The present invention provides an ectoparasiticide composition for animals having excellent photostability and a capability to suppress photodecomposition of the active ingredient, comprising etoxazole as an active ingredient, a UV absorber and a phenol antioxidant, and a method for exterminating ectoparasites using the composition.
By using a UV absorber and a phenol antioxidant in combination, a remarkable synergy effect is provided on photostability of the composition. The preferable blending ratio between etoxazole, a UV absorber and a phenol antioxidant in terms of mass ratio is 1:from 0.05 to 5:from 0.05 to 5.
