Wasps Around Your Guttering and Fascias? How to Find the Nest in Cropston

A faint buzzing or rustling in a bedroom ceiling or upstairs wall can be the first sign of a nest in the roof edge, often before a single wasp has been seen outside.

When the sound comes before the sighting

Not every nest announces itself by a line of wasps in the garden. Sometimes the first clue is a low, steady hum coming from a bedroom wall, a landing ceiling or the corner of an upstairs room. It can sound like a distant fridge or a mobile phone vibrating on a shelf, and it often gets louder when the day warms up.

If your house is in Cropston or anywhere else, that kind of noise near the roof edge is worth taking seriously, especially in summer. A nest in the cavity behind the fascia or soffit can sit only a short distance from a bedroom wall, and the workers' activity carries through the plaster.

Wasps do not make a rhythmic, mechanical sound, so if you hear something that varies with the weather rather than ticking steadily, insects are a fair guess.

Listening carefully and safely

You can learn a great deal without touching anything. Switch off the television and the radio, stand in the quiet room and listen near the external wall. Note where the sound seems strongest, and whether it changes with the time of day. A hum that increases in the warm afternoon and fades by dusk suggests insects, not plumbing.

Do not tap the wall to see what answers, do not press a glass to the plaster and bang about, and do not drill or cut into it. Wasps defend the nest from any disturbance, and breaking into a wall gives them a new way into the room.

Instead, note the room, the wall, and roughly how high the sound seems to be. That is all.

Keep a small note on your phone of times and rooms. Even a few lines such as 'upstairs back bedroom, loudest around three, near the corner' gives a technician something specific to work from.

Now check the outside

With the room noted, go outside and look at the matching part of the exterior. Stand back and watch the section of fascia, soffit or gutter above that room for a couple of minutes.

• If wasps are entering a gap there, the nest is almost certainly the source of the sound.
• If you see nothing outside, the entrance may be on a different side or hidden by a gutter or a tree; keep watching on a warm afternoon.
• If wasps are appearing inside the room, around a window or a light fitting, the nest may have found its way into the building, and you should say so when you ring.

A nest need not be on the same wall as the noise, because the cavity can run around a corner.

Keep in mind that a gutter, a roof overhang or a thick hedge can hide an entrance from your view. If you cannot see it, do not worry. The technician is used to finding nests when the clues are limited.

Protecting the household meanwhile

Keep the door of the affected room closed, and if you can, use a different bedroom. Place a towel along the bottom of the door if wasps are getting into the room, and keep the window shut. Do not use fly-killer products on wasps in the room, since it will not solve the problem and may simply anger them.

Children and pets should be kept out of that room. If somebody does get stung, wash the area, remove any sting you can see, and use a cold pack. If they develop swelling of the face, lips or throat, wheezing, trouble breathing, dizziness or a widespread rash, call 999. People with a known allergy should speak to their GP in advance.

If wasps have appeared in the room, stay calm, avoid swatting, and leave the room by walking steadily out with the door closed behind you. They are more likely to leave you alone if you leave them alone.

What the booking involves

Wasp nest treatment is a fixed £95 per nest, with £35 for an additional nest on the same property. There is no call-out charge. We operate seven days a week, can offer same-day service, and work for both households and businesses. A trained technician attends, and the visit is fully insured.

Phone 0116 214 9259 or use the online form on the contact page. Tell us about the sound as well as anything you have seen outside, because it helps point to the nest. We confirm the price on the phone before the visit and do nothing without your agreement. If anyone in the home is allergic to stings, let us know when you book.

If you are away from the property at times, tell us who will be present on the day. We do not go ahead unless the customer has agreed the work, so it matters to know who to ask.

Once the humming stops

After treatment the noise should fade as the activity ends, though old nest material may stay in the cavity. If you would like to know whether the empty nest can be removed, raise it at booking.

Ask a builder or joiner to look at the outside of the roof edge and close the gap the wasps used. If the humming stops but you notice staining on the ceiling inside, or a damp smell, mention that to the tradesperson as well. These are separate issues but worth checking while someone is already looking at the roofline.

It is also worth ventilating the room once the activity has finished, and letting any smell of old nest material clear before you move back in.
