total waste of money; get UltraShield EX

2 months ago
I wondered why this wasn't working. It only has pyrethrin, which degrades in sunlight. You need a spray combo with permethrin. Also, the label says 7:1 dilution but did not explain that for HORSE FLIES you need a 4:1 dilution.

No, I do not recommend this product.

Great product for relentless flys!

The packaging is great quality! It kept the flys away from the horses very well. It’s easy to store away I’ll be reusing this product moving forward, I love it!

Gets the job done with a harsh smell

10 months ago
I received this product for free from Influenster. This fly repellent is a solid, budget-friendly option for fly control, especially for those with multiple horses or sizable areas to cover. The concentrate mixes with water to spray on horses, around stalls, or in barns, and it claims to kill and repel various flies plus ticks, gnats, and mosquitoes.

Great value

10 months ago
Repel-X has been a game changer for me and my horse, especially on trail rides where bugs can usually make things pretty miserable. I really like that it’s a concentrate because it feels like good value for the money, one jug lasts a long time once mixed. The packaging is solid and easy to pour from, which makes mixing without spilling way easier. It holds up well even when my horse sweats, so I don’t feel like I have to constantly reapply. The scent is definitely that classic fly spray smell, but it’s not overwhelming and doesn’t stick to my clothes the way some others do. Most importantly, it actually works, flies, gnats, and mosquitoes leave us alone so we can actually enjoy our rides. For me, it’s been a reliable and effective spray that I’ll keep buying.
