Do Wasps Return to the Same Nest Every Year? A Guide for Sturry Gardens
Garden buildings are used a few weeks a year and left alone for the rest, which makes them ideal for a wasp colony to establish itself unnoticed.
A building that sits empty most of the year
Summerhouses, log cabins, playhouses and garden offices have an odd rhythm. They are busy on warm weekends and unused for months at a time. In between, they are dry, still and mostly dark.
To a wasp queen, that looks like a purpose-built nest site. Timber cladding has gaps, roof felt has curled edges, and the floor is raised on bearers with a hollow beneath. Inside, there are cushions, boxes and games, which provide more cover.
If you found an old nest in a garden building last autumn, it was built for one season. The wasps have gone, and the nest will not be reused. But the building will still be there, offering the same conditions.
Garden offices that are heated through the winter are less likely to attract queens looking for a cold, quiet place, but the outer shell, the roof edges and the underfloor void are just as exposed as those of a summerhouse.
Many of these buildings are bought as kits and assembled in a weekend, so the gaps are often left as the manufacturer made them, not as a fitter would have finished them.
Common entry points
Wooden garden buildings move with the seasons, and small gaps open at the joints.
- Gaps between roof boards and the wall plate
- Curled or lifted roofing felt at the eaves
- The space under the floor, between the bearers
- Knots and splits in cladding boards
- The seal around windows and doors
- Gaps where the building meets a veranda or deck
Wasps do not need much space, and they will squeeze through anything that gives them access to a dark cavity.
Metal sheds and plastic storage buildings have their own weak points, such as the joints between panels, the base rails and the door seals. Whatever the material, the principle is the same: any gap that leads into a dark void is a possible nest site.
A garden room fitted with a green roof or a layer of shingles has even more places for a queen to explore, with the edges of each layer forming a series of pockets.
An end-of-season routine
When you finish using the building for the year, tidy it with wasps in mind.
- Remove cushions, blankets and cardboard, or store them in sealed boxes.
- Take out any old nest, wearing gloves.
- Sweep out the corners and floor.
- Check the roof edge, door seal and floor for daylight.
- Fix any lifted felt and fit a skirt or mesh under the floor.
- Close all windows and make sure the door shuts tightly.
The less there is for a queen to settle in, the less likely a nest is.
If you store garden furniture in the building over winter, brush it down and check the underside of cushions and parasols, as these are favourite hiding places for a sleeping queen.
Keep paths and the surrounding grass trimmed too, so that the base of the building is visible and easy to inspect.
Play areas and children
A playhouse is likely to be used without much thought by children, who will crawl into any gap. Check it before the first use in spring, and show children the basics: do not put hands into holes, do not go into the playhouse if there is a buzzing sound, and tell an adult at once if you see wasps.
Let children help with the winter tidy, as it gives them a sense of what is safe. Treat a nest as something to be reported, not investigated. If a child is stung, wash the area, remove the sting if visible and use a cold pack. Call 999 if there is swelling of the face, lips or throat, wheezing, dizziness or a widespread rash.
For a log cabin, take a look at the logs themselves. Timber shrinks as it dries, and gaps open between the logs, particularly at the corners. They can be sealed with the appropriate material in winter.
Teach children to treat the building like any other place where insects live: look first, and do not reach into dark corners.
Checking through the season
From late April, look at the building from a few metres away on a warm day. Notice if wasps are entering or leaving a particular spot. A nest in a roof or wall is not going to disappear by itself, and a small one is best dealt with early.
Do not go inside if you suspect a nest. The wasps will be nearby and you will have little room to move.
A nest in a building you use as a play space or an office deserves quicker attention than one at the end of the garden.
It is also worth asking visitors, such as a grandparent or a childminder, to follow the same rule so that nobody walks into the building unaware.
Arranging treatment
If there is a nest in a garden building in Sturry, we can treat it for a fixed £120 per nest, with another nest on the same property at £60 extra and no call-out charge. Each technician we send is fully insured and qualified, and each job comes with one visit guaranteed.
Bookings are taken on 01622 410 019 or complete the form on the contact page at /contact-us/. We open seven days a week, with same-day service, plus evening and weekend slots. Please tell us at booking if anyone in the household is allergic to stings.
Tell us what the building is made of and how high the nest is, if you can see it, as it helps the technician plan.
A short note of any access issues, such as a locked door or a steep path, helps us arrive prepared.
