MultiFly Feed-Thru Fly Control Pellets for Horses - Breaks Fly Life

In this review of MultiFly Feed-Thru Fly Control Pellets for Horses, the bottom line is simple: this product is for horse owners who want a low-effort, barn-wide reduction in fly populations without applying topical chemicals. The reviewer found the Novaluron-based formula effective at interrupting the fly life cycle and easy to administer as a daily feed pellet, making it a practical choice for stables that prefer a palatable, ingestion-based approach rather than sprays or topical applications.

Key Features

• Novaluron insect growth regulator: Targets fly larvae development to reduce overall fly numbers rather than simply repelling adults.
• Non-organophosphate active ingredient: Offers a safer chemical profile compared with organophosphate treatments, which is reassuring around horses and handlers.
• Palatable pellet form: Alfalfa and wheat midd-based pellets are easy to mix into daily feed and are readily accepted by most horses, simplifying dosing.
• Cost-effective daily dosing: The 10 lb bag provides many servings, which lowers the daily cost compared with some alternatives while delivering comparable performance.
• Made in the USA: Manufactured in a Colorado facility with a long history, which can matter to buyers who prefer domestic production.

Who It's For

This product is best for barn owners and managers who want a practical, maintenance-level solution to reduce fly populations across a herd with minimal labor. It suits equine facilities that prefer treating the environment via the animals eating a feed-thru pellet instead of relying only on topical sprays, traps, or foggers.

Owners who need immediate knockdown of adult flies or who require a repellent action on the skin may want to combine this product with other control measures, because feed-thru insect growth regulators focus primarily on breaking the life cycle rather than instant adult fly elimination.

Pros & Cons

Pros

• Reportedly reduces fly populations significantly by interrupting larval development, so barns become more comfortable.
• Palatable pellets are easy to administer once daily with regular feed, reducing handling stress for horses.
• Not an organophosphate, which many users consider a safer option for repeated use around animals and people.
• Lower daily cost compared with similar treatments, making it attractive for larger herds or long seasons.

Cons

• Does not immediately repel or remove adult flies, so additional adult-targeting methods may still be needed for fast relief.
• Effectiveness depends on consistent daily administration and overall barn sanitation practices to achieve best results.
