Wasp Nest in Your Garden Shed? Safe Treatment Options in Potters Bar
Garages have their own nesting spots, from door tracks to roof joints. This guide covers the clues, how to use the garage safely, and how treatment is arranged.
Why garages attract wasps
A garage is not only a larger shed. It has a roof void, an up-and-over or roller door, side windows, vents and sometimes a flat roof. It is also often left shut for long periods, which suits a queen looking for dark, dry quiet. In Potters Bar, as in any town, a garage can have a nest long before anyone notices.
The difference with a garage is that you use it. You park the car, collect the bins and bring in shopping, so there is a real chance that you will walk into the flight path.
Another feature of garages is that they are often left shut for weeks in cooler months. A queen that gets in then has a head start, and the first sign may not appear until the colony is established.
The places to check
Look from the outside first, from a distance of a few metres.
- the top of the door, where the track or the housing leaves a gap
- the join between the door and the frame
- the roof edge, fascia and any gap under the roof sheeting
- vents and cable entries
- the side of the building where it meets a neighbouring wall
Inside, if you must go in for the car, look up at the ceiling and the upper corners before you switch on the light.
Up-and-over doors have a hollow frame, and the gap along the top between the door and the lintel can be a surprising entrance. Roller doors have a box at the top that is dark and dry. Both are easy to overlook when you are in a hurry.
If your garage has windows, check them from outside. A nest sometimes starts in the gap behind a blind or curtain, and you can sometimes see wasps against the glass, trying to get out.
Using the garage safely while you wait
If you think there is a nest, avoid using the garage door more than necessary. Opening and closing it creates vibration, and some doors are noisy. If you have to retrieve the car, do it calmly and quickly, without slamming doors. Do not leave a car door open near the entrance.
Keep children and pets away from the area. Park elsewhere, if possible, until the nest has been treated.
Never spray or hose the door frame, block the gap or knock the door in an attempt to dislodge wasps. All of these tend to make the wasps more defensive.
If you share a driveway with neighbours, tell them what you have found and keep them away from the garage door. A friendly warning prevents an accidental sting and shows you are dealing with it.
Teach everyone in the household which door to use for the car and which to avoid. If the garage has a side door, that may be further from the nest than the main door, and using it only briefly is better than opening the large door repeatedly.
Roof voids and shared walls
Some garages have a loft space or storage platform. A nest can sit in the space above the rafters, and wasps leave through a gap you cannot see from below. In a terrace of garages or a block of lock-ups, the nest could be in a shared structure.
Tell the technician if the garage is attached to another building or shares a wall. If it belongs to a landlord or a management company, check your agreement for who is responsible for pest problems rather than assuming.
Make note of cables and pipes. A flat roof may hold a nest in the felt layer, with the entrance on the edge. If your garage has a lean-to extension, check that too.
Be careful with the garage if it is attached to the house. A nest in the roof void may be connected with the loft, and wasps can enter the house through a door, a gap or a vent. Close any connecting doors and keep them shut.
Booking and what to expect
For a garage the arrangement is the same as for any building. One nest costs £70 and an extra nest on the same property is £30, with nothing charged for the call-out. You are told the figure on the phone before anyone comes, and a high roof edge or other awkward spot that needs special access equipment could raise it.
Ring 07852 111 437 or use the online booking form. The technician is fully insured and qualified, works seven days a week and can often offer same-day service, as well as evening and weekend appointments if you would rather be at home when it happens. Mention the car and whether the door is manual or electric.
Mention the type of door you have, how high the roof is and whether the garage is detached. Those details help to work out what is needed.
If the garage is a separate block, tell the owner of the neighbouring garage, since wasps do not respect a boundary.
Afterwards
Ask the technician when it is safe to use the garage again. When you do, check the corners and the ceiling before moving anything. Seal small gaps around the door frame and vents when the area is clear, and keep the door closed when you are not using it.
If you store items in the garage, keep them in lidded boxes and keep a clear gap from the walls. Ask the technician at booking whether the empty nest can be taken down.
When the nest is gone, clean the floor, remove cobwebs and clutter from the upper corners and replace any broken roof sheeting, which gives wasps a path in.
