Improved method for controlling ectoparasites

摘要

An improved method for controlling infestations of flies on an animal wherein a solution of an ectoparasiticide is applied to the skin or coat of the animal comprises increasing the concentration of the ectoparasiticide to about 3% to about 90% of the composition and proportionately reducing the volume of the solution administered to the animal such that the animal receives the same amount of the ectoparasiticide as it would have received prior to the concentration of the solution.
