For most stings from bees, wasps, or hornets, the right response is simple: remove the stinger if one is present, clean the area, apply something cold, and manage pain and swelling at home. The majority of stings cause only local reactions that resolve within a few days. Knowing the steps, and knowing when a sting is more serious, can make the difference between a calm recovery and a trip to the emergency room.
Immediate First Aid for Insect Stings
If you’ve been stung by a bee, check the site for a stinger. Bees leave their stinger behind; wasps and hornets do not. To remove a stinger, scrape across it with the edge of a credit card, butter knife, or fingernail. Don’t use tweezers, because squeezing the stinger can compress the venom sac and push more venom into your skin.
Once the stinger is out (or if there wasn’t one), wash the area with soap and water. Apply a cold pack or a cloth-wrapped bag of ice for 10 to 15 minutes at a time. This reduces swelling and numbs the pain. Keep the sting site elevated if it’s on an arm or leg.
Managing Pain, Swelling, and Itch
Pain from a mild sting typically fades within a few hours. Swelling, redness, and itching can linger for two to three days, and in some cases up to seven to ten days before the skin fully clears. That timeline is normal and doesn’t mean something is wrong.
Over-the-counter pain relievers like ibuprofen or acetaminophen help with soreness. For itching and swelling, a hydrocortisone cream applied to the sting site two or three times a day is effective. An oral antihistamine can also take the edge off itching and reduce mild swelling. Resist the urge to scratch. Broken skin invites infection and slows healing.
How to Tell a Normal Reaction From Infection
A sting site that’s red, swollen, and itchy is a normal inflammatory reaction, not an infection. Large local reactions, where redness and firmness spread several inches around the sting, can look alarming but are still a typical immune response. The hallmarks of a normal reaction are a visible puncture point at the center, itch as the dominant sensation, and redness that isn’t particularly painful to touch.
Infection (cellulitis) looks different. Watch for increasing pain rather than itch over the following days, spreading redness with warm skin, streaks extending outward from the site, pus or cloudy drainage, or fever. These signs usually appear two to three days after the sting. If you see them, you likely need antibiotics.
Recognizing a Severe Allergic Reaction
Anaphylaxis is the most dangerous response to a sting, and it develops fast, usually within minutes. The warning signs go well beyond the sting site:
- Breathing trouble: throat tightness, swollen tongue, wheezing
- Skin changes far from the sting: widespread hives, flushing, or pale skin
- Circulation problems: a weak and rapid pulse, dizziness, fainting
- Gastrointestinal symptoms: nausea, vomiting, diarrhea
Anaphylaxis requires an epinephrine injection. If you carry an epinephrine auto-injector, use it immediately, then go to the emergency room. Even if symptoms improve after the injection, they can return without another exposure, so emergency observation is still necessary. If you don’t have an auto-injector, call emergency services right away.
Jellyfish Stings Need a Different Approach
Jellyfish stings work through tiny venom-loaded capsules (nematocysts) embedded in the tentacle fragments left on your skin. The goal is to keep those capsules from firing more venom while you remove them.
First, rinse the area with salt water. Salt water is safe and won’t trigger additional venom release. Do not rinse with fresh water or rub the area with a towel, both of which can cause unfired capsules to discharge. Carefully pick off any visible tentacle pieces with a stick, shell, or gloved hand.
For pain relief, hot water immersion is the most supported treatment. Submerge the affected area in water between 106 and 113°F (about as hot as a comfortable bath, not scalding) for 20 minutes or until the pain eases. If hot water isn’t available, a chemical heat pack applied over a cloth works as a backup. Vinegar, long considered a go-to remedy, is no longer recommended for most jellyfish stings encountered in U.S. coastal waters. Baking soda is also no longer recommended.
Scorpion Stings: When to Watch and Wait
The vast majority of scorpion stings can be managed at home with ice, ibuprofen or acetaminophen, and wound care. Most cause only local pain and some numbness around the sting site. Clean the area, apply a cold compress, and take a pain reliever.
The key is monitoring over the next four to six hours for symptoms that spread beyond the sting site. Signs that a scorpion sting is escalating include tingling or numbness in areas away from where you were stung, muscle twitching, difficulty swallowing, blurred vision, uncontrolled eye movements, excessive drooling, or agitation. These neurological symptoms are associated with bark scorpions (found primarily in the southwestern U.S. and Mexico) and require emergency treatment. Young children and older adults are at higher risk for severe reactions.
Home Remedies: What Works and What Doesn’t
You’ll find plenty of advice about baking soda pastes, toothpaste, mud, and other home remedies. The theory behind baking soda is that its alkaline nature neutralizes acidic bee venom. In practice, this neutralization effect on venom already injected under the skin is minimal. And for wasp stings, baking soda doesn’t even have a theoretical basis, since wasp venom is already alkaline. It won’t hurt you, but cold compresses and over-the-counter medications are more reliable.
What consistently works across sting types is cold therapy (reducing blood flow and numbing nerve endings), elevation (limiting swelling through gravity), and keeping the area clean. These aren’t glamorous, but they’re the foundation of effective sting care. Save the baking soda for baking.
