Bee Sting or Wasp Sting? The Difference Matters

At a glance
When a bee stings, it loses its stinger along with the attached venom sac. The stinger stays in the skin and keeps releasing venom — it has to be scraped out sideways, never squeezed. Wasps keep their smooth stinger and can sting repeatedly. Apart from that, the same first aid applies: cool the site and watch the reaction.

Whether you were stung by a bee or a wasp makes a decisive difference to the correct first aid. This article explains how to tell the two stings apart and what to do in each case. It is not a substitute for medical advice.
The key difference: the stinger
A bee’s stinger has fine barbs. As it stings, the stinger anchors itself in the skin, and as the bee flies away it tears off from the bee together with the venom sac and parts of the abdomen. The venom sac then continues to release venom for as long as it remains in the wound. A bee that has stung once dies as a result. A wasp’s stinger, by contrast, is smooth and does not stay lodged in the skin — which is why a wasp can sting several times.
Removing the stinger correctly
If the stinger and venom sac are still visibly lodged in the skin after a bee sting, scrape them out sideways with a bank card, the blunt back of a knife or your fingernail. Never use tweezers and never squeeze with your fingers: this presses additional venom from the venom sac into the wound, which can intensify the reaction. After a wasp sting this step does not apply, as no stinger is left behind.
Venom and its effects
Bee venom contains, among other things, the active compounds melittin, apamin and phospholipase A2, which are responsible for pain, swelling and, in some people, allergic sensitisation. Wasp venom has a different chemical composition but can likewise trigger allergies. People with a diagnosed insect venom allergy should know exactly which venom they are allergic to, as treatment and desensitisation depend on it; you can read more in our guide «Insektengift-Allergie erkennen».
Otherwise the first aid is the same
Apart from removing the stinger, the same approach applies to both insects: cool the site, watch the reaction and, at any warning sign such as difficulty breathing, swelling in the throat or hives across the body, call the emergency number 144 (the Swiss ambulance service) immediately. Detailed immediate measures can be found in our pillar guide «Wespenstich — was tun?» and in the article «Wespe oder Biene?» on how to tell the two insects apart by sight.
Frequently asked questions
Why does only a bee leave its stinger behind?
A bee's stinger has small barbs and is connected to the venom sac. As the bee flies away, the stinger tears off together with part of the bee's body and remains in the skin. The smoother wasp stinger has no such barbs and is not torn off.
How do I remove a bee stinger correctly?
Scrape it out sideways with a bank card or your fingernail. Avoid tweezers and do not squeeze it, as this can force additional venom from the venom sac into the wound.
Is a bee sting more painful than a wasp sting?
Pain perception varies from person to person. The two venoms contain different active compounds, but both can trigger a comparable local reaction with pain, redness and swelling.
