Asian Hornet Alert: Northern Ireland Fights Invasive Species
26 Apr
Summary
- An Asian hornet nest was discovered in County Down, marking the most northerly find yet.
- 34 traps are deployed within a 5km radius, and 20,000 households received informative leaflets.
- Climate change is aiding the Asian hornet's northward expansion into new territories.
Northern Ireland is actively combating the Asian hornet, an invasive species whose nest was recently found in County Down, marking the most northerly discovery in its range. This species poses a significant threat to pollinators essential for the food system.
The Northern Ireland Environment Agency (NIEA) is employing a strategy focused on public reporting via the Asian Hornet Watch app rather than direct extermination. Thirty-four specialized traps have been set up within a five-kilometer radius of the discovery site, and extensive public outreach includes information leaflets delivered to 20,000 local households.
Experts believe climate change is contributing to the Asian hornet establishing itself further north than previously observed. The NIEA team conducted a track and trace operation after the nest's discovery in October, which was subsequently destroyed. However, uncertainty remains regarding whether any queen hornets developed and could have survived the winter.
Monitoring efforts are now concentrated on identifying and removing any emerging queen hornets to prevent new nest establishment. The public is urged to report sightings through the app, with experts emphasizing the importance of not attempting to trap insects themselves to avoid harming native species.
