Invasive Asian hornet populations are expected to soar across the UK due to unusually hot weather, with 2026 predicted to be one of the hottest years on record. Experts warn that the focus has shifted from eradicating the hornets to long-term management, as sightings are now occurring much further inland and eradication may no longer be possible.
Growing Threat to British Wildlife
These hornets pose a significant threat to British honeybees, which make up approximately a third of their diet, alongside other insects such as moths and flies. Last year recorded 544 Asian hornet sightings and 161 confirmed nests, more than double the previous annual peak, with a single nest capable of producing around 350 queens.
Public Urged to Stay Vigilant
The public is urged to remain vigilant, report any sightings quickly via the Asian hornet app, and never attempt to approach or remove nests themselves due to the hornets' aggressive nature when disturbed.
In full, the heatwave could fuel an invasion of Asian hornets in the UK, prompting concerns for honeybee populations and the broader ecosystem. Authorities are advising immediate reporting to help track and manage the spread.
