Question: how do you know if you have mice or rats in your attic?
Answer: Though you'd like they'd be too quiet to hear, mice and rats do make a lot of noise, and hearing them can be one of the first signs of a rodent infestation. When they're in your attic, mice and rats make several sounds. You might hear scratching and gnawing as they crawl around or chew on your walls and wires.
