The spread of the Asian hornet (Vespa velutina), also known as the yellow-legged hornet, continues to be a growing concern across the UK. While it has not yet become fully established, recent data shows a clear increase in sightings and nest discoveries — raising important questions for homeowners, businesses, and beekeepers in Cornwall.
At D Cornish Pest Control, we’re keeping a close eye on developments so you know exactly what to look out for and how to respond.
📈 Asian Hornet Sightings in the UK: The Latest
The most recent data highlights a noticeable rise in activity:
- 2025 saw record numbers, with over 500 sightings reported
- More than 160 nests were identified and destroyed
- Sightings are no longer limited to the south-east and are gradually spreading
So far in 2026, confirmed sightings remain relatively low — but this is typical for early in the season. Numbers tend to increase significantly through late summer and early autumn.
🧭 Are Asian Hornets Established in the UK?
At present, the Asian hornet is not fully established in the UK.
However, the situation is changing:
- Hornets are arriving more frequently from mainland Europe
- There is evidence that some queens are surviving UK winters
- The geographical spread is slowly widening
This means the UK is approaching a critical tipping point, where permanent populations could become established if not carefully controlled.
📍 What About Cornwall?
For Cornwall, the risk is real — but currently lower than in other parts of the UK.
Because of our coastal location, Asian hornets can:
- Arrive via wind-assisted migration from France
- Potentially be transported through freight and vehicles
Although confirmed cases locally remain limited, vigilance is key — particularly during the warmer months.
⚠️ Why Asian Hornets Are a Problem
Asian hornets pose a serious threat to:
🐝 Honey Bees and Pollinators
They are highly efficient predators, capable of decimating bee colonies and impacting biodiversity.
🌿 Local Ecosystems
A single nest can consume thousands of insects, disrupting the natural balance.
🏡 Homes and Businesses
While they are not typically aggressive unless disturbed, nests near properties can pose a safety risk.
🔍 How to Identify an Asian Hornet
It’s important not to confuse them with native hornets.
Key features include:
- Mostly dark body (almost black)
- Bright yellow/orange band on the abdomen
- Distinctive yellow legs (hence “yellow-legged hornet”)
- Slightly smaller than the native European hornet
If you’re unsure, it’s always best to seek professional advice rather than approach the insect yourself.
🚫 What to Do If You Spot One
If you think you’ve seen an Asian hornet:
- Do not attempt to approach or destroy it
- Take a photo if safe to do so
- Report it via the official UK reporting system or contact a professional
Early reporting is critical — it allows authorities to track and destroy nests before they spread.
