Last year, I caught something over 20 mice in our house between December and February. We have small dogs so poison was out of the question. I deployed a dozen humane (live) traps baited with peanut butter, which didn’t catch anything, and about 30 glue traps behind furniture, which only caught two or three mice. The big winners were the four quick-kill traps baited with peanut butter which I put under our kitchen sink. I got 16 or 17 with those.
