Dryer sheets have worked for some people, but not for others. Buy a good bait and some tamperproof stations. They can be used both inside and also outside the garage around the perimeters. By having bait outside, you become proactive instead of reactive. If available look for a product called Contrac Blox. Never use Warfarin as most mice are immune to it. In case you are wondering, I own a pest control company. I have been dealing with these little scoundrels for over 30 years.
