What to do
Minor sting (local reaction)
- 1Move to a safe area to avoid more stings.
- 2Remove the stinger if one is left — scrape or brush it out; getting it out quickly matters more than the method.
- 3Wash the area with soap and water.
- 4Apply a cold pack for about 10–20 minutes to reduce pain and swelling.
- 5Soothe itching with an over-the-counter anti-itch cream or medicine if needed.
- 6Watch the person for any sign the reaction is becoming more than local.
Severe allergic reaction (anaphylaxis) — emergency
- 1Call 911 immediately at the first signs — trouble breathing; swelling of lips, face, or throat; dizziness or fainting; weak, rapid pulse.
- 2Help the person use their own emergency allergy auto-injector as directed on the device — it's their prescribed medication for exactly this.
- 3Keep them calm, lying down (or sitting up if it helps breathing); loosen tight clothing.
- 4Be ready to begin CPR if they stop breathing.
- 5Stay with them until EMS arrives — symptoms can return even after the auto-injector, so 911 goes with every use.
When to use it
- Warm-weather outings where bees, wasps, and yellow jackets are active — around food, drinks, and trash especially.
- Fire-ant regions, where a disturbed mound produces many stings fast.
- Knowing before a trip which scouts carry auto-injectors — a health-form matter as much as a first-aid one.
Common mistakes & safety
- Anaphylaxis is the emergency you never miss. Trouble breathing or facial/throat swelling after a sting is a 911 call and an auto-injector, not wait-and-see — it can kill within minutes.
- Use the person's OWN auto-injector. Help them use it, then 911, and expect a reaction can rebound — which is why medical care always follows.
- A sting inside the mouth or throat can swell the airway even without an allergy — treat swelling that threatens breathing as an emergency.
- Multiple stings can be dangerous even without allergy. A disturbed hive or ant mound can make anyone sick — get medical help.
- Remove a bee stinger fast. Venom keeps pumping while it's in — speed matters more than scrape-vs-pinch.
- Prevention: avoid perfumes and bright florals, keep food and sweet drinks covered, don't go barefoot in clover, move away slowly from a hive, and check cans before drinking outdoors.
Going deeper
- Local vs. large-local vs. anaphylaxis. A normal local reaction is pain and swelling at the sting; a "large local" reaction can swell a whole limb over a day or two but isn't life-threatening; anaphylaxis is a whole-body reaction — that's the emergency.
- The auto-injector buys time. It delivers the first-line emergency medicine for anaphylaxis, but using it does not replace calling 911.
- Honeybees vs. wasps. A honeybee leaves its barbed stinger and dies; wasps, hornets, and yellow jackets keep theirs and can sting many times — which is why disturbing a wasp nest is so dangerous.
