Should I evict the people living under my ?

A year and a half ago a man that I met called Nicolas Cage greeted me at a coffee-shop, telling me that he had run out of money, had no job, and just lost his home. Feeling sorry for him, I told him that he could start living under my as long as he kept my pubic areas groomed; he did fine, however about two months ago he starting bringing all his drunk friends along and trashing my with beer and drugs; two of his friends have stayed permanently, Johnny Depp and Will Farrell. It often leads odd looking stains on my pants whenever they have a party. So once again, should I evict these people from under my ?
