Can I keep flies off my horse naturally? Yes, you can keep flies off your horse using a mix of good stable management, physical barriers, and natural or chemical repellents. Flies bother horses a lot. They cause stress and can spread diseases. Getting rid of them keeps your horse happy and healthy. This guide offers many ways to fight the fly problem.
The Problem with Flies on Horses
Flies are more than just annoying. They bite, cause pain, and can make your horse sick. Different flies cause different problems.
Types of Pesky Flies
- House Flies: These like manure and moist areas. They often gather around the eyes and wounds, spreading germs.
- Stable Flies: These bite painfully, usually on the legs. They prefer standing near manure or wet hay.
- Horse Flies and Deer Flies (Biting Flies): These deliver a painful, deep bite. They are strong flyers and often target the horse’s flanks and belly.
- Face Flies: These are very annoying around the eyes, ears, and muzzle. They spread diseases like pink eye.
Flies cause horses to stomp, swish their tails constantly, and nervously flick their skin. This constant movement wastes energy. Severe infestations can lead to skin infections and allergic reactions, like sweet itch.
Solid Fly Control Strategies for Horses
Good fly control needs many steps working together. It is not just about spraying; it is about changing the environment. Fly control strategies for horses must include habitat removal, physical barriers, and chemical treatments.
Sanitation: Removing the Breeding Grounds
Flies need damp, dirty spots to lay eggs. Cleaning up is the first, and most important, step.
Manure Management
Flies breed fast in horse droppings. Remove manure often. Daily removal is best, especially in warm weather.
- Pick pastures frequently: Do not let manure pile up in the field.
- Keep stalls clean: Scoop stalls every day. Replace soiled bedding quickly.
- Compost properly: If you compost manure, ensure the pile gets hot enough to kill fly larvae. A well-managed compost heap cooks the eggs and larvae.
Managing Wet Areas
Flies love standing water and damp spots.
- Fix any leaky water troughs.
- Ensure pastures drain well after rain. Avoid muddy areas where flies breed.
- Keep spilled feed cleaned up right away. Wet, spoiled feed attracts flies just like manure.
Physical Barriers: Blocking the Bugs
Physical tools stop flies from landing on your horse. These tools are great for keeping flies off pasture horses where sprays might not last all day.
Fly Sheets for Horses
Fly sheets for horses are light sheets that cover the horse’s body. They are often made of mesh material.
- Benefits: They offer protection from biting flies even when you are not around. They also help block harmful UV rays.
- Features to look for: Look for sheets with neck covers and belly guards for full coverage. Make sure the material is breathable so the horse does not overheat.
Fly Masks for Horses
The head and eyes are prime targets for face flies. Fly masks for horses provide excellent protection.
- Eye Protection: Masks with UV blocking materials also help shield sensitive eyes from the sun.
- Ear Covers: Some masks have built-in ear covers to keep flies out of the ears, which can be very irritating.
- Fly Fringe: For horses sensitive around the eyes but who won’t wear a full mask, a fly fringe that hangs over the eyes offers some relief.
Chemical and Repellent Applications
When managing an infestation, using repellents is necessary. You have options ranging from strong chemicals to gentler, organic fly repellents for horses.
Best Fly Sprays for Horses
When choosing a spray, check the active ingredients. Pyrethrins and Permethrin are common and effective, but they are synthetic chemicals.
- When to Apply: Apply sprays directly to the horse before riding or turnout. Reapply as directed by the label, especially after heavy sweating or rain.
- Spot Treatment: Focus the spray on high-traffic areas like legs, chest, and neck where flies love to land.
Natural Fly Repellents for Horses
Many horse owners prefer gentler options. Natural fly repellents for horses often use essential oils.
- Common Natural Ingredients: Cedarwood oil, peppermint oil, citronella, and lemongrass are popular scents that flies dislike.
- Effectiveness Note: Natural sprays often need reapplication more frequently than chemical ones because the oils evaporate faster.
Homemade Fly Spray for Horses
For those who like to mix their own solutions, a homemade fly spray for horses can be a good alternative. Always test a small patch of skin first to check for sensitivity.
A simple recipe might mix water, white vinegar, and a few drops of a preferred essential oil (like citronella). Vinegar helps preserve the mix and can also deter flies.
| Ingredient | Purpose | Notes |
|---|---|---|
| Water | Base liquid | Use distilled water if possible. |
| White Vinegar | Mild repellent, preservative | Flies dislike the smell and taste. |
| Essential Oils (e.g., Citronella, Cedarwood) | Strong scent barrier | Use sparingly; too much can irritate skin. |
| Liquid Soap (mild) | Helps oils mix with water | Use a tiny bit to emulsify the mixture. |
Advanced Tactics for Fly Management
For persistent problems, especially with pests like horse flies, you need to look beyond just treating the horse. This involves managing horse flies naturally and treating the environment.
Fly Traps and Baits
Traps catch flying adults before they can bother your horse.
- Glue Traps: These are sticky boards placed near entrances or high-traffic areas. They catch many flies but can be unsightly.
- Water/Bait Traps: These use a lure (like yeast or protein) to attract flies into a container from which they cannot escape. These are effective for reducing the population near barns.
