If there is a possible mice in the apartment what rooms are the people going put traps?

I like in an apartment and next door is another apartment but we both enter the same door if that makes sense. My landlord lives with me and she told me that some people will be coming to check if there’s holes etc bc people on the other side are having mice problem. So where exactly are they going check bathroom , kitchen only? Only the whole 4 bedrooms? The 8 roommates I have , have not seen anything
