Found a Wasp Nest in Your Loft in Stonebridge Green? Here's What to Do
Light fittings and cable holes give wasps an easy route out of a loft, so a wasp at a downlight usually means a nest in the roof space above.
Why lights are an exit
A ceiling light is more than a fixture. Behind it there is a hole through the plasterboard, a gap around the cable and a path into the roof space. For a wasp wandering in the loft, that gap is a way down. Spotlights and downlights, which need larger holes, are particularly leaky, but even a simple ceiling rose can have a gap around the edge.
If wasps are appearing at a light, circling it or dropping from it, it is a clear sign that they are coming through from the loft. Usually the nest is within a short distance of the fitting, although it is not necessarily directly above.
Think also about which light the wasps favour. Wasps that have come into a room generally head towards the brightest source, so a lamp left on at night can pull stragglers towards the ceiling fitting instead of the window. In the evening, switching the main light off and turning on a lamp near a window can help any wasp find its way out.
Safety around electrics
Electricity and insects do not mix. Do not remove the light cover to look, do not spray into the fitting and do not poke at it with a stick or screwdriver. Spray can enter the electrics, and fiddling with a live fitting is risky. If you want to stop wasps gathering there, simply switch the light off at the wall and leave it off.
Wasps are drawn to light and warmth, so turning off the lamp may reduce the attraction. Use another room's light or a table lamp instead. If you are in any doubt about the wiring, ask an electrician after the nest has been dealt with.
If you are renting or the wiring belongs to a landlord, tell them that wasps are using the fitting and that you have switched it off. It is not for you to take apart. A qualified electrician can look at the fitting after the nest has been dealt with, if needed.
Steps you can take
There is plenty to do without touching the fitting.
- Switch the light off at the wall and keep it off.
- Close the door of the room and open a window.
- Place a towel at the bottom of the door if wasps are spreading.
- Do not cover the light with tape or plastic, which can trap heat.
- Do not stuff the gaps with foam.
- Keep the loft hatch shut and nobody up there.
If a wasp falls into the room, let it leave through the window, or catch it under a glass and release it outside.
Where several fittings are involved, such as a row of downlights in a kitchen ceiling, note which ones attract wasps. The pattern can help the technician work out where the nest sits relative to the room, and whether it is large enough to be reaching more than one gap.
The role of the loft hatch and cable routes
Light fittings are not the only route. Cables, pipes, extractor fan ducts and the edge of the hatch all offer paths. A nest in the loft usually has more than one way down, but most of the wasps still prefer to use the outside entrance. If you see only a few at the light, it is a minor leak of a bigger colony.
That is why blocking the light gap is not the answer. You would be closing one path, and the wasps would find another. The proper answer is treating the nest.
Wasps can also come through extractor fans and their ducting, especially in bathrooms. Turn the fan off if wasps are appearing at the vent, and keep the door closed. As with lights, do not cover the fan with tape.
If you rent your home, let the landlord or agent know about the fitting, since electrical items may be their responsibility. Who deals with what depends on the tenancy agreement, so check it. The wasps themselves can be treated as soon as you book, without waiting for any repair.
A final reminder: keep children away from light switches and fittings while wasps are about. A child pressing a switch beneath a cluster of wasps is an avoidable accident.
Arranging treatment
We offer a fixed price of £120 for each nest, £60 for an additional nest on the same property, with no call-out charge and one visit guaranteed. The technician who attends is fully insured and qualified for the job. We are open seven days a week, offer same-day service, and have evening and weekend appointments.
Phone 01622 410 019 or use the online form on the contact page, including for emergencies out of hours. We cover Stonebridge Green and the surrounding villages, homes and commercial buildings alike. Mention which light fittings are affected, because it helps the technician decide where to look.
Afterwards
After treatment, dead wasps may lie in the light shade or on the floor beneath. Switch off the light at the wall, then wipe or vacuum the fitting carefully, once the technician says it is safe. Do not use water on a fitting.
If gaps around downlights concern you, an electrician or builder can advise on fire hoods and sealing. That is outside our work, but it is a sensible thing to ask about, since it may prevent insects and draughts from using the same route next year.
If you are wondering whether to use the room in the meantime, a few wasps do not make it unusable, but switching it off and keeping the door shut is the sensible approach. Use another room for sleeping or working if you can.
