Tis the season, maybe a bit early, but here in Southern Indiana, the flies have gotten my horses stamping their feet and shaking their heads.
Our local farm stores all seem to carry the same common brands of spray. I think a few of them are nothing more than fly candy, and none of them seem to be effective after 2-3 hours.
Does anyone have a favorite brand (or home brew) that really works for more than a couple of hours?
