The best way to eliminate all types of flies that live and breed in drains and garbage disposals. We destroy the fly's breeding and development habitat (known as drain scum or biofilm). The light gel clings to the walls of the pipes. It uses essential oils to kill and repel the flies and surfactants to clean the drain scum away. With no place to stay they go away.How to use: Simply pour 8 oz of product down the drain every 24 hours, until flies disappear. Use weekly as a prevention plan.
