Use every day
This is an effective, short acting repellent that has a fresh, lightly herbal scent. I use it daily and have been pleased with the results. Will definitely re-order.
Ashley Chalker –
Nice concept
I bought because it was all natural. Product does work but only for a short while. A light spray will keep the flies away for maybe 5-10 minutes and then I have to spray.
Mark Lenz –
Works for this runner
I use this mostly when running in Wisconsin – where dear flies are terrible. I spray my hat with it, then a light spray on my arms and legs, and the flies stay away. We’ve also sprayed our dogs with excellent results, but as soon as they jump in the lake it washes off.
Andrea Dillon –
Doesn’t work
I bought this to keep flies away from my porch area. They seem to actually love it. They fly into it when it lands on surfaces and hang around the bottle. Don’t waste your money.

Works great! Smells good too!
I use this on my horse and it works just as well as the other toxic stuff…just not toxic. It has an interesting smell of citronella and other herbs. It works instantly! Don’t know how long it lasts because I keep my horse in a stable, but I spray him before and after a ride and the flies instantly go away. I recommend this if you want something that works and isn’t toxic.
N.S. –
Works well
Works well, Smells nice, not full of chemicals I canât pronounce, horses seem happy and Iâm happy.

Great Stuff!
Not only does this stuff smell good, it works really well too! I love the fact that it doesn’t have any toxic chemicals in it but works just as good (if not better) than the stuff that does.
