Are Wasps Dangerous? Understanding Stings and Nest Disturbance in Chadwell Heath
Wasps drawn by lamps and open windows can turn up in the bedroom, and the half-light of evening is not a good time to deal with a nest.
Why wasps appear indoors in the evening
A warm evening with the window open and the lights on is an invitation. Wasps, like many insects, are drawn to light, and one that has spent the day foraging may find itself in your bedroom or living room rather than back at the nest. It crawls up the glass, circles a lamp, and buzzes in a way that is hard to ignore.
A stray wasp in a room is usually lost, not hostile. It wants to get out, and the best help you can give is a clear route. Switching off the lamp, opening the window wide and leaving the room often works.
A steady stream of wasps coming in is different. That can mean a nest in the wall, the roof void or the eaves nearby, and it calls for more than opening a window.
A typical evening goes like this: the window is open, the lamp is on, and by ten o'clock there are two wasps circling the ceiling light. By the following evening there are four. This steady rise suggests wasps are finding a way in from somewhere close, and a nest in a nearby wall or roof edge is a real possibility.
What to do about a wasp in the room
Stay calm and avoid swatting. Wasps tend to sting when they are trapped or hit.
- Switch off the light in the room and open the window as wide as possible.
- Move away from the window and wait. A wasp usually heads towards the daylight or the open air.
- If it will not leave, use a cup and a piece of card to catch it gently, then release it outside.
- Check bedding, towels and shoes before using them.
- Close the window again once it has gone.
Do not swing a rolled-up newspaper or a slipper. A missed swat is likely to provoke the wasp and could result in a sting.
Check the places the wasps seem to originate. Wasps near a loft hatch, a bathroom extractor fan, a gap by a pipe or a bedroom ceiling rose may be coming in through the building rather than the window.
Dusk is not a safe time to look for a nest
Some people try to find the nest in the evening, thinking that wasps are quieter then. It is not a good idea. Poor light makes it harder to see where you are standing, a ladder is more dangerous, and you cannot judge how many wasps are around the entrance. A torch can draw wasps towards you as well.
Watching traffic in good daylight is the right way to find an entrance. Stand a good distance away, choose a calm moment and note where the wasps land. Do this from the ground, not from a window ledge or a stepladder.
If you suspect a nest above a bedroom window, keep the window closed in the evening and draw the curtains. Do not lean out to look.
Wasps in a bedroom are more worrying if the sleeper is a child. Keep their door closed, and check bedding before bedtime.
Night-time stings
A sting in the night, for example from a wasp that has crawled into bedding, is a shock but usually manageable. Get out of bed, move away from the wasp and put the light on.
Wash the area, remove any visible sting and apply a cold pack. Stay up for a while and watch how you feel, rather than going straight back to sleep. A partner or family member should be told.
Any of swelling of the face, lips or throat, a widespread rash, dizziness or wheezing or difficulty breathing means an emergency call to 999. If anyone in the home has a known allergy, make sure they know where their medication is kept, including at night. This section does not replace advice from a doctor or pharmacist.
Fly screens and fine mesh at open windows are effective, as are curtains drawn before the lights go on. A wasp that cannot see the light is less likely to wander in.
Reducing the chance of wasps indoors
A few habits help. Close windows when the light is on, or use fine mesh screens. Draw the curtains before putting on lamps near open windows. Keep sweet drinks and food covered or put away at night, and rinse cans before putting them in the recycling.
Check for gaps around window frames, vents and pipes. Do not seal these if a nest is nearby, because sealing an occupied gap can send wasps into the house. Wait until the nest has been dealt with.
Wasps start building from late April, depending on the weather, and by August a nest may hold 2,000 to 10,000 or more wasps. The sooner you notice a pattern, the easier the problem is to manage.
If a wasp lands on you in the dark, stay still, put on the light and let it leave. Moving suddenly is more likely to prompt a sting.
