Wasp Nest in a Hedge or Bush – What Lincoln Green Garden Owners Should Know
Some of the most startling nests sit not in the branches but in a hole at the foot of the hedge, and the mower is usually what finds them.
The mower stops mid-row
You are halfway along the edge of the lawn, running the mower close to the hedge line, when wasps lift off the ground ahead of you in a cloud. You let go of the handle, back away and wonder where they have come from. There is no nest in the branches above, and nothing visible in the hedge at all.
What you have probably disturbed is a nest below ground level, in a hole at the base of the hedge. Wasps will happily take over an old burrow or a gap between roots, and the soil, roots and leaf litter above them make a very effective lid. The only clue is a small opening, often no wider than a coin or a thumb, with a regular movement in and out.
Householders in Lincoln Green and elsewhere meet this most often in the second half of summer, when the colony is large and a mower or strimmer passing close by makes a great deal of noise.
Telling a ground nest from other holes
Gardens have all sorts of holes. Worm casts, mouse runs and the tunnels of solitary bees can all appear under hedges. A wasp nest entrance has some distinct features.
- Wasps travel in and out all day in a steady, purposeful way, not in the odd one or two.
- The entrance is a clean round hole with the soil around it a little worn or bare.
- Wasps often land briefly on nearby leaves or soil before dropping into the hole.
- If you stand still at a safe distance you may hear a low humming from the ground.
Never lean over to check. If you can see wasps entering from three or four metres away, that is close enough. Do not pour anything down the hole, and do not stuff it with soil or stones, since blocked wasps tend to dig a new route or go for the nearest moving target.
Dealing with the garden in the meantime
The aim is to stop anyone going near the base of that hedge until the nest has been treated. Cut the mowing short and finish the other parts of the lawn, but leave the stretch beside the hedge alone. Put a visible marker well back from the entrance, such as a stick with a bright rag on it, planted by someone who stays at a safe distance. If you have a garden gate, tell any family members and callers.
Do not use a strimmer or blower near that side of the hedge. Strimmers are loud and vibrate the ground, and a ground nest responds to this immediately. Keep dogs on the other side of the garden and children indoors if the lawn is close to the nest.
If you do get stung, move away calmly, wash the sting site, take the sting out if you can see it and use a cold pack. Call 999 if anyone shows swelling of the face, lips or throat, difficulty breathing, dizziness or a spreading rash.
How deep and how big a ground nest can be
People are often surprised that a nest below ground can be as large as one in a roof space. The wasps dig out and enlarge a chamber in the soil as the colony grows, so what starts as a small cavity in spring may be a good deal bigger by the summer peak. The same numbers apply as anywhere else: from 2,000 to 10,000 or more wasps in August.
That matters for safety, because the entrance is only the visible part. The wasps are spread through the chamber, and when the ground shakes, the ones near the surface rush out first while the rest follow. Never think of a small hole as a small problem.
It is also why the area beside the hole needs to stay free of people. Walking heavily across the soil above the nest, even without noticing it, can cause the same reaction as the mower.
What a visit costs and how to arrange it
A ground nest at the base of a hedge is treated the same way as any other, at a fixed £90 per nest. If there is a second nest on the property, it is £35. No call-out charge applies, and the price is confirmed on the phone before the technician visits. You decide whether to go ahead.
Wasp Exterminator Leeds is open seven days a week, offers same-day service, and works with trained, fully insured technicians for both domestic and commercial customers. To book, call 0113 347 0014 or use the form on the contact page at /contact-us/. If someone in your home is allergic to stings, mention it then so that we can take it into account.
It helps to describe exactly where the hole is, for example how many steps along the hedge from the gate, and whether the ground is level or sloping.
Mowing and edging again
After the treatment, let the technician tell you when it is fine to go back. Returning wasps may visit the old entrance for a short time, and it is better to stay clear until that stops.
Once the all-clear comes, the old hole can be filled in. You may find the nest chamber left as a hollow in the soil, and it is sensible to ask the technician about any remaining nest material before you dig.
Looking forward, make a habit of walking the hedge line before you mow, once a fortnight from May. You are looking for wasps entering the soil near the roots. Wasps begin building from late April depending on the spring, and finding a small ground nest in June is far easier than finding a big one in August.
