Directions For Use

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

Summer Season: For control of horn flies for 3-4 months and aid in control of face flies, attach one strip over the button of any two piece identification (ID) tag in late spring. To control horn flies, face flies, lice, Gulf Coast ticks and Spinose ear ticks for 4-5 months, and to aid in control of stable flies, black flies, house flies and small horse flies, apply two strips per animal (1 to each ear) when flies appear in the spring. Apply 2 strips to large bulls for optimum horn fly protection.

Winter Season: For season-long lice control, apply strips in late fall. To control biting lice, shortnosed sucking lice and aid in control of other sucking lice, apply 1 strip per calf or 2 strips per mature animal (1 to each ear).

For use only on ID tags that the application site has completely healed. Preferably use with ID tags that were applied the previous season or earlier. Apply as shown on front panel over the button of any existing 2 piece ID tag, such as the Y-TEX All American® 2 piece ID tag system, using 1, 2, 3, or 4 star tags.

Apply as shown when attaching to male/female combination ID tags or one piece ID tags by folding tag body and placing tag through the “key hole” in strip and sliding the strip up and over the shaft of the tag system. It is not recommended to place the strip on the back of a one piece ID tag.

All animals in the herd should be treated. To minimize development of insecticide resistance, remove used strips at the end of fly and lice seasons, and follow Y-TEX’s recommended insecticide rotation program.

Directions For Application

2 Piece ID Tag on back of ear

Directions For Application

1 piece system or male-female double tag on front of ear
