Stable flies are small, blood-feeding insects that belong to the family Muscidae. They are commonly found in agricultural areas, particularly around livestock, where they feed on the blood of animals like cattle and horses. Stable flies are about 6 to 8 millimeters long and have a distinctive pattern of gray and black on their bodies. These flies are known for their painful bites, which can cause stress and discomfort to animals. They are also considered pests because they can reduce the productivity of livestock and transmit diseases. Effective management strategies include maintaining clean environments and using insecticides when necessary.
