To get rid of gnats in your room, use sticky traps or vinegar traps, and reduce moisture levels. Cleaning up food or drink spills and keeping windows and doors closed will prevent them from entering.

Gnats can enter rooms through open windows or doors, especially if there is food or moisture present. Sticky traps or vinegar traps placed near the infestation will help catch them. Reducing moisture levels by fixing leaks or using dehumidifiers will discourage gnats from breeding. Ensuring windows and doors are closed or installing screens will prevent them from entering your room.
