We don't feed this to all of the 18 horses on the place, but the ones who get it (ones that have sensitivities to bug bites) have fewer bugs annoying them than the other horses. One horse who refused to eat garlic, loves the Bug Check. Some were suspicious at first but grew to like it.
I have been using this product for about 3 months now and the results are great. It takes about 2 weeks the see results. the difference in the amount of bugs at my property compared to my friends that lives about 1/4 mile away is amazing. I have a horse with very sensitive skin and since I have been using this product he is fine this summer with minimal bites. I live in Florida so there is nothing that will get all those pest but this is a great product.. Gives a shiny coat as well
