Farnam SimpliFly Feed-Through Fly Control Pellets for Horses – 160-Day Supply | EPA-Approved

Targeted, source-focused fly control for horses

Farnam SimpliFly is a palatable alfalfa-based pellet designed to reduce flies by interrupting the breeding cycle at the source — the manure. The active ingredient, diflubenzuron, passes through the horse unabsorbed and deposits in manure, helping to prevent fly larvae from maturing into adults. This approach minimizes reliance on sprays or topical products and supports barn-wide fly management without disrupting daily routines.

Key benefits in daily use include a consistent, scent-free way to support fly control within stalls, paddocks, and pastures. SimpliFly is safe for all horse breeds and easy to mix into regular feed for a seamless feeding routine.

How it works

• Feed-through action: works where flies breed, in manure, by interrupting the larval stage.
• Larvastop technology: diflubenzuron acts as a targeted larvicide without organophosphates.
• Palatable and convenient: alfalfa-based pellets mix into daily meals with minimal fuss.

Usage and anticipated results

For best results, begin in early spring before flies appear and continue through summer and fall to support ongoing barn fly control in various horse facilities. Combine with topical sprays and physical barriers for a holistic plan.

• Season-long coverage in barns, stalls, paddocks, and dry lots.
• 160-day supply in the 10 lb bucket provides ample feed-through coverage for many horses.
• Compatibility with existing fly-control routines helps protect turnout, riding, and training moments.

Note: This product is EPA-approved and designed for daily use as part of a broader fly-management strategy. Always follow label directions and consider local requirements.
