Farnam Endure Sweat Resistant Fly Spray for Horses 50fl oz bottle - Black

We started using this fly spray last year. Most fly's ignore fly sprays. This one actually seems to work. It doesn't have an obnoxious odor to it either. It also comes in an easy to pour gallon size refill. We will continue to buy this product for fly control on our horses. We have an older grey horse and I sprayed 2 legs with this and 2 legs with another product. At the end of the day the 2 legs with the other product had blood spots from the flies and the legs with this product did not. I marked as an excellent value because it works. There are cheaper products out there but if they don't work it's not a deal.

This is one of the more expensive fly sprays out there but I feel it is worth it - I have not had a single issue is any of our horses having a sensitivity to this spray and it is safe for pregnant mares and foals.

This product is a little pricey, but after trying less expensive sprays, I came back to it. I don't have to use as much product to get a good result. Our trail rides are much more comfortable when I use this fly spray.

I am sensitive to scents, many of which can trigger migraines. This spray is not harshly scented, while still doing a great job to keep the bugs and ticks away.

I have been using Pyranha for several years, and my horses and I thought it smelled really strong, but it worked better than anything in the near price range. I found a good buy on Endure (it had previously been too expensive) and decided to try it. I had bought it a couple of times by the quart and knew it worked. I did not remember it having a strong smell. The smell is definitely not as strong as Pyranha, but it's still pretty strong. I guess if a fly spray is going to be good, it's going to have a strong odor. Overall, I am glad I spent the extra $$ and got it.
