I keep coming back to this fly spray!

I've tried almost ALL of them and I keep coming back to REPEL-X emulsifiable fly spray - it is cost-effective (especially if you have more than one horse) and is easy to use and as long as it isn't mixed too strong is not likely to "burn" your horses' skin (I do have one out of three that I need to be careful with). Buying it by the gallon is the most cost-effective and the quart is second best.

Love Repel-x

I love it but thought I had cancelled three bottles since I had already ordered 3 previously......Somehow Chewy misconstrued my intention and now I have 6.....As I said.....I love Repel-x but am a little unhappy as I didn't mean to stock my shelves with only having 3 horses.....

Farnam Repel-X concentrate

It really really works. I mixed it in a gallon milk jug so ready to use when I need it. I am in South Carolina and the bugs are already bad:(. This spray does kill on contact and keeps the bugs away at least for a while.

Great for a quick AM spray

Used Repel products for ever and they have always done good ...No fly Spray product works like they say but with this one i make in a gallon container and fill my sprayer as needed for a quick leg/belly and spine spray ...Its a daily need but cheap enough to do for 3 horses every morning and No problems with skin reactions with the water base and there is no disgusting embedded sand

used for years

This is the only product that does not cause hives on my horses. Been using it for decades. Like that I can mix it at differing dilutions depending of the pest. Found the best price on Chewy. Fast shipping too.

Only Fly Spray I will use

I have used this Fly Spray for Years. It is the only thing that seems to give any relief of the horse Flies. I do mix it a little stronger than recommended and Apply it more often as well when I am home, but it works.

smells like a terrible cleaner

It’s smells like something you would clean your wood floors w and it doesn’t seem to keep flys off my horse at all. I sprayed directly on some flys and nothing happened.

Have used for 20 years

Like any fly spray it’s not very long lasting but I include it in my homemade spray recipe. I think it helps. I don’t like to switch sprays since my mares can react to others.
