My friend, who is also a beekeeper, has serious problems with bees in the walls of his new yellow repainted
house. His apiary is in the nothern side of  the house with entrance to the SE.   During the day, the southern side of the house became warm and plenty of bees stopped there and   the new repainted wall became dirty. My friend don't want to move the bees neither to repaint the house with the different color. Has anybody any advice for him?  Has anybody ever met with such problem?  Thanks for your answers,
