A parasitological study was done on commensal rodents in Kingfisher Park, Sabah. The study was primarily conducted to determine the infestation rates of ectoparasites on the rat specimens. The data collected was also used to determine differences among location, gender and infestation rates. A total of 34 individual rats were captured. The 34 individuals were successfully divided into three rat species which were Rattus norvegicus, Rattus exulans and Rattus argentiventer. From those 34 rats a total of 634 positive counts of ectoparasites were recorded. The 634 individual ectoparasites were then identified and divided into 11 major broad groups; Polyplax spl, Polyplax sp2, Polyplax sp3, Polyplax spinulosa, Dermatophagoides spJ, Dermatophagoides sp2, Omithonyssus bacoti, lice morphospecies sp 1, lice morpho species sp2, mite chigger morphospecies spl and mite chigger morphospecies sp2. Dermatophagoides sp2 was the species with the highest individual count; where 167 individuals were detected, and lice morphospecies sp2 with 7 individuals were the least found. The total infestation rate obtained from the 34 rats in Kingfisher Park was 91.18%. Mann-Whitney U test on the genders resulted with U=111.00, Z= -1.189, and p= 0.234. The observed p-value was larger than the expected p-value. The means of infestation rates based on genders did not have any significant difference. The Kruskal-Wallis test was used for the sampling location and resulted X2 = 28.493, df= 2, p = .000 which means that there was significant differences with the infestation rates between locations, the p-value is smaller than .05. The differences was detected between sampling location in the open area with a mean rank of 9.00 and the commercial area with a mean rank of30.00.
