About Farnam Repel-X Insecticide & Repellent Ready-to-Use Spray

Multipurpose Defense

Since 1957, Repel-X Insecticide & Repellent has been helping people protect horses, dogs, and their premises from flies, mosquitoes, ticks, fleas, and more. The dependable, water-based formula ensures a non-oily application for both animals and surfaces. Use it as either a spray or a wipe—it’s a multipurpose pest defense you can rely on.

Create a No-Fly Zone

Farnam’s No Fly Zone horse products provide comprehensive pest protection. The three-step approach includes the SuperMask II horse fly mask to BLOCK insects from your horse’s face, Endure Sweat-proof Spray to REPEL pests, and SimpliFly Feed-Thru Fly Control to REDUCE flies. Together, they help keep insects away from your horse’s face and body, act as a safeguard against six types of flies, gnats, mosquitoes, lice, and deer ticks, and prevent the development of house and stable flies. 

Dependable Protection

Fighting flies requires different solutions for different challenges. That’s why you’ll want to add Repel-X Insecticide & Repellent to your arsenal. This cost-effective option will help protect your horses, dogs, and their premises, all in one bottle.

Easy Application

Applying Repel-X Insecticide & Repellent is simple and easy. Start by removing any excess dirt from the animal, then apply directly as a light spray or wipe it on, avoiding eyes and other sensitive areas. If using as a surface or space spray, remove animals from the area before applying. Use a good sprayer to deliver a coarse, wet spray on targeted surfaces. Reapply every day for best results, and always refer to package safety recommendations before use.

I seen someone says they used for their goats. So this is safe for mini fainters? 3 months old?
Answer by ChewyJun 04, 2020
Farnam Repel-X Horse Insecticide & Repellent is EPA registered for horses and dogs. It is not recommended using on goats. It's recommended to speak with your vet to find which treatment would be suitable for goats.

is it oil base or water base?
Answer by ChewyApr 26, 2019
This product is water-based.

Is this safe to use in combination with a topical treatment?
Answer by ChewyApr 02, 2019
Full-strength preventatives are intended to be used alone. We encourage speaking with your vet before combining pest preventatives for the safest opinion.

the products above are they ok to use on dogs as well
Answer by ChewyMay 23, 2018
This product is also gentle enough for dogs.

Relief in a bottle

Repel-X has brought much needed relief to my horse and two donkeys. , I do need to apply it daily, but for that period of time, every body is comfortable. I would recommend.

My poor dogs have been terrorized worse than ever this summer by flies, and I tried a dozen other options before I found this spray. One use of this made an instant improvement. I’ve had to reapply 3 times over the course of 2 weeks and they’re almost completely gone. I combined this with a cream also from Chewy and my pups ears have finally healed up completely and hair is regrowing on the tips. Hallelujah. If you’ve got flies, this spray is going to be your best friend.

Great Product

We bought this for our dog who loves to be outside. The flies won't stay off of his ears! This is magic and doesn't bother him in the least when we spray him. No more bites on his ears!!

Kills mosquitos on contact

This is a great product, but if it rains several days in a row (even a small amount), the spray washes off and the pests go right back to the horses. Our stables have an overpopulation of mosquitos, and I've found that we have to apply it once a day. If we skip a day the horses have fly and mosquito issues all over again because it doesn't seem to repel them longer than that.

Works Great!!

This spray works great! My 4 boys aren't bothered at all by the flies once I spray them. The price is better than the chain farm supply store around the corner! I can't recommend this enough!

Works and smells good

This stuff works. Buy the condensed one, it's a better deal. The 32oz bottles don't last long.

My go to product

I have used RepelX for years. I’ve tried other brands, and they didn’t work any better! So, I always go back to my tried and true!

Worked great

Bought to use for lice on my goats and also as a fly repellent for my horses. Worked great- after combing the spray into my goats hair the lice was gone after 1 application. Seems to be working well for the flies as well so far.
