Well, instead of poison, i would reccommend using one of those humane mouse traps that are poisionless and you can let the mouse go somewhere away from your house instaed of making a innoccent animal suffer with mouse traps and poison while its just trying to keep alive. Im not saying that mice arent pests but i am saying that mice are just little animals who just ended up in human homes. I hope that you do get a humane mouse trap instead of poison and regular mouse traps.
