Funny you mention bees. I have a European Honey Bee hive in the space between my first floor ceiling and my second floor. They're getting in through a poorly designed vent grate on the side of my house. We first noticed them about 5 weeks ago, and I have been trying to poison them ever since so I can open up the ceiling in the living room and remove the hive. This is the only time I have ever experienced a bee problem of any kind.

I wonder if bees are sensitive to environmental changes ...... makes me wonder ....
