Attic issues

[heehaw]

my mother in law poisoned some mice, what seems like a long long time ago, and the smell is still there: i am going to say close to a year, maybe longer. luckily its not real bad, just a faint odor in the basement. i keep thinking it will eventually go away?? can't you cut an access hole in the ceiling, or check inside the closets, i've seen a lot of small 2ftx2ft access holes hidden in side closets.
