yes. I let my late half brother addicted to drugs stay with me once. He kept breaking back in. I knew of some crimes he committed in other cities cuz he was dumb enough to brag about them. So I posted a note on my door that if he came near my house again I was filing criminal trespass charges against him. That kept him away. If they are using illicit drugs you might can use that as criminal trespass. But the law is you have to inform them of not being welcome and that you’ll file charges for police to honor it. Best if someone is witness but posting a note on door will work too. If he has a phone I’d call and tell him too. My brother’s behavior got very criminal and dangerous in the end,
