What Is the Best Bait for Mouse Traps?

University extension guidance names peanut butter, chocolate candy, dried fruit, or a small piece of bacon tied securely to the trigger. Peanut butter is the workhorse — its strong nutty aroma and sticky texture make it hard to remove without springing the trap. Chocolate is a solid alternative, especially where peanut butter has been overused in a home; dark chocolate's stronger aroma helps, and pressing it onto the trigger so it re-hardens makes it steal-resistant.

A small tuft of cotton wool, dental floss, or yarn tied to the trigger can outperform food bait, because female mice actively gather soft fibers for nests — particularly in autumn and winter as mice establish winter nests, or whenever food baits are being ignored because the home already offers abundant competing food. Seeds and nuts, like sunflower or pumpkin seed, also work well since mice naturally gnaw seeds.

Use a pea-sized amount — too much lets the mouse feed without triggering the trap — and place traps against walls in dark, traveled areas, since mice run edges rather than open floor. And debunk the cheese myth: mice will eat cheese, but it ranks low versus fatty, sweet, and seed-based options.
