CyLence pour-on is a cattle insecticide used on both beef and dairy cattle of any age for control of biting and sucking lice, as well as face and horn flies. The cyfluthrin pour-on treatment for flies can be repeated as needed, but not more than every three weeks. For optimal lice control, a second treatment three weeks after initial application is recommended.
