Rated 5 out of 5 by Have used this for years I have used this fly spray for years. It has no odor and does the job magnificently. This is one of our favorite products. We put it in a pump up sprayer and spray the entire herd with it. June 28, 2011
Rated 5 out of 5 by It works This concentrate is economical and it is very effective. I sometimes add just a little Avon Skin-so-Soft and Citronella oil for extra added effectiveness. June 10, 2011
Rated 4 out of 5 by Super Fly Spray Weve used this fly spray for 2 years now and LOVE it....It protects against flys for days...Especially when sprayed on a wet horse. Its concentrated so its economical and it smells good---We ALWAYS buy this one!!! May 8, 2011
Rated 4 out of 5 by Used in a mister We've been using it for about 2 years. We put one gallon with 49 gallons of water and use it as a mosquito misting system. We live near water and wet lands and found this helps keep the mosquitos away, sprayed twice a day with a misting system. September 26, 2010
Rated 5 out of 5 by Effective & Economical Product The price of a gallon of this product is the same as 3 pre-mixed brand named fly sprays. I can mix up over 120 count of 32 oz.bottles of custom made fly spray. I use the 4 oz./gallon concentration and add 45 SPF baby sunscreen (like in Ultrashield). It smells nice and works great.

I use a lot of fly spray with 3 horses in "buggy" Florida. This seemed a good value.

can one apply permethrin 10% as a pour on on the back line right out of the container on horses gordon ross ????
Ross g on Sep 18, 2014
Best Answer: HI: I personally wouldn't do that... this is pretty potent stuff and i'm sure they have you dilute it for a reason, it would be like pouring it on yourself at full strength... it isn't like dog medicine where it absorbs into the skin. i use it at the recommended ratio and it seems to work. i do have to reapply for the first couple uses and then after that you can slow down with it and seems to be less and less flies. We have 8 horses so it's well worth it. Seems to go a long ways too.

Is this safe to use on gestating and lactating mares?
Audrey on Mar 25, 2015
Best Answer: I was attempting a "short-cut" for the answer to my question on product use. I'm sure the label will provide the necessary information and if not, I will make an official inquiry with the manufacturer before using it on gestating and/or lactating mares, and nursing foals! Thank you, Susan, for trying to assist.
