Bee or Wasp Sting: Normal Reaction vs Allergy, and When to Go to the ER

In Jordan, wasps and hornets are busiest in summer and autumn, gathering around ripe fruit, rubbish bins, sweet drinks and food at outdoor gatherings and picnics. With the grape and fig season and the start of olive picking, plenty of people get stung in orchards or on the balcony. Most stings hurt but aren't dangerous, while a small number of people are allergic to the venom and can become seriously unwell within minutes. This guide explains how to treat a sting, how to tell normal swelling from a large reaction or anaphylaxis, and when you need a doctor or the ER.

What should you do straight after a bee or wasp sting?

Based on advice from the NHS, MedlinePlus and the American Academy of Allergy, Asthma & Immunology (AAAAI):

1. Move away calmly — wasps can sting more than once, and a disturbed nest brings others.
2. Remove any stinger quickly. Honeybees leave their stinger and venom sac in the skin; wasps and hornets usually don't. Scrape it out sideways with a fingernail or the edge of a card — don't use tweezers or squeeze it.
3. Wash the area with soap and water.
4. Apply a cold pack or ice wrapped in a cloth for at least 20 minutes, and raise the stung limb.
5. Take off rings and watches if the sting is on the hand, before the swelling builds.
6. For pain and itching, ask a pharmacist about a painkiller such as paracetamol or ibuprofen, and an antihistamine or hydrocortisone cream. Don't give aspirin to anyone under 16.
7. Don't scratch — it can lead to infection — and skip home remedies such as bicarbonate of soda.

Is it a normal reaction, a large local reaction or anaphylaxis?

The key difference isn't how big the swelling is, but whether symptoms stay around the sting or affect breathing, the throat and the whole body:

The American Academy of Family Physicians (AAFP) describes a large local reaction as redness and swelling over 10 cm that spreads to the parts of the body next to the sting. It can look dramatic, but it stays in that area and doesn't cause breathing problems. Anaphylaxis usually starts within minutes of the sting. For the full list of signs and what to do, see our guide to allergic reactions and the signs of anaphylaxis.

When does a bee or wasp sting need the ER?

Call 911 for

• Difficulty breathing, wheezing, fast breathing or a choking feeling.
• Sudden swelling of the face, lips, tongue or throat, a tight throat or difficulty swallowing.
• Dizziness, fainting or sudden confusion, or skin or lips turning blue, grey or pale.
• Hives spreading over the body together with any of the above, or with vomiting and tummy pain.
• A sting inside the mouth or throat.
• Many stings at once, for example from a swarm of bees or wasps.

If you've been prescribed an adrenaline auto-injector, use it straight away at any sign of a serious reaction, then call 911 — even if you feel better.

Go to the ER now

• You've had anaphylaxis from a sting before and have been stung again — even if no symptoms have started.
• Hives or itching spreading away from the sting, or vomiting, tummy pain or light-headedness after a sting.
• Several stings in a young child or an older adult.
• Swelling spreading fast in the first hours and reaching towards the neck or face.

Urgent care or a doctor the same day

• A sting near the eye or on the eyelid.
• Signs of infection after a day or two: spreading redness, heat, pus, a fever or swollen glands.
• A large reaction that is getting worse after a few days instead of better.
• A sting in a baby under 1.
• A stinger you can't get out.

Home care is usually fine

• A single sting with pain and a red, swollen lump only around it.
• A large local reaction with no breathing, throat or whole-body symptoms that starts to improve after a couple of days.

How can you avoid wasp stings in summer and autumn?

• Cover food and sweet drinks when eating outdoors, and check inside cans and cups before you drink.
• Keep bins closed and away from where you sit, and pick up fallen fruit in the garden.
• Wear closed shoes on grass and in orchards, and avoid strong perfumes.
• If a wasp comes close, move away slowly rather than swatting it, and keep clear of nests and beehives.
• Anyone with a known sting allergy should carry their adrenaline auto-injector at all times — ideally two.

A scorpion sting is a different situation from a bee sting, with its own danger signs, especially in children; read our guide to scorpion stings and snake bites in Jordan. For bites from animals rather than insects, see our guide to dog and cat bites and tetanus.

What happens when you come in?

If there is any sign of a serious reaction, the emergency team starts treatment straight away, then keeps you under observation for several hours, because symptoms can come back. For a large local reaction, a sting near the eye or an infected sting, urgent care sees walk-ins 24/7: the doctor examines the sting, removes any stinger left behind, advises on easing the swelling and itching, and decides whether you need antibiotics. If you've had a whole-body reaction to a sting, ask to be referred to an allergy specialist afterwards.
