Hi Liz, Borrow someone's Cats.............
Here’s what worked for us: https://www.frugalfamilytimes.com/2018/10/how-to-get-rid-of-mice-rodent-proofing.html?m=1
Traps and close up every tiny nook and cranny.
Soak a rag with ammonia and place in their holes. They’ll leave and never come back.
Use Peanut Butter on your mousetrap because the mice cannot get the Peanut Butter off the traps like they can the cheese!!
