Can mice get into your apartments? and can they get in more than houses.?

Sure, they often live in the walls or other vacant spaces (or even under the appliances) and can eat thru drywall and wood (but not metal and don't like eating plastic though they can). It is more unusual to have them in apartments the higher you go above the ground floor but it does happen.

Of course they can and do, lots of people have mice in their home and don't even realise it, they can get in a hole no bigger than your finger nail or via pipes and breed like mad

Why don't you put sugary food on the floor of your car, leave the door open and you'll find out?

Yes they can get into an apartment or a house. A rodent can get in through a much smaller hole than people think.

Yes, mice can get into houses, apartment, mobile homes, cars, etc. They are very pesky creatures.

Yeah so can bugs and cockroaches.
