1. What Exactly is a Fly?
A fly is a two-winged insect distinguished from most other winged insects, which typically have four wings. Flies possess specialized mouthparts adapted for either sucking liquids or, in the case of biting flies, piercing the skin to extract blood.
Flies are insects that belong to the order Diptera. According to research from the University of Florida, these insects are defined by having only two wings, while most other insects have four. Flies’ mouthparts vary; some are designed for sucking liquids, while others are adapted for piercing skin to draw blood. Biting flies use their specialized mouthparts to locate a host, pierce the skin, and ingest blood.
2. How Do Biting Flies Find Their Victims?
Biting flies locate humans and other animals through various sensory cues, including carbon dioxide and moisture in exhaled breath, dark colors, movement, warmth, and perspiration. These flies are attracted to the same cues that mosquitoes use to find their hosts.
Similar to mosquitoes, biting flies rely on a combination of sensory cues to locate their hosts. These cues include carbon dioxide and moisture present in exhaled breath, dark colors, movement, warmth emitted by the body, and perspiration. Once a fly detects these cues, it can quickly locate its target and initiate the biting process.
3. What Happens When a Biting Fly Bites?
When a biting fly lands on its target, it uses its piercing mouthparts to puncture the skin. It then injects saliva containing an anticoagulant to keep the blood flowing, allowing the fly to feed efficiently. This saliva can cause allergic reactions in sensitive individuals.
When a biting fly bites, it uses its specialized mouthparts to pierce the skin and inject saliva. This saliva contains an anticoagulant that prevents the blood from clotting, ensuring a steady flow of blood for the fly to ingest. According to a study from the National Institutes of Health, the saliva of biting flies can trigger allergic reactions in sensitive individuals, leading to itching, swelling, and discomfort.
4. Which Diseases Can Biting Flies Transmit?
Biting flies can transmit several debilitating diseases to humans and animals worldwide. Sand flies transmit diseases like sand fly fever, bartonellosis, and leishmaniasis. Deer flies in the United States can transmit tularemia. Biting midges can transmit diseases like blue tongue virus to livestock.
Biting flies pose a significant health risk due to their ability to transmit various diseases. Sand flies are known to transmit sand fly fever, bartonellosis, and leishmaniasis in many parts of the world. Deer flies in the United States can transmit tularemia, also known as “rabbit fever.” Biting midges can transmit diseases to livestock, such as the blue tongue virus.
5. How Can You Identify Different Types of Biting Flies?
Identifying biting flies is crucial to understanding the risks they pose and implementing targeted control measures. Common types of biting flies include deer flies, horse flies, stable flies, black flies, biting midges, and sand flies. Each fly has unique characteristics that can help with identification.
Identifying the specific type of biting fly is essential for understanding the potential risks and implementing appropriate control measures. Deer flies are medium-sized, yellow-brown to black flies with dark bands on their wings. Horse flies are larger, often with iridescent green eyes. Stable flies resemble house flies but have a pointed proboscis. Black flies are small, humpbacked flies. Biting midges are tiny and can penetrate window screens. Sand flies are small, hairy flies with wings that form a “V” shape at rest.
5.1. What Are Deer Flies and Horse Flies?
Deer flies are medium-sized flies, about ¼-inch long, typically yellow-brown to black with dark bands on their wings. Horse flies can be much larger, up to an inch or more, and are known for their strong, fast flight.
Deer flies and horse flies are closely related and belong to the family Tabanidae. Deer flies are smaller, about the size of a house fly, and are often found near streams, lakes, and marshes. Horse flies are larger and can fly long distances to feed on the blood of livestock and other animals. Both types of flies have scissor-like mouthparts that cut into the skin, causing a painful bite.
5.2. What Are Stable Flies?
Stable flies are about ¼-inch long and gray, with four dark stripes on their thorax. They look like house flies but have a pointed proboscis used to suck blood.
Stable flies, scientifically known as Stomoxys calcitrans, are commonly found in late summer and fall. They are known to fly several miles to bite livestock, pets, and people. Stable flies typically bite in the early morning or late afternoon, often attacking the ankles and inflicting a sharp, stabbing pain.
5.3. What Are Black Flies?
Black flies are small, no more than 1/8-inch long, with broad wings and a humpbacked appearance. They are often found near creeks and rivers.
Black flies, also known as buffalo gnats, thrive in moist environments and are often encountered near creeks and rivers. According to the University of New Hampshire Extension, black fly bites can cause considerable swelling, bleeding, and itching, and may be slow to heal. In large numbers, black flies can pose a threat to livestock and even humans due to allergic reactions and blood loss.
5.4. What Are Biting Midges?
Biting midges are tiny, no more than 1/32 of an inch long. They are also known as “punkies,” “no-see-ums,” or simply “gnats.” Their small size allows them to penetrate window and door screens.
Biting midges, belonging to the family Ceratopogonidae, are serious pests along the shores of oceans, lakes, ponds, and rivers. Their tiny size allows them to penetrate standard window and door screens, making them difficult to avoid. Biting midges can bite during the day or at night, causing itchy and irritating bites.
