How Do I Store Food to Keep Mice Away?

Utah State University Extension is specific: metal containers, glass bottles, and heavy plastic containers with tight-fitting lids are resistant to rodents, while paper boxes, plastic bags, and cellophane packages are easily accessible. Mice cannot chew through glass or metal; a thick hard-plastic container with a gasket seal is a solid second tier. Airtight seals also reduce the odor cues that draw mice in the first place.

Two realities make storage necessary but not sufficient. First, mice need very little food and are nibblers, so even crumbs sustain them — sanitation must be thorough, not just about big containers. Second, mice hoard food in hidden voids, so removing visible food may not immediately reduce an existing population. That's why extension guidance always pairs storage with exclusion: sealing every gap ¼ inch or larger with materials mice can't chew through.
