Seasons-What's up with Bees?

I started having the same issue, and after reading this thread I figured that the issue may have, indeed, been weather. First of all, the scented arrangement works really well. But if you're like me and you want to keep your plants and the bees outside, try putting a heating lamp next to the bee box. I'm currently in fall, my flower arrangement is long gone, and so far my bees have been calm all the time since I put the lamp next to them. I also put a small roof over the bee box, but I don't know if that really matters especially since I've had no rain to test if it affects the bees in any way.
