That video makes me feel like an amazing wuss for being afraid of UK wasps (which are maybe 2cm in length), which if they sting you it just stings (they're just aggressive bastards and I got mullered by a wasp when I was a kid). My brother got stung by some kind of hornet in South America and he said it was like getting punched. One of the locals said to him in response that the next time he hears the sound of a hornet, just run.
I'd file that guy's job under the few that I would under no circumstances try to do myself no matter how 100% approved the gear I used to protect myself was (and someone knowledgeable double-checking that I've worn it correctly)! I think even if I somehow managed to destroy that nest, I'd be driving away with the protective gear on, and some miles away I'd be wondering if I'm safe to remove the gear yet! Every time a hair on my body gets tweaked for the rest of that day I'd be swatting imaginary insects.
What on earth is he going to do with the plastic bag full of nest? I'd be sticking it into some kind of heavy duty yet combustible container and then lighting the bastard up. It would be my kind of luck to think "nest is dead!", go to throw it in the bin and then the real end-of-level boss hornet comes out for revenge for what I did to their family.... after I've taken the protective gear off. It would be like out of the finale of 'Alien' just involving lots of high-pitched screaming and flailing around and no space suit.
