Happy Jack Onex Wound Dressing was formulated to repel Habronema flies from open sores and wounds on dogs and horses. Habronema flies lay eggs in the wounds of animals which leads to infection and enlargement of the affected area. Onex repels the adult flies and kills the hatching larvae which allows the skin to heal. Happy Jack Onex Wound Dressing is also effective against house, stable, face and horn flies. Contains Pyrethrins.
