Grandparents rights toward grandchildren

I'm a single parent living in west virginia. I'm having problems with my two boys and their behavior more to the point their lying. Because of this I refuse to let them go and stay with my parents for the weekend and or a week at a time because of this behavior. My mother threatens me with the court system saying that she will get a lawyer and force me in court to allow her to see the kids. I only take away the weekend and holiday visits as a tool for punishment. Can she take me to court and can she force me to allow the kids to visit? Thank you

Not according to the U.S. Supreme Court ruling last year in Troxel v. Granville. They left it up to the parents to decide.
