Something I've never seen mentioned here or elsewhere is the problem of bee poo raining down on a wide area around the hives.
My hives are 50m away from the house but the windows (and anything around)are continually dotted with orange waxy blobs that are difficult for the window cleaner to remove. Even worse my car (and probably those of neighbours) is often covered with them if I don't put it in the garage. It was terrible last year when there was a field of OSR in front of the house, but it's still annoying. Doesn't anyone else notice this?
