Fenpropathrin was investigated for its efficacy as an acaricide for controlling ticks on grazing cattle. Treatment trials were conducted on beef cattle at the Matsue municipal pasture in Okushiri-cho, Hokkaido between June 9 to July 7 in 1995. On the first day, the ticks were counted on the cows and the medication was poured on each animal used in the experimental group. During the trial, ticks were counted every 7 days. The tick index (ratio of mean number of ticks parasitized on experimental group cattle per those of control ones) dropped 7 days after treatment: adult ticks (37.0%) and nymphs (34.7%). The index rose slowly again but remained low for 4 weeks following treatment. No local or general side effect were observed in the cattle treated. Fenpropathrin was considered an effective and safety acaricide with long-term efficacy for managing tick infestation of cows grazing on pasture
