Help! I can't get pet odor out of my new house!
I recently purchased a home in which the sellers kept two large dogs and two cats confined to an unfinished room in the basement. I have bleached the floor, used a commercial fan, and scrubbed and scrubbed. The odor is still present. It is much less overwhelming than before, but still quite unbearable. The rest of the basement has an indoor/outdoor carpet in place. There is no pad underneath. I did shampoo this carpet as well.
What else can I do? Can this odor be in the walls? Has anyone else had this problem? Any advice would be greatly appreciated.
