Mice are primarily nut and seed eaters, so the mouse trap bait they are most strongly attracted to is peanut butter or hazelnut spread. Their hunger for calories also entices them to try chocolate. Other sweet snacks like gumdrops, marshmallows, and candy are also effective in attracting mice. Hot dogs, cheese, and pet food are other options that can be used as bait. When using peanut butter or other food bait, it is important to avoid spreading too much on the trap. A pea-sized amount of bait is just right - enough to attract mice, but not so much that they can eat it without springing the trap. Additionally, it is recommended to place mouse traps along walls where mice primarily travel, with the bait and trigger end of the trap facing the wall so that mice will be tempted to explore them rather than walk around them.
