Stable Fly Identification in South Florida
Stable flies are painful biting flies commonly found throughout South Florida, especially around livestock areas, coastal environments, animal facilities, beaches, lawns, and outdoor recreational spaces. These flies closely resemble house flies but feed on blood and are known for delivering painful bites to humans and animals, particularly around the legs and ankles. Stable flies are gray-colored flies with piercing mouthparts and aggressive daytime biting behavior. The scientific name for the stable fly is Stomoxys calcitrans, and they are also commonly referred to as biting house flies or dog flies.

What Are Stable Flies?
Stable flies are blood-feeding biting flies that thrive in warm humid environments with decaying vegetation, animal waste, and moisture.
Unlike house flies, stable flies bite humans and animals to feed on blood and are commonly associated with livestock areas, beaches, lawns, and outdoor animal environments.
These flies are strong daytime feeders and are especially active outdoors.
