worming your horse properly is as important as growing your child. Ivermectin kills most worms but does not kill eggs (only hatches them). If you follow up with Bimectin or Exodus on the 18th day after worming with Ivermec you will kill the new worms that hatched (all of them) and there will be no more eggs in there to hatch. Follow that up 30 days later with your 3rd wormer and until the weather changes you should be good. Don't forget to get their teeth floated by a reliable toothman (most always not a vet) give plenty of hay and your horse should make it thru with bells on
I just wanted to say I think this is a great idea and hope Jeffers keep this. I bought this kit for my horses and have had fecal checks and my Vet says no worms. Great kit just like it is but probably need different kits for those who would like more to choose from.
It is very convenient and I have bought several kits over the years but also added one or two more wormers with different ingredients. Can only agree with the other reviews and hopefully Jeffers comes out with another kit.
