Objective To investigate tick infestation of a war readiness warehouse and its influencing factors and evaluate the outcome of the control measures. Methods The visual method, chemical stimulating method and the technique of dragging a blanket over the vegetation on the grounds were used for the survey on the tick damage and observation of the effects of tick prevention and control. Results The average tick bearing index in dog reached 2520, with the tick density in the war readiness warehouse between 8/400 cm2 to 200/400 cm2. The range where ticks infringed was consistent with that in which dogs were fed. Residual spray in the indoor environment was administered using the mixture of 0.2% fendona and 0.3% propoxur. D-cyphenothrin, with conventional spray done with 0.1% cyhalothrin and 2% fenthion in an outdoor environment. The density of ticks decreased to less than 3/400 cm2 after the first spray and to zero after the second one. Conclusion Two residual sprays combined with the control of dog ticks in the environment contribute to the effective control of tick damage to the warehouse.
