Horn flies are one of the most economically damaging pests for pasture cattle, costing U.S. cattle producers nearly $2.3 billion annually. If left untreated, a small population of horn flies can rapidly multiply, leading to thousands of flies per animal. This not only causes excessive stress but also reduces weight gain, milk yield, and overall herd productivity. Fortunately, Altosid® IGR provides a scientifically backed, highly effective, and economical solution to break the horn fly life cycle and protect your cattle.
How Altosid® IGR Works
Altosid® IGR (Insect Growth Regulator) is an advanced feed-through solution designed to prevent horn fly pupae from developing into biting adults. When cattle consume feed supplemented with Altosid® IGR, the active ingredient passes through the animal and into the manure---the primary breeding ground for horn flies. This disrupts the fly life cycle before it even begins, ensuring long-term protection and reducing the need for labor-intensive fly control methods.
Proven Effectiveness and Economic Benefits
The impact of horn flies on cattle performance is significant, but Altosid® IGR has been proven to yield outstanding results:
- 15.8% Increase in Average Daily Gain: Research confirms that stocker cattle treated with Altosid® IGR gain significantly more weight compared to untreated cattle, improving overall profitability.
- 6:1 to 10:1 Return on Investment: A cost-effective solution that provides substantial economic returns.
- Milk Yield and Quality Improvement: University studies indicate that controlling horn flies leads to better milk production, benefiting both dairy and beef operations.
A Convenient, Stress-Free Solution
One of the standout advantages of Altosid® IGR is its ease of use. Unlike traditional fly control methods that require physical handling of cattle, Altosid® IGR is integrated into feed, allowing cattle to naturally distribute the product as they graze. It is available in various forms, including:
- Loose mineral
- Blocks
- Tubs
- Custom liquid feeds
By strategically placing feeders near watering holes and loafing areas, producers can ensure optimal consumption and effectiveness.
Resistant-Free Fly Control
Resistance is a major concern with many conventional fly control products containing organophosphates and pyrethroids. However, Altosid® IGR has been on the market for over 30 years with no known resistance cases, making it a sustainable long-term solution. Additionally, it is non-toxic to beneficial insects such as dung beetles and does not harm birds, fish, or mammals when used as directed.
Horn fly infestations pose a serious threat to cattle health and profitability, but Altosid® IGR provides a proven, cost-effective, and convenient solution. By interrupting the horn fly life cycle before it begins, producers can ensure a healthier, more productive herd with minimal labor and stress. Choose Altosid® IGR for smarter, science-backed fly control that delivers real results.
