Only product that works well with the flies
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

The Very Best Fly Spray on the Market
Angelina B on Feb 27, 2018
I have used this product for several years on my horses. The product does offer several days of protection and it seems effective. I purchase it by the gallon and refill my smaller bottles as a cost effective means to fly control.
Teresa B on Feb 27, 2018
Endure is the only spray I have used that is effective on Nosium gnats.
Deborah R on Jan 5, 2018
Have used it for years. Great for flies, mosquitos and ticks. One application lasts for 10 - 14 days in the summer even with strenuous rides.
Marianne B on Jan 2, 2018
Works best of all fly sprays I have tried. Better pricing than local purchase even with shipping cost.

There was a scientific study done at University of Tennessee showing that this is the most effective fly spray, so I have stuck with this product for years
Krystal E on Jul 25, 2017

donna g on Jul 7, 2017
Works well but no where near what they claim... good for a 4 hr trail ride... beyond that ... nay.
Glenn P on Jul 5, 2017
Seems to work pretty well on my horses. Expensive at local stores so bought a bulk bottle to save money.
Aimee S on Jul 2, 2017
used it for years. only product that really works.
Beth N on Jun 29, 2017
This seems to be one of the better fly sprays
Patricia J on Jun 25, 2017
works great, doesn't have to be applied every day, stays on even when my horse is sweating. Most of all your price is better than anyone else's.
Liz R on Jun 19, 2017
Trying something new, was recommended by thesis project of a friend.
Deborah K on Jun 19, 2017
Works, hate the black bottle cause it will get ugly in the sun but product is good. Farman....change to a white container! or at least light color.
Carla K on Jun 19, 2017
I have used this product for years...it withstands and works well through sweat and mud. Horseshowing it is a must...I would definitely recommend this product.
Jodi F on Jun 18, 2017
Endure fly spray has proven to be an effective product. I have used other sprays that seemed to have little effect on these SC insects, but Endure just keeps doing it's job. Yes, it is expensive, but it is worth the price.
Robert G on Jun 12, 2017
I like the Farnam Endure fly spray because it lasts longer then other fly sprays

Is this product safe for dogs and is it ok for kids to be around the dog while having this product on him?
Sarah F on Jul 7, 2016
BEST ANSWER: Horses skin is as sensitive as a baby's. I often use it on myself if i don't have something right on hand for me. I have had no adverse effects but i'm also not allergic to anything. I hope this helps.
Shipping costs for the gallon size?
Tina B on Mar 27, 2016
BEST ANSWER: Standard Economy shipping starts at $6.99
If I buy 4 Gallons, do I also get 4 roll on free?
A shopper on Mar 23, 2016
