Wasp Nests Under Roof Tiles – A Common Problem for Llangollen Homes
Soffits and fascias hide the entrance to many roof nests, and a few clues from the ground can show you where wasps are going without any need to touch the woodwork.
What soffits and fascias are, and why wasps like them
The fascia is the board that runs along the edge of the roof, usually carrying the gutter. The soffit is the panel beneath the overhang of the roof, running back towards the wall. Between them, the boards, the joints and the roof structure create dark, dry, sheltered gaps, and a wasp queen sees them as good places to build.
Small openings at the corners and joints are enough. A queen only needs a gap about the size of a pencil to get in, and once inside she can build in the space behind the boards where nobody will see.
This is one reason why the first sign of a problem is often a wasp traffic jam at a patch of woodwork rather than a visible nest.
Older and newer houses alike have soffits and fascias, and the boards can be timber or plastic. Wasps can use gaps around either, particularly where two boards meet or where the boards meet the wall.
A householder who has watched a roof edge for a few minutes will usually be able to point to the exact board the wasps favour.
Clues that the nest is behind the boards
You are looking for signs from the ground, not from a ladder.
- Wasps landing on the soffit or fascia and then disappearing.
- A steady line of wasps along the same stretch of roof edge.
- A dull hum from the woodwork when you stand below.
- Small brown stains or marks where the colony has been.
- Wasps found indoors at upper-floor windows.
One or two of these together is a good reason to act. If you can say which end of the house is affected, so much the better.
It can help to compare the roof edge in the morning with the same view in the afternoon. A hum that builds as the day warms is characteristic of a busy colony.
Take a note of any damp or rotten-looking patches on timber, since wasps sometimes exploit existing weaknesses.
If wasps appear to come and go from more than one spot along the boards, say so. A large colony sometimes uses two or three gaps.
What you must not do
It is tempting to prise a board loose to look, or to poke a stick into the gap. Either is likely to unsettle the colony and release wasps at close range. Plastic and timber boards can be fragile, and removing a board from a ladder is an invitation to a fall.
Please do not spray into the gap or fill it with foam. Spraying agitates the wasps and fails to deal with the colony. Foam traps the wasps behind the board and encourages them to find another route.
For a household in Llangollen, in Denbighshire, as anywhere else, the best course is to keep your distance and call for a technician.
There is also a risk to the building itself if boards are forced. Cracked or split boards let rain in, and a repair can cost far more than the problem you were trying to solve.
Keeping the house comfortable meanwhile
A few easy habits reduce the number of wasps you meet.
- Keep windows closed on the affected side during the day.
- Cover food and drink if you eat outside.
- Keep bins lidded and rinse cans and bottles.
- Avoid hanging washing under the area where the wasps are entering.
- Make sure children play away from the wall.
None of this removes the nest. It makes the wait less trying.
Wash any sting site with water, and apply a cold pack. If someone develops swelling of the face, lips or throat, breathing difficulty, dizziness or a widespread rash, call 999.
It also helps to put the car on the other side of the drive, if you have one, because wasps may settle on warm paintwork.
Treatment and price
The nest is treated by a qualified, fully insured technician, and the work is safe and effective. The price is a fixed £80 per nest, and it applies at roof level as it would on the ground. There is no added cost for location or time of day, and no call-out charge. Another nest at the same address costs £40 flat.
One visit is guaranteed. The business covers homes and commercial buildings, offers same-day service and is open seven days a week with evening and weekend appointments.
The technician will ask where on the building you have seen the activity, and whether the property has any outbuildings or an extension with its own roof edge.
Remember that the business offers evening and weekend appointments, so a problem noticed after work does not have to wait for the following week.
The online booking form is also the right route for emergency requests outside normal hours, and no response time is promised, so give clear details.
Booking and afterwards
Phone 07916 322 280 or use the online booking form. Tell the business which stretch of roof edge the wasps are using and whether anyone in the home is allergic to stings.
After the visit, activity should fade. Dead wasps may fall into the gutter or onto the ground, and these can be swept into a sealed bag.
Once the wasps have stopped coming, a builder or joiner can look at the boards and repair any gap. Whether the empty nest can come down is a fair question for the technician.
The business covers Llangollen and the surrounding villages. When you book, mention any special features of the building, such as a porch or a dormer, that might affect where wasps enter.
Keep the confirmation of your booking and note the date. If you see wasps again a little later, those details help the business understand what is happening.
