I store a couple months at a time of chicken pellets, scratch, game bird starter, chick starter, game bird base mix, cracked corn, and sunflower. I have a room in our old concrete walled milkhouse that houses the feed, rabbits, and a freezer. The barncats can get in and I have a few sticky traps out. If I open a 50 lb bag of rabbit food, it goes in the big rubbermaid tote market rabbit food, and when scoop out from there, lock the lid after. I have not had any problems with mice going after the bags. Yet. It's been a year.
