Horse fly

Horse flies are large, robust flies, typically 3/4 to 1 1/4 inches long. They are characterized by their large, iridescent eyes and piercing-sucking mouthparts. Their coloration ranges from gray to dark brown, with some species having banded abdomens.

While horse flies don't infest homes, their presence is noticeable due to their painful bites, especially during daylight hours. Look for them in areas with standing water or near livestock, as these are common breeding grounds. Increased activity around your property, especially near the Waccamaw River or Intracoastal Waterway, may indicate a larger local population.

Due to their wide-ranging habits, direct treatment of horse flies is challenging. MBPC can advise on habitat modification strategies to reduce breeding sites. For properties with severe horse fly issues, area fogging treatments can provide temporary relief, but must be conducted by licensed applicators per SC Department of Pesticide Regulation guidelines.

Wear long sleeves and pants when spending time outdoors, especially during peak horse fly season in Myrtle Beach. Use insect repellent containing DEET or picaridin. Eliminate standing water around your property to reduce breeding sites. Consider using fly traps or screens to minimize horse flies near your home or stables.

Horse flies thrive in the humid subtropical climate and coastal environment of Myrtle Beach, SC. They are commonly found near marshes, swamps, and other bodies of water, where the females lay their eggs. Larvae develop in moist soil or shallow water, making coastal areas with salt marshes and tidal creeks ideal breeding grounds.
