It happens in a flash. You’re reaching for a soda at a cookout or pulling a weed in the garden, and suddenly, it feels like a hot needle just drove into your skin. Honestly, getting hit by a yellow jacket is a uniquely miserable experience. Unlike honeybees, which die after one shot, these little guys are built like tiny, aggressive fighter jets. They don't lose their stinger, so they can tag you over and over if you don't move fast enough.
Most people want to know the same thing immediately: how long does yellow jacket sting last?

The short answer is that the "holy cow, that hurts" phase usually lasts about one to two hours. But if you’re looking at the total time for the swelling, redness, and that maddening itch to disappear, you’re usually looking at a window of three to seven days.
The Timeline of a Typical Sting
When a yellow jacket stings you, it’s not just a mechanical poke. It’s a chemical injection. They pump in a complex cocktail of proteins and enzymes that basically tell your nerves to scream "fire."
The first 60 minutes are the hardest. You'll feel an intense, sharp burning sensation. The area will turn red almost immediately, and a small white welt (called a wheal) usually pops up right where the stinger went in.
After two hours, the sharp "stinging" usually fades into a dull, throbbing ache. This is when the itching starts. Pro tip: don't scratch it. I know, it’s easier said than done. But scratching can actually push the venom deeper or, worse, break the skin and lead to a secondary infection.
At the 24 to 48-hour mark, you'll likely see the peak of the swelling. It’s weird, but stings often look worse on day two than they do on day one. If you got hit on the hand, your whole hand might look like a puffy latex glove.

Days 3 through 7 are the "fading" phase. The redness starts to shrink, the swelling goes down, and you’re just left with a small, slightly itchy spot that eventually vanishes.
What if it lasts longer?
If you're still seeing redness getting larger after three days, or if you develop a fever, that’s a red flag. Dr. Afaneh at Scripps Health notes that while infections are actually pretty rare with stings, they do happen—especially if you’ve been scratching with dirty fingernails.
Why Some Stings Feel Like a Week-Long Event
There is a thing called a "Large Local Reaction." About 10% of people get these. It’s not a full-blown life-threatening allergy, but it’s definitely more than a "normal" reaction.
If you have a large local reaction, the swelling doesn't just stay around the hole. If you’re stung on the ankle, your entire calf might swell up. It looks terrifying. It feels tight and hot. For these lucky folks, the symptoms can hang around for a full 10 days.

Real Ways to Make it Stop Hurting Sooner
Forget the old wives' tales about rubbing a penny on it or using mud. Mud is just a great way to get a staph infection.
Stick to what actually works to break down the proteins in the venom:
- The "Scrape" Move: Yellow jackets don't usually leave a stinger, but if they got crushed mid-sting, a fragment might be there. Use a credit card to scrape it out. Don't use tweezers; you'll just squeeze the venom sac like a tiny tube of toothpaste and inject more "ouch" into your arm.
- Baking Soda Paste: This is a classic for a reason. Mix a little water with baking soda to make a thick paste. It’s alkaline, which helps neutralize the acidic components of the venom. Leave it on for 15-20 minutes.
- Meat Tenderizer: This sounds crazy, but it works. Most meat tenderizers contain an enzyme called papain (from papaya). It’s designed to break down protein in steak, and it does the same to the protein-based venom in your skin.
- The Cold Factor: Ice is your best friend for the first 24 hours. 10 minutes on, 10 minutes off. It constricts the blood vessels so the venom doesn't spread as fast.
- Antihistamines: Benadryl or Claritin won't stop the initial pain, but they are lifesavers for the "I want to claw my skin off" itching that happens on day two.
When to Actually Panic (The 2-Hour Rule)
We need to talk about anaphylaxis because yellow jackets are actually responsible for more allergic reactions in the U.S. than almost any other insect.
A severe allergic reaction almost always starts within the first 2 hours—and usually within the first 20 minutes. If you’ve been stung and you feel fine an hour later, you’re likely in the clear for the scary stuff.
Seek emergency help immediately if you notice:
- Difficulty breathing or a "tight" throat.
- Hives breaking out on parts of your body where you weren't stung.
- Feeling dizzy or like you’re going to faint.
- Swelling of the tongue or lips.
Interestingly, if you’ve had a bad reaction once, you have about a 60% chance of having another one (or a worse one) next time. This is why allergists often suggest venom immunotherapy—basically "allergy shots" for stings—which can be 95% effective at preventing future reactions.
The "Dirty Stinger" Myth
You might hear people say yellow jacket stings last longer because they eat trash. It’s true that yellow jackets are scavengers—they love "people food," rotting fruit, and soda cans. Because of this, they can carry more bacteria than a honeybee that spends its day on clean clover.
If your sting starts oozing pus, or if you see red streaks leading away from the site, that’s not the venom anymore. That’s a bacterial infection. You’ll need a doctor and probably some antibiotics for that.
Actionable Steps for Recovery
If you just got stung, here is your play-by-play:
- Minute 1: Get away from the area. Yellow jackets mark you with a pheromone that tells their buddies to attack the same spot.
- Minute 5: Wash the area with soap and cool water. This removes the "attack" pheromone and any surface bacteria.
- Hour 1: Apply that baking soda paste or a cold compress. If you have an antihistamine like Benadryl, take it now to get ahead of the swelling.
- Day 2: Keep the limb elevated if possible. If you were stung on the hand, don't let it hang down by your side; keep it propped up on a pillow.
- Day 3: Switch to hydrocortisone cream if the itching is driving you nuts.
Basically, you're going to be okay. It feels like the end of the world for the first hour, but your body is pretty good at cleaning up the mess. Just keep it clean, keep it cold, and keep your hands off the itch.
