I have been to the apiary and met Simon, I assure you he has done everything possible to protect his colonies. His apiary have more traps set than you can imagine and he has trapped out areas beyond his apiary to determine the flight direction and draw them away. His apiary is inundated with hornets, he has trapped up to 40 in a single day. They are absolutely hammering his hives, it is relentless. The apiary is located 200m from the top of the cliff system which in itself is 500m from the sea. The area is almost completely inaccessable, it has just one footpath through it. There are multiple Asian Hornet nests in the area, you can easily tell this by the number of unique flight trajectories but despite a massive effort by the NBU on the ground and others the nests have not been found. It is most likely that these were from Queens that overwintered in the area rather than blown in or hitchhikers. Further nest finds in Kent have largely been from this location, along the North Downs and up to Rochester, Gravesend and London, and the the west of the line. In 3 or 4 weeks those nests will be releasing Queens, in France they spread at 80km per year.
