- A: DIRECTIONS FOR USE It is a violation of Federal law to use this product in a manner inconsistent with its labeling. General Instructions: There is no withdrawal period for JustiFly Fly-A-Salt™. Start feeding JustiFly Fly-A-Salt™. in the spring before stable flies begin to emerge and continue use until cold weather marks the end of stable fly season. In some cases, supplemental stable fly control measures may be needed in and around pastures, barns, and feedlots to kill adult stable flies which can breed in other decaying matter or silage in the area, or that migrate in from other locations. Feeding and Management Instructions: Feed this product to cattle only. When used as directed JustiFly Fly-A-Salt™ will provide sufficient diflubenzuron insect growth regulator to prevent the emergence of adult stable flies from manure of treated cattle. Existing adult stable flies will not be affected. Start feeding before stable flies appear, and continue feeding until cold weather marks the end of the fly season. Allow free choice to cattle. Cattle should consume an average of 0.1 oz of JustiFly Fly-A-Salt™ per 100 lbs. of body weight/day, which is equivalent to 1 oz per day per 1,000 lb. animal. 1. Assure cattle are not starved for nutrients in this product prior to feeding this product. 2. Offer 50 lbs. of JustiFly Fly-A-Salt™ for every 20-30 head of cattle. 3. Remove all other self-limiting nutritional supplements while the cattle are being fed JustiFly Fly-A-Salt™ . 4. Replenish JustiFly Fly-A-Salt™ a regular basis as needed. 5. If intake of this product is below 0.1 oz/100 lbs. animal body weight/day, increase the number of feeding locations and/or change location(s) to areas more frequented by cattle. 6. If intake of this product is above 0.1 oz/100 lbs. animal body weight/day, reduce the number of feeding locations and/or change location(s) to areas less frequented by cattle. 7. Introduction of this product after stable fly infestations are established may require treatment of the cattle with an adulticide, if elimination of the adult stable fly populations are required.5 years agoHelpful?
