Feeding Recommendations:

Provide SWEETLIX ClariFly Fly Control Block as a free choice source of salt and minerals for your cattle and horses. When used as directed, it will provide sufficient ClariFly to inhibit fly emergence from the manure of treated animals. This product prevents the development of horn flies, face flies, house flies and stable flies in the manure of treated cattle and horses. 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. Allow free choice to cattle and horses. Cattle should consume an average of 0.8 oz of SWEETLIX ClariFly Fly Control Block per 100 lbs of animal body weight per day which is equivalent to 8 oz. per day for a 1,000-lb cow. Horses should consume an average of 1.2 oz. of this product per 100 lbs of animal body weight per day which is equivalent to 12 oz per day for a 1,000-lb horse.

  1. Assure that cattle and horses are not starved for nutrients prior to feeding this block.
  2. This product contains added copper. Do not feed to sheep and other species that have a low tolerance to supplemental copper. Do not use in association with feeds containing supplemental selenium.
  3. Offer to cattle and horses one SWEETLIX ClariFly Fly Control Block for every 3 to 5 head.
  4. Remove all other self limiting nutritional supplements.
  5. Locate SWEETLIX ClariFly Fly Control Blocks where animals congregate (watering, loafing, shade areas).
  6. Replenish SWEETLIX ClariFly Fly Control Blocks on a regular basis as needed.
  7. If intake of this block is below 0.8 oz. per 100 lbs animal body weight per day for cattle or 1.2 oz. per 100 lbs. animal body weight for horses, increase the number of feeding locations and/or change locations to areas more frequented by animals. If intake is above recommended rates, reverse the above procedure and reduce the number of feeding locations and/or change locations.
  8. Introduction of this product after adult fly infestation is established may require treatment of cattle and horses with supplemental sprays to reduce the adult fly population coming from outside sources.
