This ready-to-use pour-on insecticide controls horn flies, face flies, and both biting and sucking lice on beef and dairy cattle, including lactating animals. No mixing is required, and only a small amount is needed per treatment. It can be used year-round on cattle of any age or size with no meat or milk withdrawal periods. Application is simple—pour along the top of the animal’s back and head. The active ingredient is 1.0 percent cyfluthrin, providing convenient, versatile, and effective pest control for indoor and outdoor use.
