The black rat is a synanthrope, widespread both in towns and in rural areas. It inhabits houses, storages, trade and production facilities, cattle farms etc. Usually, it settles in cellars, flooring, and attics. In the summer, it moves to land plots with thick grass, where it digs holes to live in. In the fall, the black rat returns indoors. The species is mainly herbivorous. In certain areas, it is extremely abundant.
