Objective To master the species and composition of ectozoa on the body of the rodents and hedgepig in Beijing ports. Methods Mus musculus, Rattus norvegicus, Apodemus agrarius and Erinaceus europaeus were captured by night trapping method, and the eetoza were collected from the body of them. Results A total of 282 eetozoas were picked up and identified, belonging to 12 species. It included 61 gamasid mite belonging to 6 species, 203 ticks belonging to 4 species, 13 chigger mite belonging to 1 species and 5 fleas belonging to 1 species.
