Put traps out. But you also must find where they are coming from! Mice can get in areas the size of a quarter so block everything with steel wool.
Here’s what worked for us: https://www.frugalfamilytimes.com/2018/10/how-to-get-rid-of-mice-rodent-proofing.html?m=1
Seal up even tiny openings. Traps are better than poison since they may die in an inaccessible areas.
Get a spray bottle. Fill it with water and peppermint oil. Spray around all baseboards and doors. I had mice for 15 years until I did this. Now I haven’t had them for the past 4 years! 😊
