The affect of these species on human populations ranges from inconvenient to lethal. Crops are harmed prior to harvest; saved foods is contaminated by rodent waste; h2o-impounding constructions leak from burrowing; and objects are weakened by gnawing.
Numerous types of shelters are employed or manufactured; these range from tree holes, rock crevices, or straightforward burrows to concealed nests around the forest ground, leaf and stick structures in tree crowns, mounds of Lower vegetation built in aquatic environments, or sophisticated networks of tunnels and galleries. Rodents can be Energetic all yr or enter intervals of dormancy or deep hibernation.
