The house mouse is the most common rodent pest in most parts of the world. It can breed rapidly and adapt quickly to changing conditions. 


House mice can breed throughout the year and can share nests.


House mice live in structures, but they can live outdoors.


Microdroplets of mouse urine can cause allergies in children. Mice can also bring fleas, mites, ticks, and lice into your home.


To keep mice and other rodents out, make sure all holes of larger diameter than a pencil are sealed. Mice can squeeze through spaces as small as a nickel. Seal any cracks and voids. Don’t overlook proper drainage at the foundation and always install gutters or diverts which will channel water away from the building.
