The pumpkin-sized hornet's nest was at the top of a 17m conifer found in Tetbury, Gloucestershire.

Asian hornets are in invasive species of hornet that pose no significant risk to human health although, they do kill honey bees. They were first confirmed in the UK last month.

The one inch long species of hornet was discovered for the first time in Channel Islands Jersey and Alderney this summer, although experts are still unsure exactly how they arrived here. It's possible that they've been accidentally imported with plants and timber. Our mainland European neighbours have been dealing with these new pests for over ten years now. However, this will be the first time UK pest controllers will have to deal with this species.

The Bees, Wasps, and Ants Recording Society commented:

"Following the recent discovery of two Asian Hornet workers near Tetbury in Gloucestershire, bee inspectors from the National Bee Unit have visited over 100 sites in the local area.

"Asian Hornets were found at six locations within 500m of the original sighting."

The Animal & Plant Health Agency commented:

"Inspectors from the National Bee Unit, part of the APHA, are continuing to monitor the area for Asian hornets alongside local beekeepers. However, to date, no live hornets have been seen since the nest was removed."
