This is one of the fly sprays I use the most. It seems to work the longest out of similar products. I don't see quite the overall reduction being the best, but it gets the majority of the flies off for the longest.

Pros: Works for several days

Cons: a few

This is one of the best products I have found for keeping flies off my horses. I don't know what else to say. It works.

Pros: Good for 17 days

Cons: The spray pump could be made better, it drips.

I have tried everything...........Endure the the best fly spray ever. Maybe Ultrahield has improved. I will try it again, only cause endure is expensive. I have 15 horses and it mounts up $$$.

Pros: none

Cons: none

This stuff works great - knocks flies down when you spray them. Easy to use and apply. Can be purchased at Tractor Supply and most equine supply stores.

Pros: Quick to kill flies.

Cons: n/a

I use this spray alot. It may cost a little more than some, but it actually works...and I like the UV protection too!!!

Pros: wonderful product

Cons: Price
