1. Deer Flies
Deer flies, slightly smaller than house flies, emerge in the spring and use their scissor-like mouthparts to slice open skin, making deer fly bites notably painful. Deer flies are persistent biters and are known to be active during daylight hours. These pests are particularly troublesome in wooded areas and near bodies of water, where they seek out hosts for blood meals.
2. Horse Flies
Horse flies, similar to deer flies, slice into the skin when they bite, leading to pain and swelling. The large size of a horse fly can be intimidating, and their bites are often considered one of the most painful due to their intensity. Female horse flies require blood meals for reproduction, making them aggressive biters of humans and animals alike.
2.1. Do Horse Flies Bite Dogs?
Yes, horse flies do bite dogs. While most fly bites are relatively harmless, high populations can result in multiple bites, severely irritating a dog’s skin. The mouthparts of horse flies are equipped with scissor-like mandibles that slice into the skin, causing irritation.
Female horse flies feed on blood, while males seek nectar and sugary liquids. Horse flies are most active in warmer temperatures, but they are relatively resilient against strong air currents due to their size.
If a pet is constantly scratching due to fly irritation, it’s best to keep them indoors during warm, daylight hours when flies are most likely to feed. If flies are affecting a pet’s ears, consulting a veterinarian for treatment options is advisable.
3. Black Flies
Black flies thrive in moist environments around rivers and creeks and are identifiable by their humped backs when viewed up close. They are common throughout the United States but are especially prevalent in the northern regions. Black flies are known for their aggressive biting behavior, often targeting exposed skin.
4. Stable Flies
Stable flies are mainly found in late summer and early fall and primarily feed on livestock. They resemble house flies but have a pointed mouthpart used to suck blood. Stable flies are persistent biters and can cause significant annoyance to animals and humans alike. They are often found near farms and stables, where livestock provides a ready food source.
5. Snipe Flies
Snipe flies are closely related to deer flies and typically inhabit damp places in forested areas. While most species of snipe flies do not bite, some use their mouthparts to inflict irritating bites. Snipe flies are often found near water sources and are most active during daylight hours. Their bites can be painful and may cause localized irritation.
6. Sand Flies
Sand flies physically resemble drain flies and prey on mammals and reptiles. Adult sand flies are less than 1/8 inch in length, with long legs and wings that form a V shape. Sand fly bites are very painful. These tiny flies are known carriers of diseases such as leishmaniasis, making their bites a significant public health concern.
7. Yellow Flies
Yellow flies are primarily found in the southeastern U.S. and prefer shaded areas with forests and bodies of water. A yellow fly bite results in localized swelling and itching. These flies are most active during the warmer months and are known for their persistent biting behavior. Yellow flies are often found in areas with high humidity and dense vegetation.
8. Biting Midges
Biting midges, also called no-see-ums, rarely grow larger than 1/32 of an inch long, easily entering houses through window and door screens. This makes them one of the most pervasive biting flies. Biting midges are commonly found near the coast, where their larvae thrive in mud and can sometimes be seen swimming freely in infested waters. They breed in salt marsh areas and are susceptible to air currents, emerging most commonly on still days.
9. Mosquitoes
Mosquitoes are perhaps the best-known biting fly, biting more people each year than most other species combined. They are vectors of many diseases. Mosquitoes are notorious for transmitting diseases such as malaria, Zika virus, and West Nile virus, making them a significant public health threat worldwide.
10. Problems Caused by Flies That Bite
In addition to the pain caused by bites, flies can trigger allergies for many people. Certain species also spread diseases to humans. For example, mosquitoes can transmit West Nile and Zika viruses, while deer flies carry tularemia. Furthermore, biting flies can affect livestock by spreading illnesses and causing constant agitation, impacting their health and productivity.
According to research from Embry-Riddle Aeronautical University, in July 2025, controlling insect populations is becoming increasingly critical to prevent disease outbreaks, especially in areas with high human and animal populations.
11. Getting Rid of Biting Flies
The best way to control biting flies is to eliminate their optimal breeding conditions. Mosquitoes need water to lay eggs, so emptying containers and other items around the yard after rainfall will curb their numbers. Other types of biting flies may breed in rotting organic material, so prompt trash removal and cleaning of moist organic matter can help.
For comprehensive fly control, homeowners should contact professionals. Skilled professionals can identify biting flies and provide safe, reliable fly control solutions.
