Horseflies are unwelcome guests in any situation. Unlike other flies, which are pesky but often harmless, horseflies can inflict painful bites. If you’ve ever felt a sharp pinch and seen a fly buzzing away, you likely encountered this type of insect. Learn more about what horseflies are and what you can do to escape them.

What Are Horseflies?

Horseflies are blood-sucking insects that will give you a painful bite. Though they may look similar to ordinary houseflies at first glance, there’s a big distinction between these two pests. Once you’ve suffered the bite of a horsefly, you’ll probably be ready to tackle the task of extermination. This unwanted pest is a major nuisance in or around the home.

What Do Horseflies Look Like?

Horseflies are large flies that can measure over an inch in length. They’re black to dark brown with bright eyes that are typically black, purple, or green. Their wings can be transparent or solid-colored. They have stout bodies, six legs, two wings, and antennae. Their overall appearance is similar to the housefly only much larger, and in some cases, they are more colorful. Due to their size, they’re sometimes mistaken for bees before given a closer examination.

Though you probably won’t have the chance to examine their mouths closely, female horseflies have six sharp mouthparts that are made for cutting and tearing; this is what they use to deliver their notoriously painful bites. However, not all horseflies will bite people. Male horseflies lack these vicious mouthparts and only collect pollen.

Female horseflies need blood from their prey to get the necessary nutrients to reproduce. Unlike mosquitoes, which delicately pierce the skin and suck blood, horseflies pierce the flesh and tear open a wound. They will bite their host multiple times if needed until they have had their fill of blood.

Where Do Horseflies Live?

Horseflies can be found in many parts of the United States, though they present the biggest problem in Florida. They enjoy the warmth and humidity that’s available year-round in this state. These insects prefer warm climates where they can find a habitat near a body of water. Horseflies are typically forest or marsh dwellers, though they will move to any area where there’s abundant prey. Beach towns are famous for horseflies because they can stay near the water and often find plenty to feed on.

An adult horsefly can fly for over 30 miles, covering a significant amount of territory in search of food. However, this is not their typical approach to hunting. Horseflies are more likely to perch on the ground, sitting in roadways or on wooded paths waiting for an animal to pass by. They prefer to feed around the middle of the day are most active when the air is still and hot.

Horseflies are attracted to light, so you may find them gathering near windows if they get into the house. They find their prey by looking for movement and dark color. They can also detect the carbon dioxide that’s breathed out by living creatures and will use this trait to find animals to feed on.

Problems With Horseflies

Horseflies can carry and transfer diseases through their bites. However, in the United States, most horsefly diseases are only spread to livestock and not to humans; this isn’t much reassurance for the livestock owners, however, who want to protect their animals from these pests.

Though it’s unlikely that you’ll catch a disease from a horsefly bite, you may suffer from an allergic reaction. These bites can also lead to bacterial infections if they’re not cleaned and properly treated. These flies will respond to certain insect repellents, such as those with DEET. However, this is only a temporary solution. To find out how to get rid of horseflies in or around your home, contact an exterminator.
