Numbers of yellow-legged Asian hornets have been growing steadily here over recent years, until last year when there was a huge increase in sightings, which led to a number of nests being destroyed in Kent and along the south coast. Incursions have also been reported in a number of other locations, including as far north as Scotland. More yellow-legged Asian hornets were spotted in 2023 than in the previous six years combined and there have already been a number of confirmed sightings this year.
The Asian hornet is a voracious predator of honeybees, with one hornet capable of consuming dozens of bees in a single day. This has grave implications for other species that rely on our pollinators, and the security of our food chain.
This is also now an issue of public health concern. While one hornet is unlikely to cause a problem, these insects are aggressively defensive of their nests, which can be built at the tops of trees, low to the ground in hedgerows and brambles, and even underground in some cases. Any disturbances by unsuspecting individuals could have dangerous consequences. This has implications across all of society, but is of particular concern for those who take part in outdoor activities, such as geocaching.
Geocachers searching for hidden items could be placed in direct contact with Asian hornets, and if they disturb a nest it could lead to a very serious situation.
We’re asking everyone to download the Asian Hornet Watch app and log any suspected sightings, so that nearby nests can then be traced and disposed of by official authorities.
Geocachers are perfectly placed to be the eyes on the ground on this issue, and we can really help in keeping a watch for these invasive insects.
