Bottom line from someone who had a major mouse problem in the house I bought a year ago. We have 1.5 acre wooded lot that borders on a big field. The house was neglected for years and empty for a year. I have taken a systematic approach to remedying the situation. First, stop poisoning outside. That's not good for the Eco system regardless of what anyone claims. Mice are fine if they're outdoors. Second, put bait stations throughout your house to get rid of the Immediate problem. Basement, garage, house sill, attic, knee walls, under your stove, behind fridge.....Every 10-20 feet in non living spaces. Usual mouse jaunts in living space..There are many more in there if you see one. They only forage thirty or so feet from their nest. Third, remove any ground cover from around your foundation. No vines, no juniper, no anything you can't prune off the ground. Give their predators a chance to do the job for you. Last, google exclusion methods. I went around my sill with hardwire mesh. Seal the inside of your sill at the basement or crawlspace with mesh with a caulk that dries hard. Make sure your garage doors and all other doors form a tight seal. Bastards are contortion artists and will exploit any opening they can. Seal around wire and pipe entry points. Make sure your sealant isn't easily removed. I disagree that your wood pile isn't an attractant for mice. Insects are only part of the reason it's recommended to stack wood more than twenty feet away from your structure. Mice don't have huge foraging ranges and giving them cover close to your house allows them safer passage while foraging. I haven't seen a sign of live mouse since taking these measures. I could go on and on, but the only thing you can do is work on exclusion to win this battle.
