Review fly activity, waste handling, entry routes and the requirements of your premises.
Request an assessmentDifferent flies point to different site conditions. Repeated activity around bins, food handling or damp organic material needs a different investigation from an occasional insect entering through a doorway.
Identifying the fly and locating its source helps separate breeding within the premises from insects arriving outside. In operating spaces, waste routines, cleaning access and door management are part of that investigation.
Record the fly's appearance, the time and location of peak activity and the waste or drainage conditions nearby. The assessment compares likely breeding material with the building's entry routes and cleaning responsibilities.
Keep agreed waste and cleaning routines consistent, including the areas around and beneath bins. Arrange repairs to entry screens, doors or drainage where these form part of the plan.
Compare activity at the same locations over time. A continuing source may need a maintenance change rather than repeated treatment of visible adults.
No. Fly identification and the material available on site help narrow down the source; location alone is not enough.
Monitoring or capture can help track activity, but the material supporting development still needs to be addressed.
