Practical environmental management steps can make a big dent in insect populations around horse farms, often without needing pesticides. 🪰🦟
🦟 REDUCE MOSQUITO BREEDING
• Dump standing water routinely.
- Mosquitoes need water to complete their life cycle. Empty water that collects in flowerpots, buckets, barrels, etc.
- Drill drainage holes in tire swings and keep children’s wading pools empty and stored on their side when not in use.
• Refresh water troughs frequently. Change water troughs at least twice weekly to discourage mosquito breeding.
• Mosquito-proof barns and stables:
- Install and maintain secure screens on windows and doors.
- Use fans (mosquitoes/flies avoid strong air movement because they can’t control flight well).
- Consider lighting choices. In barns, swapping incandescent bulbs for fluorescent-type fixtures can make the area less attractive to mosquitoes.
🪰 SANITATION & FACILITY MANAGEMENT
• Manure and waste handling (sanitation) is foundational. Remove stall and paddock litter and dispose of it properly.
• Stacking manure to reduce surface area is recommended; for small facilities, covering stacks with plastic film can help reduce fly breeding.
• If hay is fed in paddocks, avoid allowing hay to get trampled into the footing/substrate near feeders—flies can develop in that material, sometimes even beneath the soil surface.
⚠️ REMEMBER: not all flies come from your manure pile. “Feed-through” fly products are only potentially helpful if the flies are actually breeding in manure from horses on-site; in contrast, face flies, horn flies, and tabanids do not breed in horse manure, while house flies and stable flies can.
TRAPS & NON-CHEMICAL TOOLS
• Use traps to monitor and help manage flies. Traps can be useful to track fly numbers, but placement matters.
- Put traps where flies are numerous, and for stable flies, as close to the animals as possible.
• Use fans inside barns as pesticide-free protection. This is one of the simplest, most effective barn strategies for flies that enter.
• UV light traps can help indoors. If used, they’re recommended inside barns; avoid placing them outside or running them after dark.
