Mice seek three things: food, water, and shelter. Crumbs, open food containers, pet food, warm hiding spots, and easy entry points all attract mice. They can squeeze through holes as small as a dime (6mm). The #1 attractant is easily accessible food — securing all food sources is your first line of defense.

Results vary significantly. Some homeowners report success with ultrasonic devices, but scientific evidence is mixed. They work best as part of a combined strategy that includes sealing entry points and removing food sources. Read our full test results.

Look in dark, secluded areas: behind appliances, in attics, basements, wall voids, and cluttered storage areas. Signs include shredded paper or fabric, droppings, urine trails, and a distinctive musky odor. Our identification guide has photos and detailed walkthroughs.

Most natural repellents like peppermint oil are safe when used properly. However, some essential oils can be toxic to cats. Always research specific pet safety before using any repellent in areas accessible to your animals. Our natural solutions guide includes pet safety ratings.

Call a professional if you have a large infestation (mice visible during daylight), can’t locate entry points, DIY methods haven’t worked after 2-3 weeks, or you’re finding extensive structural damage. Early professional intervention can save thousands in repairs.
