I had a nest of them in the side of my house this year. This was a first for me and I was not happy with their presence so I killed the nest but I have heard a lot of people say to just let them bee. I'm pretty territorial that way, if it might harm me or my stuff, I'm inclined to eliminate it. I have seen a couple of videos where they tag the hornet with a piece of TP or something and chase it down and I wonder if it's as easy as they make it look or if it actually takes a lot more time and effort and they just edit all that out.
