Arizona’s diverse landscapes, ranging from desert to mountainous regions, are home to a wide variety of biting fly species. These flies are not only a nuisance but can also pose significant health risks to humans and animals through the transmission of diseases. Understanding the different types of biting flies, their habits, and the threats they pose is crucial for residents and visitors alike to take appropriate preventive measures.
Horse Flies
Horse flies are among the most common and bothersome biting flies in Arizona. They are known for their painful bite, which can draw blood and cause significant discomfort. Horse flies are attracted to dark colors, movement, and the carbon dioxide emitted by animals and humans. They are most active during the warmer months and are typically found near water sources, as they lay their eggs in moist environments.
Deer Flies
Deer flies, similar to horse flies, are also known for their painful bites. These flies are smaller than horse flies but can be just as bothersome. Deer flies are attracted to light colors, especially white and other bright shades, which can make them a particular nuisance for people wearing these colors outdoors. They are also active during the warmer parts of the day and are found in areas with standing water, where they can lay their eggs.
Sand Flies
Sand flies, although smaller and less noticeable than horse and deer flies, can still cause significant discomfort through their bites. They are more active at dawn and dusk and are attracted to the carbon dioxide and heat emitted by warm-blooded animals. Sand flies can transmit diseases such as leishmaniasis, making them a significant health concern in certain regions of Arizona.
Black Flies
Black flies, also known as buffalo gnats, are another type of biting fly found in Arizona. Their bites can be extremely painful and may cause swelling and itching. Black flies are typically found near moving water, where they lay their eggs, and are most active during the spring and early summer.
Health Risks
Biting flies in Arizona can transmit various diseases and pathogens, posing a significant health risk to humans and animals. Leishmaniasis, a disease transmitted by sand flies, can cause severe health issues, including skin lesions, fever, and in severe cases, organ damage. Horse flies and deer flies can also transmit diseases, although the risk is generally lower compared to sand flies.
Prevention Measures
To minimize the risk of bites from these flies, several preventive measures can be taken:
- Wear Protective Clothing: Wearing long sleeves, long pants, and using insect repellents can significantly reduce the risk of bites.
- Avoid Peak Hours: Staying indoors during peak fly hours, usually around dawn and dusk for sand flies and during the warmest parts of the day for horse and deer flies, can help avoid bites.
- Remove Standing Water: Eliminating standing water around homes and yards can reduce the breeding areas for these flies.
- Use Screens: Installing screens on windows and doors can prevent flies from entering homes.
- Insect Repellents: Using insect repellents containing DEET, picaridin, or oil of lemon eucalyptus can provide protection against biting flies.
Management and Control
For areas heavily infested with biting flies, professional management and control methods may be necessary. This can include the use of insecticides, biological control methods, and traps designed specifically for the type of fly. However, these methods should be used judiciously and in accordance with local regulations to avoid harmful environmental impacts.

By understanding the behaviors of these flies and taking proactive measures to prevent bites, individuals can enjoy the outdoors with reduced risk.
