What to do in case of an Asian hornet sting?

Return to the list of articles

An Asian hornet sting can be alarming and very painful. In most cases, it causes a harmless, localized reaction, but some situations require particular attention and prompt medical attention. Knowing how to react to an Asian hornet sting can help minimize pain, prevent complications, and recognize signs of a serious condition.

This guide explains the right reflexes to adopt immediately, the normal symptoms, the warning signs to watch for, and the situations in which it is essential to consult a healthcare professional.

Recognizing an Asian hornet sting

An Asian hornet sting typically causes sharp, immediate pain, often more intense than a wasp sting. The affected area quickly becomes red, hot, and swollen. Local swelling may occur, accompanied by itching or a burning sensation. In some people, the pain can persist for several hours or even several days.

It is important to note that the Asian hornet, unlike the bee, does not lose its stinger after stinging. It can therefore sting repeatedly, which explains why some victims experience several stings in quick succession.

The right reflexes immediately after a sting

If stung, the first thing to do is calmly move away from the area to avoid further attacks, especially if a nest is nearby. It is then advisable to clean the affected area with soap and water to minimize the risk of infection.

Applying cold, using an ice pack or a cool, damp cloth, can reduce inflammation and relieve pain. Slightly elevating the affected limb can also help limit swelling. In cases of severe itching, a topical antihistamine or soothing cream can be used, following the instructions on the package insert or the advice of a healthcare professional.

Normal symptoms or a worrying reaction: how to tell the difference

In most cases, the reactions remain localized and mild. Redness, moderate swelling, localized pain, and a feeling of heat are common and normal reactions after an Asian hornet sting. These symptoms usually disappear within a few hours to a few days.

However, certain signs should raise concern. An allergic reaction can manifest as significant swelling of the face or throat, difficulty breathing, a feeling of faintness, dizziness, nausea, or a widespread skin rash. These symptoms may indicate an anaphylactic reaction, which is a medical emergency.

When should you seek emergency medical attention?

It is essential to consult a healthcare professional or call emergency services promptly in several situations. This is the case when the sting is located in the mouth, throat, or near the eyes, as swelling can lead to respiratory or visual complications. Urgent action is also necessary in the event of multiple stings, particularly in children, the elderly, or those with underlying health conditions.

Any appearance of severe allergic symptoms, such as difficulty breathing or loss of consciousness, requires immediate medical attention. People known to be allergic to insect stings should use their prescribed emergency treatment and seek immediate medical attention.

Preventing risks after a sting

After a sting, it is advisable to monitor the affected area for several hours. If the pain intensifies, if the swelling becomes significant, or if signs of infection appear, medical consultation is recommended.

To minimize future risks, it is important to avoid approaching Asian hornet nests and not to attempt to destroy them yourself. If you find a nest near your home or a frequently visited area, reporting it to the local authorities or a specialist remains the safest course of action.
