How does my mother evict her granddaughter from her home in VA?

Mother is 84 and her granddaughter (my daughter) decided to visit her. She has now decided she is staying and is quite abusive verbally with my mother. She is paying no rent, helps with nothing and a slob. My mother lives in a small town in VA where everyone knows everyone. How can she quitely throw my daughter out without being the talk of the town? When I visit from Florida my daughter hides with friends until I leave then back to my mother's. My daughter has no money so I am sure she is most likely taking a few dollars here and there that my mother doesn't notice as my mother is legally blind.
