Wasp Nests Under Roof Tiles – A Common Problem for Womenswold Homes
The hole you can see is rarely the nest itself. This guide explains why the entrance and the nest can be some distance apart, and how that affects what you do.
A small hole and a larger story
When wasps are seen entering a gap in the roof, most people picture the nest just behind it. Often it is not. The opening is the front door, and the nest can be set some way into the roof space, along a cavity, or tucked into a corner above a ceiling.
Wasps will happily travel a distance inside a void to reach a place they like. They follow gaps between timbers, along the back of a fascia or through the layers of an eaves detail, and the nest ends up some distance from the point where you see them.
This is why a roof nest in Womenswold, or anywhere else, can be found in a different place from the one you point to.
A roof void can be a surprisingly large space. Rafters, purlins, insulation and boarding create channels and pockets, and wasps use them like corridors.
What this means for what you see
The traffic you watch is a clue to the entrance, not the nest. A few consequences follow from that.
- Plugging or covering the visible hole will not reach the nest, only the exit.
- A second hole some way along may be a back door, not a second nest.
- The sound may come from a different part of the roof from the entry.
- Wasps inside the house may emerge far from the point where they entered outside.
You do not need to solve the puzzle. The technician will do that on the day, using experience of how roofs are put together.
This is also why watching the entrance for a long time does not reveal the size of the nest. Entry traffic reflects how many workers come and go, not how far in the nest sits.
Why guessing is risky
Some people respond to this uncertainty by taking action based on a guess. They press on the ceiling where they hear the noise, or lift a tile where they think the nest is. Both can lead to a colony being disturbed at close range.
A nest that is a metre from the hole you can see is still close enough to react. A knocked tile, a drilled hole or a hammered board all send vibration through the roof structure.
It is wise to leave every part of the roof alone and let the person who is trained to read it do so.
People sometimes ask whether they should open the loft hatch to check. The answer is a firm no. If the nest happens to be near the hatch, you will meet the colony at close range.
Drilling a small hole to peek inside is another idea that circulates. It is a bad one, for the same reason: it opens the nest to the air and puts your face at the gap.
Describing what you see usefully
You can help by giving the technician good information about the entrance, even if you cannot say where the nest is. Note where the wasps go in, which way they fly out, and whether the traffic seems heavier at some times than others.
Say if you have heard noises in the ceiling and in which room. Mention any stains or wasps indoors, and say where. These details help to narrow down where the nest might be, since the indoor clues sometimes point further along the roof than the outdoor ones.
A photograph from the garden can be useful, as can a short video of the traffic.
If you are unsure whether two entrances belong to one nest, say so, and mark them on a photograph. The technician will appreciate the honesty more than a confident guess.
Keeping safe while the position is unclear
Treat the whole length of the affected roof edge as the danger zone. Keep clear of the wall below, and keep children, pets and washing away from it. Windows on that side of the house should be shut.
Do not block the entry to try to hold the wasps in. That can drive them along the void to a different exit, and the new exit may be inside.
Should anyone be stung, clean the spot, lift out any visible sting and put a cold pack on it. Phone 999 without delay if the face, lips or throat swell, or there is wheezing or difficulty breathing, or if there is dizziness or a rash spreading across the body.
Think about the people who use the rooms under that stretch of roof as well. A bedroom directly below the cavity is worth keeping closed until the visit.
If wasps appear in an upstairs room, note which room and when, and tell the office. It helps the technician decide where in the roof to look.
Price, booking and afterwards
You pay one fixed price of £120 per nest, without any call-out cost. An additional nest on the same property is £60 extra, no more. The price graphic confirms that one visit is guaranteed, and it makes no difference whether the nest is near the entrance or further in.
Booking is by phone on 01622 410 019 or via the contact page form, which is also the route for urgent cases when the office is closed. The business operates seven days a week with same-day service and evening and weekend slots, and its technicians are insured and qualified to work on domestic and commercial roofs.
Afterwards, wasps may continue to circle the old entrance briefly. Ask the technician whether the empty nest can be taken down, and have a roofer repair the entry and any nearby weak spots.
Whatever the distance between hole and nest, the price is the same, so there is nothing to gain from trying to guess the position first.
