A mouse is capable of getting through an opening only one quarter of an inch wide. It is important to check for openings where mice can gain entry, such as openings around doors, windows, foundations, and vents. If you live in a mobile home or have a crawl space, check around plumbing pipes inside cabinets for spaces mice can get in. Using steel wool to fill in cracks and openings to temporarily keep mice out is  a good remedy.

There are various types of traps that can be used to capture or kill mice. Traps are advantageous since poisons can be dangerous, and with traps the dead mice can easily be located and disposed of. When poisons are used, the mice often die and are not found until there is an odor. Also, poisoned mice can pose a danger to pets that may eat them. A good bait to attract mice is peanut butter. It is not easily removed without setting off the trap.

Live traps can trap more than one mouse at a time, and the mice can be released without harm in another location. Glue traps will hold mice with a special glue, but they can be ineffective with high temperatures or in dusty locations. It is advised to use caution when placing any traps where pets and children can access them.
