Brighton and Lewes are very much aware that as we are close to ports both in Newhaven and Shoreham we could be next to have a hornet in our area.
There have been several sightings of Asian Hornets around the country and already two nests have been destroyed. You can see the map of reported sightings here.

It would be useful if every beekeeper makes and observes a monitoring trap and observes what gets caught. Details NBU monitoring trap here.
