Objective To investigate the flea control effect in some rural residential areas of Xinjiang Uygur autonomous region, China. Methods Some rural residential areas in Xinjiang were selected as the experimental areas, and 8% beta-cypermethrin wettable powder diluted 100 times was used to control the fleas via residual spraying. The flea infestation rate, flea index, and biting rate were compared before and after the flea control to evaluate the control effect. The independent samples t-test or one-way analysis of variance and chi-square test were used to compare the flea index, flea infestation rate, and biting rate. Results Before the flea control, the flea infestation rate was 86.25% (69/80) and the total flea index was 0.23 (213/914), with no significant differences between different villages (P=0.599, Fisher's exact test; F=0.103, P=0.924). The biting rate was 62.71% (148/236), 89.47% (34/38), and 83.82% (57/68), respectively, in adults, young children (6 months to 4 years of age), and elder children (6-8 years of age). The biting rate was significantly higher in young and elder children than in adults (χ2=10.510, P=0.001; χ2=10.714,P=0.001). The biting rate of cadres stationed in the villages was 76.29% (74/97). On days 2-3 after the flea control, the flea infestation rate and total flea index were significantly reduced to 6.25% (5/80) and 0.02 (19/914), respectively (χ2=102.979, P<0.001; t=38.476, P<0.001); the biting rate was significantly reduced to 4.41% (10/227), 8.11% (3/37), and 6.06% (4/66), respectively, in adults, young children, and elder children (χ2=174.983, 49.653, and 85.613, all P<0.001); the biting rate of cadres stationed in the villages was significantly reduced to 2.94% (3/102) (χ2=112.757, P<0.001). Conclusion Residual spraying with 8% beta-cypermethrin wettable powder diluted 100 times had a good effect of flea control in the rural residential areas in Xinjiang, which holds promise for application.
