Wasp Nest in a Hedge or Bush – What Denaby Garden Owners Should Know
Not every hedge nest is up in the branches. Some are at the foot of the plant, in the soil, and they catch out people who are only looking up.
Looking down instead of up
Most people picture a wasp nest as a grey ball hanging from a branch. In a garden hedge, though, plenty of colonies are underground. A hole beneath the lowest branches, a gap between roots or a patch of bare earth at the foot of a shrub can all lead to a nest in the soil.
This matters because you can walk past, mow or weed beside one without noticing a thing. Gardeners in the Don Valley, from Denaby to the towns around it, usually find these nests when a mower passes or when someone kneels to pull weeds under the hedge.
Another reason ground nests are tricky is that the visible hole is only the entrance. The chambers underneath may spread further than you expect, which is one more reason for leaving the work to somebody trained.
Look at the soil colour as well. Fresh, pale earth around an entrance suggests recent activity, while a hole that is covered in cobwebs or leaf litter and has no traffic is likely empty.
Signs at ground level
A ground nest is easier to confirm than to find by chance. Watch the base of the hedge on a dry, warm day.
- A small, round hole in the soil, often the width of a thumb or two, with wasps passing in and out in a steady stream.
- Loose, crumbled earth around the hole, as if something has been digging.
- Wasps landing, walking into the hole and flying out again along a consistent line.
- Activity that rises through the afternoon as the weather warms.
A single wasp wandering across the lawn is not a nest. A regular traffic of wasps into one hole is.
Do not rely on a single glance. Ground nests often show most activity once the day has warmed, and an entrance that looked quiet at breakfast can be busy by mid-afternoon.
Why the base of a hedge appeals to wasps
The foot of a hedge is sheltered, shaded and rarely disturbed. Dry soil, an old burrow left by another animal or a gap under thick growth gives a queen a ready-made space to start in the spring. Nests begin in early April in a mild year, and the colony grows through the summer to a peak in August.
Because the nest is below ground, it can expand quietly beneath you. By mid to late summer the traffic at the entrance can be considerable, and anything that shakes the soil, like a mower or a heavy boot, may trigger a defensive response.
The warmth of the sun on a south-facing bank or a dry border makes it especially attractive. Do not assume that a damp or heavily shaded spot is safe either, as wasps vary in what they accept.
Dry banks and the soil beneath a hedge are particularly attractive when they sit against a wall or fence, as these hold the day’s warmth well. Check such spots first when you walk the garden.
What you should not do
Resist the temptation to deal with it yourself. Pouring liquids into the hole, covering it or stamping on the ground does not make the colony go away, and it can send angry wasps in your direction.
- Keep the lawn mower and strimmer well away from the area.
- Mark the spot from a distance, for example with a bright cane pushed in a couple of metres back, so family members know to avoid it.
- Keep children and dogs off that part of the garden.
- Do not fill the hole in. Blocking an entrance can drive wasps to find another route, sometimes into the house.
Stay calm and give the area a wide berth. That is the best thing you can do until a technician has been.
If your dog or cat likes to dig under the hedge, bring them in. Pets are often stung on the nose and paws when they investigate a hole, and it is not something they will learn to avoid.
Preventing a repeat in the spring
You cannot guarantee that no wasp will ever nest in your garden again, but you can make the hedge base less inviting and spot trouble early.
- Keep the ground beneath the hedge tidy, so that gaps and holes are visible.
- Walk the base of the hedge now and then in April and May, looking for small holes and wasp activity.
- Fill in obvious disused burrows once you are sure nothing is using them.
- Keep an eye on the same area when the weather warms, as queens look for sheltered, dry spots.
Catching a nest in its early weeks is much easier than dealing with a large colony in August, and it means fewer wasps in the garden over the summer.
It can also be useful to tell the technician where the hole is in relation to the house, a path or a fence. A quick description over the phone, such as the third shrub from the gate, saves time on arrival, particularly if the hedge is overgrown and the hole is hidden by foliage.
Treatment and getting the garden back
A ground nest is treated by a trained technician who is fully insured and qualified. The price for one nest is a fixed £70 per nest, with £25 for another on the same property, and you are told the price on the phone before the visit. There is no call-out charge. If the hedge base is hard to reach and special access equipment is needed, the price may be higher, which will be agreed first.
You can call 07798 792 774 or use the contact page. The business is open seven days a week and can often attend the same day.
Wasps may still fly around the entrance for a while after the visit. Keep clear until the technician says it is fine. Afterwards, tidy the hedge base and check the area is quiet before you mow or weed again.
