Common house flies are attracted to decaying organic matter, trash, and moist, rotting food, often entering homes to find food and breeding sites. 

Causes of House Fly Infestation

  • Decaying Organic Matter: The primary cause is rotting food, meat, garbage, or feces, which provides breeding material for larvae (maggots).
  • Poor Sanitation & Food Access: Uncovered food, dirty dishes, spilled liquids, or overripe fruit attracts flies.
  • Easy Access Points: Ripped window screens, open doors, or cracks in walls allow flies to enter.
  • Moisture Sources: Standing water, leaky drains, or wet organic waste (like pet waste or lawn clippings) creates ideal breeding environments.
  • Deceased Animals: Dead rodents or birds in walls or chimneys can cause a sudden, massive infestation. 

Solutions and Prevention

  • Sanitation (Deep Clean):
    • Dispose of trash daily in tightly sealed containers.
    • Clean garbage bins regularly to remove residue.
    • Clean up pet waste immediately.
    • Keep food in airtight containers and wipe surfaces clean.
  • Exclusion (Keep Them Out):
    • Install and repair screens on doors and windows.
    • Use air curtains or fans near entrances.
  • Environmental Management:
    • Clean drains to prevent maggots.
    • Reduce outdoor lighting at night to deter them from gathering.
