The article considers the problems of deratization efficiency at regulation of house mouse populations in various premises of the city of Tyumen. The results of the conducted research show that deratization leads rather to increase of rodents by 1.4 times. Under the influence of anthropogenous aspects (firstly, toxic ones) and due to sanitary and epidemiologic processing of premises with rodenticides, the house mice inhabiting the derated premises are inhibited. Their morphological and physiological indicators (absolute and relative body weight, heart index, liver index, index of kidneys, index of adrenal glands, spleen index) are changing. These changes confirm increasing metabolism, energy metabolism, and general organism stress. There are insignificant distinctions in sexual structure of micropopulations of the house mice inhabiting derated and non-derated premises: the amount of females and young animals increases after deratization. In the derated premises, the reproductive success is decreasing by 1.4 times. Thus, deratization efficiency is low due to the inflow of animals from adjacent territories which worsens the general sanitary and epidemiologic situation in the premises.
