Do you hear a 'buzzing' noise?

If you don't like bees, please do not watch this video. It reminds me of a nest I once had in my house, although mine was not of the honey-comb variety; it was a yellow jacket nest. When the windows were closed in the fall, I heard a buzzing noise, like leaves rustling. My exterminator said: 1. I had hundreds of yellow jackets in a nest above my bedroom. 2. Yellow jackets are mean and sting for no reason. 3. If they had made it into the house they most probably would have killed us. YIKES!!!!
