Directions For Use

It is a violation of Federal law to use this product in a manner inconsistent with its labeling. Reformulation or repackaging of this product is prohibited. The labeling must be in the possession of the user at the time of pesticide application.

NOTE: When applying tags, wear chemical-resistant gloves made of rubber or any waterproof material (thickness equal to or greater than 14 mils).

Summer Season: Apply 1 tag per animal to control horn flies for 3-4 months, control lice and aid in control of face flies. Apply 2 tags per animal (1 in each ear) for optimum control of horn flies, lice, Gulf Coast ticks and spinose ear ticks for up to 5 months. Two tags per animal also provides substantial reductions of face flies and aids in control of stable flies and house flies. Apply when pests appear.

Winter Season: Apply 1 new tag per animal in late fall to early winter to control biting and sucking lice. Kills biting lice and most sucking lice within 2 weeks. Protects from lice reinfestation for 2-3 months.

Apply new tags in spring for fly and tick control. Replace as necessary. Apply as shown with the Y-TEX 2-piece tagging system. All animals in the herd should be tagged. Calves less than 3 months of age should not be tagged or ear damage may result. To minimize development of insecticide resistance, remove used tags at end of fly and lice seasons and follow Y-TEX’s recommended tag rotation program.
