With LONGRANGE® (eprinomectin), you can see the results of season-long parasite control.

Conventional dewormers last only 14 to 42 days. That’s not long enough to protect cattle the whole season. As soon as those dewormers wear off, parasites are waiting to reinfect cattle. Only LONGRANGE delivers up to 150 days of parasite control in a single treatment.1,21 - Dependent upon parasite species, as referenced in FOI summary and LONGRANGE product label.2 - LONGRANGE product label. And season-long parasite control can have a big impact on your bottom line.

“Anytime you can have a product that can help break the parasite life cycle you are actually given an opportunity to clean up your pasture because all those infected larvae that the cattle ingest are killed and they never have the opportunity to turn into egg laying adults.” “In the past, to get the same longevity that LONGRANGE has, you would have had to run cattle through the chute at least three or four times. That’s just too labor-intensive; there is too much opportunity for animals to get hurt, and it’s too hard to do that. This product is going to be a game-changer for me.”
