To get rid of gnats in your apartment, use sticky traps or vinegar traps, and eliminate moisture and food sources. Cleaning up spills and keeping trash bins closed will prevent them from breeding.

Gnats are often drawn to food and moisture in apartments. Setting up traps using vinegar or sticky tape will help catch them. Reducing moisture by fixing leaks and cleaning up food waste will prevent them from laying eggs. Keeping kitchen areas clean and taking out the trash regularly will reduce the likelihood of a gnat infestation. For severe problems, insecticides may be required.
