Abstract: An investigation was carried out on habitation pattern of rodent pests inhabiting in residential premises in countryside in Dongting plain area of Hunan Province, China. The result of the investigation indicated that Rattus norvegicus, Mus musculus, and Rattus flavipectus were the main rodent species inhabiting in farmhouse. Generally , the trap-successes are the highest in the kitchen, followed by hovel, and the lowest are in bedroom. The investigation indicated that the types of floors and the building structures of farmhouses were the factors influencing the activity and habitation of rodent pests. The trap successes of rodent pests in the houses with fired brick wall and concrete floor were low and the species trapped were mainly house mice. However, the trap successes in the houses with clay brick or wood wall and clay floor were much higher and the species trapped were mainly Norway rats with high proportion of house mice. Moreover , the living standard and living custom of farmers also affected the activities and inhabitation of rodent pests. The rodent densities were much lower in tidy and clean houses and the dominant species were house mice rather than Norway rats. Therefore, in order to have the best rodent pest control, relevant control measures should be employed according to various environmental conditions such as building structures of the farmhouses, living customs of farmers, rodent density, and dominant rodent species.
