What Sting Hurts the Most
The bullet ant sting is widely considered the most painful insect sting. Its venom causes intense, burning pain that can last for hours. Pain is measured using the Schmidt Sting Pain Index, where the bullet ant ranks at the top for duration and intensity.
Other highly painful stings come from wasps, hornets, and certain tropical ants. Their venom contains chemicals that trigger strong nerve signals and inflammation. In humans, pain levels depend on venom chemistry, sting location, and individual sensitivity.
For most people, a single sting causes sharp pain, redness, and swelling that fades within hours. Severe allergic reactions can lead to difficulty breathing, swelling of the face or throat, and dizziness. These symptoms require immediate medical care and may indicate anaphylaxis.
To reduce pain, wash the area, remove the stinger if present, apply a cold compress, and take an over-the-counter pain reliever. People with known allergies should carry an epinephrine auto-injector and seek emergency help after any sting.
