The stable fly is a blood-sucker that looks like a house fly but has a piercing-type mouthpart that projects forward from the front of its head.
Males and females feed on warm-blooded animals and humans, usually around the lower leg or ankles. They will also attack dogs, biting them mostly on the ears.
Stable flies are not limited to barns and stables; they will rest around houses and attack people, too. Stable flies are strong fliers; they can cause problems at least two miles from their breeding sites.
