Deadly Asian Hornets Invade Northern Ireland, Threatening Bees and Biodiversity

In a concerning development, the invasive Asian hornet has been confirmed in Northern Ireland. The Northern Ireland Environment Agency (NIEA) reported the first sighting of the species in Dundonald on October 17, 2025. Further sightings were confirmed two days later, and by October 21, a nest had been located and removed from the same area.

Environment Minister Andrew Muir has urged the public to remain vigilant, as there could be more Asian hornets in the region. While the hornets pose no greater threat to humans than native hornets, they are a significant concern for beekeepers and environmentalists. The Asian hornet is a voracious predator, capable of consuming up to 50 honey bees per day, and can have nests with up to 8,000 individual hornets or grubs.
