Treat deer fly bites by cleaning the affected area with soap and water, according to Real Simple. For pain, apply ice to the area in 15-minute intervals throughout the day. If needed, an over-the-counter bug-bite remedy helps to quell the pain and prevent scratching, which can lead to a secondary infection.

Deer flies can transmit a rare bacterial infection called tularemia, or rabbit fever, according to Healthline. This infection causes skin ulcers, headaches and fevers and can be fatal if left untreated. Tularemia is treatable using antibiotics.
Deer flies are typically about a 1/4 to 1/2 inch long and tend to live near lakes, swamps and pools, according to Healthline. The wings of deer flies have brown and black bands on them, and the flies often have green or yellow eyes.
Deer flies can be avoided by spraying the body and clothing with insect repellent containing Deet when the flies are present, according to the University of Kentucky College of Agriculture, Food and Environment. In most areas, deer flies are only a problem for small stretches throughout the summer months and typically only feed during the day.
