I was getting pwned by mice this week. A crack team of ninja mice were stealing the bait from my traps without setting them off. I can't find my Victors, so I'm using an inferior Taiwanese design. I had the bait stolen about six times. I use old Nutella as bait. It's extremely stiff, and sticks to the bait pan well. The traps should have sprung, but the bait pans were nice and clean every time I'd check them. I eventually got the bastards. One I felt kind of bad about. It was a female with swollen tits. If she already gave birth, there's probably some hungry mouslings in the wall somewhere.
Oh well... If they'd just be cool, and move in without chewing the hell out of stuff, I'd leave them alone. I'd even put food and water out for them if they promised to move in the spring, but as long as they act like assholes, they'll get their little necks broken. Either that, or my ferocious kitty will play with them until I get tired f hearing the noise, and have to take mousey for a long walk, but either way, they can't be in the house.
