Safe for daily use across all horse breeds, it offers a 60-day supply that supports season-long fly reduction when started early and used consistently. Combining SimpliFly with topical sprays and physical barriers creates a comprehensive fly management system, ensuring a more comfortable, healthier environment for your horses. ## Description The most effective way to control flies around horses is to stop them at the source before they ever become adult flies. Left untreated, manure from a single horse can produce thousands of flies in a single day. Farnam SimpliFly Feed-Through Fly Control is a palatable alfalfa-based pellet designed to provide reliable fly control for horses by interrupting the fly life cycle where flies breed. The active ingredient diflubenzuron passes through the horse unabsorbed and deposits in manure, preventing fly larvae from developing into adult flies. Because SimpliFly works in manure rather than on the horse, it provides barn fly control and stable fly reduction without sprays, wipes, or topical treatments. Safe for daily use in all horse breeds and formulated without organophosphates, SimpliFly Feed Thru Fly Control mixes easily into your horse’s regular feed. For best results, begin feeding in early spring before flies appear and continue through summer and fall to support consistent horse fly control in barns, stalls, paddocks, and pastures. For complete fly management, combine feed-through fly control with topical fly sprays, fly masks, and other barn fly control methods to help protect horses throughout fly season. Review: It works - Great item Review: It works! - We love this fly preventative and so does our livestock. No pill to take just some pellets to add to their food ONCE a day. It must taste yummy, because my horses and Donkeys love it. Flys seem to less too.

No pill to take just some pellets to add to their food ONCE a day. It must taste yummy, because my horses and Donkeys love it. Flys seem to less too. I highly recommend SimpliFly ### ⭐⭐⭐⭐⭐ For us a 95% reduction of on farm flies *by D***G on August 13, 2025* Awesome product. 2 weeks after we started using it we noticed the flies were gone. Saves a lot of money and hassle of using fly spray daily that never really worked. For us it reduced our on farm fly population by 95%. It's wonderful be able to be outside around the horses and yard, and don't forget the barn without the flies attacking us all the time. It also pays for itself by not buying gallon after gallon of fly spray. ## Frequently Bought Together - Farnam SimpliFly Feed Through Fly Control for Horses, Breaks the Fly Life Cycle, Pellets, 3.75 Pound Bucket, 60 Day Supply for One Horse - Farnam Repel-X pe Concentrated Fly Spray for Horses, Just Add Water 16 Ounces - Farnam Repel-X Ready-To-Use Fly Spray, Insecticide And Repellent For Horses And Dogs, 32 Fluid Ounces, 1 Quart Bottle With Trigger Sprayer --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/16597782-farnam-simplifly-feed-through-fly-control-daily-supplement-for-horses](https://www.desertcart.tn/products/16597782-farnam-simplifly-feed-through-fly-control-daily-supplement-for-horses) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-31*
