*In the majority of cases, all of the important parasites can be satisfactorily controlled with only two treatments a year. Parasite burdens vary by the horse. It is estimated that 20% of horses harbor 80% of the worms. Therefore, horses with elevated FECs (> 200 eggs per gram) require additional treatments throughout the year to limit shedding.
