Can You Remove a Wasp Nest Yourself? Advice for Ashley Homeowners
Soffits, fascias and barge boards run along every roofline, and a loose board or small gap is all it takes for a nest to be built behind them.
A roofline with hidden spaces
The soffit is the board under the roof overhang. The fascia is the board at the end of the rafters, where the gutter fixes. Behind and between them are small spaces that are dry, dark and rarely checked. Gaps, loose boards, cracks or old vents create entrances. Wasps start their nests from late April, depending on the weather, and a colony in such a space can grow to between 2,000 and 10,000 or more wasps by August.
Ashley homes, like any with an overhang, can have this. You may see wasps flying in and out of a gap near the gutter or the corner of the house. You may not see a nest at all, only a steady line of traffic against the sky.
The question of removing it yourself is easily answered. The nest is above head height, behind a board, with an entrance that may be a few millimetres wide. It needs a ladder and a view you cannot get. It is a poor DIY target.
A rainy-day approach may help: sit down with a cup of tea and sketch the house, the roofline and the gap on paper, and mark the number of wasps you see going in during a minute. That is more useful than it sounds.
Why pulling the board off is a bad idea
A tempting thought is to take the board off and see. This opens the nest from the side, directly into the colony. Do not do this. Prising off a soffit or fascia, even a single panel, exposes a nest and sends wasps out at close range, while you are on a ladder.
Similarly, filling the entry gap with sealant or foam can push wasps through the structure into the loft, a bedroom or around a light fitting.
Poking a stick, wire or screwdriver in is no better. The nest may be inches inside.
Also avoid hosing the roofline or the gutter. Water does not deal with the nest, and it can run behind the boards and damage the timber and insulation.
Leave the roofline completely alone until a technician has dealt with the nest.
Older houses may have decorative boards, extra layers of timber or old vents, which provide more hidden spaces. Newer ones may have plastic boards with small gaps at the joins. Both can hold a nest.
Clues from the ground
You can learn a lot without climbing.
- Look for a single spot where wasps keep entering, often a corner, a join between boards or a gap near a vent.
- Look for staining or discolouration on the board, which can show where wasps pass.
- Notice papery grey fragments in the gutter or on the ground beneath.
- Listen from inside, near the ceiling at the edge of the room, for buzzing or scratching.
- Check whether wasps appear at the windows of an upstairs room on that side of the house.
If you can, stand across the road or at the far side of the garden and watch the roofline through binoculars. That gives a view of the entrance without getting under it.
Gutter clearing is another trap. The ladder rests against the very board where wasps may be entering, and vibration from scooping out debris can alert the colony. If wasps are about, put the job off until the nest has been dealt with.
Think about how the roofline looks from the road as well. A neighbour or passer-by may have a better view of the nest entrance than you do, and a quick chat can add to your notes.
Safe habits while you wait
Treat the ground below the nest as out of bounds. Move chairs, toys and washing lines away. Use another door if possible. Keep windows on that side closed.
If wasps enter the house, keep calm, close the door of the room and open a window elsewhere. Do not swat.
If anyone is stung, wash the area, remove a visible sting and use a cold pack. Get emergency help on 999 if there is dizziness, a widespread rash, swelling of the face, lips or throat or wheezing or difficulty breathing. A person with a known allergy should speak to a GP, and the booking team should be told so the visit can be prioritised.
Check your gutter and roofline from a distance again in a day or two to see if the traffic is rising.
Keep pets and children away from the area under the roofline too, since debris and disturbed wasps can drop straight down from above. Even a quiet board can release insects when a door slams below it.
Booking a roofline nest
A technician with the right access can treat a nest behind the roofline. Wasp Exterminator Kent treats a nest for a set £120 per nest and one visit is guaranteed. Should you have another nest, it is £60 for that one. No call-out charge is made, and the price is the same for any location or time of day. Technicians are fully insured and qualified.
Domestic and commercial properties are covered every day of the week, with same-day service, evening and weekend slots. Contact the business on 01622 410 019, or through the booking form on its contact page.
Tell the team which side of the house the wasps use, and ask whether the empty nest can be taken down and whether any board needs attention afterwards.
Afterwards, ask the technician about any repair to the boards or the gap, and who should do it. A tradesperson can fix a loose board once the nest has been treated, and it makes sense to do it before next spring.
