    the flys lay their eggs in the fresh cow pies. ideally you would be able to move the cows to new pasture before they hatch in less than a week, or have chickens come up behind the cows to scratch apart the piles and eat the larvae(by day 3 to 4), or both…

    a pour-on will get the flys on the cows now, but in my experience only last about 2 weeks and needs re-applied. (it is also bad for the dung beetles- but so are the chickens 🙂
