Face Flies

Category: Flies

Scientific Name: Musca autumnalis



Color: Dull gray in color

Important Considerations:

  • The Face Fly gets its name because it feeds on the mucus and secretions found around a cow’s eyes, mouth and nose.
  • They will overwinter inside of homes and structures. They will go back to the same structures every year.
  • These flies lay their eggs in fresh cow manure.


Where to Find Them on Your Property?

Once inside a house or structure, face flies like to hangout in wall voids, attics or basements. They are also attracted to lights and will swarm a light or hang out around windows.
