9 Plants That Double as Natural Mosquitoes Repellents

 Summer evenings in the garden feel magical—until the buzzing sound of mosquitoes ruins the vibe. Instead of depending on harsh sprays or electric repellents, why not rely on nature’s own defense system?

There are fragrant plants that repel mosquitoes effectively while making your garden greener, more colorful, and beautifully aromatic. I discovered this last year when I added pots of lavender and basil to my balcony. The air smelled heavenly, and the number of mosquitoes went down instantly.

Here’s a complete guide to the best plants that repel mosquitoes and how you can use them to make your garden safer and more inviting.

1. Lavender – The Classic Mosquito Repellent

The soothing fragrance of lavender may calm humans, but mosquitoes hate it. Its natural oils, especially linalool, interfere with the mosquito’s sense of smell.

Lavender grows best in sunny spots, whether in pots or directly in garden beds. Even dried lavender bundles near windows can keep mosquitoes away indoors. Apart from being practical, the purple blooms add elegance and calmness to any outdoor corner.

2. Marigolds – Bright, Cheerful, and Effective

Marigolds are more than just pretty flowers. They produce a compound called pyrethrum, which is a key ingredient in many insect repellents.

These flowers are easy to grow, low-maintenance, and ideal for lining pathways, vegetable gardens, or patio borders. They not only deter mosquitoes but also keep aphids, whiteflies, and other pests away. Truly one of the hardest-working flowers in the garden.

3. Citronella Grass – Nature’s Mosquito Candle

When someone mentions mosquito repellents, citronella grass is usually the first name that comes to mind. Unlike citronella candles, the live plant is far more effective.

Crushing its leaves releases citronella oil, which is well-known as a mosquito deterrent. I often rub a crushed leaf on my arms before sitting outdoors in the evening—it’s simple, natural, and effective.

Growing citronella in pots near seating areas or garden walkways ensures mosquitoes keep their distance.

4. Basil – A Herb With a Secret Superpower

Most people know basil as a flavorful herb for pasta and salads. But here’s the hidden fact: Basil will repels mosquitoes.

Unlike other herbs, basil gives off its strong aroma continuously—even without crushing the leaves. That means you get double benefits: a natural repellent and fresh leaves for your recipes.

Keeping pots of basil near kitchen doors or windows is one of the easiest and most effective ways to keep mosquitoes out.

5. Rosemary – Strong Aroma, Strong Defense

The woody, earthy fragrance of rosemary is delightful for humans but unbearable for mosquitoes. This herb thrives in sunny conditions and is perfect for pots on patios or balconies.

Pro tip: Place rosemary near your barbecue. Not only will it keep mosquitoes away, but tossing a few sprigs onto the coals adds incredible flavor to grilled food.

6. Scented Geraniums – Decorative and Protective

Scented geraniums are as beautiful as they are functional. Their lemony fragrance comes from citronella-like compounds in their leaves, making them excellent mosquito deterrents.

These plants are highly decorative, making them a favorite for balconies and porches. You get color, fragrance, and mosquito protection in one lovely package.

7. Catnip – Surprisingly More Effective Than Chemicals

We usually associate catnip with playful cats, but research shows it’s also a powerful mosquito repellent. In fact, scientists at Iowa State University found catnip oil to be up to ten times more effective than DEET, one of the strongest chemical repellents.

Catnip is hardy, grows quickly, and spreads easily. If you have cats at home, they’ll love it too—though you may attract a few neighborhood cats as well!

8. Mint, Oregano, Thyme, and Lemon Balm – The Aromatic Shield

• Mint: Especially peppermint, is effective against mosquitoes thanks to its menthol-rich scent.
• Oregano: Adds taste to dishes while keeping bugs away.
• Thyme: Burning thyme releases compounds toxic to mosquitoes—great for campfires.
• Lemon Balm: Known for its lemony aroma that mosquitoes can’t tolerate.

I keep small pots of mint and lemon balm near my outdoor seating area. Not only do they smell refreshing, but they also create a mosquito-free comfort zone.

9. Bee Balm – Beauty With a Purpose

Also called Monarda, Bee Balm is a striking plant with bright flowers that attract pollinators like bees and butterflies. But here’s the bonus: it also helps keep mosquitoes away.

Planting bee balm in the center of your garden makes it both a functional and aesthetic choice.
