I live in the country. This is the worst year yet for field mice moving in my shop. I've tried traps, repellent(peppermint and cinnamon oil). I've cleaned, tried sealing every opening around the shop. I have the mouseblocker pro advertised on car shows. They run right by it. I have poison, have not resorted to it don't like the dead mouse smell, but I think I am to that point. I have rat snakes around, but they can only eat so much, LOL. Help!!!!
