or the location. Our technicians are fully insured and qualified, and they work in both homes and commercial premises around Istead Rise.
To book, ring 01622 410 019, or fill in the booking form at /contact-us/. We are open seven days a week and can often attend on the same day, with evening and weekend appointments if you are busy unpacking. If anyone in the new household has a sting allergy, say so at booking.
Moving is hectic, so do not feel you have to deal with everything at once. Pick the three gaps that worry you most, fix those in winter, and use the spring watch to catch anything you missed.
