Wasp Nest in Your Garden Shed? Safe Treatment Options in Deal
The gap under a raised shed is dry, dark and rarely visited. It is a favourite spot for ground-level nests, and easy to overlook.
The space nobody looks at
Many garden sheds sit on bearers, blocks or a low frame, leaving a gap between the floor and the soil. The gap is often partly hidden by weeds, slabs or stored boards. It is dry, sheltered and almost never inspected.
For a wasp, it is ideal. The soil may have an old burrow or hollow, the floor above provides a roof and the sides offer cover. A nest can grow underneath, entirely out of sight, with wasps entering through a slot at the edge.
The first sign may be a line of wasps coming out of the ground at the corner of the shed, or a hum from beneath the floorboards.
Sheds on concrete bases are different. They have no gap beneath, and a nest there would most likely be in the walls or roof. If your shed has a solid base, look instead at the soil around its edge.
Signs from outside
You can learn a lot by watching the base of the shed from a distance, especially on a warm afternoon.
- Wasps flying low and entering a gap at the base.
- Traffic over a patch of bare earth beside a corner.
- A hum or rasp under the floor when you stand inside the door.
- Wasps appearing in the shed through gaps in the floorboards.
- Small crumbs of soil at the entrance where something has been digging.
If you hear a hum from beneath the floor, step back outside quietly and do not stamp or move heavy items.
Weeds growing up through the gap can hide the entrance, so look carefully at the base on a calm, warm afternoon. Crouching to check is not recommended. A standing look from a few steps away is enough.
Keep children away from the area while you watch, and warn them not to peer under the shed. Curiosity about holes and gaps is natural, but this is one to avoid.
What not to do
Do not lift the shed or move its base to look underneath. You would expose yourself to the nest and disturb it badly. Do not pour anything into the gap or block the opening with stones.
It is also unwise to start working at the shed floor. Drilling, nailing or sweeping can send vibrations through the structure.
Keep pets away, because dogs love to dig and sniff at gaps like this, and a nest under the floor is a hazard for them too.
If the shed is on a slope, the gap beneath may be larger at one end. The nest could be at the deep end, where there is more space and shelter. Pay attention to where the traffic is heaviest.
Pets and wildlife also use the space under sheds. A nest in the same cavity can lead to encounters with dogs or cats, so keep animals away from the base until the area has been treated.
Booking in Deal
Wasp Exterminator Kent covers Deal, on the east Kent coast, and the nearby area. Treatment costs £120 for each nest, with one visit guaranteed and nothing extra for a call-out. A further nest at the same address is charged at £60 extra.
The business is open seven days a week, with same-day service, and evening and weekend appointments are available. The online form is there for emergencies out of hours.
Ring 01622 410 019 or fill in the contact page form. Tell the business that the nest seems to be beneath the shed, which side the traffic is on and whether wasps are also in the shed. Technicians are fully insured and qualified.
If you can, take a photograph from a distance showing the base of the shed and any weeds or stones against it. This helps the technician to understand the layout before arriving.
If you have more than one shed or outbuilding, check each base in the same way and tell the business about any that show activity. A second nest is £60 more.
Closing the gap underneath
Once the nest has been treated and the area is calm, think about how to stop it happening again. The gap under the shed can be closed with a skirt of treated timber or mesh, fixed to the base, leaving no easy way in.
Clear weeds and debris from around the base so that the edge is visible. Check the soil for holes and fill them with firm earth.
Ask the technician whether the empty nest can be dealt with, since a nest beneath a floor may not be reachable without lifting part of the structure.
Wait for the all-clear before trimming vegetation or lifting any slabs. Disturbing the ground too soon can send stragglers into the air.
Remember that the floor of the shed may need its own repair if it has been affected by damp or by the nest itself. Look at the underside of the boards in daylight, from outside, when you are confident that it is safe.
Checking again next spring
Make a habit of looking at the base of the shed each month in spring and summer. A short walk around with your eyes on the ground is enough. Look for traffic, bare patches and holes.
If you find anything, stand back and call early. An early nest is much easier to deal with than a full colony.
Keep the shed tidy inside too. A clear floor lets you hear a hum, and a bare floor lets you see gaps between boards.
Raising the shed slightly on blocks, then fitting a skirt, makes it much easier to inspect beneath it in future. Some owners choose a concrete or slab base for the same reason.
