Understanding why horses attract flies is crucial for horse owners and anyone who interacts with these magnificent animals. Flies are more than just a nuisance; they can carry diseases, cause skin irritation, and disrupt a horse’s well-being.

The Allure of the Horse for Flies

Horses, with their warm bodies, wet noses, and often muddy environments, provide an irresistible feast for flies.

Factors Contributing to Fly Attraction

• Body Heat and Moisture: Flies are attracted to the warmth and moisture emanating from a horse’s body, particularly around the face, flanks, and tail.
• Sweat and Urine: Horses produce significant amounts of sweat and urine, which are rich in nutrients that flies find appealing.
• Manure: Horse manure is a breeding ground for many fly species, creating a concentrated source of attraction.
• Skin Conditions: Horses with skin irritations, wounds, or infections can be particularly attractive to flies, who are drawn to the blood and fluids.

Why Do Horses Attract Flies?

Horses, with their warm bodies, sweet breath, and sometimes less-than-pristine stables, are magnets for flies. These pesky insects can be a nuisance, causing discomfort, spreading diseases, and even biting. Understanding why horses attract flies can help owners take steps to minimize their presence and keep their equine companions happy and healthy.

The Allure of the Horse

Flies are drawn to horses for a variety of reasons, all related to the horse’s biology and environment.

Body Heat and Moisture

Horses are warm-blooded animals, generating a significant amount of body heat. Flies, being cold-blooded, seek out warm surfaces to regulate their body temperature. A horse’s body, especially in hot weather, provides an ideal source of warmth. Horses also produce sweat, which provides a source of moisture that flies need for survival.

Dung and Urine

Horses, like all mammals, produce manure and urine. These waste products are rich in organic matter, providing a feast for flies and their larvae. Flies lay their eggs in manure, and the larvae (maggots) feed on it, completing their life cycle.

Skin Secretions

Horses secrete oils and sweat through their skin, which can attract flies. These secretions contain salts and other nutrients that flies find appealing. (See Also: Can Horses Take Benadryl)

Standing Water

Horses often drink from water troughs or puddles, creating standing water that can be a breeding ground for flies. The larvae of many fly species develop in moist environments.

Types of Flies Attracted to Horses

Several types of flies are commonly found around horses, each with its own feeding habits and potential for causing problems:

• Stable Flies: These large, black flies are notorious for their painful bites. They feed on the blood of horses and other animals.
• House Flies: These ubiquitous flies are attracted to manure and decaying organic matter. They can spread diseases through their feces.
• Horn Flies: These small, gray flies are also blood feeders. They can cause significant irritation and reduce weight gain in horses.
• Horse Flies: These large, aggressive flies have a painful bite that can cause significant swelling and bleeding.
• Bot Flies: These flies lay their eggs on the horse’s coat, and the larvae burrow into the horse’s skin, causing irritation and potentially serious health problems.

Health Risks Associated with Flies

Flies pose a significant threat to the health of horses. They can transmit a variety of diseases, including:

• Equine Infectious Anemia (EIA): A viral disease that can be fatal to horses.
• West Nile Virus (WNV): A mosquito-borne virus that can cause neurological problems in horses.
• Strangles: A bacterial infection that affects the lymph nodes in the horse’s throat.
• Pink Eye (Conjunctivitis): A highly contagious eye infection.
• Summer sores: Skin lesions caused by a parasitic fly larva.

Controlling Flies Around Horses

Effective fly control is essential for maintaining the health and well-being of horses. Here are some strategies:

Sanitation

Regularly removing manure and urine from stalls and pastures is crucial. Dispose of waste properly to prevent fly breeding.

Fly Traps and Baits

Use fly traps and baits to reduce the number of adult flies. Place traps strategically around the barn and pasture.

Fly Predators

Encourage natural predators of flies, such as bats, birds, and spiders, by providing suitable habitat around the property.

Fly Repellents

Apply fly repellents to horses’ coats to deter biting flies. Choose repellents that are safe for horses and follow the manufacturer’s instructions.

Fly Sheets and Masks

Use fly sheets and masks to protect horses from biting flies, especially during peak fly season.

Stable Management

Ensure good ventilation in stables to reduce humidity and make the environment less hospitable to flies.

Recap

Horses attract flies due to their body heat, moisture, and waste products. Flies pose a significant health risk to horses, transmitting diseases and causing irritation. Effective fly control involves a multi-pronged approach, including sanitation, fly traps, repellents, and good stable management. By understanding why flies are attracted to horses and taking steps to control their populations, owners can help keep their equine companions healthy and comfortable.

Why Do Horses Attract Flies?

Why are flies so drawn to horses?

Horses attract flies for several reasons. Their warm bodies, sweat, and manure all provide a perfect breeding ground for flies. Flies are also attracted to the lactic acid in horse sweat, which smells appealing to them.

What kind of flies are most attracted to horses?

Some of the most common flies that bother horses include house flies, stable flies, horn flies, and horse flies. Each type has different feeding habits and preferences, but they all find horses to be a tempting target.

How can I tell if my horse has a fly infestation?

Signs of a fly infestation include excessive swatting, biting, restlessness, skin irritation, and even wounds caused by flies. You may also notice a large number of flies around your horse, especially in areas where they sweat or defecate.

What can I do to reduce the number of flies around my horse?

There are several things you can do to minimize fly populations around your horse. This includes keeping their living areas clean, removing manure regularly, using fly traps and repellents, and providing fans to create airflow.

Are there any natural ways to repel flies from horses?

Yes, there are several natural fly repellents that can be effective. These include essential oils like citronella, eucalyptus, and peppermint, as well as garlic and apple cider vinegar sprays.
