Buying Guide: Key Purchase Considerations
When choosing fly control for horses, consider the following:
- Protection type: Spot-on vs. spray vs. masks. A mix can address different scenarios and weather conditions.
- Duration and reapplication: Spot-ons often last up to two weeks; sprays vary by formulation and climate.
- Safety and sensitive areas: For eyes, ears, and wounds, choose roll-ons or ointments with skin-friendly ingredients.
- Coverage and ease of use: Masks provide full-face protection, while sprays and spot-ons target the body and mane areas more efficiently.
- Environmental considerations: Water-based formulas are less greasy and easier to rinse; consider barns, pastures, and water quality.
- Durability and fit: Masks should fit well without rubbing; consider sizes and adjustable closures for growing horses.
- Multi-species compatibility: Some products work for dogs and premises as well; assess whether shared use is beneficial.
- Application logistics: For frequent handlers or riders, quick-apply formats reduce downtime and stress for the horse.
