🐴 Vet-Approved Guide to the Best Horse Fly Supplements in 2025 🦟

Flies are more than just a nuisance for our equine companions—they can cause discomfort, transmit diseases, and lead to serious health issues. As we step into 2025, it's essential to stay updated on the most effective and safe fly control methods. This comprehensive guide by Dr Duncan Houston delves into the latest and most effective fly supplements for horses, ensuring your horse remains comfortable and healthy throughout the fly season.

🧪 Understanding Fly Supplements: IGRs vs. Natural Deterrents

Fly supplements for horses primarily fall into two categories:

1. Insect Growth Regulators (IGRs): These compounds disrupt the life cycle of flies by preventing larvae from developing into adults. Common IGRs include diflubenzuron and cyromazine. They pass through the horse's system and act in the manure, inhibiting fly development without affecting the horse.
2. Natural Deterrents: Ingredients like garlic, apple cider vinegar, and diatomaceous earth make the horse less appealing to flies. These substances can mask the horse's scent or create an environment that's inhospitable to flies.

🧠 Factors to Consider When Choosing a Fly Supplement

When selecting a fly supplement for your horse, consider the following:

• Horse's Environment: Horses in warmer climates or those spending significant time outdoors may benefit more from fly supplements.
• Existing Health Conditions: Horses with skin allergies or sensitivities may require specific ingredients to avoid adverse reactions.
• Palatability: Ensure the supplement is palatable to your horse to guarantee consistent intake.
• Combination with Other Fly Control Methods: Supplements are most effective when used in conjunction with other fly control measures like fly masks, sprays, and proper manure management.

📅 When to Start Supplementing

It's advisable to begin administering fly supplements early in the spring, before flies become active. This proactive approach helps in reducing the initial fly population and provides better control throughout the season.

⚠️ Safety and Precautions

• Consult Your Veterinarian: Always discuss with your vet before introducing any new supplement to ensure it's appropriate for your horse's specific needs.
• Follow Dosage Instructions: Never exceed the recommended dosage as it can lead to health complications.
• Monitor for Adverse Reactions: Keep an eye out for any signs of allergies or sensitivities when starting a new supplement.
