Wasp Nests Under Roof Tiles – A Common Problem for East Sutton Homes
The fascia board runs along the edge of the roof, and the gap behind it is a favourite wasp entrance. Here is how to recognise a nest hiding there.
The board along the roof edge
Look at the edge of your roof where the gutter is fixed. The long board behind the gutter is the fascia. It closes off the end of the rafters and gives the gutter something to hang from. Where it meets the first row of tiles, or where one length of board meets another, there are often narrow gaps that open as timber ages and shrinks.
A wasp searching for a nest site in late April or May finds a gap like that attractive, because behind it lies a dry, dark cavity that runs along the roof edge. The first cells are built there, and by the height of summer a colony of thousands may be using that same slot.
A nest behind a fascia can be a long way from the entrance that you see. The wasps may slip into the gap at one end of the board and build some distance along.
The result is that in East Sutton and everywhere else, an unsuspecting householder sees only a thin line of wasps vanishing behind the guttering.
What gives it away
Because the gutter partly hides the gap, it can take a while to spot. The signs are small but consistent, and most can be seen from the ground with a little patience.
- Wasps appearing from behind the gutter, at a joint in the board or a corner.
- A faint brown mark running down the face of the fascia below the entry.
- Fine wood shavings or grey flecks collecting in the gutter or on the ground below.
- A dry, papery rustle when you stand very still beneath the roof edge on a warm day.
- Wasps at an upstairs window directly above the gap.
None of these needs a closer look than the garden path. Use binoculars or a zoomed phone photograph, and stay out of the line between the gap and the open sky.
It can help to look at the gutter itself. Wasps often leave tiny dark marks where they have crawled over the edge, and in older plastic gutters you can sometimes see a gap between the gutter and the board. If you spot that on a sunny afternoon with wasps going in and out, you have almost certainly found the way in.
Why reaching the gutter line is risky
The fascia seems close enough to touch from a stepladder, and a lot of people are tempted to do just that. In reality you would be standing with your face a few inches from the entry, with the ladder resting against the gutter, which is not built to take weight.
A gutter that gives way while you are holding it is a hazard on its own. Add a group of wasps that has been disturbed by the movement, and a minor household job becomes a fall risk. Plastic gutters crack, and old metal ones come away from their brackets.
The technician works with the correct access equipment, and has the training to approach the roof edge without alerting the colony. That is a far better option than a borrowed ladder.
Do not fill the gap behind the board
When the entrance is hidden behind a gutter, the urge to squirt filler along the joint from below is strong. It is also misguided. The wasps are inside, and a blocked entrance simply sends them in search of a new one, which may be inside the soffit, behind the plasterboard or at a ceiling.
Equally, do not pull the gutter away to look. Doing so exposes the cavity and can send the colony into a defensive frenzy. Anything that shakes the fascia board shakes the nest.
Leave the board alone, and when the nest has been treated, a carpenter can replace a rotten section or fix the joint properly, which closes the gap for good.
Keeping the household safe in the meantime
Sit and eat away from the gutter line, and move chairs, bins and play equipment out from under the roof edge. Keep windows shut on the nest side, particularly upstairs, where wasps often wander to the glass.
Take care when cleaning the gutter. Clearing leaves and moss is a normal chore, but it must wait until the nest has been dealt with, since the vibration and the closeness are exactly what the wasps react to.
If someone is stung, wash the skin gently, remove the sting where it is visible and put a cold pack on it. Dial 999 straight away if breathing becomes difficult, or the face, lips or throat begin to swell, or the person feels dizzy or comes out in a rash across the body. Anyone with a known allergy should tell the office when booking so the visit can be prioritised.
Price, booking and the repair afterwards
For a single nest the fixed charge is £120 per nest, and attendance is not charged separately. A second nest on the same property is simply £60 extra. Nothing is added for the roof edge being high, and the price graphic carries a one visit guaranteed line. You pay the same at the weekend or in the evening as on a weekday morning.
The business is open seven days a week with same-day service, so a nest can often be reached quickly. Ring 01622 410 019 or use the online form on the contact page, which is also the way to raise an emergency outside office hours. The technician is fully insured and qualified, and homes and businesses are both covered.
After the visit, stray wasps may circle the old gap for a while. Ask the technician whether the empty nest can come down. Then book a joiner or roofer to fix the fascia joint, so that next spring's wasps find a solid board.
If the fascia has been covered with a plastic cladding, the gap may be even harder to see. Tell the office what you can about the type of board and the gutter, as it helps the technician pick the right approach before arriving.
