Mice especially enjoy salty meats like bacon bits and slices of hot dogs. Peanut butter, crackers and chocolate are also good baits. Extra credit: If you notice that mice are eating certain items in your pantry, bait traps with the same foods. They'll be more likely to go for the foods they're used to eating.
Tip #4: Hold the cheese. As you may know, mice will eat most things. Sure, they’ll eat cheese - it's delicious. But despite what cartoons will have you believe, cheese isn't a mouse's first choice, so save it for yourself.
