we moved here in Dec 2012. the first few nights i didn't hear anything. then as the days went by i started hearing something moving around in the attic i put down on the paper they gave us. i thought it was rats, but the next month i was woke up by something hitting the window and i went out side, and what i saw was not rats but bats. i called the next day, and told them that we had bats. they said they would get right on it. 3 weeks passed nothing. called again they told me no one had called about bats. i called in Jan 2013. its now April and still nothing. i guess we have bats as roommates.
