VERY EXPENSIVE AND WORKS GREAT FOR ONE OR TWO SEASONS THEN NOPE! I STARTED USING THE RED BOTTLED ULTRASHIELD AND IT WORKED WELL BUT SEEMED TO MAKE MY HORSES (I HAVE 5 OF THEM), DROWSY AND A BIT LETHARGIC. I WENT BACK TO THE BLACK BOTTLE AND IT WORKED FOR A WHILE BUT THEN NOPE AGAIN. I'M THINKING OF STARTING A FEED THROUGH AGAIN.

Quickly Effective

Best fly spray I've ever used, has never given my sensitive skinned horse any adverse reactions, and does a great job of keeping flies away. I live in south florida

Best fly spray I've ever used, has never given my sensitive skinned horse any adverse reactions, and does a great job of keeping flies away. I live in south florida and our flies can be brutal, I can tell other horses in my barn are uncomfortable and stomping to keep flies away, but my boy is happy and chilling because this fly spray keeps him comfortable :') I apply once a day, after hosing my horse off after my ride. When flies are really bad, I'll apply before my ride too, but that hasn't been necessary lately

It seems to work well.

It smells good as well as works well. I wish it wasn’t so high priced though.

Effective and love the sunscreen

It is effective for flies but doesn’t have the staying power it used to have-or maybe flies are becoming tolerant. Having a true black mate, I appreciate the sunscreen

While I've found no fly spray keeps flies off for days, or even hours, Ultrashield EX has been the most effective. You can see the flies drop off their legs when sprayed. We use it morning and night, along with other fly control measures, and it's my favorite. The added sun protection is a plus.
