Wasp Nest in Your Garden Shed? Safe Treatment Options in Yeadon
The classic mistake with a ground nest by a shed is mowing, strimming or digging near it. Here is how to recognise the signs and arrange treatment instead.
The mistake: cutting the grass around the shed
The most common way people discover a ground nest is the hard way. They set off to strim the long grass along the back of the shed, and within seconds a cloud of wasps is up around them. The noise and vibration of a mower or strimmer are among the worst things you can bring near a nest in the earth.
This catches out many householders because a ground nest does not look like a nest at all. There is no grey papery ball to warn you. The colony lives in a cavity underground, often an old rodent burrow, and the only visible sign may be a hole in the soil about the size of a ten pence piece or a little larger.
If you are reading this in Yeadon with a shed at the bottom of the garden and a lot of wasp traffic near its base, switch off the machinery and read on. The checklist below will help you decide what to do next.
Checklist: signs of a nest in the ground
- Wasps flying in and out of a single spot in the soil, a bank, a compost heap or under the edge of a slab, always at the same point.
- A small mound of loose earth by the hole, or soil that looks recently disturbed.
- A trail of wasps coming and going in a straight line at about knee or ankle height, rather than hovering around flowers.
- Wasps appearing to emerge from a gap at the foot of the shed wall, where the base meets the soil or a concrete plinth.
- A noticeable increase in wasps around the lawn, even though there is little in bloom.
Because the nest is hidden, it is easy to underestimate how many wasps are in it. A colony that began in late April can be large by August, and a ground nest can hold thousands of wasps just like a nest in a roof. The fact that you cannot see it does not mean it is small.
One more thing worth knowing is that a ground nest does not stay the same size of hole. As the colony grows, the workers enlarge the entrance and the loose soil around it spreads, so a hole that looked like a mouse burrow in June may look much bigger by late summer. If you have seen the hole widen, that is a further sign the nest is established.
What not to do near a ground nest
After the strimmer, the next set of mistakes involves liquid. People pour boiling water, petrol or washing-up liquid down the hole in the hope that it will end the colony. We would strongly advise against all of these. They are dangerous, they can harm the garden and nearby plants, and they leave you standing right next to an angry nest.
- Do not pour anything into the hole.
- Do not cover the hole with a slab, bucket or soil. Wasps will dig out another way.
- Do not stamp on the ground or poke it with a stick.
- Do not let children or pets use the lawn near the nest. Dogs are especially likely to sniff at a hole and get stung.
- Do not carry on mowing around it. Mark the area with a few canes from a safe distance instead, if you can do that without approaching.
If you or someone in the household is allergic, keep them indoors and tell us when you book.
How treatment works for a shed and ground nest
A ground nest is treated in the same way as any other: by a trained, insured technician who finds the entrance and deals with the nest. You do not need to dig, flood or cover anything beforehand. The price is a fixed £90 per nest, confirmed on the phone before the technician visits, and no work is carried out without your agreement.
When you ring, tell us where the hole is in relation to the shed, whether the lawn is open or fenced and whether there is more than one hole. It is possible for one garden to have a ground nest and a second nest in the shed roof, and the additional nest on the same property is £35.
There is no call-out charge, and we offer same-day service seven days a week. The price graphic on our site shows a one-visit guarantee. You can reach us on 0113 347 0014, or use the online booking form on the contact page.
While you wait, keep the lawn clear. If the technician arrives and cannot see the entrance from the path, a quick description of where you saw the wasps going in is usually enough.
Afterwards: tidying the ground and reducing the risk
Once the technician has treated the nest and told you it is safe, you can start to return the garden to normal. Allow some time before mowing near the spot, and do the first cut with care in case a few wasps are still in the area.
The hole can be filled with soil and firmed down. If the nest was in a bank or beside a slab, a little re-turfing or a layer of gravel afterwards helps discourage another queen from taking over the space. Keeping the grass short around the foot of the shed, and clearing old plant pots, bags and boards that lie on the ground, reduces the number of sheltered spots for next spring.
Look also at the base of the shed. If there is a gap where the floor frame meets the ground, a strip of timber or mesh over it keeps wasps out of that space. Doing the work in autumn or winter, when no wasps are flying, is the safest time.
If a fresh hole appears next season, do not wait. Early nests are quieter and easier to deal with, and a quick phone call is far less trouble than another run-in with the strimmer.
Think also about where you will run the mower in future. Mark any area where you have had a nest with a stone or a small plant pot so that you remember to walk the strimmer round it in spring and check it first.
