Fly Control and Prevention

Small fly control requires a partnership between you and your pest provider. Since small flies are an indicator of a sanitation or structural problem within your facility, removal of the breeding source is the only permanent means of avoiding an infestation. Following simple sanitation and structural recommendations can make a big difference in avoiding a fruit fly infestation.

Fly Control and Prevention

By following the simple sanitation and structural recommendations listed below you can make a big difference in avoiding a fruit fly infestation.
  • Inspect incoming fruits and vegetables for signs of rot and small flies, and cover them upon receipt.
  • Store produce under refrigeration when possible, or in sealable plastic tubs.
  • Rinse out empty bottles and cans, and clean garbage containers daily. Use plastic liners.
  • Keep garbage areas clean and away from the building when possible; close receptacles with tight-fitting covers.
  • Keep the exterior dumpster pad free of spillage and debris.
  • Repair areas damaged by water.
  • Eliminate standing water, weeds, and tall grass near the facility.
  • Clear clutter and items stored on the ground.
  • Inspect, seal, and maintain doors in good condition. Keep doors closed, or use double-door vestibules, air doors, or plastic strip doors where needed.
  • Install 20 mesh screens on any open windows.
  • Eliminate interior standing water and accumulated condensation, and use fans in areas conducive to standing water.
  • Replace cracked floor tiles and missing grout, and repair plumbing and drain problems.
  • Regularly inspect for and repair cracks in flooring to prevent seepage below.

Sanitation issues are a major contributor to small fly problems. Make sure your staff is:

  • Cleaning and sanitizing floors and around drains, disposals, and sinks daily:
    • Inspect and sweep thoroughly under appliances, counters, and cook lines.
    • Scrub floors using a stiff brush with an industrial floor cleaner. Squeegee all debris and dispose of in the trash; do not dispose of organic debris in drains.
    • Mop the floor using a sanitizer approved for food and non-food surface application.
  • Cleaning drains weekly
    • Clean drains and traps using an industrial drain cleaner and a stiff long-handled brush.
    • Use a “snake” device in clogged drains to clean out all gelatinous material.
  • Disposing of rotting organic matter.
  • Performing periodic deep cleaning beneath lines and equipment.
  • Cleaning rags and mop heads daily and before storing.

If flies persist after a thorough cleaning, Ecolab can help with treatment and ongoing protection.

Small Flies and Food Safety

Although the fruit fly (also known as a small fly) has historically been considered a nuisance pest, recent research proves that small flies contaminate food with bacteria carried from unsanitary surfaces (such as trash, drains, mops, etc.).
