Asian Hornets in the UK – 2025 Updates & Why Malvern Needs to Stay Alert
Introduction
Asian hornets (Vespa velutina nigrithorax) continue to spread across Europe and are being detected more frequently in the UK. In 2025, the number of sightings and nests destroyed reached record levels, prompting urgent warnings from government agencies, scientists, and local organisations. For Malvern and Worcestershire, this is not just a distant issue—it has real consequences for public safety, local biodiversity, and the pollinators that underpin our food systems.
1. Record Sightings in 2025
According to official DEFRA and National Bee Unit data, more Asian hornet nests have been recorded in 2025 than in any previous year since their first UK detection in 2016. The Independent (Aug 2025) reported an 'unprecedented surge' of sightings, with multiple nests destroyed in Kent, Sussex, and Hampshire. The Guardian (April 2025) highlighted concerns from scientists that hornets are now showing signs of overwintering in the UK—an alarming development that raises the risk of permanent establishment.
2. Why This Matters for Worcestershire
Worcestershire, with its mix of rural farmland, orchards, and gardens, is especially vulnerable because Asian hornets prey heavily on honeybees and wild pollinators. Worcestershire Wildlife Trust (2025) has urged the public to be vigilant, noting that misidentification is common with our native European hornet. If the Asian hornet becomes established, beekeepers in Malvern, Upton‑upon‑Severn, Pershore, and surrounding areas could face significant losses.
3. Impact on Pollinators and Local Ecosystems
Asian hornets are apex insect predators. Research published in 2025 shows that hornets target honeybee colonies directly, killing thousands of foragers during late summer and autumn. Southampton University scientists have even identified a 'unique buzz' produced by Asian hornets (Aug 2025), which may offer a new detection method. But until such technology is deployed widely, the best defence remains early public reporting and rapid nest destruction.
4. Weather Patterns and Early Activity
Spring 2025 was one of the warmest on record in southern England. Experts at the Animal and Plant Health Agency (APHA, May 2025) warned that mild winters increase survival of overwintering queens. This explains the sharp rise in spring and early‑summer sightings, with nests maturing earlier and reaching dangerous sizes by August and September.
5. Identification Guide (Asian vs. European Hornets)
• Asian hornet: Dark abdomen with a single orange band, yellow legs, smaller and slimmer than European hornet. Nests often high in trees or in sheds/outbuildings.
• European hornet: Larger, more yellow markings, brown legs, and part of the UK’s native ecosystem.
If in doubt, do not approach—use a telephoto photo from distance and report via the Asian Hornet Watch app.
6. How Many Nests Have Been Destroyed?
As of August 2025, more than 120 Asian hornet nests have been destroyed in the UK since 2016, with dozens already located in 2025 alone (gov.uk official tracking data). Scientists believe this figure underestimates the real population, since many nests go undetected until late in the season or after producing new queens.
7. Public Awareness & Reporting
The National Bee Unit continues to lead eradication efforts, with public reporting playing a vital role. The Guardian (Aug 2025) revealed that the hornet’s distinctive wing‑beat sound may soon be used in AI‑driven acoustic traps, but until then, reporting remains the frontline defence. Residents in Worcestershire are being urged to use the Asian Hornet Watch app or the National Bee Unit website to submit sightings quickly.
8. Malvern Pest Control’s Local Response
At Malvern Pest Control, we are receiving an increasing number of enquiries from worried residents who believe they may have spotted an Asian hornet. We provide safe identification, professional inspections, and can liaise directly with the National Bee Unit where Asian hornet is suspected. For confirmed wasp and native hornet nests, we offer fast, safe treatments across Worcestershire, Herefordshire, and Gloucestershire.
9. Safety Advice for Residents
• Never attempt DIY removal of a suspected Asian hornet nest.
• Keep children and pets away from areas of high hornet activity.
• Report any sightings with photographs via the Asian Hornet Watch app.
• Contact Malvern Pest Control for safe inspection and treatment options.
10. Looking Ahead – Autumn 2025
The risk period peaks in late summer and early autumn, when Asian hornet nests reach their largest size and produce new queens. Rapid action between now and October is crucial to prevent further spread. Worcestershire residents and businesses can play a vital role by staying vigilant and reporting early.
Conclusion
The Asian hornet situation in the UK is escalating in 2025, with record numbers of sightings and nests. For Malvern and Worcestershire, vigilance and quick reporting are essential to protect pollinators, ecosystems, and livelihoods. If you see suspicious hornet activity, act fast: report it, and call Malvern Pest Control for professional support. Together, we can help contain this invasive threat before it becomes permanently established in the UK.
