But you didnt wait till the cold season, did you? I guess everything succeded without turning into disaster.
We performed it a very safe way. Read about few methods but they are risky! What makes things worse, they often choose to build a nest st such a spot that is hardly to get to. I had to build sort of pedestal, a raised platform to stand at, and knocked the nest down with a shovel into a packet. And my wife held the bag open and close to the nest using two long boards. In our case, there was no risk cause the hornets were hibernating - but if it had been warm summer temperatures... the success would not have been so successful, knocking down the nest was not a simple 1-second click, alas, took me 2 minutes.
