A bee sting is a puncture wound delivered by a honey bee’s barbed stinger, which injects venom into the skin and triggers an inflammatory response. For most people, it causes temporary pain, redness, and swelling that resolves within a few days. In a small percentage of people, it can cause a severe, life-threatening allergic reaction.
How a Bee Stinger Works
A honey bee’s stinger is more sophisticated than a simple needle. The stinger has tiny barbs arranged in a spiral pattern, and as it enters skin, it actually rotates in a clockwise, corkscrew-like motion. Those barbs provide one-way traction, pulling the stinger deeper into flesh with each turn. This is also why you can’t easily pull it back out: the barbs anchor it in place.
When a honey bee stings you, the entire stinger apparatus tears away from the bee’s body, killing it. The detached stinger keeps pumping venom on its own, emptying its venom sac within about 30 seconds. This is a key distinction from wasps, hornets, and yellow jackets, which have smooth stingers, can pull them out, and sting you multiple times. If you see a stinger left behind in your skin, you were stung by a honey bee.
What’s in Bee Venom
Bee venom is a cocktail of proteins and peptides, but two components do most of the damage. The main one, called melittin, has a lytic effect, meaning it breaks open cells on contact. The second major component is an enzyme that triggers inflammation and pain signaling. Together, these substances punch holes in cell membranes and set off a cascade of inflammatory signals, including the release of hydrogen peroxide and molecules that cause redness, heat, and swelling at the sting site.
What a Normal Sting Feels Like
A typical bee sting causes immediate, sharp pain at the site, followed by a red welt with a small white spot where the stinger entered. The area becomes sore, swollen, and possibly itchy. These symptoms usually peak within the first few hours and fade over a few days.
Some people develop what’s called a large local reaction. The swelling grows over two to three days, reaching about four inches in diameter or more, and can spread across a joint. This looks alarming but isn’t the same as an allergic emergency. A large local reaction can take five to ten days to fully heal, with symptoms lasting up to a week.
Signs of a Dangerous Allergic Reaction
Anaphylaxis is the serious risk with bee stings, and it can be life-threatening. It typically develops within minutes, not days. The warning signs go beyond the sting site and affect your whole body:
- Skin: widespread rash or hives, intense itching far from the sting
- Breathing: trouble breathing, tightness in the chest, wheezing
- Throat and mouth: swollen tongue, difficulty swallowing
- Circulation: dizziness, rapid pulse, drop in blood pressure, loss of consciousness
Even one or two of these symptoms after a bee sting warrants calling 911. If you carry an epinephrine auto-injector, use it immediately, then call for emergency help. Epinephrine first, phone call second.
How to Remove the Stinger
You’ve probably heard that you should scrape the stinger out with a credit card and never squeeze it. The reasoning sounds logical: pinching the venom sac might push more venom in. But research on this point tells a more nuanced story. Studies have found no statistically significant difference in reaction size between scraping and pinching the stinger out. What actually matters is speed. The venom sac empties within about 30 seconds, so every moment counts more than your technique.
Scraping with a fingernail or flicking the stinger away is still the recommended approach from groups like the American Academy of Dermatology, largely because it’s fast and doesn’t require tools. But if your instinct is to grab it with your fingers, that’s better than spending 20 seconds looking for a credit card. Get it out however you can, as quickly as you can.
Treating a Bee Sting at Home
Once the stinger is out, wash the area with soap and water. Apply a cold pack wrapped in cloth for 10 to 15 minutes to reduce swelling and numb the pain. For itching and inflammation, hydrocortisone cream or calamine lotion applied up to four times a day can help until symptoms resolve. An over-the-counter antihistamine can also ease itching and mild swelling.
Try not to scratch the sting site. Broken skin from scratching increases the risk of a secondary bacterial infection, which can develop into cellulitis (a spreading skin infection marked by expanding redness, warmth, and tenderness that gets worse instead of better over time). If the redness keeps growing after a few days, feels increasingly warm, or you develop a fever, that points to infection rather than a normal sting reaction.
Multiple Stings
A single bee sting delivers a small dose of venom, but multiple stings at once can cause a toxic reaction even in someone who isn’t allergic. When the total venom load is high enough, it can cause nausea, vomiting, headache, fever, and in extreme cases, organ damage. This is a concern with swarm attacks or disturbed hives rather than a single bee encounter. Children and smaller adults are more vulnerable to toxic reactions from fewer stings because of their lower body weight.
Why Some People React More Severely Over Time
Your reaction to bee stings can change. Someone who had only mild swelling from a first sting may develop a large local reaction or even anaphylaxis from a later sting. This happens because the immune system can become sensitized to venom proteins, producing specific antibodies that trigger a larger response on subsequent exposure. If your reactions to stings have been getting progressively worse, allergy testing can determine your risk level. For people with confirmed venom allergy, a treatment called venom immunotherapy gradually desensitizes the immune system over several years and is highly effective at preventing future anaphylaxis.
