I had mice in my house this past winter. I was looking around in a cupboard and found a bag of popcorn that was chewed open, with a nice pile of partially eaten kernels all over the place. Traps didn't work; they ate the bait and left the trap unsprung, so with some trepidation I used D-Con to get rid of them. Luckily, no smell from dead carcasses. They must have been living in the crawl space under the house. Apparently they loved eating the D-Con; I had to replace the box every few days for two weeks until the stuff was finally sitting there without any rodents eating it. From what I understand, they die a pretty unpleasant death from that stuff. Oh well. I don't want rabies infected varmints running around in my house!
