Can't believe that it's already fly season, but sure enough, it's time for fly spray again. Purchased this and really pleased with the sprayer, it's very heavy duty and dispenses the spray in almost a bit of a foam that really sticks to the horse. I have a princess of a mare that is very picky about fly spray smells but also cannot stand flies on her. This passed with flying colors in both areas! Lasts a good while and keeps the flys off her.

This fly spray seems to work fine and does not have a strong chemical smell. I would give it 5 stars were it not for the fact that it is too thick a liquid to actually spray. It comes out in a stream of white liquid. I thought the problem might be the sprayer. But when I replaced it with a sprayer from a different brand that I know properly sprays, I once again got just a line of fly spray rather than a mist. This reduces the effectiveness of the fly spray, since the horse's coat isn't covered. I just end up with lines of fly spray on his legs and body.

Oh, will you look at the time... it’s fly o’clock! With fly season on the horizon, I decided it was time to retire my underperforming bargain spray and bring in the big guns. Formula 707 Fly Deny is made by a trusted brand and powered by Cypermethrin (a step up from the usual Permethrin), and this spray means business. The nozzle feels sturdy, the scent is surprisingly mild and not at all overpowering, and so far it’s holding up well! It’s early days, but I’m optimistic this will be a staple in our summer fly-fighting toolkit.

It’s not fly season yet where I live, but I believe this 707 fly repellent to be one of the better products on the market.It should be fine for light skinned or sensitive horses.The sprayer is more heavy duty than many of the others. This one smells good. It’s a large bottle and a good value for the price.
