I have a mare who hates to go out when there are insects bothering her. She will stomp, pace and run the fence line like a crazy horse. I was told by a friend who is an experienced horse woman that this is the best fly spray...I hope it works!!
Karen L on Apr 13, 2019
Love this product! Have used it for years. Stays effective for days and very good for all types of biting insects.

This is the only fly repellent I will use and have used for years. It works as said and does last for days once you start using it.
victoria g on Mar 5, 2019
It works...and stays on
Richard J on Feb 14, 2019
This is the best product for the Florida bug situation. It works on flies, mosquitos and midges. I started using it when I had a horse that had midge allergies at the suggestion of Univ of FL vets and regular spraying helped keep him comfortable. I highly recommend it.
Laurel F on Feb 4, 2019
want a fly spray that will last in hot weather
Klysta P on Jan 30, 2019
Only product that works in central Florida.
Julie P. on Jan 28, 2019
I have tried every spray out there and this one for me is the best.
Christine G on Jan 27, 2019
As a farrier, I use only what works well and this lasts for a long time with no blistering the horse's skin.
Angelina B on Jan 18, 2019
My horses eyes are very allergic to flies. Rolling on some of this keeps them away while we ride. Its more convenient that wiping on fly spray with a rag or mitt. A little bottle lasts a long time.
Sharon G on Dec 26, 2018

Beverly P on Sep 3, 2018
I have found that this works best at protecting my horse. Doesn't last as long as advertised, but keeps the bugs away and that is what is important.
Kimberly H on Sep 1, 2018
It works extremely well!
mary s on Aug 25, 2018
Most fly sprays claim 14 days effectiveness. This is not true for any including this one,however Endure is a solid ten day treatment. Non irritating as well

Does rinsing your horse after riding wash this spray off?
A shopper on Apr 29, 2019
Is this product safe for dogs and is it ok for kids to be around the dog while having this product on him?
