Wasp Nests Under Roof Tiles – A Common Problem for Thurnham Homes
The eaves are where the roof meets the wall, and they offer wasps a sheltered, easy-to-reach entrance. This guide covers how to recognise an eaves nest and what to do.
Where the tiles meet the wall
Look up at the point where your roof overhangs the wall and you will see the eaves. Under the first row of tiles there is often a narrow cavity, partly closed by the fascia and soffit boards below. Small gaps open up between these parts as timber shrinks and the building settles.
To a wasp in spring, a gap like that is a doorway to a dry, enclosed cavity. Once inside, the wasp builds a small nest and raises the first workers on its own. The colony expands from there and tends to be at its biggest in August.
An eaves nest is the closest to the ground of the roof-level nests, which makes it the most likely to bother you. That is also why it is often reported first.
Houses with climbing plants or old guttering can hide the gap altogether, so a nest at the eaves may be noticed only through the wasp traffic.
Signs that the eaves are in use
Eaves nests announce themselves in a few ways. You do not need to touch anything to spot them.
- Wasps hovering at the base of the roof edge and slipping into a narrow gap.
- A faint papery rustling when you stand quietly below, on a still day.
- Wasps appearing at an upstairs window in the same part of the house.
- Small flecks of wood fibre on the gutter, window frame or path below.
In Thurnham, as anywhere else, the best view is from across the garden. Resist the urge to move closer to look in; wasps near their entrance are on guard.
Pay attention to how the wasps behave as they approach. Those heading in tend to fly low and slow, often carrying food or fibre, while the ones leaving go up and away. Seeing both directions at one gap is a reliable sign that the nest is right behind it.
Why the eaves are not a safe stepladder job
The eaves look reachable. A stepladder, or the top of a conservatory, seems to put you within arm's length. But the wasps are only a short distance away at that point, and you are in the worst position: off balance, with your face at the entrance and no easy exit.
A nest this size is better dealt with by someone who treats nests every working day. The technician has the right protective gear, uses proper access equipment and knows how to approach without alerting the colony. That is the reason to book, rather than to improvise a ladder.
It is also worth remembering that gutters, fascias and soffits are brittle with age. Leaning on them or levering at them can break them and widen the hole.
If anyone in the household is anxious about wasps, make sure they stay indoors during the visit. The technician needs a clear working area, and a calm house means one less thing to worry about.
Resist blocking the entrance
If wasps are streaming in at the eaves, covering the gap feels like the obvious cure. It is not. The colony remains alive behind the board, and workers that cannot get out will find another route. Wasps have been known to chew or squeeze through plasterboard and light fittings.
Instead, keep the nearest windows closed, move garden furniture and play equipment away from the wall, and avoid sitting beneath that stretch of roof. If the wasps are already getting indoors, shut the door of the room and tell the office when you call.
When the nest has been treated, a carpenter or roofer can close the gap with new filler or timber. That is the stage at which blocking it actually works.
There is a further reason not to wait. Every week that passes in summer adds more wasps, and a gap that handles a few dozen insects in June can be handling many hundreds by August.
The fixed price, booking and afterwards
A nest costs a fixed £120 per nest to treat, and a second nest on the same property is £60 more. There is no call-out charge. The price graphic says one visit is guaranteed, and nothing extra is added for the height of the eaves or an evening visit.
Wasp Exterminator Kent is open seven days a week, with same-day service and evening and weekend appointments. To book, ring 01622 410 019 or fill in the form, which is also the way to ask for emergency service outside office hours.
After the treatment, a few wasps may linger around the old entrance. Ask the technician whether the empty nest can be removed. Then have the eaves checked over the winter, so that the gap is repaired by the time wasps emerge in spring.
A final practical point: the treatment is done from outside wherever possible, and you will usually be asked to keep windows shut and pets inside until the technician says it is fine to go out again. Pass on the same message to neighbours if their side of the roof is close by.
Keeping the garden usable while you wait
If you cannot be treated the same day, you can still use most of your outdoor space with a few small changes. The aim is to keep people away from the wasps' route, not to give up the whole garden.
- Move chairs, tables and washing lines at least a few metres out from the affected wall.
- Cover bins and food waste, because wasps visit them as well as the nest.
- Keep doors to the affected side closed or fitted with a fly screen.
- Tell visitors and delivery drivers if the front door is under the nest.
Mowing near the wall, trimming climbers on the house and using power tools close to the eaves can all shake the building. Postpone those jobs until the nest has been treated.
