Fly control on dairy farms requires understanding fly biology and integrating multiple control methods. Different species have different breeding sites, behaviors, and control vulnerabilities. Effective programs attack flies at multiple life stages and locations.
House flies breed in decaying organic matter—spilled feed, manure accumulations, bedding piles. Control focuses on sanitation (eliminating breeding sites), biological control (parasitic wasps, larvicides), and adult knockdown when populations spike. Baits and traps provide supplemental control.
Stable flies breed in moist organic matter including old hay, silage seepage, and feedlot edges. Their painful bites cause bunching behavior and production losses. Control requires breeding site elimination plus targeted spray applications to resting surfaces.
Horn flies spend their entire lives on cattle, leaving only to lay eggs in fresh manure. Pour-on insecticides, dust bags, oilers, ear tags, and boluses provide control. Resistance management is critical—rotate chemical classes and use non-chemical methods to delay resistance.
Face flies cluster around eyes and muzzle, transmitting pinkeye and irritating cattle. Similar control methods to horn flies, with emphasis on face protection through dust bags placed where cattle must use them.
Integrated pest management (IPM) combines cultural, biological, and chemical controls. No single method provides complete control—effective programs use multiple tactics targeting different life stages and fly species.

Buying Considerations
Important factors to consider when evaluating What Are Fly Control Products for Dairy Farms?:
- Resistance Management Strategy: Evaluate products with different modes of action to prevent resistance development. Rotate between organophosphates, pyrethroids, and IGRs seasonally to maintain effectiveness over time.
- Application Method Compatibility: Consider existing infrastructure and labor availability. Automated systems require initial investment but reduce long-term labor costs, while manual applications offer more flexibility but higher ongoing costs.
- Residue and Withdrawal Requirements: Review milk and meat withdrawal periods for all products used. Some products have zero withdrawal times while others require 24-48 hours, affecting operational flexibility during treatment periods.
- Environmental Impact and Sustainability: Assess impact on beneficial insects and water sources. Choose products with lower environmental persistence and consider organic-approved options if targeting premium markets.
- Cost Per Day of Protection: Calculate total cost including product, application, and labor over effective treatment period. Compare per-cow daily costs which typically range from $0.15-0.45 depending on method chosen.
Evaluation Questions
Key questions to consider when evaluating What Are Fly Control Products for Dairy Farms?:
- Which fly species are causing the most problems?
- What breeding sites exist that we can eliminate?
- Are we rotating insecticide classes to prevent resistance?
- What biological and physical controls could reduce chemical reliance?
- How are we monitoring to evaluate program effectiveness?
Common Mistakes to Avoid
Avoid these common mistakes when implementing What Are Fly Control Products for Dairy Farms?:
- Using single product approach without rotation
- Treating only adult flies without addressing breeding sites
- Inconsistent application timing and coverage
- Ignoring weather conditions during application
