There is a distinct odor in the cellar

When I first smelled it, I was getting something out of the refrigerator. It smelled like something died in it. Later that day I remembered that corner is where the pest control guy said he could see mouse activity in the insulation.

Back in college I took a class (I can't remember it's title) where all us students each received a dead rat and found a location outside to put it to study it's decomposition. [Fascinating class. I'll tell you more if you want.] So, I know what dead animal smells like.

It's been about two weeks since we put the poison out. You take a guess as to what I am smelling.
