But there is no proven universal “top five” ranking: mice may respond best to food they already eat, and nesting material can be worth trying when food is plentiful. Start with a small amount, set the trap where mice travel, and keep it inaccessible to children and pets.
Five practical baits for mouse traps
These are useful options for different circumstances, not a measured ranking by catch rate. UC IPM says familiar food is often the best bait, while extension guidance identifies several other foods and nesting materials as possibilities. The available guidance does not establish that any one option catches more mice than the others.
| Bait | When to try it | Practical considerations |
|---|---|---|
| Peanut butter | A straightforward first choice when it is safe for the household. | Use a small amount on the bait pan. UC IPM describes it as popular, easy to use and attractive to house mice; peanut allergy is a concern in some households. UC IPM and the CDC recommend it. |
| Food the mice already eat | When you can identify food the mice are reaching, such as grain products, bird seed or dry pet food. | Familiar food may be more relevant than a new lure. Nevada Extension notes these foods are preferred by house mice in homes. Secure solid pieces to the trigger where needed. Nevada Extension and Oregon State Extension discuss food baits. |
| Nuts or nut meats | As a food-bait alternative when suitable for the household. | Oregon State Extension lists nuts as a good bait. Consider allergy concerns, and fasten a solid piece to the trigger so the mouse has to engage it. |
| Dried fruit or cheese | When these foods are familiar or peanut butter is unsuitable or ignored. | Oregon State Extension lists both as good baits. This does not establish that either outperforms peanut butter or works in every home. |
| Cotton wool or dental floss | As a non-food lure when a nest-building female may be present, or when accessible food is abundant. | UC IPM identifies cotton wool and dental floss as possible nesting-material baits; Nevada Extension describes cotton as a possible lure when food is abundant. This is a different approach from food bait. |
Choose bait based on the mouse and the household
Start with familiar food
Look for accessible food near signs of activity, including nibbled food, droppings or gnaw marks. If mice are getting into bird seed or dry pet food, baiting with a familiar food is a reasonable option. Removing those food sources is also important: Oregon State Extension’s mouse-management guidance pairs trapping with food removal and sealing entry points.
Consider allergy and access
Do not use peanut butter if peanut exposure is unsafe for someone in the household. Whatever bait you choose, keep both the bait and the trap out of children’s and pets’ reach, as the CDC advises.

Make the bait engage the trigger
Use a small amount rather than a large lump. UC IPM notes that a mouse may remove excess bait without springing the trap; a small quantity encourages contact with the trigger. For solid bait, such as a nut, Oregon State Extension recommends fastening it to the trigger.

Set the trap where mice travel
- Choose a mouse-sized snap trap. Follow the trap maker’s instructions; the CDC distinguishes mouse traps from rat traps.
- Bait the pan lightly. The CDC recommends a small amount of chunky peanut butter or mutton fat on the bait pan. If using another food, keep it secured to the trigger.
- Place the trap beside a wall near activity. Set it on the floor with the baited end next to the wall, so the trap forms a T against it. Choose a spot near droppings, gnaw marks or nibbled food.
- Keep it inaccessible to children and pets. Check the trap daily, following the CDC’s household guidance.
What to do if the trap is not working
- If bait disappears without a catch: reduce the amount and make sure it is attached to the trigger. Recheck that the trap is positioned against a wall near evidence of mouse activity.
- If mice ignore the bait: try a food they already access, or consider a different option from the table. If food is abundant, a nesting-material lure may be worth trying.
- If activity continues: trapping alone may not address the conditions sustaining mice. Remove accessible food and seal entry points. The CDC advises considering an appropriate bait station or professional help if rodent activity persists despite trapping.
