    "Essential for the barn "

    Used this for many years on many species of animals, recommended by my vet, works wonders for those needing it and I always do preventative for those in contact just in case. Fast, efficient almost instant results. Jeffers is by far the best price and fast shipping, packaged really well, worth the exchange rate and shipping costs.
