We have Bees...

...in our bedroom, in our apartment in Brooklyn. We have no idea how they are getting in. We slept in the wilderness for 6 nights on vacation, and not one critter bothered us. I took a nap the day we got home, and I got stung by a bee in my bed. I'm wondering if there is a beehive in the tree outside our bedroom window. Or maybe the tenant below us has become a secret bee keeper? Right now it is a mystery.
