Fluazuron is an insect growth regulator with activity against larvae of Amblyomma sculptum. Fluazuron exhibits 100% efficacy by interfering with the molting process. Fluazuron has shown rapid absorption and slow metabolism in experiments. The use of Fluazuron offers a potential preventive measure for the control of Brazilian spotted fever. The results of Fluazuron offer good prospects for the development of feed products containing FLU to control ticks in free-living capybaras[1].
