Autumn: nests dying off

Wasp stings and allergy

For breathing trouble, swelling of the mouth or throat, collapse or a suspected severe allergic reaction, call 999. Follow prescribed emergency medicine instructions. Use NHS advice for other sting symptoms; this page does not diagnose a reaction.

Most wasp stings are painful but harmless. A small number of people have a serious allergic reaction, which is a medical emergency. This guide explains the warning signs and where to get help. It is not medical advice; always follow NHS guidance and your own doctor.

NHS: anaphylaxis

Call 999 for these signs

Call 999 straight away if someone has any of these after a sting:

  • Difficulty breathing or wheezing
  • Swelling of the lips, tongue, mouth or throat
  • Feeling faint, dizzy or confused
  • Collapse or loss of consciousness
  • A fast heartbeat with clammy skin
  • A rash spreading over the body with any of the above

If the person has an adrenaline auto-injector

If they have been prescribed an adrenaline auto-injector, use it as instructed and still call 999. Follow the instructions given by the call handler.

Normal sting reactions

A typical sting causes sharp pain, redness and swelling around the spot. Some people get a larger local reaction, with swelling spreading over a wider area for a day or two. Large local reactions can be uncomfortable but are usually not dangerous. Speak to a pharmacist or NHS 111 if you are worried.

Living near a nest with a known allergy

If anyone in your home has had a serious reaction before, an active nest near doors, paths or the garden is a higher risk. Keep them away from the flight path and treat the nest sooner rather than later.

Tell us about the allergy when you call so we can plan the visit, and keep that person indoors while we work.

Reducing the chance of stings

  • Cover drinks outdoors and use a straw
  • Keep bins closed and clear up fallen fruit
  • Do not swat at wasps; move away calmly
  • Wear shoes on the lawn in late summer
  • Do not mow or trim near a known nest

    Sting first aid

    Follow NHS advice for insect stings. Severe allergic symptoms need emergency medical help, not a nest-treatment booking. Call 999 for breathing difficulty, throat swelling or collapse.

    What if you leave a nest?

    A colony normally declines as the season ends. Whether to leave an active nest depends on its position and the risk to people nearby. A flight path beside a doorway is different from one in an unused corner. Do not disturb it to check.

    Signs of a wasp nest

    Repeated flights into one gap are more useful evidence than a single wasp near food. Look at roof edges, vents and garden structures from a safe position. Do not climb up or dismantle anything to investigate.
