Altosid in the lick tubs we give to the cows and also 30cc of Ivermectrin pour on as each cow calves in the spring. Never going to totally get rid of the flies but that has seemed to be our "go to" strategy for flies and seems to work well. We have a river going through our pasture with lots of marshy areas also so I feel your pain
