Objective To study and analyze the distribution and composition of floor fleas in households in west of Yunnan province, China, and to evaluate the risk of flea-borne diseases. Methods Ten counties (cities) in west of Yunnan, four villages from each of the county, and twenty households from each of the village were randomly selected, which made a total of 800 households as sampling sites. Ten water-containing plates were placed in each household for three consecutive nights. Fleas were collected every morning and species were identified under a microscope. The capture rate, flea index, species composition, and sex ratio were calculated. Results Of the 800 households, 346 (43.25% ) had floor fleas captured. A total of 24 000 plates were placed per night and 2406 fleas were captured. The capture rate was 10.03% and the flea index was 0.100. There were 5 species, 5 genera, and 3 families identified, and Pulex irritans accounted for 72.73% of all fleas captured. The female-to-male ratio was 1:0.65. Conclusion Among the floor fleas in households in west of Yunnan province, P. irritans is the predominant species. The conducive conditions and risk of flea-borne diseases still exist. To prevent the epidemic of flea-borne diseases, flea surveillance should be strengthened and flea control measures should be promptly taken.
