We have a ton this year! Have never had any trouble in the nine years we've lived here in the country, but we had a wet spring and summer. We've caught about 16 (!) since Thanksgiving. I am NOT a mouse fan, for sure and they have found hantavirus in mice in our county, so I'm constantly looking for poop or pee and wiping everything down with bleach wipes. Dh found a YouTube where a guy suggested using a piece of tootsie roll for bait. You chew it a bit to soften it and put it on the bait thing on a snap trap. Works like a charm! It sticks to the trap so they can't steal the bait.
