Review: Flies die instantly!! - Living in Texas the flies can be terrible and while I do use a fly mask, it seemed other fly sprays would either only work for a bit or only deter some flies. I was almost going to go with a different spray because I thought this was a little pricey but then I decided to give it a go, and I’m so glad I did!! I got this spray the evening before my farrier was scheduled to come out. The next morning while waiting for the farrier I noticed how bad the flies were even that early, so after I groomed my horse, I started spraying him with this fly spray and let me tell you this stuff worked so good that some flies were literally dead on my horse!!!!! By the time I finished spraying there wasn’t a single fly that was alive on him!!! My farrier happened to be running late due to the client before me asking him to do 6 horses instead of 2 that were scheduled. When he finally arrived it was well past noon and I assumed that by that time the fly spray would have probably worn off as most do. NOPE!!! There still wasn’t a single fly on him. I literally couldn’t believe it!!! The listing says it lasts up to 14 days, now I can’t confirm or deny that statement as I generally reapply it atleast once or twice a week after a grooming session but I will say it does last for several days. The bottle itself doesn’t leak, however I’ve order this product multiple times from desertcart and there was one shipment that apparently busted during transport because I received a notification stating my product had been damaged and it would be delayed due to it be reordered. Obviously this isn’t due to the seller but something along transport. This product really works and although pricey, it is worthy every penny.
