Britain is being alerted to the looming threat of an Asian hornet invasion. These invasive insects, characterized by their predominantly black abdomen and distinctive yellow legs, first made their presence known in the UK back in September 2016 when they were spotted in Tetbury, Gloucestershire.
Since their initial sighting in 2016, there have been a total of 74 confirmed instances of Asian hornets in the UK, with a notable increase in 2023, accounting for 51 of these sightings. Importantly, all 69 nests discovered have been promptly eradicated.
The most recent sightings, as of the time of this publication, were reported in Kent on October 4, renewing concerns about the potential establishment of these invasive hornets in the UK.
Asian hornets primarily prey on insects, with a particular focus on native honey bees, posing a significant threat to bee colonies and other indigenous species within the UK. Their stings can cause allergic reactions in some individuals, and they may become aggressive when they perceive a threat to their nest.
Scientists have raised concerns that climate change is creating favourable conditions for alien species in the UK, with Asian hornets being of particular worry.
Francis Russell, the Asian Hornet Strategy Coordinator for the States of Guernsey, issued a stern warning, emphasizing that the UK must take proactive measures to eradicate Asian hornets to avoid an infestation.
Guernsey, Jersey, and other Channel Islands are currently grappling with their own battles against these invasive insects, underscoring the urgency of the situation.
Russell remarked, “Due to the arrival of hornets each spring, the annual eradication of hornets is considered the only achievable goal. The threats are universal and apply equally across any region in Europe where conditions would allow this insect to successfully colonize.”
He further emphasized that the rate of spread for Asian hornets is alarmingly rapid, at approximately 75 kilometers per year, as documented in other European countries.
In response to this pressing issue, the GB Non-native Species Secretariat (NNSS) has called upon the public to report any Asian hornet sightings. Reporting these sightings promptly can play a crucial role in preventing the establishment of this invasive species in new regions. Vigilance is especially necessary in southern parts of England and Wales, as well as around major ports.
Asian hornets are most active from April to November, with peak activity in August and September. They tend to become inactive over the winter months.
To report an Asian hornet sighting, please visit the NNSS website for further information and guidance.
As authorities and experts monitor the situation closely, public vigilance and reporting will be instrumental in mitigating the potential impact of Asian hornets on the UK’s native species and ecosystems.
Britain is being warned about the threat of a possible Asian hornet invasion as reported sightings reach 51 (at the time of publication) in 2023.
