NaturesGoodGuys Fly Exterminators 20000

The 20000 model offers a substantial release package designed to disrupt fly reproduction in equine environments. Its eggs hatch over 7-14 days at 70 DF or higher, providing a predictable timeline for population reduction. Release pouches are included, simplifying deployment. The product is described as harmless to humans, pets, birds, and beneficial insects, which aligns with integrated pest management goals for barns and paddocks.
Key considerations
Suitable for medium to large barns. Ensure proper placement to maximize hatch timing and coverage. Consider combining with routine cleaning to prevent fly breeding sites.
NaturesGoodGuys Fly Exterminators 10,000

This 10,000-unit option is positioned for ongoing control with monthly releases during warmer months. It emphasizes safety for humans, pets, birds, and beneficial insects, supporting a balanced barn ecosystem. The product page states a guarantee of live delivery, underscoring reliability in shipment and establishment of the beneficial predators.
Usage notes
Plan monthly replenishment during peak fly season. Monitor fly activity and adjust release frequency if needed to maintain effective suppression.
NaturesGoodGuys Fly Exterminators 50000

The 50000-size product is designed for high-volume fly pressure, offering a large-scale option for busy stables or multi-paddock operations. Like other NaturesGoodGuys products, it emphasizes gentle protection for people and pets while targeting pest flies. The eggs hatch in a predictable window, supporting planning and coordination with other fly management practices.
Practical considerations
Best for larger facilities or seasonal peaks. Combine with sanitation practices to address larvae and eggs, not just adults, for best results.
NaturesGoodGuys Fly Exterminators 2000

The compact 2000-size option provides flexibility for smaller barns or targeted treatment zones. Despite its smaller footprint, the product maintains the same safety profile and hatch-based lifecycle management. Release pouches are included to simplify deployment, making it easy to start a bio-control program with limited space.
Best fits
Ideal for smaller stables, paddocks near entryways, or as a trial starter before scaling up to larger formats.
NaturesGoodGuys Fly Exterminators 10000 (Repeat)

This second 10,000-unit variant reinforces the concept of ongoing, scheduled control throughout fly seasons. It emphasizes safety and a continuous supply of predatory insects to keep populations in check with minimum disruption to barn activities. Repeated releases help maintain a steady suppression trajectory in facilities with persistent fly pressures.
Buying Guide: Key Purchase Considerations For Fly Predators In Horse Environments
- Biological safety and compatibility: Choose products explicitly described as harmless to humans, pets, birds, and beneficial insects to minimize risk in stables and pastures.
- Lifecycle management: Look for releases timed with fly life cycles (eggs to hatch windows) to disrupt reproduction, not just feed on adults.
- Facility size and layout: Large barns or multiple paddocks may require higher-volume products (e.g., 50,000 units) or staged releases to cover all areas effectively.
- Delivery method: Release pouches simplify deployment; ensure the product includes clear instructions for placement to maximize exposure to breeding sites.
- Seasonality: Some products are recommended for warm months with monthly releases. Plan to align purchases with local climate and fly activity patterns.
- Sanitation synergy: Combine biological control with barn hygiene, manure management, and water trough cleanliness to reduce breeding sites and extend product efficacy.
- Monitoring: Track fly activity and predatory establishment over time. Adjust release frequency or product size based on observed results and pest pressure.
- Regulatory and environmental considerations: Verify compatibility with existing pest management plans and any local regulations regarding release programs.
- Cost and logistics: Weigh upfront cost against anticipated long-term reductions in fly-related losses and workload. Evaluate delivery reliability and ease of restocking.
- Alternatives and complements: Consider non-predator options like repellents and inhibitors as a multi-pronged approach, especially during peak seasons.
In sum, choosing a fly predator program involves balancing barn size, seasonality, and maintenance commitments. The products highlighted here provide safe, scalable options that align with integrated pest management goals for horses and equine facilities. Always follow product-specific instructions and integrate biological controls with good barn sanitation for best results.
