Mice can be cute. They have fuzzy little faces and big eyes. However, their cuteness soon fades away when you realize just how much damage they can do to everything in your garage. They can chew through the garage door opener, which could mean you can’t get into and out of your garage. They can get into your boxes of photos and other keepsakes and damage them with their waste or by simply gnawing through them. You do not want mice or other pests in your garage.
