BEST FLY SPRAYS FOR HOT, HUMID CLIMATES
When the heat, humidity, sweat, and bugs are at their worst, not all fly sprays perform equally. Here are four of the top choices used by horse owners in Florida and other humid climates:
🥇 PYRANHA WIPE N’ SPRAY
An oil-based formula known for excellent staying power. Great for turnout horses and those exposed to heavy fly pressure. Repels flies, gnats, mosquitoes, and ticks while holding up well to sweat.
🥈 PYRANHA AEROSOL
A favorite in many show barns. Easy to apply, leaves a nice shine on the coat, and provides excellent fly protection with the convenience of an aerosol can.
🥉 FARNAM ENDURE
One of the most effective non-oil-based sprays available. Designed to resist sweat and moisture, making it a popular choice for horses in work and turnout.
🏅 ABSORBINE ULTRASHIELD GOLD
A broad-spectrum fly spray that targets flies, mosquitoes, gnats, and ticks. Long-lasting protection and trusted by horse owners for years.
WHY DO OIL-BASED SPRAYS OFTEN WORK BETTER IN HOT WEATHER?
💧 Water-based sprays can break down more quickly when a horse sweats.
☀️ Oil-based formulas tend to adhere to the hair coat longer, helping them remain effective through heat, humidity, light rain, and turnout.
🐴 They often provide better residual protection, meaning you may not need to reapply as frequently during peak fly season.
That said, Farnam Endure is an exception and remains a top performer despite being water-based because of its sweat-resistant technology.
