Protecting Chickens from Killer Black Flies: Buffalo Gnats

Backyard chicken keepers don’t typically think of insects as predators, but certain flies within the Simuliidae family can be every bit as deadly to chickens as a fox or hawk. Also known as buffalo gnats and turkey gnats, these tiny, biting flies, which may attack victims in swarms, are a painful nuisance to humans, but a deadly threat to animals. Knowing when they attack is the key to guarding backyard chickens against their onslaught.

Despite their name, black flies can be a variety of colors, but you’ll know when they’re in your area as they make enjoying the out-of-doors impossible. The females inflict painful bites, drawing blood from their victims while injecting a toxic saliva cocktail that causes itching, swelling and worse.
