Tips to Control Horse Flies

Horse flies are one of the world’s largest flies that are known for their painful bite, their natural habitat includes bogs, shallow lakes, swamps, brushy or low laying areas near streams, creeks ponds, saltwater marshes, and tanks that provide damp soils in which the immature stages develop. Horse flies prefer to fly in sunlight but avoid areas that are shady or dark, the adult flies are stronger fliers, the female usually lays her eggs on wet soil, or vegetation that overhangs the water or around large mammals for example deer, cattle, and horses.

Once the eggs hatch the larvae have the appearance of house fly maggots and are very active in moist or wet organic matter, the larva goes through an additional stage (pupal stage) before reaching adulthood. The lifecycle of these flies is 30-60 days.
