Signs of Drain Fly
What to look for🔎Signs of infestation and damage
Swarms around waste, drains or food-prep areas, fly specks (small dark dots) on walls and ceilings near resting/breeding sites, and — critically — an increased risk of food contamination in kitchens and food-handling areas.
How Drain Fly is controlled
Integrated approach🧪Control methods
Control starts with removing breeding sites (waste management, drain cleaning, moisture control) and screening doors and windows, backed by a PCO's fly-control programme — light traps, space treatment and residual treatment of resting surfaces — for persistent infestations.

Can I treat Drain Fly myself, or do I need a professional?
