Remember that poison I put out for the chipmunks to enjoy? Well now, the mice got it too, and no, they do NOT go outside to die. So that's the rest of the story. Now I get to hunt for carcasses in the hard to reach places where ever my nose leads me.
Brad found the first dead critter by the washer quietly decomposing almost in plain sight. (I just didn't expect to find dead mice in the wash room, I guess.) He took it out and now I can breathe in that room.
Our sitting room and bedroom downstairs are under suspicion only, so far. I am dreading the idea of trying to lift tiles where there is almost no extra space and looking for critters...it could get interesting.
