Jersey Sees 50% Rise in Asian Hornet Nests, Sting Risks Increase

Jersey is experiencing a growing public safety concern due to a 50% increase in Asian hornet nests in 2026 compared to last year. Over 800 nests have been found so far, with projections reaching up to 1,000 by year-end, raising the risk of dangerous stings.

Environment Minister Mary Le Hegarat noted 50 sting cases in 2025, mostly from accidental nest disturbances. The invasive Asian hornet threatens native pollinators such as honey bees. Although not established on mainland UK, over 120 sightings have been recorded since 2016.
