What should I do if I'm stung by an Asian hornet?

Asian or yellow-legged hornets (Vespa velutina) can deliver a very painful sting widely described as being “jabbed with a red-hot needle”.

- Fergus Collins

However, as with our native European hornet (Vespa crabro), they are seldom aggressive and there are very few reports of attacks on humans. If you are unlucky enough to be stung by an Asian hornet, the treatment is similar to that for native wasp stings.

The most important thing is to not panic. Shouting, waving arms and attempting to swat the insect can rile it further and it could sting again, or worse, be inhaled in the confusion - this does happen. A typical sting will usually result in pain and a red swelling, which should recede in a day or so in most cases. There is no 'stinger' left behind as with honey bees. You can wash the affected area in soapy water to remove as much venom as possible. Take an antihistamine if the swelling doesn't subside. If you have an allergic reaction, such as a spreading rash, wheeziness or constriction of the airways, you should seek medical advice immediately.
