The Asian Hornet (Vespa velutina) is an invasive non-native species from Asia. If you find one you must report it (see below). It arrived in France in 2004 and has spread rapidly through continental European countries and is threatening to take hold in the UK.
Early sightings and accurate identification are essential to contain their spread in the UK, which can be as much as 60km per annum. For every nest not destroyed, it is likely that between 4-6 new nests (creating c.6,000 hornets each) will be established within a 1 kilometre radius.
Nests can be high in trees and difficult to spot until leaf fall in the autumn but also have been found at lower levels in hedges and buildings. DO NOT APPROACH these nests without adequate protection as Asian Hornets are very defensive near their home.

Reporting the Asian Hornet
Westerham beekeeper, Tracy Johnstone, a pest controller by trade, is our first point of contact:
Try to take a picture for identification purposes (if safe to do so) and a good note of location
Asian Hornet (Vespa velutina) versus our native European Hornet (Vespa crabo)
Our native hornet is slightly larger, with more yellow on its abdomen, a light brown face and light brown (NOT YELLOW) legs. It is relatively harmless to our honeybees and a beneficial pollinator.
