I had 2 mice in 2017, 1 in 2018.I never want to chase 2 mice around the house for 2 weeks like I did in 2017. They Chit more than a Goose. I learned to go full force- 6 traps, sticky things and poison when I first saw one that was actually 3 mice in years back. I have attached garage and fixed the weather striping on garage door and set traps in garage. I checked outside for holes and cracks. Last year, I saw a mouse run up my bricks when I was taking in the hose and went under the soffit(aluminum ). I filled a few Mortar lines that looked larger than the others and threw poison cubes in attic and never saw him again. I also have a fireplace chimney. How do you guys prevent mice from entering your house or garage in the Fall ? Spray entry ways (garage door/sliding screen door)? Poisons cubes on the outside ?
