What can I do when an evicted Tennet is breaking in my house?

I rented out my house to a lady and her 3 kids who didn’t pay rent for 5 months, I got her evicted thru the courthouse and she had x amount of days to pack and leave. She did leave but broke out the front door lock which I replaced and I also replaced rear door locks to be safe.

I think she comes midnight or early hours of mornings because I found candles in the house. She left behind a lot of valuables and even kept a dog locked in a room. I found bullets, and spice (drug) also. What can I do to make sure she doesn’t come by? Is the stuff in the house still considered hers? I was thinking of telling the cops so they can make rounds around that time but that didn’t seem reasonable
