Nearly every country in the world has a rodent population, with the exception of Antarctica, New Zealand, and some other islands in the ocean. Rodents can live in a number of habitats including deserts, rainforests, grasslands, swamps, and deciduous and coniferous forests. In the wild, some mice live in burrows while others choose piles of brush, vegetation, wood or rock piles, and ditches to call home. Rats will collect materials such as twigs, plants, and cotton and create nests in hollowed logs and other areas where they feel protected from the elements.
Once rodents have made their way inside, they will choose a sheltered area to make their nest. These may include in wall voids, attics, crawlspaces, and garages. Mice in particular will also seek out warm areas, such as underneath kitchen appliances or in kitchen cabinets where they are close to a food source. Roof rats will either live on the roof or in other high areas, such as in an attic.
