Wasps Around Your Guttering and Fascias? How to Find the Nest in Swanley
The sloping boards at a gable end, called bargeboards, form a long sheltered edge where wasps can slip in at the top corner or along the run.
What a bargeboard is and why it matters
Where the roof of a house ends at a side wall in a triangle, the sloping boards that run up each side are bargeboards. They do a job similar to a fascia, finishing the roof edge, but they sit at an angle and often at a considerable height. At the top, where they meet, and at the bottom, where they reach the gutter, there are corners that can leave gaps.
Wasps can nest in the void behind a bargeboard just as they do behind a fascia. Because a gable end is often the tallest part of the house, the nest may be well out of sight, and the first sign is simply wasps rising up the wall.
Gable ends also come in different forms. Some are plain, some have decorative timber, and some have a small overhang. Whatever the style, the principle is the same: look for a gap where the edge meets the wall or the tiles, and watch for wasps.
Reading the slope
Watching a gable end is a little different from watching a flat fascia. The boards slope, and wasps may travel up and down the line before entering. Follow a single insect with your eyes, if you can, and see where it goes.
- Entry at the apex, where the two boards meet at the top.
- Entry at the lower end, near the gutter or the corner of the wall.
- Entry along the run, at a lifted or split section.
- Entry at the junction with the wall, where the board has pulled away.
A good habit is to scan from the bottom of the slope up to the apex slowly, pausing every metre or so. Your eye is drawn to movement, so a wasp flying into a dark spot will often catch your attention if you are patient.
Keep in mind that a long gable slope gives wasps many potential entry points, and one nest can have more than one entrance. Note each gap where you see traffic and give them all to the technician.
Why it is tricky from the ground
Gable ends are high, and the angle from the ground is steep. It can be hard to judge whether wasps are going into the board or the wall behind it. If you can see well from an upstairs window of a neighbouring room, that may offer a better view, but do not open the window.
Even so, please stay away from ladders. The height involved makes a fall especially dangerous, and a gable edge is a difficult place to reach. A technician comes with the right kit to work safely at this height.
The sun can also make this harder, as a pale sky behind a dark board dazzles the eye. Try viewing in the morning for a west-facing gable, and in the afternoon for an east-facing one, when the wall is lit but the sky is not behind it.
Binoculars are the most useful tool here, because they flatten the distance and let you pick out the dark gap against the pale board without moving closer. If you do not own a pair, a neighbour may be happy to lend one, and it is a good item to keep in the house for this sort of job.
Indoor clues
Sometimes the best evidence is inside. A loft space or bedroom at the gable end may have a faint rustling or humming in the wall. Wasps can find their way through small gaps to the inside, and an occasional wasp at the window may be a clue.
If wasps do appear indoors, close the door of that room, keep other windows shut, and leave one window clear so wasps can be encouraged toward the light. Do not squash them against the wall, as that can attract others.
It helps to know which room lies behind the gable. If it is a loft or an attic bedroom, keep the door closed and the window shut until the nest is treated, and avoid using the room in the evening if you can hear activity.
Treatment and what follows
The price is fixed at £120 per nest, regardless of height, with no call-out charge and no extra for time of day. One visit is guaranteed, according to the price graphic, and a second nest on the same property is £60 extra. The technician is fully insured and qualified and the work is safe and effective.
Once the colony is inactive, have the board checked, because older bargeboards can warp or crack. A roofer or builder can replace a damaged section or fill small gaps, and it is wise to ask them to look at the whole slope.
If the gable has timber boards that have been weathered for years, the roofer may suggest replacing the whole length rather than patching it. That is a reasonable approach, as old timber tends to open up in several places at once.
Booking in Swanley
Phone 01622 410 019 or fill in the booking form on the contact page. The office is open seven days a week with same-day service for homes and businesses, plus evening and weekend slots. Mention if anyone is allergic to stings so the booking can be prioritised.
When you call, say which side of the house the gable is on and what is directly beneath it. Ask the technician whether the empty nest can be taken down.
If you are able to say how many storeys the gable rises above the ground, it helps the technician bring the correct equipment. A rough description is enough.
