They are known to consume large amounts of blood, and transmit viruses, bacteria or other microorganisms.
How Do Horse Flies Affect Horses? In an attempt to avoid being bitten, horses will become irritable and distracted. In addition, horse flies are the main carriers of “Equine Infectious Anemia (EIA), sometimes referred to as swamp fever, is common in the southeastern US and is mechanically (on the body of the fly) transmitted to horses and other equids. It is a viral disease that causes lethargy, weight loss, and sometimes death in an affected animal. There are two strains of the virus; one is more intense than the other. An acutely infected horse almost always dies quickly. A chronically infected horse will eventually die of complications or unapparent carriers may live without obvious health problems,” according to an article posted on the Texas A&M Agrilife Extension website.*
