Do Wasps Return to the Same Nest Every Year? A Guide for Woodthorpe Gardens
Underground nests leave little behind, so when wasps seem to reappear in the same patch of garden, the explanation lies in the soil rather than the nest.
Nests you never saw
Many wasp colonies live underground, in a chamber dug out from an old rodent burrow or a natural hollow. Unlike a nest hanging from a roof beam, you cannot see it from a window. All you notice is a small hole in a bank, a border or the edge of a lawn, with wasps coming and going.
When the colony ends in autumn, that chamber collapses or is left empty, and the entrance may close over. By the following spring there is no sign. Then, one day in June, wasps appear in the same place and it feels as though they have come back to their nest. They have not. A new queen has found the same convenient hollow, and she has built from scratch.
For anyone in Woodthorpe who has seen this on a sunny bank or in a flower bed, the explanation is a reused hole in the ground, not a reused nest.
What makes a patch of ground appealing
A queen looking for a ground site wants something that is dry, sheltered and already hollow. A previous burrow is ideal because the digging has been done. Banks that face the sun, light and well-drained soil, and edges where grass overhangs all provide the right conditions. Disturbed ground, such as a mound left after building work, can also provide ready-made gaps.
It is worth saying that none of this is a fault of the gardener. A clean, tidy lawn can have a hole just as easily as an overgrown one. The point is simply that burrows persist, so a spot that hosted a nest once is a sensible place to look again.
Spotting a ground nest in season
The give-away is traffic. A steady stream of wasps entering and leaving a small round hole, often about the width of a thumb or a little wider, is a strong sign. You may see them landing briefly on nearby leaves or stones before going in.
- The hole has bare, slightly worn soil around it.
- Wasps fly in a direct line rather than hovering.
- Activity increases through the day and becomes busier as the summer goes on.
The danger with a ground nest is that people step on it or mow over it without realising. The vibration alerts the wasps, and they come out defensively. If you suspect a hole, keep off that area of lawn, and mark it with a stake or cane from a safe distance so everyone in the household knows to avoid it.
What to do with last year’s hole
In winter, if you find an old hole and you are confident it is empty, you can fill it with soil and firm it down. Doing so removes one easy choice for a queen, though she may find a different hollow nearby. Do not attempt this in spring or summer when a nest might be active, since sealing a live entrance does not stop the wasps and can make them agitated.
If you simply want to keep an eye on the spot, stand where you can see it from a distance on a mild day in May. A single wasp repeatedly disappearing into the ground is the cue to take action.
Avoid pouring anything down the hole. It is not a reliable method, and the wasps that come out will be angry.
Mowing, strimming and children
Ground nests catch out people who are busy rather than careless. The strimmer goes along a bank edge, the mower goes over a mound, and the first sign is a cloud of angry wasps. If you have ever had a nest in the garden before, treat the lawn and borders with extra thought in May and June.
Walk the area first. Look at the ground in the area you are about to cut, and listen for buzzing. Keep children, who are likely to run across the lawn or dig in beds, informed of any place that is out of bounds, and remember pets, too. Dogs sniffing at a hole are at risk of being stung on the nose.
If anyone is stung, move away calmly and wash the area with soap and water. Remove the sting if it is visible, and use a cold pack to ease the soreness. Anyone with swelling of the face, lips or throat, wheezing or difficulty breathing, dizziness or a widespread rash should call 999. People who know they are allergic should speak to their GP about it.
Booking a treatment for a ground nest
Ground nests are treated at the same fixed price as any other: £95 per nest, with £35 for an additional nest on the same property. We confirm the price on the phone before the technician visits, and nothing is done until you agree. The technician will need to reach the entrance, so a clear route across the lawn or bed helps. If the hole sits at the back of a bank or under a bush, tell us at the time of booking.
We have no call-out charge, we work seven days a week, and same-day service is offered. Call 0115 937 5117 or fill in the booking form on the contact page, and mention any allergy to wasp stings in your household.
Once the nest has been treated, stay away from the area until the technician says it is fine to return. Then you can go back to mowing and weeding as usual. It is sensible to tamp down any loose soil afterwards, to discourage another queen from using the same hollow in the future.
Next spring, glance at the same patch again. If everything is quiet, good. If not, the same process applies, and the earlier you notice, the smaller the colony will be.
