How to Use a Fly Killer Indoor Effectively
-
Placement matters: Put your trap near fly entry points (like doors or sinks) and away from bright competing lights.
-
Turn it on before sunset: Flies are most active during dusk and are attracted to light.
-
Replace glue cards regularly: Dirty or full glue pads reduce catch rates.
-
Keep it plugged in: For plug-in traps, 24/7 operation yields best results.
-
Don’t block airflow: Keep the trap's vents exposed and upright.
