Because this spray is water resistant it is the perfect choice for horses who are turned out and those who are in hard work. This fly spray repels and provides quick knockdown for a wide variety of bug species including mosquitoes and gnats. Up to 14 days of bug protection means you will apply less often making Opti-Force® Fly Spray an effective and economical choice for your bug battle.

Hassle-Free Returns

SmartPak Returns

We put our products to the test in our barns and on our horses, so we're confident that you'll be thrilled with your purchase. However, we know that life in the barn can sometimes be unpredictable. That's why we've created a stress-free return policy. If you purchase an item and it doesn't meet your expectations, we want to know about it, take care of you and give you your money back.

Free Return Shipping on all Sized Items

As riders and online shoppers, we know it can be tough to buy a new bridle or pair of boots without trying them on. That's why we moved the fitting room to your living room (or barn)! From breeches to blankets, if you or your horse can try it on, you can return it, free! Just use the pre-paid return label included in your order within 60 days from the purchase date. And of course, please make sure the item is in like-new condition with original packaging (we said 'fitting room', not 'war room'!).

The Fine Print

We love our products and we're happy to take them back - even custom items. We'll happily take back everything from engraved halters to personalized jackets - even embroidered blankets that have been worn (minus the manure, please). But there are a few things we have to restrict returns on (silly federal regulations).

Undergarments
Health regulations require that undergarments (including bras) need to be in new condition (tags and packages intact) in order to be returned. (Even if it wasn't required, do you really want to shop from a store that takes back used undergarments?!)

Saddles
As riders, we know what a big investment a saddle is. That's why we're proud to offer the best Test Ride program in the business. You can keep our Test Ride saddles risk-free for five days, to really make sure you like the fit and the feel. We know that to truly try a saddle, you have to really ride in it. So go ahead and girth it up. Forget about wrapping your stirrup leathers. Try it with or without a saddle pad. Basically, treat it like you already bought it, so you can make sure you really want to. Because when you buy a saddle from us, we want to make sure you love it. Of course, we want our other customers to love their new saddles, too.
That's why we have a Test Ride option for each saddle we carry - so that all of the other saddles can stay in pristine condition, waiting for their new owners. For this reason, if you purchase a saddle outside the Test Ride program, it's still eligible for return, but must be free from any marks or damage.

So that's it. Seriously. Those are all of our "rules." Well, except the most important one - treating our customers the way we want to be treated. So if you have any questions or if there is anything we can do, please call us at 1-800-461-8898 or email CustomerCare@SmartPak.com. We are always happy to help.

Instructions for Use:
DIRECTIONS FOR USE:
Shake well before using. Avoid contact with eyes or mucous membranes. Harmful if swallowed. Avoid contamination of food.
To protect horses and ponies from Horse Flies, House Flies, Stable Flies, Face Flies, Horn Flies, Deer Flies, Gnats, Mosquitoes (Culex spp.): Thoroughly brush the horse’s coat prior to application to remove loose dirt and debris. For dirty horses, shampoo and rinse thoroughly. Wait until the coat is completely dry before applying this product. Opti-Force™ is sweat-and weather-resistant, so it keeps working when the horse sweats, and after rainfall.

Spray or Wipe Application:
Application should be liberal for best results. For horse’s face, always apply as a wipe using a piece of clean, absorbent cloth, toweling (Turkish) or sponge. Avoid getting spray into horse’s eyes, nose or mouth.Wear rubber glove or mitt when applying as a wipe. Spray or wipe horse’s entire body while brushing against the lay of the coat to insure adequate coverage.
Reapply every 14 days for fly control normal conditions for initial applications. As protection builds, reapply every 14-17 days. Reapply every 5 to 7 days for mosquito repellency. Also, reapply each time animal is washed thoroughly, particularly if with shampoo or soap.
