Wasp Nests Under Roof Tiles – A Common Problem for Kirk Sandall Homes
There is a right moment to repair the gap a nest has been using, and it is not while the colony is still alive behind it.
The repair that is easy to get wrong
A householder who spots wasps going into a gap in the roof naturally thinks of repair. The impulse is a good one, since a sealed roof is the best protection against future nests. The mistake is in the timing. Filling the gap while a nest is alive does not remove the nest. It only changes where the wasps go.
The colony inside is still alive and still needs a way out, and wasps will explore every possible route to find one. The routes available behind tiles and eaves tend to lead down into the building: through wall cavities, around light fittings, through loft hatches and along pipes. Many a household has gone from a few wasps at the roofline to a handful in the kitchen overnight, simply because the entrance was blocked.
The same applies to any quick fix at the entrance, including foam, sealant, tape, wire wool or a rolled-up cloth. They all do the same thing, which is to close a door that the colony is still using.
What goes wrong in practice
The pattern is predictable. Workers coming back from foraging find a closed door, cluster in a bad-tempered group and try the nearest alternatives. Inside, wasps keep emerging and move through the building to find daylight. Anyone nearby, including the person who did the repair, is exposed.
- The sealed entrance becomes a gathering point for angry wasps.
- New routes open up inside the house, usually in the rooms closest to the roof.
- The nest keeps growing, because blocking the entrance does nothing to the queen or the brood.
- Eventually, the wasps chew through something softer, such as plasterboard or a flimsy seal.
The upshot is a worse situation than before, with a nest that is now harder to reach because the original route has been hidden.
Not every case ends in wasps indoors, but it is common enough that the safest advice is never to take the chance.
The wasps are not trying to harm you. They are simply following the colony’s need to get in and out. That need does not go away because the entrance has been closed, and a few layers of paint or a plug of filler do nothing to change the situation inside the roof.
The right order of events
The sequence that works is straightforward: treat first, wait, then repair. The details look like this.
- Treat the nest. Have the nest dealt with by a technician, with the entrance left open.
- Wait for activity to stop. This usually takes a day or two. A few returning wasps are normal.
- Check the entrance. Once no wasps have been seen for a couple of days, you can be fairly sure there is nothing left behind it.
- Repair the gap. Use a suitable material for the location, or call a roofer if it is high up.
- Check for other gaps. Walk round the roofline and note anything else a queen could use next spring.
If you are unsure whether the activity has really stopped, ask the technician, who will tell you.
If the entrance is high up, repair should not be a DIY job in any case. A roofer can do it safely, and they will usually be happy to look at the whole roofline at once.
Repairing too early may feel like progress, but it wastes materials and effort, since the seal may have to be broken again. Doing it once, in the right order, is cheaper and safer.
What if the gap has already been sealed?
If you have already filled or covered the hole, do not panic and do not try to undo it from a ladder. Leave it alone and tell the technician when you book, including when you sealed it and what you used. They can then see where the wasps are heading and decide how to proceed.
Keep a close eye on the rooms below the nest. Close doors on the top floor, keep windows nearest the roof shut if you can and avoid leaving the loft hatch open. If wasps begin to appear indoors in numbers, stay calm, move away from them and let the technician know.
Do not be tempted to compensate by sealing more openings in the house. That makes the interior routes harder for the wasps to use, but it also traps them in the cavities and walls, where they may find yet another way into a room.
If the numbers are growing or there are signs of a serious reaction in anyone, call 999 for swelling of the face, lips or throat, wheezing, dizziness or a widespread rash.
