Product Summary:

Pyranha SprayMaster

The SprayMaster is a 1/2 horsepower electric motor-driven pump controlled by a solid state electronic timer that is programmed to dispense an insecticide formulation in the form of a very fine mist at specific intervals through special spray nozzles. The result is a state-of-the-art, hassle-free solution to control harmful flying and biting insects in and around horse barns. The system comes with a 55-gallon Polyethylene drum, motor pump, automatic timer, pressure gauge, by-pass valve, connections, and instructions, and is easy to install with basic tools.

Available in 30-gallon and 55-gallon sizes, 1-10 HP Concentrated Insecticide Refills are premium formulations that have set the bar for effective automatic flying insect control in horse barns. Developed over 30 years ago using the highest quality pyrethroids, they provide quick knockdown and long-lasting protection against a broad range of harmful biting insects, including horn flies, deer flies, fruit flies, black flies, stable flies, bot flies, face flies, midges, fleas, mosquitoes, and gnats.

Where to buy spray nozzles for a spray system in a barn?
Maria e on Jun 2, 2015
BEST ANSWER: I found at least two sites on the web that carry the nozzles for the Pyranha system...
Huberth Farm System or on the web and Jeffers at on the web...
I would try McMaster-Carr too. They are very proud of these nozzles by the listed price. I would experiment with mister nozzles if they could be adapted to the tubing system.
Hope this helps - Walter
Can I use this in my horses outside paddock. He has a lot of flys under his shelter where he is fed? How near if far does it need to be from his feeding area
Priscilla R on Apr 30, 2017
BEST ANSWER: I LOVE our SprayMaster. I purchased it two years ago and have had no problem with it. We have 8 horses on the property and that equates to alot of flys. It knocked them to down to almost no flies. I have the spray nozzles about 12 feet from the feeders.
How often do we need concentrate?
A shopper on May 15, 2016
BEST ANSWER: It depends how often you set the timer to go off. I have mine going off every 2 hours at night when the horses are in their stalls. Less often during the day. Also what time of the year. Also it depends on what duration you set it to spray. I set it for 30 to 45 seconds. Again depending on how bad the fly problem is at that time of the year. That is easily regulated by the switch next to the clock. I have it shipped one a month but I usually get ahead of it an have extra by the end of the fly season at which time I suspend the shipments until the next year. It just takes some trial and error the first year. Once a month might be a good starting point.
is this product organic?
A shopper on Mar 7, 2014
BEST ANSWER: What do you mean by organic? I believe it's derived from citronella oil.
We also have ducks. Is this system safe around them?
Christine P on Mar 18, 2019
BEST ANSWER: I don't have ducks, but it is my understanding that it is safe around pets and people. Might want to check with Pyranha to be double sure. Good luck!
Whee do I get tubing, nozzles and concentrate?
A shopper on Jun 5, 2014
BEST ANSWER: I have a 33 gal barrel but i have found over the years that if i buy the 55 gal and split it in half it works fine and saves a bunch of money. I have a six horse barn and i have 8 sprayers and i have never had a problem in 9 years. we spray twice in am once in early afternoon and again twice in evening.
What is the formulation difference between 1-10 HPS and 1-10 HP?
How is this formulation different from the 1 gal jugs?
GRANT K on May 10, 2016
BEST ANSWER: The refill for the 55 gallon sprayer or for the 30 gallon sprayer is very concentrated as it is for a
premise sprayer. This is the system that is installed in a barn. The 1 gallon jugs hold the concentrate you mix with water to spray directly on your horse.
Can this system be used outside near standing water?
A shopper on Feb 24, 2016
BEST ANSWER: i would say yes i have use the product myself in the barn but i would say it really work will kills any fly that it touch inside or outside
im interested in the 30 gallon refill for $139..Is this the system including the pump, drum, pressure gauge as stated in the item description?
t m on Mar 17, 2014
BEST ANSWER: I believe it is just the refill. Systems are much more expensive than 139 bucks.
