For about two weeks now, we have been battling a smell. The evidence suggests that an animal, most likely a squirrel, entered our attic through a hole in an overhang and then burrowed through some insulation into the wall between our kitchen and dining room. And was then inconsiderate enough to die.
I had procrastinated about getting the hole fixed because I was afraid we'd trap some little animal in the attic or the walls, which would then die and stink up the place. Ain't irony fun.
At the moment, the smell is concentrated in our dining room, which is not the ideal location for it. We tried putting out coffee grounds, which absorb odors and have a strong and more pleasant odor of their own. Problem is, coffee doesn't just absorb odors -- it acquires them. After a while, the dining room smelled like the sort of flavored coffee that zombies might order.
Now we're trying baking soda and open doors and fans, and hoping all those little bacteria work overtime.
