Asian Hornet Nests in Jersey Increase by 50%, Raising Safety Concerns

Jersey faces growing public safety risks from Asian hornets, with officials warning that serious stings and life-threatening allergic reactions may become more frequent. Over 800 Asian hornet nests have been found on the island in 2026, a 50% increase from the same period last year, according to Mary Le Hegarat, Minister for Environment, Agriculture and Fisheries.

The invasive species was first recorded in Jersey in August 2016 and later in Guernsey. Asian hornets prey on insects such as honey bees, butterflies, and beetles, threatening local biodiversity. Their stings can cause serious medical issues, sometimes requiring hospital care.
