Only had one mouse-icide, back when I was single. Kenny startled me one evening by running across the floor of my living room while I was reading. It was one of those “did I just see what I thought I saw?” moments, because what mouse runs out in the open with people there? Then I found little mouse treats on the kitchen counter, and it was time to kill Kenny. One single-use trap and a couple days later, it was over. Trap + body went in a bag that went in the trash — bastard never did anything to deserve a decent Christian burial. Then apparently after I killed Kenny, word got around.
With Deb, we may have seen one mouse once, in the garage; we have poison out there, and no sightings in years.
