Is the gallon a concentrate? If so, what is the mix ratio?
Answer by ChewyJun 18, 2022
The gallon is not a concentrate, it is a larger ready-to-use formula, it can be used as a refill for the spray bottle.

Can this be used on dogs?

This repellent spray is not designed for dogs, only horses.

It stays on a few days and great on trail rides to keep the fly's off. Nothing can completely keep the fly's away sadly!

Great product

This is a really good product. Under normal conditions it lasts at least a day, and in winter, for mosquitoes and such, a couple of days. My horses who are more sensitive to some products handle this one fine. Pricing is good, too! Regarding packaging, it would help if tape was placed around the cap. The product leaked in the box. The box itself had a lot of packing material in it but being a liquid, the product leaked. No one likes to lose expensive product... Thanks!

The only repellent!

The best out there! Very little smell and nothing like all the others. I have 1 horse that HATES the smell of most sprays and won't allow me to use other sprays on him but had no problem with this. I have another horse with SEVERE allergies to most Flys and bugs and this spray has completely changed her quality of life.

This Year's Winner

Every year I end up using a different fly spray, whichever one seems to be working the best. Endure is working the best this year. It has a great smell to it. But, as EVERY horse owner knows, the statement on the label of this product and other brands as well, that it protects for 14 days is a total joke.

My go to fly spray

Been using Endure for years and it is very effective repelling flies. I keep a bottle in my tackroom and in my trailer.

Farnam Endure Fly Spray

This spray works better than any other sprays I've used in the past and I've used just about every brand out there natural and chemical. It doesn't seem to be sweat resistant or last as long as it says it does. I still have to apply 2x a day during fly season. So 4 stars for being good but not quite as advertised.

Great fly repellent

I have been using Endure for years. It works well and lasts longer than others, although it doesn't smell as good as some.

Excellent product

Like most long time horse owners, I have been "disappointed" by every fly spray I have ever used, in the sense that none of them live up to the advertised "promises". No this spray doesn't last 14 days. However, my horse has decent protection if I use every few days rather than every day. It IS waterproof, important since my horse goes in and out of his stall at will. And, it is competitively priced. I rated it 5 stars because I am more satisfied with this brand than with any other I have used, regardless of price. And Chewy's lighting shipping is always a plus!

Better than other flysprays

While it doesn't last 14 days, it does last more than one and that's good enough for me. My horse, who hated being sprayed when I first got him, will come over when he sees me pick up the spray bottle now as he associates relief from biting insects with it. The scent is pleasant enough, too.
