The range of house mice can be about 30 feet — but in reality, their range depends on the distance between a good place to live and a preferred food source. This might be 30 inches, 30 feet or even 30 yards.
Effective control depends on a thorough inspection to locate all nesting and feeding sites. Control devices and materials can then be placed on travel routes, so as to intercept them between their food and harborage. It also is important to use enough traps and/or rodenticide, so every rodent has an opportunity to partake.
