You catch mice under the seat inside your wife's car?
And she'll still willingly get in and drive it?
Maybe you didn't inform her of their presence?
There's so much dust and debris floating around under the seats (everywhere actually) in my truck, I think it would defeat the sticky overnight. But then I've never had mice/rodents inside my truck...
I've been catching mice inside the house here off and on all winter. I have no idea where they're coming in at... I'm on a solid concrete foundation all the way around... I discovered they were even in here because I was standing at the counter and though a saw a shadow go running across the floor ending under the stove. I smacked that one with a broom handle and threw it outside. Some times I'll go days in a row finding the peanut butter completely licked off the paddle... even though I force it into the folded area. Right now, I've gone over a week with nothing touching the traps... but I don't know if I got them all or not. I'd guess not. I want to try one of the zap traps just too lazy and cheap to go buy one.
