Equine fly protection refers to measures taken to protect horses from various species of flies that may bite, irritate, or transmit diseases. Fly protection can be achieved in a number of ways, including the use of fly repellent sprays, fly sheets, fly masks, and protective boots. Some fly repellents are applied directly to the horse's coat, while others are sprayed onto the surrounding environment to keep flies at bay. Fly sheets and masks are designed to cover the horse's body and head, respectively, and can also provide UV protection. Fly boots are designed to cover the horse's lower legs and prevent flies from biting in this area. Overall, proper fly protection is an important component of equine health and welfare, as fly bites can cause discomfort, skin irritation, and in some cases, transmit serious diseases.