5.5. What Are Sand Flies?
Sand flies are long-legged, no more than 1/8-inch long, hairy, and brown to gray, with wings that form a “V” shape when at rest.
Sand flies are related to non-biting drain flies and are often found in moist, decaying plant matter. According to the Texas Department of State Health Services, sand flies are suspected of transmitting cutaneous leishmaniasis in some parts of the United States, including southern Texas. These flies typically feed on the blood of mammals, reptiles, and amphibians at night.
6. How Can You Manage Biting Flies in an Area?
Managing biting flies in a specific area involves sanitation, exclusion, and, in some cases, pesticide application. Area-wide control can be challenging due to the hidden habitats of larvae and the long distances some adult flies can travel.
Controlling biting flies requires a multi-faceted approach that includes sanitation, exclusion, and targeted pesticide application. Sanitation involves eliminating breeding sites by removing decaying vegetation and standing water. Exclusion involves using screens and netting to prevent flies from entering buildings. Pesticide application can be used to target both larvae and adult flies.
6.1. What Role Does Sanitation Play in Biting Fly Control?
Sanitation is crucial in controlling some biting flies. Removing decaying hay, straw, and other vegetation, including manure containing plant matter, can eliminate larval development sites for stable flies. Disposing of decaying vegetation can also control biting midges and sand flies.
Sanitation is a vital component of biting fly control. By eliminating breeding sites, you can significantly reduce the population of biting flies in your area. Stable flies, for example, breed in decaying hay, straw, and manure. Removing these materials eliminates their larval development sites. Biting midges and sand flies also breed in decaying vegetation, so removing this material can help control their populations.
6.2. How Can Exclusion Methods Help Prevent Biting Fly Bites?
Exclusion methods, such as installing and maintaining screens on windows and doors, can prevent stable flies from entering structures. However, standard household screens may not be fine enough to keep out the tiniest biting flies.
Exclusion methods are an effective way to prevent biting flies from entering your home or other structures. Installing and maintaining screens on windows and doors can keep out larger flies like stable flies. However, smaller flies like biting midges can penetrate standard household screens, so finer mesh screens may be necessary in areas where these flies are a problem.
6.3. Is Pesticide Application an Effective Way to Control Biting Flies?
Pesticide application can be used to control biting flies, but it has limitations. Ultra-low volume (ULV) treatments and space sprays are best used in areas where flies are numerous and concentrated. Residual pesticides can be used to spray surfaces where flies are resting.
Pesticide application can be a useful tool in controlling biting flies, but it should be used judiciously and as part of an integrated pest management strategy. ULV treatments and space sprays are effective for quickly reducing fly populations in a specific area. Residual pesticides can be applied to surfaces where flies are likely to rest, such as vegetation and walls. Larviciding, the application of pesticides to kill fly larvae, can be effective in controlling mosquito larvae and black fly larvae.
7. How Can You Prevent Biting Fly Bites on a Personal Level?
Preventing biting fly bites involves using repellents, avoiding areas inhabited by flies, avoiding peak biting times, and wearing protective clothing.
Preventing biting fly bites on a personal level involves several strategies: using repellents containing DEET or picaridin, avoiding areas where biting flies are prevalent, avoiding peak biting times when flies are most active, and wearing protective clothing such as long-sleeve shirts, long pants, and hats.
7.1. What Types of Repellents Are Effective Against Biting Flies?
Repellents containing the active ingredient DEET (N,N-diethyl-meta-toluamide) or picaridin are most effective against biting flies. While effective against mosquitoes, repellents may be less effective against some biting flies.
Repellents are a crucial line of defense against biting flies. According to the Environmental Protection Agency (EPA), repellents containing DEET or picaridin are effective against a variety of biting insects, including flies. However, some biting flies may be less susceptible to repellents than mosquitoes, so it’s essential to use repellents in combination with other preventive measures.
7.2. What Role Does Clothing Play in Preventing Biting Fly Bites?
Wearing heavy-duty, light-colored clothing, including long-sleeve shirts, long pants, and hats, can help prevent biting fly bites. Netting that covers the head can provide additional protection when black flies are numerous.
Protective clothing can significantly reduce your risk of being bitten by flies. Long-sleeve shirts and long pants create a barrier between your skin and the flies, making it more difficult for them to bite you. Light-colored clothing is less attractive to flies than dark clothing. Netting that covers the head, like the “bee bonnets” used by beekeepers, can provide additional protection when black flies are numerous and unavoidable.
7.3. Are There Other Methods to Prevent Biting Fly Bites?
Other methods to prevent biting fly bites include avoiding areas inhabited by flies, avoiding peak biting times, and using fans to keep small areas free of flies. Smaller biting flies may become stuck in heavy coatings of lotions or oils applied to the skin.
Additional methods to prevent biting fly bites include avoiding areas where flies are prevalent, especially during peak biting times in the early morning and late afternoon. Fans can help keep small areas free of flies, especially smaller species whose flight is affected by air currents. Applying heavy coatings of lotions or oils to the skin may also deter smaller biting flies like biting midges.
