Site Survey

  • Start outside the building – Note the most likely sources of insects – i.e. breeding sites such as dumpsters, drainage, farms etc.
  • Walk from outside to the inside of the building – a. Establish the likely entry points for flying insects – b. Determine the natural path the insects might take as they move through the building – c. Consider how windows, doors, lighting and air movement might guide insects along.
  • Grade the areas of the building according to level of risk – low, medium and high.
  • Define front and back of house areas that need flying insect control equipment.
  • Plan the specific locations for Insect Light Traps.

General Placement Guidelines

  • It is recommended that ILTs are wall mounted 6.5ft (2m) from the ground, the typical height of a fly’s flight path, and where they can be easily accessed to be serviced.
  • ILTs should not be positioned where they may be damaged e.g. in passageways, in the way of maintenance staff or fork lift trucks.
  • Position ILTs so that they intercept flies before they can enter critical areas.
  • Position ILTs so that insects are drawn away from the area that is being protected.
  • Do not place ILTs over food preparation, packaging or processing areas.

ILT Maintenance

  • Replace consumables regularly
  • Glue boards should be changed every four weeks.
  • Lamps should be changed every 12 months prior to peak insect season in Spring.
  • Keep ILTs clean and free from debris by servicing and cleaning them on a regular basis.
