Wasp Nests Under Roof Tiles – A Common Problem for Ravenfield Homes

The treatment visit is quick, but the days afterwards bring their own questions, from stray wasps to the empty nest and what to repair before next spring.

The first hours and days

When the technician has finished, the nest is dealt with, but life around the roof does not return to normal at once. Workers that were out foraging when the nest was treated will come back to find nothing there. They hover and circle around the old entrance, and some will wander into rooms nearby. This is expected, and it usually lasts a day or two.

Keep windows on that side of the house closed for the first day if you can, keep an eye on children and pets in the garden and avoid standing directly under the old entrance. You may notice a handful of dead wasps on the ground below, on window sills or in the gutter. Pick them up with gloves or sweep them away, since a dead wasp can still sting if it is trodden on or handled.

It can help to think of the old entrance as a place to avoid, just as you did before treatment. Hang the washing elsewhere for a day or two, and keep children away from the wall.

What to expect and when to call

It helps to know what is ordinary and what is not.

• Normal: a few wasps circling the old entrance, some dead wasps near the wall, and an odd one indoors in the first day or two.
• Worth mentioning to the technician: a sustained stream of wasps still entering the gap after a couple of days, or fresh activity in a different spot.
• Worth a roofer: a damp patch or a stain that grows after rain, which points to a roof problem and not to the wasps.

If you are stung, wash the area, remove the sting if visible and use a cold pack. Call 999 for swelling of the face, lips or throat, wheezing or difficulty breathing, dizziness or a widespread rash. People with known allergies should speak to their GP.

If you are unsure about something you are seeing, a short phone call or message to the technician is better than worrying. Describe what you see and when it started, and they will tell you whether it is normal.

Keep a note of how many wasps you see on the first and second day. A clear drop is the sign that all is going as it should, and it gives you something concrete to tell the technician if you do need to call.

The empty nest

The nest is a papery structure made from chewed wood fibre, and it stays where it was built unless someone removes it. Under tiles or inside an eaves cavity, it is often out of sight and out of reach, and you may never need to think about it again.

Wasps do not reuse an old nest, so it poses no direct risk. Even so, some householders prefer to have it taken down, and if that is you, ask the technician at the time of booking whether it is possible in your case. Do not assume it will happen, and do not attempt to pull it out yourself from the roof or a ladder.

Sometimes the nest ends up loose in a cavity. It is lightweight, and it may rattle slightly in wind. That is harmless, but if the noise bothers you, mention it to a roofer when they look at the repair.

Whether a nest can be reached for removal depends on where it is. Nests behind tiles or inside a cavity may be impossible to take down without opening up the roof, which is a roofer’s job, so the answer may be to leave it where it is.

Repairs and prevention

Once the wasps have stopped flying, the entrance can be sealed. This is the single most useful step you can take against another nest. Look at the gap the wasps used and think about what caused it, such as a crumbling joint, a loose tile edge, a cracked vent or a warped board.

For something low and simple you may be able to do the job yourself with a suitable filler or mesh. For anything at roof height, a roofer is the sensible option. They can also look at the wider roofline and spot other weak points.

Make a note to check the outside of the house in early spring and again in late May. A few wasps flying in the same direction around the roofline in April or May suggest that a queen has chosen a spot, and an early call is simpler for everyone. The price is the same whenever the nest is treated.

When the repair is done, a quick tidy of the gutter and the ground below finishes the job. Remove any papery debris and dead wasps, and enjoy the quiet.
