Asian Hornet Week: identifying a dangerous invader

About Asian Hornet Week

Asian Hornet Week (6-12 September) is an annual initiative to raise awareness of this invasive species which poses a threat to our native insects, honeybees and economy.

The Asian hornet was first spotted in the UK in 2016. Since then, it has spread rapidly, with nests now found in many parts of the country. The hornets are a threat to our native insects, as they prey on bees, wasps, and other insects. They can also cause damage to crops and trees.

Identifying Asian Hornets

Asian hornets are slightly larger than native European honeybees, measuring approximately 2.5-3.0 cm in length. They have a distinctive black and yellow body, with a yellow tip to their abdomen. Additionally, they have a dark brown or black thorax and a distinctive orange or yellow face.

What to do if you see an Asian Hornet

If you see an Asian hornet, it is important to report it to the National Bee Unit. You can do this by calling 03459 335577 or by emailing alertnonnative@ceh.ac.uk. It is important not to try to kill the hornets yourself, as this could put you at risk of being stung.

How to protect yourself from Asian Hornets

There are a number of things you can do to protect yourself from Asian hornets:

• Be aware of the signs of an Asian hornet nest.
• Avoid disturbing Asian hornets.
• Keep your windows and doors closed.
• Wear protective clothing if you are working in an area where Asian hornets are present.
• If you are stung by an Asian hornet, seek medical attention immediately.
