Asian Hornet Identification and Control

The Asian Hornet (Vespa velutina), also known as the yellow-legged hornet, is an invasive species originally from East Asia. In the UK, the main concern is not day-to-day nuisance — it’s the impact on native pollinators, particularly honey bees, which support ecosystems and food production.

Why Asian Hornets Are a Concern

• Threat to bees and pollinators: Asian hornets can hunt honey bees and other insects, reducing pollination and ecosystem health.
• Knock-on environmental impact: Fewer pollinators can affect plant reproduction, biodiversity, and crop yields.
• Nest defence: They can defend nests if disturbed, increasing sting risk in the immediate area.

How to Identify an Asian Hornet

• Body: Dark brown/black overall with an orange band on the fourth segment of the abdomen.
• Legs: Distinctive yellow tips (hence “yellow-legged hornet”).
• Compared to a European hornet: European hornets are generally larger and have bold yellow striping and a more reddish-brown thorax.

What To Do If You See One

Where They Build Nests

Asian hornets often build large, egg-shaped paper nests high in trees, under rooflines, or in sheltered outdoor areas. Occasionally, nests can also appear in sheds, garages, or loft spaces.

Reducing Attraction Around Your Property

• Avoid leaving sugary foods/drinks uncovered outdoors (especially in summer).
• Seal rubbish bins tightly and clear spillages quickly.
• Consider fitting fine mesh screens on doors/windows to reduce indoor entry.
• Check sheltered corners, eaves, and outbuildings for early nest activity.

Are They Dangerous To Humans?

Asian hornets are generally not aggressive towards humans, but they will defend their nest if disturbed and can sting multiple times. Stings are painful and, in rare cases, can trigger allergic reactions — especially if someone is stung repeatedly or has a known sensitivity.
