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 an EPA registered 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.
