Love this fly spray

This fly spray worked better then more expensive fly sprays. I have never found any fly spray to last for 2 weeks. It still last longer then other brands that claim to work for 2 weeks. It also was more gentle for my horse Major who has sensitive skin.

Does not last 14 days

The product seems to work immediately after putting it on but within 2-3 hours no longer works. It's no different than every other fly spray out there. I'm not sure how they get away with advertising it last 14 days. I followed the directions and really hoped this would work. Not worth it in my opinion.

I purchased this because during the pandemic, we boarders are only allowed to see our horses 4 times a week and I was hoping this 14-day fly spray would help keep my horse comfortable when I couldn't be there at the barn. I sprayed this on my horse and within 2 minutes, the flies were back and all over his legs. I tried spraying him again, and the flies returned again with 2 minutes. If the flies can't stay off my horse for 2 minutes, then they are definitely not going stay off of him for 2 weeks.
