Jersey Battles Rising Asian Hornet Threat

Jersey is confronting an escalating threat from Asian hornets, which are increasingly impacting public safety. The number of identified nests has surged by 50% as of early October 2026, with over 800 nests found and the majority destroyed. This invasive species poses a significant risk to native insects and pollinators.

Officials anticipate a further doubling of nests in the coming year, with forecasts suggesting up to 2,000 nests. This rise heightens the likelihood of serious sting incidents, including those that are potentially life-threatening. Most incidents stem from accidental nest disturbances rather than encounters with individual hornets.

Asian hornet stings typically cause localized reactions but can trigger fatal allergic responses in susceptible individuals. In 2025 alone, 50 sting incidents were reported on Jersey, including one confirmed anaphylactic reaction and several hospital visits.

The growing challenge requires a coordinated cross-government response to manage this biological security and public safety issue. In the UK, while not yet established, over 120 Asian hornet sightings have been confirmed up to July 2024, with nests located and destroyed.
