Treating a Wasp Sting

What helps, what doesn't, and when it stops being minor.

First, the emergency check

Dial 999 without waiting if the person who was stung has any of the following, or was stung inside the mouth or throat:

  • Wheeze, noisy breathing, or a struggle to breathe
  • A swelling face, tongue, lips or neck
  • Trouble swallowing or a feeling of the throat closing
  • Light-headedness, collapse, or sudden confusion
  • Hives or blotching spreading well beyond the sting

This is anaphylaxis. Minutes matter, and it does not settle on its own.

The routine sting

Nine hundred and ninety-nine stings in a thousand are painful, infuriating and medically trivial. The venom does its work in the first few minutes; everything after that is your own inflammation, which is why cold and antihistamines are the useful tools. Do these five things, in this order:

  1. Get clear of the wasp, calmly. A sting deposits an alarm scent that recruits nearby nest-mates, so a slow, deliberate walk indoors beats any amount of arm-waving.
  2. Wash the site with soap under running water. Unlike a honeybee, a wasp leaves nothing embedded, so there is no extraction step.
  3. Chill it. Ten to fifteen minutes with ice in a tea towel, or even a cold drinks can, takes the edge off the pain and restrains the swelling.
  4. Treat the symptoms you have. Ordinary painkillers for the ache; a pharmacy antihistamine, tablet or cream, for the itch that arrives later.
  5. Keep an eye on the person for thirty minutes. Dangerous reactions announce themselves early. If the half hour passes with nothing beyond local pain and redness, serious trouble is very unlikely.

Things people do that don't help

  • Vinegar. The idea that acid neutralises wasp venom is folklore; the venom is already under the skin where no surface liquid reaches it. Cold works better.
  • Sucking or squeezing the sting. Achieves nothing except bruising an already sore spot.
  • Scratching. The itch phase lasts days, and broken skin is how stings become infected. Antihistamine cream exists for exactly this.
  • Ignoring a sting near the eye or in the mouth. Stings to the tongue, throat or airway need medical advice even in a non-allergic person, because ordinary swelling in those places is itself a hazard.

Who needs extra caution

A few groups deserve a lower threshold for seeking advice. Babies and toddlers cannot describe their symptoms, so watch them more closely and check medicine doses carefully; aspirin has no place under sixteen. During pregnancy, stick to paracetamol and run any antihistamine choice past a pharmacist. Older people, and anyone on blood thinners or steroids, tend to swell more and heal slower, so infection is worth watching for: spreading warmth, pus or a fever developing a day or two after the sting means a GP call.

Dogs and cats

Pets hunt wasps and pay for it. A pawful of venom means a limp and some licking, and passes with a cold compress and observation. The dangerous version is a snap that catches the wasp in the mouth, because swelling near a dog's airway is as serious as it is in ours. Mouth or throat stings, repeated vomiting, wobbliness, or visible distress justify an emergency vet call rather than waiting overnight.

The sting is a symptom; the nest is the cause

A sting in your own garden usually means a colony within a couple of hundred metres, and often within twenty. Trace the flight line: foragers leaving a nest fly straight, so a repeated bearing towards one corner of the roof, one air brick, or one hole in the lawn will give the game away in a few minutes of watching. Once you know where it is, stay back and leave the approach to us.

Frequently Asked Questions

The sharp burning phase is short, typically gone within an hour or two. What follows is a red, itchy bump that can hang around for several days. If a whole hand or forearm balloons, that is called a large local reaction; it looks alarming but stays in one area and settles over a week or so with antihistamines and cold compresses.

Not from a wasp. Their sting is smooth and reusable, which is also why one wasp can sting several times. Finding a barb left in the skin means the culprit was a honeybee; ease it out by scraping across the skin with something flat rather than gripping it, which squeezes the venom sac.

Yes, and the first uneventful sting is sometimes what primes the immune system. A person can develop sensitivity at any point, so every sting deserves half an hour of watchfulness regardless of history. Anyone who has previously had swelling beyond the sting site, hives, or breathing trouble after a sting should speak to their GP about allergy referral and carrying an adrenaline pen.

Venom is toxic in volume even without allergy. As a rule of thumb, ring NHS 111 after ten or more stings to an adult, five or more to a child, or any number if the person feels sick, dizzy or generally unwell afterwards. Treat mass sting events, dozens at once, as a 999 call.
