<human>: I've been hearing a lot of noise in my attic lately. What could be causing it?
<bot>: Possible causes for the noise you are hearing in your attic include rodents, birds, or bats living there, or even just air moving around. You should check to make sure that none of these animals are living in your attic and if so, try to remove them. If not, then you may need to contact a professional who can investigate further.
