Bizarre this one - some bees seem to have taken up residence in my boiler overflow pipe, all 15mm of it. There don't appear to be very many of them, it being a rather small residence, but I don't really like the idea of beeswax stuffing up one of the things between me and an exploding kitchen.
Anyone got any suggestions? I don't want to kill them, given they;re bees rather than wasps. Just persuade them to take up residence elsewhere...
