My question involves an eviction in the state of: Texas

My daughter lives in our rental house, half the utilites are in her name and half in my name. She had a guest stay out the house for 2 weeks without our knowledge and let alone approval. Of course they are not on the lease, do not receive mail at the property and did not pay any rent. She is trying to get the guest our of the house and they are threating to take her to court for unlawful eviction. They also put their stuff in the shed outside and will not take it out.
Do the quest have any legal rights?
Can she tell them to pick up their stuff and put the stuff on the curb legally?