Fly Parasites
This is a biological approach to fly control for horses naturally. Fly parasites are tiny, beneficial wasps. They attack fly pupae in the manure.
- How it Works: You purchase containers of these beneficial insects. You release them into your manure piles regularly throughout the fly season.
- Benefit: They attack flies at the larval stage, stopping the next generation before it hatches. Consistent release is key for success.
Managing Paddock Areas
The goal here is to make the environment less inviting to flies.
- Minimize Mud: If you have a muddy paddock, try to cover high-traffic areas with gravel or sand to improve drainage. Mud is a major breeding ground for many fly types.
- Tree Lines and Shade: While flies thrive in sun, dense, dark, sheltered areas can also harbor them. Keep vegetation trimmed back around barns to improve air flow. Good air movement helps deter many species.
Tackling Specific Fly Issues
Different flies require different attack plans.
Keeping Flies Out of the Barn
A clean barn is the best defense.
- Door Strategy: Keep barn doors closed during peak fly hours (mid-morning to late afternoon). Use screens on windows and doorways if possible.
- Stable Fly Control: Since stable flies breed in soiled bedding, changing bedding frequently is crucial. Consider using wood shavings that dry out faster than straw.
Protecting Sensitive Areas (Eyes and Wounds)
Flies congregating on wounds or around eyes can cause serious infections.
- Wound Care: Keep any cuts or scratches covered with a protective dressing. Use fly sprays specifically labeled as safe for use around wounds, or rely on physical bandages.
- Eye Care: If your horse suffers from chronic pink eye due to face flies, use a fly mask for horses religiously. Some masks even have treatments embedded in the material.
The Role of Diet and Supplements
What your horse eats can also play a small role in fly defense. Certain supplements are marketed to change the horse’s scent or blood chemistry, making them less attractive to insects.
- Garlic: Some studies suggest feeding garlic supplements can repel flies due to the sulfur compounds released through sweat. However, results are mixed, and you must use caution not to overfeed garlic.
- Brewer’s Yeast: Often included in fly supplements, brewer’s yeast is believed to work similarly to garlic by altering the horse’s scent profile slightly.
Always talk to your veterinarian before starting any new supplement regimen, especially when managing horse flies naturally alongside conventional methods.
Integrating Fly Control into Daily Routine
Consistency is the secret weapon against flies. If you only spray once a week, you will lose the battle.
A Sample Daily Fly Control Checklist
| Time | Task | Tools Used | Notes |
|---|---|---|---|
| Morning | Scoop stalls and high traffic areas. | Shovel, Wheelbarrow | Removes fresh breeding material. |
| Before Turnout | Apply fly spray or use natural fly repellents for horses. | Spray bottle, Wipes | Reapply if sweating heavily. |
| During Day | Check fly sheets for horses for tears or slipping. | None | Ensure full coverage remains intact. |
| Evening | Pick fly traps if necessary. Feed only what will be eaten. | Gloves, Trap cleaner | Prevents attracting night feeders. |
| Weekly | Deep clean water troughs. Compost manure pile thoroughly. | Hose, Rake | Breaks the fly life cycle drastically. |
Comprehending Fly Behavior for Better Control
Knowing why flies do what they do helps you place your defenses effectively. Flies are attracted to dark colors, moisture, and odor (especially ammonia from urine).
If you notice flies heavily concentrated on one part of the horse (like the fetlocks), you likely have stable flies or biting midges present. Focus your barrier methods (like leg wraps or targeted sprays) there. If they are all around the eyes, prioritize the fly mask.
The weather plays a big part too. Flies are most active when it is warm, humid, and still. On cool, windy days, fly activity drops sharply, offering a natural break in the pressure. Use these calmer days to conduct heavy cleaning tasks.
Frequently Asked Questions (FAQ)
How long do commercial fly sprays last on a horse?
Most standard, effective fly sprays last between two to four hours, especially under direct sun or if the horse is active. Heavy-duty or “long-lasting” formulas might claim up to eight hours, but reapplication is often needed sooner if the horse sweats or gets wet.
Are essential oils safe to use as homemade fly spray for horses?
Many essential oils are safe when highly diluted. Oils like peppermint, rosemary, and cedarwood are common in homemade fly spray for horses. However, they must be mixed properly with a carrier (like water and a tiny bit of mild soap). Never apply concentrated essential oils directly to a horse’s skin, as this can cause burns or severe irritation.
Do fly masks really stop flies from causing eye infections?
Yes, fly masks for horses are highly effective at stopping flies from landing directly on the sensitive eye area. This is the best way to prevent the mechanical transmission of bacteria that causes pink eye. Ensure the mask fits well so flies cannot crawl underneath it.
What is the best way to manage flies in a large pasture without daily spraying?
For large areas, rely on environmental control and physical barriers. Use fly sheets for horses for continuous protection. Implement aggressive manure removal (using a tractor or ATV spreader to scatter droppings thinly over a wide area works better than piling them). Deploy large-scale water/bait traps around the perimeter of the pasture. Biological control using fly parasites is also excellent for large areas.
Can I stop using fly control in the winter?
Yes, in regions that experience hard freezes, fly activity nearly stops in the winter because the larvae cannot survive the cold ground temperatures. However, in warmer, milder climates, you must maintain some level of management year-round.
