The bacteria break down organic matter in the drain, such as food scraps and grease, and release hydrogen sulfide gas as a byproduct.

The smell is strongest when the water in the drain has been sitting for a while, such as overnight. A plumber can help you to identify the cause and recommend a solution, such as cleaning the drain, using specialized cleaning solutions, or installing a new ventilation system.
