Formula 707 MultiFly Feed-Thru Fly Control Pellets for Horses

In this review of Formula 707 MultiFly Feed-Thru Fly Control Pellets, the bottom line is simple: this is a practical, affordable feed-through option for horse owners who need a reliable way to reduce barn fly populations while avoiding organophosphate chemistry. The reviewer found the product's novaluron-based approach to be effective at interrupting the fly life cycle and appreciated that one small, alfalfa and wheat midd-based pellet serving is easy to add to daily feed. This review focuses on effectiveness, safety, palatability, cost, and everyday barn use.

Key Features

• Active ingredient: Novaluron is an insect growth regulator that targets immature flies and helps disrupt the life cycle for sustained population reduction.
• Safety profile: The formula does not use organophosphates, offering a safer chemistry for horses and handlers compared with older fly-control compounds.
• Palatable pellet: The alfalfa and wheat midd base makes the pellets easy to mix into a horse's daily ration and horses readily accept the serving.
• Cost effectiveness: At a lower daily cost than comparable products, MultiFly aims to deliver the same control without increasing routine expense.
• Manufactured in the USA: Produced in Colorado in a facility with a long history, which appeals to buyers who prioritize domestic manufacturing.

Who It's For

Formula 707 MultiFly is well suited for barn owners, small farms, and equestrians who want to reduce fly pressure without switching to topical repellents or changing manure management practices immediately. It is particularly useful where consistent, daily administration is feasible and where palatability is important for horses that are sensitive to feed changes.

Those who need instant knockdown of adult flies or who prefer spray-only strategies should look elsewhere; feed-through IGRs work by interrupting immature stages and produce noticeable population drops over weeks rather than hours.

Pros & Cons

Pros

• Effective at breaking the fly life cycle with novaluron, producing substantial reductions in fly numbers when used daily.
• Not an organophosphate, so it offers a safer chemistry profile for routine use around horses.
• High palatability from alfalfa and wheat midd makes daily dosing simple and stress-free for most horses.
• Lower daily cost compared with similar feed-through products, improving ongoing use affordability.

Cons

• Population reductions are gradual as the product targets immature stages, so it is not an immediate adult fly knockdown.
• Requires consistent daily administration to maintain control, which may be a drawback for irregular feeding routines.

Our Verdict

Formula 707 MultiFly is a sensible feed-through choice for owners who want a safer, palatable way to cut fly populations over time.

Frequently Asked Questions

How fast will I see fewer flies?
Expect to see population reductions over several weeks because the product interrupts immature stages rather than instantly knocking down adults.

Is it safe to use every day?
Yes, the active ingredient is an insect growth regulator and not an organophosphate, and the pellets are formulated for daily administration with feed.

Will my horse eat it?
Most horses accept the alfalfa and wheat midd-based pellets readily, making dosing straightforward in regular feed.
