I think I have some mice in my third floor wall. Heard some noise from the third floor one night while sleeping. Sounded like debris falling inside the wall. Went up to check it out yesterday. We have some rot on the hardwood floor where the previous owner had an A/C. A lot of the wood from the rotted area has been removed and there seems to be a hole in the wall (reminds me of Tom and Jerry). I am guessing there are mice in there. Obviously, I need to get rid of these mice. My question is: what is the best way to do that? Poison, glue trap, conventional trap? If I put of some poison and the mice die in the wall do I have to worry about them smelling? Any advice would be appreciated. Thanks.
