Peppermint has a strong aroma and toxicity. That is why it is effective in repelling gnats. Once these insects get a whiff of peppermint oil, they’ll instantly leave the area.

If you want to make your own natural repellent spray, mix peppermint oil with water in a spray bottle and spread the smell in gnats-infested areas. Or you can buy pre-made ones in stores.

2. Lavender Oil

Another essential oil that is pleasant to smell but can get rid of gnats is lavender. It’s an essential oil used by some in aroma therapies. But its strong, floral scent can also repel gnats. But it will not kill them.

3. Thyme Oil

Gnats also don’t like the strong scent of thyme.

There are plenty of dishes that use thyme as a recipe. And you can easily grow some in your home. You can use the fragrant scent of thyme oil to repel gnats and for cleaning to make your home smell nicer.

4. Lemon Oil

You may find it in air fresheners and cleaning sprays. But lemon oil is also great for keeping gnats away from your home, especially your indoor plants. So your home will not only smell lemony-fresh but also gnat-free.

5. Geranium Oil

If you want your home to smell like flowers, you can use geranium oil to keep gnats at bay and away from your home. The strong floral scent will keep your home smelling fresh while actively repelling gnats.

This essential oil is a great option for those who want to bring spring to their homes.

Citronella oil is also great for repelling gnats. You can even buy candles that have citronella in them to repel other flying insects like mosquitoes. That is why most people are reminded of summer when they smell citronella because they bring citronella-scented candles when they camp.
