For optimum control and to minimize development of insect resistance, use two tags per animal (one in each ear). All animals in the herd should be tagged. Apply when flies first appear in spring. Replace as necessary. Apply with ALLFLEX Tagging System. Tags remain effective up to 5 months. Remove tags in fall.
Continual exposure of Horn flies to a single class of insecticide (eg, pyrethroids or organophosphates) may lead to the development of resistance to that class of insecticide. In order to reduce the possibility of Horn flies developing resistance, it is important to rotate the class of insecticide used and/or the method of Horn fly control on a seasonal basis.
