Mike Brown spoke at the bee farmers meeting a few weeks ago on his experiences in a village in France where beekeepers (often elderly!) were volunteering to go up very long turntable ladders in the dark to inject sulphurous fumes into Asian hornet nests. Desperate measures!

Here is a clip showing some of the things they are doing elsewhere.

Worth a look, even if you don't follow the language:
