Info from Licensor: "My neighbor had seen a few bees in their house and thought nothing of it. The next morning they woke up and there were at least 3,000 bees in the inside of their kitchen. We entered their home and thousands of bees were buzzing around in the living room, kitchen and the windows. I took the video from the outside looking into to the living room windows as you could see, they were not happy. The owner of the house found that the queen been and her nest was in the chimney. So, a friend of theirs taped off the fireplace inside the house."
