Fly Masks

Dr. Timothy Gibb, Clinical Professor of Entomology at Purdue Agricultural University in Indiana, explained: “Fly masks are used to relieve the stress that a horse deals with when continually fighting flies – primarily the face fly. Face flies are persistent and annoying while they feed around the eyes and nose of horses. They are capable of transmitting eye-worm to horses but this is not common. The mask simply acts as a physical barrier between the horse and the flies.
