Wasp Nest in Your Garden Shed? Safe Treatment Options in Kippax
Summerhouses, log cabins and timber-clad garden rooms offer wasps plenty of sheltered cavities, and a nest there is best treated professionally before the room is used again.
The direct answer: shut it up and get it treated before anyone sits inside
A wasp nest in a summerhouse or garden room is a bigger concern than one in a plain storage shed, because people spend time in these buildings. The sensible approach is to close the doors and windows, keep everyone out and arrange a treatment before the room is used again.
Timber-built garden rooms have more places for a nest to hide than most people realise: behind cladding boards, in the roof insulation, under the floor on its bearers and in the hollow of a decked porch. The room can look immaculate inside while the colony is building a few centimetres behind the wall.
Where wasps hide in a timber garden room
Look at the building from the outside first. The lower edges of overlapping boards, the corners where wall meets roof and any area around electrical cable entries all create small gaps. A queen can squeeze into surprisingly narrow spaces in spring and enlarge the cavity from inside.
Under-floor voids are another favourite. If the summerhouse sits on bearers or a raised platform, a gap at the front step may lead to a nest underneath. Roofs can hide nests too, particularly where there is a felt layer on a timber deck and a small hole at the ridge.
- Wasps entering at the top of the wall or the apex of the roof suggest a nest in the roof space.
- Wasps appearing at ground level near the front step suggest an under-floor or ground nest.
- Chewed marks in pale, fresh-looking wood show where wasps have been taking fibre to build their paper.
- A hum or rustle behind the panelling is a strong sign of a nest inside the wall.
Try this check on a dry day. Walk slowly around the building at a distance of a couple of metres and look at the boards at roof height and at knee height. Wasps working at timber leave pale, scraped patches that look like someone has run a coarse brush over the wood.
What to avoid doing in a room you want to use
The temptation with a summerhouse is to keep using it and hope the wasps stay in the walls. That is risky: a colony that grows through summer will eventually find a gap into the interior, and nothing ruins a quiet afternoon like wasps appearing around the window.
Do not drill, screw or nail into the walls to ‘find’ the nest, and do not seal the gap with filler while the colony is active. Trapped wasps can chew through, and the new route may open into the room. Keep soft furnishings away from the walls and, if you can do it safely from the doorway without stepping far in, lift out anything that is sitting directly beneath the activity.
If you rent the property or the building belongs to someone else, whether you or they arrange pest control depends on the tenancy agreement, so check it before booking.
If the summerhouse has glazing, look at the windows from inside only if you can do so without disturbing anything and without going further than the doorway. Wasps trapped between glass and curtains are a sign they have already found a way into the room and are looking for the exit.
Safe treatment options
There are two realistic options. You can leave the colony alone and avoid the building until winter, losing a good part of the season; or you can book a technician to treat the nest directly. Because timber is easy to damage, it is useful that the work is carried out by someone trained, rather than a householder improvising with a crowbar.
Our technicians are trained and fully insured. They will look at the structure, find the likely nest position and treat it. If you want the empty nest removed from the cavity, ask at the time of booking; whether it can be taken down depends on where it is built, and the technician can advise.
Each nest costs a fixed £90 for a guaranteed single visit, and there is no call-out charge. Should a different nest be found elsewhere on the property, it is £35. Both domestic and commercial customers are covered, so the same applies to a garden room used for a small business.
Keep the room’s contents in mind. Cushions, throws and boxes of games make comfortable places for a stray wasp to land and be crushed or pinned by accident, which is a common route to a sting. Leave them where they are until the colony has been dealt with, then shake everything out outside.
Keeping a summerhouse unattractive to wasps
When the colony has been dealt with, treat the building to some maintenance. Replace split boards, seal gaps with an exterior filler suited to timber, and check the roof felt for lifted edges. Do this in autumn or winter, when the building is quiet.
During spring, walk round once a week. Early nests are about the size of a golf ball and much easier to deal with than a large one in August.
If you are in Kippax and need to book a visit, phone 0113 347 0014 or use the online form on the contact page. The price is agreed on the phone first. Tell the team if anyone who uses the room has an allergy to wasp stings.
Whether the technician can reach the nest depends on the build of your room, so it helps to describe it on the phone: boards on the walls or logs, a felt roof or tiles, a raised floor or a solid base. Describing the construction plainly is enough.
