JustiFLY Single: Feedthrough Cattle Fly Control
JustiFLY Feedthrough is a convenient 360-gram add-pack designed for on-farm use. It treats one 50-lb bag of free-choice mineral, targeting horn fly, stable fly, house fly, and face fly. The product works through the cattle’s digestive system to interrupt the life cycle, reducing fly populations over time. It is positioned as an economical option, with long-term head-level impact per day. Consider integrating with mineral programs to maintain consistent intake and effectiveness against multiple species.
JustiFLY Feedthrough Cattle Fly Control (3-Pack)
This 3-pack option provides multiple 360-gram add-packs for broader coverage across a herd. By consistently treating free-choice minerals, it disrupts the fly lifecycle for several species common on cattle operations. The packaging is designed for bulk-farm use and aims to lower per-head costs while maintaining efficacy against horn, stable, house, and face flies.
Co-RAL 1% Livestock Dust
Co-RAL 1% Livestock Dust is designed for use directly on cattle, offering multi-species control including horn flies, face flies, and lice. It’s a ready-to-use dust that can be applied to animals without lengthy withholding or waiting periods between treatment and milk or meat use. This option is practical for on-animal applications and can be part of an integrated control strategy, particularly when dealing with heavier infestations or mixed herd species.
Purina Fly Control Supplement for Cows
Purina Fly Control Supplement for Cows combines wind and rain mineral supplementation with targeted fly control benefits. The product provides essential macro and trace minerals, plus vitamins A, D, and E to support health, reproduction, and growth. It’s designed for consistent consumption, helping cattle receive daily mineral and fly-control benefits across seasons, while minimizing dietary deficiencies that could affect immunity and overall herd performance.
JustiFLY Feedthrough Cattle Fly Control (6-Pack)
This 6-pack provides a bulk supply of the JustiFLY feedthrough product, allowing for extended coverage across larger herds or frequent mineral replacement cycles. Like the single and multi-pack variants, it works by disrupting the life cycle of four major flies that affect cattle, helping reduce fly-related stress and potential disease transmission over time.
JustiFLY Feedthrough Cattle Fly Control (12-Pack)
The 12-pack option is intended for large herds or operations seeking long-term management with minimal restocking. It maintains the same mechanism as the other JustiFLY feedthrough products, treating minerals to interrupt the fly life cycle. This pack aims to simplify procurement and ensure consistent fly control across multiple seasons.
Buying Guide
Key considerations when selecting fly control products for cattle include the mode of action, target species, delivery method, and compatibility with existing mineral programs. Feedthrough larvicides work by interrupting the fly life cycle through treated minerals, providing systemic control over several fly species. Dust products offer on-animal contact control, useful in high-density herds or rapid infestations. Mineral-based fly control supplements combine nutrition with pest management, supporting cattle health while reducing fly pressure.
- Mode of action and spectrum: Choose products that address the most common flies in your region (horn, face, stable, house flies) and consider rotating products to delay resistance.
- Delivery method: Feedthroughs require mixing with minerals; dusts require direct on-animal application. Align with labor capacity and handling practices on the farm.
- Herd size and stocking density: Bulk packs may offer better value for larger operations; smaller herds might benefit from single or 3-pack options.
- Withdrawal and milk/beef safety: Check any withdrawal times or restrictions; ensure compatibility with milk and meat production schedules if applicable.
- Seasonality and management plan: Fly pressure often varies by season. Pair chemical controls with sanitation, manure management, and pasture rotation for comprehensive control.
- Nutrition synergy: Mineral-based fly control can support overall herd health, but ensure minerals meet daily requirements to avoid deficiencies.
- Regulatory and label compliance: Always follow label directions, local regulations, and safety precautions when applying any pest control product.
All options above are designed to integrate with standard cattle care routines. For best results, tailor your program to the local fly species, climate, and grazing practices, and periodically reassess effectiveness with seasonal inspections and, if needed, professional advice.
