I've been fighting mice for 20 years in our home in the woods. Hard to keep them out, they can get into the smallest holes. But I finally found a solution about three months ago. Strobe lights.
Mice usually came into my house through the garage or attic. So I set up cheap strobe lights in both places and put them on a smart-plug timer to come on and off at sunset and sunrise. They may still try to get into the house, but the strobe lights must freak them out and they leave. So far since I started doing this I've had no mice. First time in 20 years I went through a winter without them trying to live in my house.
Poison's are the worst solution, the mice just end up dead in the walls and stink up the house for weeks. Traps are fine, but it doesn't stop them from coming in and breading and it's a huge hassle and disgusting to deal with traps constantly. The strobe lights are genius, as is the person that discovered using them (wasn't me) against rodents. Wish I would have found this out years ago.
Only downside is if you have mice from the 70s that like discos.
