Question for bee experts

[limax2]

While gazing through my kitchen window I can see the gable end front corner of next doors bungalow. I have noticed recently a constant coming and going of bees under the fascia board. Behind that gable end is the garage. Now, if I tell the old dear next door she will worry about it and ask me what she should do. Since I don't know I am asking here first. I know bees perform a vital function but I guess nobody wants to share their house with them.
