    Rated 5 out of 5 by from Waste Less! I live next to the woods, and ticks are a big problem for my 31 yr. old mare. She lays down a lot because of arthritis, and they just attack her underside! When I spray her down, the repellent really does the job. Seems to be keeping ticks off of her for a full month from each spraying.

    Rated 5 out of 5 by from Works great I've used this for a few years now, I do apply every morning though but seems to last all day. Works great for gnats & mosquitoes too. Use in well ventilated areas as you do NOT want to breath this stuff! One of my horses swells up bad from gnats bites, this produce totally eliminates that problem.

    Rated 5 out of 5 by from Great Pest Control Pyranha has always been my one and only choice for fly control since it is the only fly control I've used that has actually worked. The aerosol is no different. Easy to apply to both horses and buildings. I have one guy who is super sensitive to flies and as long as I apply it regularly, he has no issues. My other two despise the spray bottle but tolerate the aerosol spray pretty well. Overall, couldn't be happier with this product.

    Rated 5 out of 5 by from Amazing The location of my horse is swampy and muggy. The flies are horrible. When I got my horse his legs were covered in blood and flies. After a bath and a coat of this stuff he was perfect. Now I spray him and the run in once a week.

    Rated 5 out of 5 by from Absolutely the BEST fly spray! This is the only fly spray I'll use now. It stays well even in our crazy weather and wind. It works like a charm on all types of flies. I recommend it to everyone. The aerosol ensures more even coverage than a traditional sprayer, and it lasts longer because less product gets wasted.

    Rated 4 out of 5 by from Works well quickly, love the aerosol I am happy with the Pyranha Aerosol Fly Spray. I love the aerosol as opposed to spray. My horses stood still for application - much better than with the regular spray. The fly spray worked immediately while grooming which made it much more comfortable for both of us. The application lasted through my ride and while taking off tack. I'm not sure how much longer it lasted because I did need to apply the next day to start the routine all over again. The scent is pleasant enough and it is not too oily. I have already purchased another can :)

    Rated 5 out of 5 by from amazing stuff This stuff is pretty amazing. my horse doesn't like the aerosol so I use an intermittent action like I would with the regular pump sprayer. Seems to be worth the price. THe flys are bad this year.

    Rated 5 out of 5 by from Pyranha Aerosol Fly Spray A friend on mine had some of this fly spray at a horse show and let me try it. That was over a year ago and I have been a true believer in this stuff. It really works great and keeps the flies under control while out on the trail. It has a very strong smell however so I take a break between spraying my horse and only do one side of my horse at a time.

    Rated 3 out of 5 by from Has its good points and bad... First the good points...the spray really seems to work against our vicious flies and it leaves a nice shine. It is easy to applyBad points...the spray is almost impossible to not breath in (person or horse) and just a slight breeze will misdirect it. Not sure how much gets on the horse compared to how much gets lost in the air.

    Rated 5 out of 5 by from Best Fly Repellant Ever! I've been using this stuff for years and it's the only thing that works. I've tried the different natural sprays and even other brands, but nothing works as well and as long as this. Not only does it repel the flies, but it also leaves my horse with a shine! HIGHLY recommend!

    Rated 5 out of 5 by from Pyranha Aerosol Awesome product, not as oily as the spray bottle, does a great job repelling flies. Better than any other product on the market. Has the highest amt of pyranthians.

    Rated 5 out of 5 by from Flymageddon I'd resisted buying non-natural fly-sprays for ages. But this summer, the flies have been epic. No spray, not even my trusty Deo Lotion, could stop them from harassing my mare. My trainer suggested Pyranha and swore the aerosol was better than the spray-bottle. This made me cringe. However, my horse was desperate for relief so I went all in and bought a can.And you know what? The Pyranha kicks butt and takes names. I ride every other day, and use it following her post-ride hose down (as a compromise I use the Deo for my ride, especially on trails). This spray lasts well between rides and, while it's a little stinky, pretty much decimates flies on contact. Admittedly, this is a little troubling. But, seeing my horse relaxing/having fun in her paddock instead of stomping around, frantically swishing her tail is a wonderful thing!This stuff is great to use as the big guns and I don't seem to go through it as quickly as other sprays I reserved for bad fly days.

    Rated 5 out of 5 by from Best Fly Spray Available I was so excited to see that SmartPak has started to carry this product. It has been a staple in my barn for years. I love the Pyranha Wipe and Spray, however the Aeorsol is even better. It allows for an even application, lasts longer and most importantly- keeps the flies away from my mare. Love this product!
