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.
