Wasp Nest in Your Garden Shed? Safe Treatment Options in Mabgate
A small hole in the soil beside the shed, with wasps dropping in and out of it, points to a nest underground rather than in the building itself.
A hole in the ground and a steady stream of wasps
You are carrying a watering can past the shed when you notice wasps moving low over the grass, then vanishing into a small hole beside the concrete base. A minute later another one emerges. Nothing is attached to the shed wall and the roof looks quiet, yet the activity is plain.
This is the typical picture of a ground nest. Wasps will use old rodent burrows, gaps beneath paving, the space under a shed floor or the soil bank behind it. The entrance is often only a couple of centimetres across, easy to miss until you see the traffic.
How a ground nest differs from one in the shed
The behaviour gives it away. A nest in the building produces traffic at roof height or at a crack in the wall. A ground nest produces traffic at knee height or lower, and the wasps tend to approach and leave in a low, straight line.
- The entrance is a hole, a crack in the soil or a gap beside a slab, and may have loose crumbs of earth around it.
- Wasps appear to land on the ground and walk in rather than flying through a gap.
- Traffic increases through the morning and stays busy on warm afternoons.
- The shed floor may be raised on bearers, so the nest could sit under the boards without a visible hole inside.
A nest under the floor is awkward, because the colony is only a few inches from where you walk. If you hear a buzz through the boards, treat the shed as unsafe to enter.
The mower problem
Ground nests have a bad reputation because people find them by accident. A mower, strimmer or spade passing close to the entrance sends vibration through the soil, and the guards respond at once. Stings from a ground nest often come in numbers, because many wasps can emerge together.
If you have noticed a hole, mark the spot from a distance with something light, such as a bamboo cane pushed in a safe distance away, and keep strimming or cutting away from the area. Stay off that stretch of lawn until the nest has been dealt with.
A ground nest changes how the whole garden can be used. Dogs are curious about holes and will sniff at an entrance, which is exactly the wrong thing to do. Young children playing near the shed may not notice the traffic at all. Until the nest is dealt with, treat the area around the shed as out of bounds.
If your washing line, compost bin or water butt is next to the shed, think about whether you can leave those jobs for a few days. Short, unhurried visits at a distance from the hole are far safer than a quick dash that ends with a sting.
What to avoid doing
Pouring boiling water or petrol down a hole is a common idea and a bad one. It can anger the colony, damage the ground and put you at risk. Covering the entrance with a slab or a bucket is equally unwise, because wasps dig or find another way out, perhaps through the shed floor or the wall.
- Do not block or fill the hole.
- Do not dig around it to take a look.
- Do not leave the lawn mower running near it.
- Do not let dogs sniff around the base of the shed.
Keep an eye on the children’s play areas too. A ground nest close to a trampoline or a sandpit is a good reason to book promptly.
Having it treated in Mabgate
We treat wasp nests, including ground nests, at a fixed price of £90 per nest. If you find a second nest on the same property, that one is £35. There is no call-out charge and the price is confirmed on the phone before anyone comes out. Nothing starts until you agree to go ahead.
Our technicians are trained and fully insured, we work seven days a week and offer same-day service, and we look after homes and commercial premises. Ring 0113 347 0014 or fill in the online form on the contact page. Please say if anyone in the household is allergic to wasp stings so that we can take this into account.
At the visit the technician will locate the entrance and treat the nest. You can ask when you book whether anything can be done about the empty nest.
Once the colony has gone, you can fill the hole with soil and firm it down. Keep the base of the shed tidy, trimming grass and weeds back from the edges so that gaps are visible. If there are gaps beneath the shed floor, a fine mesh across them will stop animals moving in and making the burrows that wasps like to borrow.
Throughout the season, look at the ground by the shed once a week. Early signs are easiest to deal with, and a single wasp entering a hole in May is a far gentler problem than a busy entrance in August.
Looking back at the season
Nests begin in late April, depending on how mild the spring has been, and grow through the summer until August. That means a hole that was unnoticeable in June can be the centre of intense activity by late summer. If you suspect something, do not wait to be sure; a short phone call can settle it.
If you cannot tell whether the insects are wasps, describe their behaviour to us. Slim, smooth, yellow and black insects entering a hole in the ground are very likely wasps.
When the weather is cool and wet, activity at the entrance drops, and it is easy to believe the colony has gone. Do not rely on that. A quiet day is not proof, and a warm spell soon brings the traffic back. If you have seen the hole once, assume it is still in use until the nest has been treated.
