The house mouse is the most encountered and economically significant rodent. While house mice are nuisances, they can also pose important health and property threats.

House mice breed rapidly and can adapt very quickly to changing conditions. A female house mouse can give birth to a half dozen babies every three weeks and produce up to 35 babies yearly. They can also fit into tiny spaces allowing them to move around the home quickly and efficiently. For instance, the typical house mouse can squeeze through openings as small as a dime.
