How do you refuse to let certain unlawful, immoral relatives come over?

I have two close relatives, really close, who lie, steal, run away from the sheriff , hit each other, do lots of drugs, damage my furniture on purpose but act really hurt when I don’t want them over here after I’ve not seen them in over a year. They act so insulted when I give them some excuse. I would actually like to see them every couple of years for a few hours but these are the types you can’t get rid of that give you heart palpitations. One of them should be in a mental hospital. I don’t want to be a bad person but I also don’t want to have to hide half our belongings either. What should I say?
