If you’re using a mineral form of fly control, like Wind and Rain Storm Fly Control Mineral, consistent intake is key. Calculate consumption to know if cattle are eating enough mineral to control the flies. Aim to hit the target intake listen on your feed tag. Target intake for loose mineral is two or four ounces per head per day if you are using either low salt or complete cattle mineral formula. Mineral tub target intake is six to eight ounces per head per day.
Remember, the active ingredient in Wind and Rain Storm Fly Control Mineral, Altosid IGR only prevents hatching of new flies. It does not control existing flies. If you start using fly control mineral after flies are present, you’ll need other methods to combat adult flies. Work with your veterinarian or animal health supplier to find another method like spray or pour-on.
