You can use any foods on the mouse trap to attract the mouse and kill them.
Peanut Butter is good for mouse traps since the peanut butter will stick to the mousetrap making it harder for the mouse to get it off without triggering the mousetrap.
The mouse will have to work at getting the peanut butter off the mouse trap which will then trigger the mouse trap and kill them.
Cheese is also a good bait to put on mouse traps because mice really love cheese and are attracted to it but just make sure you push the cheese into the mouse trap to make it hard for the mouse to easily get it off.
