Abstract: The occurrence of wild rats, their cestodes and ectoparasites in some farms and residential houses in Nsukka was investigated. A total of 101 wild rats were caught using traps and rodenticides. Ectoparasites and cestodes were collected on caught rats. The prevalence of wild rats in the various locations was 100%. Two types of rats identified as Rattus rattus (black) and R. norvegicus (Norway or brown) rats were caught. The prevalence of black rats (90.1%) was higher than that of the brown rats (9.9%). Fleas identified to be Xenopsylla sp. had a prevalence of 43%. However, fleas were not common among rats caught in residential homes. Lice had a prevalence of 7%. The prevalence of cestodes in the rats was 47%. Cestodes were common in both rats caught in the farms and residential houses. Wild rats were very common in some farms and residential houses in Nsukka. Rats served as a medium of transmission of fleas from location to location and can contaminate animal and human feed and water with cestode eggs. It is needful to regularly monitor the occurrence of rats and the parasites and control when their prevalence is soaring since they are zoonotic. Control measures were proposed.
