When you live out in the country - you're on their turf. I've got so many here that I can see them jumping in the grass infront of the lawnmower. My shed is loaded with them. I took out the christmas decorations and in one box alone - I killed 12. Thankfully, we don't have them in the house, garage, basement, or attic. The old fashion snap traps with Peanut butter works best. I've trapped and killed atleast 40 in the last 2.5 years and there seems to be an endless supply from the woods, bottomland, and tall grass. The mice were here long before me.
