The House Detective: by Barry Stone, Certified Home Inspector
Dear Barry: I have an intermittent buzzing sound in my bathroom wall, and it’s driving me crazy. It only buzzes between sunset and 11pm every evening and is very noisy. I have tried turning off the electrical power at the main, turning off individual circuit breakers, and shutting off the water main, but the noise continues each evening. Sometimes it stops for five or ten seconds and then starts up again. A contractor suggested opening the wall to see what’s going on, but we just remodeled the bathroom, and we hate to tear things up. What do you advise? Paul
Dear Paul: Now that you have eliminated electrical and plumbing conditions as possible causes, the most likely suspect is a bee hive or wasp nest. Bees usually return to their hive around sunset, which is when you begin to hear the buzzing in your wall, and later in the evening they usually settle down for the night. Check your phone directory or the internet for local companies that specialize in bee hive removal. Unfortunately, you may have to cut open the wall of your newly remodeled bathroom.
