Abstract
The present invention provides a method to control ecto-parasites of a host animals wherein 1-(2,6-difluorobenzoyl)-3-[2-fluoro-4-(1,1,2,3,3,3-hexafluoropropoxy)phenyl]urea is applied to the said host animals. By the method of the present invention, ecto-parasites of animals can be controlled effectively for a long period of time.
Claims12
The method to systemically control ecto-parasites of host animals through the host animal blood wherein a systemically effective amount of 1-(2,6-difluorobenzoyl)-3-(2-fluoro-4-(1,1,2,3,3,3-hexafluoropropoxy)phenyl)urea is applied to the said host animals.
A method to inhibit flea eggs produced on host animals from hatching wherein 1-(2,6-difluorobenzoyl)-3-[2-fluoro-4-(1,1,2,3,3,3-hexafluoropropoxy)phenyl]urea is applied to the said host animals.
The method to systemically control ecto-parasites of warm-blooded animals which comprises applying a systemically effective amount of 1-(2,6-difluorobenzoyl)-3-(2-fluoro-4-(1,1,2,3,3,3-hexafluoropropoxy)phenyl)urea to the animals and letting the ecto-parasites feed thereon.
The method to systemically control ecto-parasites of warm-blooded animals which comprises applying a systemically effective amount of 1-(2,6-difluorobenzoyl)-3-(2-fluoro-4-(1,1,2,3,3,3-hexafluoropropoxy)phenyl)urea to the animals and having the ecto-parasites ingest blood from the animals so that the ecto-parasite is exposed to an efficacious amount of the 1-(2,6-difluorobenzoyl)-3-(2-fluoro-4-(1,1,2,3,3,3-hexafluoropropoxy)phenyl)urea.
