What Flies Bite Humans? Biting flies, as explained by flyermedia.net, seek blood for sustenance, targeting both humans and animals, and some can even transmit diseases. Dealing with these pests requires understanding their types, the problems they cause, and how to effectively manage them, which are all explored on this page.
1. What are the Most Common Types of Flies That Bite Humans?
Several types of flies bite humans, each with distinct characteristics. Here’s a detailed look:
- Deer Flies: Emerging in spring, Deer flies use scissor-like mouthparts to inflict painful bites. Deer flies are smaller than house flies, and their bites are known for being particularly irritating due to the way they slice the skin.
- Horse Flies: Similar to deer flies, horse flies cut into the skin, causing pain and swelling. The large size of horse flies can be intimidating, and their bites are considered among the most painful due to their size and aggressive biting behavior.
- Black Flies: These flies thrive in moist environments near rivers and creeks. Black flies are identified by their humped back and are prevalent across the United States, particularly in the northern regions.
- Stable Flies: These flies primarily target livestock but will also bite humans, particularly in late summer and early fall. Stable flies resemble house flies but have a pointed mouthpart for sucking blood.
- Snipe Flies: Closely related to deer flies, snipe flies inhabit damp, forested areas. While most species don’t bite, some can inflict irritating bites.
- Sand Flies: Similar in appearance to drain flies, sand flies prey on mammals and reptiles. Adult sand flies are small (less than 1/8 inch) with long legs and V-shaped wings, and their bites are notably painful.
- Yellow Flies: Predominantly found in the southeastern U.S., yellow flies prefer shaded areas with forests and water. A yellow fly bite results in localized swelling and itching.
- Biting Midges (No-See-Ums): These tiny flies (rarely larger than 1/32 inch) can easily enter homes through screens, making them pervasive biters. Biting midges are commonly found near the coast, and their larvae thrive in mud, often seen swimming in infested waters.
- Mosquitoes: Perhaps the most well-known biting fly, mosquitoes bite more people annually than other species combined and are vectors of numerous diseases. Mosquitoes require water to lay their eggs, making standing water a key breeding ground.
Understanding these different types of flies is the first step in effectively managing and preventing bites. According to the National Pest Management Association (NPMA), identifying the specific type of biting fly can help tailor control strategies for better results.
2. What Problems Do Biting Flies Cause Besides the Initial Bite?
Beyond the immediate pain and irritation, biting flies can cause a range of problems. Understanding these issues is crucial for taking preventive measures.
- Allergic Reactions: Some individuals experience allergic reactions to fly bites, leading to more severe itching, swelling, and discomfort. In rare cases, severe allergic reactions may require medical attention.
- Disease Transmission: Various biting flies can transmit diseases to humans and animals. Mosquitoes are known carriers of diseases like West Nile virus, Zika virus, and malaria. Deer flies can transmit tularemia, while sand flies can carry leishmaniasis.
- Secondary Infections: Scratching bites can lead to secondary bacterial infections. Broken skin provides an entry point for bacteria, resulting in redness, pus, and increased pain.
- Livestock Impact: Biting flies can significantly affect livestock health and productivity. Constant agitation from fly swarms can cause stress, reduced feeding, and decreased weight gain in cattle and horses. Additionally, flies can transmit diseases to livestock, impacting agricultural economies.
- Economic Impact: The presence of biting flies can negatively impact tourism and outdoor recreational activities. Areas with high fly populations may see a decline in visitors due to the nuisance and health risks.
According to the Centers for Disease Control and Prevention (CDC), preventing bites is the best way to reduce the risk of disease transmission and other health issues associated with biting flies.
3. Where Do These Flies Typically Breed and Live?
Understanding the breeding and living environments of biting flies is essential for effective control and prevention.
- Deer Flies: Deer flies thrive in marshy areas, woodlands, and near bodies of water. They lay their eggs in moist soil or vegetation near these habitats.
- Horse Flies: Horse flies also prefer marshy and damp environments, laying their eggs near water sources. They are often found in rural and agricultural areas.
- Black Flies: Black flies require flowing water to breed, making rivers and streams their primary habitat. The larvae attach to rocks and vegetation in the water.
- Stable Flies: Stable flies breed in decaying organic matter, such as manure, rotting hay, and compost. They are commonly found around livestock facilities and agricultural settings.
- Snipe Flies: Snipe flies prefer damp, forested areas, where they can find the moist soil and decaying matter necessary for their larvae to develop.
- Sand Flies: Sand flies breed in moist, sandy areas, often near vegetation and animal burrows. They are prevalent in tropical and subtropical regions.
- Yellow Flies: Yellow flies inhabit shaded, forested areas with nearby water sources. They are particularly common in the southeastern United States.
- Biting Midges (No-See-Ums): Biting midges breed in salt marshes, mud, and other wet environments. Their larvae can be found in standing water, mud, and decaying vegetation.
- Mosquitoes: Mosquitoes breed in standing water, including puddles, containers, and natural bodies of water. Different species have varying preferences for water quality and habitat.
The University of Florida’s Entomology Department notes that eliminating breeding sites is a critical step in managing biting fly populations.
4. How Can I Protect Myself from Biting Flies Outdoors?
Protecting yourself from biting flies outdoors involves several strategies to minimize exposure and prevent bites.
- Use Insect Repellents: Apply insect repellents containing DEET, picaridin, IR3535, or oil of lemon eucalyptus (OLE) on exposed skin. Follow the product instructions carefully, and reapply as needed. The Environmental Protection Agency (EPA) provides a tool to help choose the right repellent for your needs.
- Wear Protective Clothing: Wear long sleeves, long pants, and socks when possible, especially during peak biting times. Light-colored clothing can also help deter some species of flies.
