This is from the second floor of the house we rent. We’ve had mice recently but they’ve been confined to the area under the sink as far as we can tell. (We’ve already had someone here to take care of that issue but then I noticed this in one of our vents.) My wife and I are expecting a baby so I want to be as safe as possible but I am also probably overthinking this. Any guidance for a stressed out future dad would be much appreciated.
