Clarifly Cattle Fly Block, 33 LB.

Provide this block as a free choice source of nutritional
supplementation for your cattle. When used as directed, this block provides sufficient diflubenzuron to prevent fly emergence from the manure of treated cattle. This product prevents the development of horn flies, face flies, house flies, and stable flies in
the manure of treated cattle. Existing adult flies will not be affected. Start feeding this product early in the spring before flies begin to appear and continue feeding throughout the summer and
into the fall until cold weather restricts fly activity.
