The snap trap has been the most popular type of mouse trap for over a century. To use these traps, you set a U-shaped bar into position with a spring mechanism, which gets triggered once the mouse takes the bait. Peanut butter and cheese are the top two choices for bait, but some snap traps come "pre-baited," for added convenience.
Pros. Snap traps, like glue traps and live traps, are inexpensive. They're also considered humane because they work by killing a mouse instantly without prolonged suffering, as with electronic traps.
Cons. Children and pets can get hurt if they come in contact with a snap trap and accidentally trigger the spring mechanism. Also, viewing the remains can make people squeamish. However, you can buy a covered snap trap and take care to place your traps in inaccessible locations to prevent injury.
