About 15 years ago I was up on the roof with my brother in law installing a roof exhaust fan when we were bugged by wasps hanging around and ducking under the tiles. I had noticed that someone in the area must have a nest somewhere because they kept annoying us in the backyard and on the patio. I thought to myself, why don't these people do something about the nest, surely they must know.
Well, we got the Flick man in and he climbed up on the roof. His words were "that has to be one of the largest wasp nests I have seen!"

So the person who "should do something" was me

In the end he took out 4 or 5, 20 litre buckets of nest and dead bodies
