+2, ayrt has no idea what rodents are about, especially in an apartment building. you can be the cleanest person, and rats and mice will still travel for shelter, food or nesting resources if there's an infestation nearby, or if you have unattended holes in your walls or by your pipelines. yes, they'll thrive in a household with everyone's shit on the floor, but you're kidding yourself if you think you're safe from mice in perpetuity, especially if you don't live in a newly built home. there are many reasons to pick on dwrpers, but suffering through a rodent infestation ain't it.
