The scented flower arrangement is really the best way to keep bees calm. I also read that music helps, but it didn't do a thing for the bees in my game. Just wondering though, is the weather in your game currently hot or cold (not warm or cool)? I have noticed that bees don't like that, sometimes even when they are kept in the greenhouse and they got better after I turned on the thermostat.
Edit to add: If it is a temperature problem and you keep your bees outside, you can move the box against one of the walls of the house and extend the roof just a bit. The box should still be affected by the thermostat setting that way.
