British Pest Control Association supports calls to report Yellow-legged (Asian) Hornet sightings
Experts at the British Pest Control Association (BPCA) have backed calls for Brits to report sightings of the aggressive Yellow-legged Hornets.
BPCA is shining a spotlight on the hornets this week (May 12 to 18) as part of Invasive Species Week, as work continues to prevent them becoming established in the UK.
BPCA technical manager, Nial Gallagher, said: “These invaders are a predator of honeybees and could disrupt our native eco-systems and impact crop production.
“Any sightings should be reported to the Non-Native Species Secretariat and we’d advise getting help from a member of the National Bee Unit or a member of the British Beekeepers Association.
“If you discover a European hornet nest, we always recommend seeking help from a BPCA member, especially if it is indoors, or in a difficult place to access.
“Anyone tempted to try a DIY treatment must be certain any product they choose is licensed for use in the UK and must always strictly adhere to the instructions on the label.”
Some recent media reports have suggested that pest controllers may be able to help with yellow-legged Asian hornets
Currently the only organisation with authority to track & eradicate is the National Bee Unit.

How to spot and report a Yellow-legged (Asian) Hornet
There are three ways to report a possible sighting of the Yellow-legged (Asian) Hornet:
Mr Gallagher added: “Since 2016 a number of sightings have been recorded in the UK, and anyone who thinks they’ve spotted a Yellow-legged hornet should report it as soon as possible.
RECOMMENDED READING:
“The Yellow-legged hornet is smaller than our native species. It has an orange head, and its entire body is almost entirely dark.
“The abdomen has fine yellow stripes and a yellow or orange segment near the base. Their legs are dark and have yellow tips, where our native hornet has entirely dark legs.
“Yellow-legged hornets may sting, so it’s important not to disturb an active nest and to seek help.”
