Did you know that horse flies can consume up to three ounces of blood per day from a host? These stout flies with metallic or iridescent eyes are not just annoying but also carriers of various animal diseases. Commonly found around streams, marshes, and wooded areas, horse flies can be a major nuisance for both humans and animals. In this article, we will explore the behaviors, habitats, identification, feeding habits, and management of horse flies to help you better understand and deal with these pesky insects.
Key Takeaways:
- Horse flies can consume up to three ounces of blood per day from a host.
- Horse flies are carriers of various animal diseases.
- They are commonly found around streams, marshes, and wooded areas.
- Horse flies can be a major nuisance for both humans and animals.
- Understanding their behaviors and habitats can help in managing their populations.
Horse Fly Behaviors and Habitats
Adult horse flies are fast and strong fliers, and they are usually found in areas near streams, marshes, and wooded areas. They are attracted to moist environments and are commonly seen around ponds, marshes, and other water bodies.
Horse flies are active during the day and prefer to feed on horses and other livestock, although they will also bite humans. They are known to be pests to both humans and animals, and can cause significant discomfort and pain with their bites.
Horse flies lay their eggs on vegetation near wet habitats, such as marshes or streams, and the larvae develop in the mud in these areas. It is important to reduce the amount of standing water on your property to help keep horse fly populations low.

Horse Fly Identification and Characteristics
Horse flies are easily identifiable by several key characteristics
- Large Size: Horse flies can grow up to 1.25 inches in length, making them one of the largest species of flies.
- Metallic or Iridescent Eyes: The eyes of horse flies are distinct and shiny, often displaying metallic or iridescent colors. The eyes of males meet dorsally, while the eyes of females are separate.
- Brown and Black Body: Horse flies have a sturdy body that is usually brown or black in color.
- Clear or Cloudy Wings: Their wings can be either clear or cloudy.
- Slicing Mouthparts: Horse flies have mouthparts resembling razors, which they use to slice into the skin and feed on blood.
Horse flies are active during the warm months and are most commonly found in areas with dense vegetation near bodies of water, such as streams, marshes, and wooded areas. They are strong fliers and can be aggressive in pursuing their prey. The females require a blood meal to produce eggs, while the males feed on nectar, honeydew, and plant sap.
Horse Fly Diet and Feeding Habits
Horse flies are bloodsucking insects that rely on a specific diet to survive and reproduce. Understanding what horse flies eat can help in managing their populations and reducing their impact on humans and animals.
What horse flies eat:
- Females: Horse fly females are the ones responsible for blood feeding. They require the protein found in blood to produce viable eggs. These bloodsucking females can be a serious nuisance and pose health risks to both humans and animals. When horse fly populations are abundant, they can consume three ounces or more of blood per day from a host. Horses and other livestock are the primary targets, but horse flies are also known to bite humans.
- Males: Unlike the females, horse fly males do not feed on blood. Instead, they nourish themselves by feeding on nectar, honeydew, and plant sap. Males play a crucial role in pollination, as they transfer pollen while foraging on flowers.
Horse flies have evolved specialized mouthparts, known as slicing mouthparts, which allow them to penetrate the skin and extract blood from their host. They are attracted to the carbon dioxide and other chemical cues emitted by their hosts, enabling them to locate their blood meals more efficiently.
It’s important to note that although horse flies require a blood meal, they also serve as pollinators when they feed on nectar. Therefore, efforts to control horse fly populations should be targeted at managing their presence and minimizing their impact on humans and animals, rather than eradicating them entirely.
Finding Horse Flies on Your Property
Horse flies are commonly found around streams, marshes, and wooded areas. They are attracted to moist environments and can be seen near ponds, pools, and other water bodies. If you have a property that is located near these habitats, you are more likely to encounter horse flies. They are especially active during the warmer months and can be a nuisance for humans and animals.
They are strong fliers and can easily move from one location to another, so it is important to take preventive measures to minimize their presence. Horse flies can also be found on horses or livestock, as they are attracted to the carbon dioxide and other chemicals emitted by these animals.
Preventing Horse Flies on Your Property
To reduce horse fly populations on your property, there are several steps you can take:
- Eliminate standing water: Horse flies lay their eggs in wet environments, so reducing standing water sources such as puddles, bird baths, or other containers can help minimize their breeding areas.
- Keep grass and vegetation trimmed: Horse flies are attracted to tall grass and dense vegetation, so keeping your lawn well-maintained can discourage their presence.
- Use repellents: Applying insect repellents that are specifically formulated to repel horse flies can provide some protection when spending time outdoors.
- Install screens: Adding screens to windows and doors can prevent horse flies from entering your home or other buildings on your property.
- Consider professional pest control: If horse flies are a persistent problem on your property, it may be beneficial to consult with a pest control professional who can assess the situation and recommend appropriate treatments.
Protecting Yourself and Your Animals
When spending time outdoors in areas where horse flies are present, it is important to take steps to protect yourself and your animals:
- Wear protective clothing: Covering exposed skin with long sleeves, long pants, and hats can help minimize the risk of horse fly bites.
- Use insect repellents: Applying insect repellents to your skin and your animals can provide additional protection against horse flies.
- Avoid peak activity times: Horse flies are most active during the warmer parts of the day, so minimizing outdoor activities during these times can reduce the chances of encountering them.
- Protect animals with fly masks: Using fly masks on horses and other livestock can provide some relief from horse fly bites.
By being proactive and taking preventive measures, you can minimize the presence of horse flies on your property and enjoy a more comfortable outdoor experience.
Conclusion
Horse flies are notorious for their painful bites, causing discomfort for both humans and animals. Effective horse fly management and control is essential to reduce their presence and minimize the risk of bites. To achieve this, it is crucial to implement various preventive measures.
Firstly, reducing standing water on your property can significantly decrease horse fly populations as they are attracted to moist environments. By eliminating stagnant water sources, you can create an unfavorable breeding ground for these pests.
Additionally, using repellents can deter horse fly infestations and protect yourself from their bites. Applying repellent products that specifically target horse flies can act as an effective barrier and reduce the likelihood of encounters.
