mice problems in apartment

[Sasha Fukuda]

I have a four unit building and i was told by one of the tenants that she recently got a mouse infestation. I asked the previous property manager and she said that it happens every year, and that since the property is right by a mountain/ woods and mice are prominent in the area there's not much that can be done. Relatives have told me that it's a common problem just in general, as mice enter houses during the winter to get out of the cold. I was thinking of telling the tenant to put out mouse traps with peanut butter, and of me doing the same in common areas like the basement, but i was wondering if anyone had any suggestions? How do you deal with this problem?
