This product is intended to be used on horses, ponies, and dogs to control and repel biting and nuisance flying insects. Thoroughly brush the animal’s coat prior to application to remove loose dirt and debris. Turn nozzle to ON position. Apply evenly on entire animal with trigger spray, paying particular attention to legs, shoulders, shanks, neck and ears where flies are most often seen. Do not saturate animal. Brush lightly after application. Do not spray in sensitive areas such as eyes, mouth, nose and genitalia. Do NOT apply on immature animals. Cover eyes of animal when spraying around its face, or apply this product to a towel and wipe onto skin around face of animal. This product will act as a skin emollient as well, but be careful to avoid spraying open wounds or severe skin irritations. If in doubt, test a small area before making full application. Repeat application as needed.

Caution: We recommend good safety practices when using any pesticides, such as avoiding contact with eyes and skin and keeping out of the reach of children and pets. If product gets in eyes, flush with water for at least 15 minutes. If on skin, wash with soap and water. If irritation persists, contact a physician. Sensitivities may occur after using any product on animals. If signs of sensitivity occur, bathe the animal in a mild soap and rinse with large amounts of water. If signs continue, consult a veterinarian immediately.
Allergic reactions to the natural oils in Natures Force have occurred in a small number of horses. If you believe your horse is sensitive to these oils, apply Natures Force to a small area for two consecutive days and observe for any unusual reactions. Discontinue use if a reaction is observed.

Works better than other naturals
I have two horses allergic to the chemical sprays. This one seems to last longer and works better than some of the other natural sprays I have tried. Smells nice too.

Not sure ...
I purchased the Nature’s-Force fly spray looking for a more natural repellent and because of the positive reviews. Unfortunately my horse had a reaction and broke out in large welts which seemed painful after using it. I’m not giving it a bad review as it was very hot the day I used it. I plan to try it again on a cooler day to see if she reacts to it again. She’s never had a reaction to any other fly product or anything else... She is 11. She may just be sensitive to this particular mix of oils, it happens. I can’t attest to how well it repels flies.

Good stuff
One of the best natural fly sprays I've used. Quality sprayer with an effective applicator. This doesn't have the lasting effectiveness of some of the harsher sprays, but it doesn't make my sensitive-skinned gelding even itchier and it has the bonus of smelling good.

Yes for some
I love the smell. As far as does it work, I would say yes. I have three horses I've tried this on. One horse brakes out in hives every summer do to the bugs. He refuses to wear fly spray. If I put it on him he goes and rolls it off. So it doesn't work for him. As far as the other two it works, but one is having a little break out issue. I'm not sure if this from the bugs or spray. I just got her so don't know much about her. Some days it last a couple of hours sometimes longer.

Love product
I love love love product, wish it came in a bigger bottle. With 3 horses am/pm applications I use a bottle a week.I do have it on replenishment, so that helps.

Lasts all day!
I have tried every fly spray on the market, and prefer using more organic sprays. Nothing really has any lasting power, so when this product caught my eye, I decided to try it, thinking at the time I was once again going to be disappointed! WRONG! This not only repels flies, but keeps them away the entire day! I had read about some horses getting welts from this spray, and a few times my horse did exhibit some small welts, but I decided to keep using it as it worked so well! I am glad I stuck with it, as my horse is not sensitive to it anymore! I think the clove oil can cause some minor bumps, but they get over it in 24 hours. I will always buy this product and recommend it because it works!

Best fly spray available. Works great and smells good!
Sharon B on Mar 31, 2018
Killed and repelled flies that were constantly after our horses. Two of our horses are Paints, this product seems to agree with the pink skin on the Paints. Also, does great on our bay-roan Quarter horse.

I'm allergic to pyrethrins and this is the most effective non-pyrethrin containing fly spray I've found.
Jacqueline F on Jun 20, 2017
I am hoping this product will control flies on a horse who is prone to hives from fly sprays

Why did I choose this? IT WORKS!!!
Carol O on Aug 5, 2016
Because it works very well.
Beth T on Jun 9, 2016
I recently purchased two bottles and I have found it works wonderfully keeping flies off my horse. My trainer is pregnant and she tried this as it will not be toxic to her, the baby or our horses. It smells wonderful and works better then other "natural" sprays that we have tried. The price is excellent, also. Since she started using this spray, four others of us have ordered it and are using it with good results.

How long does this fly spray last?
EHorseLover on Apr 2, 2016
BEST ANSWER: Once the bottle is open, I would say for a year. If never been open you could probably keep it for 2 yrs. but you might want to contact the company to get a correct answer. . If you want to know how long it lasts once it is applied to the horse, I would just say one day as it could get washed away from the rain or if they roll it could also get rubbed off . Sweat will also( rinse ) it off .
Can I use this spray on sheep?
Heather R on Jun 27, 2016
BEST ANSWER: The Natures Force in the green bottle is all natural so I don't see why not . You may want to read the ingredients on the label to make sure your sheep will be ok . The horse that I have is allergic to many things but nothing in Naturs's Force bottle . Just make sure to get the green label as Farnum has a variety of sprays .
Is this safe fir cows? Is it safe for pregnant cows?
A shopper on Jul 31, 2016
BEST ANSWER: I only got it for horses and it worked GREAT. Don't know why you couldn't use in a cow.
I'm using it on my dog (lab) the flies are eating him alive this summer in Cali. No one has mentioned dogs. Is it safe for a lab?
Rosie H on Jun 18, 2017
BEST ANSWER: I'm not sure if it would be safe on a lab, I use it on my horses legs only because it makes them break out if sprayed anywhere else. I think if it bothers the horses skin in will bother your dog. They make great organic sprays that are pet safe, search Amazon.
