    The Tribute® Fly Control Block helps prevent the emergence of horn flies, house flies, face flies and stable flies from the manure of treated horses. The fly control ingredient in this block is ClariFly® (diflubenzuron), which is designed to pass through the horse and works by stopping the development of immature flies in manure (existing adult flies are not affected). The Tribute® Fly Control Block is safe for all horses, though should not be used with any other feed-through fly control supplements.


    • Added fly control helps prevent the development of flies in manure.
    • Contains added vitamins and minerals.
    • Safe for all classes of horses.

    Feeding Instructions

    Provide this block as a free choice source of nutritional supplementation for your horse. When used as directed, this block will provide sufficient diflubenzuron to prevent fly emergence from the manure of treated horses. Start feeding this product early in the spring – 30 days before flies begin to appear – and continue feeding throughout the summer and into the fall until cold weather restricts fly activity. If flies have already emerged, feed 6 weeks to gain full effectiveness.

    *This is a standalone fly control supplement. Do not combine with Essential K® with Fly Control or any other feed-through fly control supplement.
