Found a Wasp Nest in Your Loft in Arthington? Here's What to Do
Ceiling stains and scratching noises are easy to blame on damp or mice. They are also classic early warnings of a wasp nest above.
The mistake: blaming damp, mice or the pipes
A faint scratching, a soft rustle or a brown mark spreading across the ceiling is something most householders explain away. Damp, old pipes, mice in the roof or the house settling are all plausible and all more familiar than a wasp nest. The mistake is to carry on with that explanation for weeks, because a nest builds steadily and the evidence gets louder as it does.
Wasps chew wood fibre and mix it with saliva to make the paper that forms a nest. A nest that presses against a ceiling can leave marks on the surface above it, and the sound of chewing and movement can be heard through plasterboard. If those sounds only occur on warm days, or build through the afternoon, that points to insects rather than pipes or rodents.
In Arthington, as elsewhere, the sensible thing is to treat unexplained loft noises in spring and summer as a possible nest until you have ruled it out.
Timing is a useful clue as well. A nest in its early stages makes very little noise, and the first sign may be a couple of wasps on the window of the room below. As the colony matures, the sound grows and the staining can follow. If your house has gone from quiet to noisy in a matter of weeks during summer, a growing nest is the most likely explanation.
Checklist: stains, sounds and smells
Look for a pattern rather than a single clue.
- A brown or yellowish patch on the ceiling that grows over a few weeks and does not follow a plumbing line.
- A dry, papery scratching, as opposed to the heavier thump of a larger animal or the drip of water.
- A hum that rises when the room warms up.
- A small number of wasps in the room below, particularly near the stain or a light fitting.
- A faint, sweet or musty smell that you cannot trace to anything else.
- No sign of the stain spreading after rain, which suggests the cause is not a roof leak.
If you tick more than one, treat it as a nest until proven otherwise. Do not press on the stain or poke at the ceiling to see how soft it is, since that can disturb the nest directly above.
How to tell wasps from mice and damp
Rodents tend to be active at night. They produce thumping, running and gnawing sounds and may leave droppings. Wasps are active in daylight and quiet at night. If your noise stops after dark and starts as the sun warms the roof, it is more likely to be insects.
Damp usually follows rain. A stain that gets worse after a downpour and dries slowly is likely to be a leak. A stain that develops steadily in dry weather, with insects nearby, is another matter.
You do not need to be certain before calling. If you describe the noises, the stain and any wasps you have seen, we can tell you whether it sounds like a nest. If it turns out to be something else, such as a pipe or a rodent, you will need the relevant tradesperson instead, because we deal with wasps only.
What to do while you wait
Leave the ceiling alone. Do not push a broom handle up, drill into the plaster to look, or cover the stain with paint until the cause is known. Keep the hatch closed, and avoid heavy footsteps or banging in the room below, since vibration is carried through the structure.
Keep the affected room quiet and, if wasps are coming through, closed off. Turn off lights there at night. Cover food and drinks. If anyone is stung, wash the sting, remove it if visible and use a cold pack, and call 999 for swelling of the face, lips or throat, wheeze, difficulty breathing, dizziness or a widespread rash.
Take a clear photograph of the stain and note the date. If it grows, that gives the technician useful information and shows how quickly the nest is developing.
If you notice the stain darkening or a patch of ceiling starting to bulge, keep everyone out of the room and mention it when you book. Do not try to cut into the plasterboard to see what is behind it. That is the one step most likely to release a lot of wasps into the house at once.
The treatment visit and afterwards
A trained, fully insured technician will locate the nest and treat it. You do not need to go into the loft, and we ask that you do not. Once the visit is done, the wasps will gradually stop appearing, though you may see a few near the old entrance for a short time.
A ceiling stain will not disappear by itself. Once you are confident the nest is dealt with, you can think about repairing and repainting. If the plasterboard looks soft, ask a builder to check it. Dead wasps should be brushed up with gloves and put in the bin. The empty paper nest can usually stay where it is; if you would like it taken down, ask us when you book whether that is possible.
