exterminators
We finally called an exterminator to do something about our mouse(mice)/rat(s). He came by yesterday and apparently told my housemate Kyle that it was physically impossible for rats to get into our walls because of the way they are constructed. What we were hearing, he insisted, was the tree outside brushing up against our house. Wow. I never knew trees could make chewing noises or throw their voices to interior walls. We have a different exterminator coming to check things out tomorrow.
