The mean tick counts and the detailed efficacy results are shown in Table 1. Tick-killing efficacy was 89.6% at 4 hours, 97.9% at 8 hours, and 100% at 12 and 24 hours after treatment. Eight hours after re-infestation, efficacy was 96.8%,83.5%, and 45.8% at 4, 8, and 12 weeks after treatment,respectively.
