I tried one last year with no noticeable difference, but this year I'm using Springtime Bug Off Garlic and seeing a definite difference. I wasn't sure at first, but today was very humid day. When I went out to get my horse, he was hanging out with his best buddy. Both horses are dark bay. They were standing nose to nose. The other horse had flies climbing all over his face. My horse had none. My horse also gets attacked on his belly by no-see-ums. While he is still itchy this year, it's nowhere near the raw belly he had last year. So far all the hair is there for the first time in the 3 years I've had him. It's not a miracle supplement. Flies do still hover around him and some still land. Yesterday one of those nasty green biting ones took a nice chunk out of him. That being said, I'll try anything that gives him any relief from flies, so I'm glad that this stuff works, at least in part. It is only available in powder form, and it STINKS of garlic. If you have a picky eater, you may be out of luck. Otherwise, give it a try.
I am trying this all natural supplement that I got from The Natural Horse. It is basically a top to toe type of supplement. It only has three things in it...rose hips, kelp, and lots and lots of garlic. It reeks of garlic. My BO opened it up the first time and said that it woke her up. Hahaha....but I have noticed a difference. The flies used to just congregate on his face last year. This year, not soo bad. It is giving him some relief and I'll take it. It really isn't that expensive, like 40 bucks. But you only feed about 1/2 to 1 scoop every day and you get a 4lb bucket. It's worth a try. It worked for my baby and that's all that matters.
I still spray when I ride though because he sweats, which attracts the flies. So, I just spray with Flysect Super 7, which is super strong.
