Great fly spray.
I liked this fly spray, I’ve been using it for a week and noticed less flies landing on my horses and less tail swishing after they are sprayed with it. It doesn’t have a super obnoxious odor, seems to last quite awhile and lacks the nasty residue some fly sprays leave. I feel comfortable using around my kids and think it works good for tbh e price.

Great fly spray!
I've bought this fly spray multiple times as it is the only fly spray that seems to be working against all the crazy flies this year! I think it's because the active ingredients are stronger than normal fly sprays. The sprayer is nice because if you squeeze it quickly, you can get a fine mist but if you go slower, you get a thicker consistency that is great for covering legs. Shaking the bottle before application is also really helpful to make sure it sprays well.

Honest review!
Gave this fly spray a try - I like that it’s not oil based and there’s not a strong crazy scent! Smells more like alcohol more than anything! It is quite effective and lasts maybe 2 days or so after application in dry weather. I do not love the sprayer - comes Out too strong and splotchy. Maybe with a different sprayer it’d be better to apply!

It Really works!
This spray is Super effective and a great value because it Works! This has a chemical-type smell, so not as pleasant as a mint or marigold scent but when I saw how well it worked, I didn’t care about the scent. This lasts for days on my horses with 24/7 turn out. I just sprayed again before the farrier came and there were no flies bothering us! I’d absolutely buy this again.

Wonderful fly spray
Can't believe that it's already fly season, but sure enough, it's time for fly spray again. Purchased this and really pleased with the sprayer, it's very heavy duty and dispenses the spray in almost a bit of a foam that really sticks to the horse. I have a princess of a mare that is very picky about fly spray smells but also cannot stand flies on her. This passed with flying colors in both areas! Lasts a good while and keeps the flys off her.

Formula 707 Fly Deny Spray for Horses & Ponies
I use and love 707 products which is why I am saddened to say I cannot write a positive review for the fly spray. It is thick and does not "spray" but rather streams. I changed bottles to my trusty ZEP sprayer and still, I could not get a mist, only a thick stream that made streaks on my horse. You could clearly see where the stream landed and a fly sat right there, never mind the spray! Unfortunately, this is not a purchase that I would repeat.

Doesn’t last long
The flies are horrible where I am and constantly swarming around my horse and I. I have been trying to find a repellent to get them off my horse. I was curious about Formula 707 fly spray and received the opportunity to try it. At first spray I was impressed but as time went on the flies came back. Ultimately it is on par for a basic fly spray and kept fly off for approximately 15 minutes. Will keep searching.

Works as designed
The spray is working great. It's a very warm and unusually dry summer so far this year and flies are abundant. So far this spray is holding up against the onslaught of flies our horses experience. The nozzle on the bottle broke at one point so I had to label another bottle and transfer contents over. Could be a fluke, but perhaps it's a cheap design. Otherwise the product is working great. I love the difference in spray methods.
