Might have to do the landlord/tenant thing with eviction notice by certified letter etc to satisfy the legalities in that state, but yeah… this.
Also, locks changed / upgraded and alarm system installed. Also notify his attorney, the court, local PD and any parole officer that he’s not living there & is not welcome there under any circumstances (restraining order?).
The parents might want to think about what valuables Butch knows they have in the house & rent a safety deposit box. If he knows the combo to their safe, its no longer “safe”. Remember, while he’s using they might be able to keep him out,
but he’ll sell/tell everything he knows about how to take down their house for more drugs… and probably to a crew that Can take down their house.
Parents: Do. Not. Cave.
