Summer evenings in the garden are magical—until mosquitoes crash the party. Instead of relying on chemical sprays, why not let nature do the work?
There are fragrant plants that repel mosquitoes effectively while also bringing color, aroma, and charm to your garden or patio. I discovered this when I placed pots of lavender and basil on my balcony last year. The air smelled wonderful, and the number of mosquitoes buzzing around dropped noticeably.
Let’s explore some of the most effective plants that repel mosquitoes and how they can transform your outdoor spaces.
1. Lavender – The Classic Mosquito Repellent
The soothing scent of lavender is loved by humans but hated by mosquitoes. Rich in natural oils like linalool, lavender disrupts the mosquito’s ability to smell and find you.
Whether grown in pots or garden beds, lavender thrives in sunny spots. In my own experience, keeping dried lavender bundles near windows also helped reduce indoor mosquito activity.
2. Marigolds – Bright, Cheerful, and Effective
Few plants are as hardworking as marigolds. These cheerful orange and yellow flowers release a compound called pyrethrum, commonly used in insect repellents.
Marigolds are easy to grow, low-maintenance, and perfect for borders around patios or vegetable gardens. Not only do they deter mosquitoes, but they also keep away aphids and whiteflies.
3. Citronella Grass – Nature’s Mosquito Candle
When you think of mosquito repellents, citronella grass is probably the first thing that comes to mind. Unlike candles, the live plant is even more effective.
By crushing its leaves, you release citronella oil, a proven mosquito deterrent. I’ve often rubbed a leaf on my arms during evening walks in the garden, and the difference was instant.
4. Basil – A Herb with a Hidden Power
Everyone knows basil adds flavor to pasta and salads. But fewer people know that Basil will repels mosquitoes naturally.
Unlike many herbs, basil releases its aroma continuously, without needing to be crushed. Growing basil in pots near your doorways not only keeps mosquitoes out but also ensures you always have fresh leaves for cooking.

5. Rosemary – Strong Aroma, Strong Defense
The woody fragrance of rosemary is delightful in cooking but intolerable to mosquitoes. This herb grows well in pots and thrives in warm, sunny conditions, making it a favorite in North America.
Placing rosemary near barbecues is a smart move. The smoke from burning a few sprigs adds flavor to your food while keeping mosquitoes at bay.
6. Scented Geraniums – The Decorative Defender
Scented geraniums are striking, decorative plants with a lemony fragrance that mosquitoes dislike. Their leaves contain citronella compounds, similar to citronella grass.
They make excellent balcony or porch plants, offering beauty, fragrance, and pest protection all in one.
7. Catnip – A Surprising Mosquito Fighter
Yes, catnip isn’t just for cats. Research from Iowa State University found that catnip oil is ten times more effective than DEET at repelling mosquitoes.
It’s easy to grow, spreads quickly, and doubles as a treat for your feline friends—just be prepared for extra visits from neighborhood cats.
8. Mint, Oregano, Thyme, and Lemon Balm – The Aromatic Shield
- Mint: Peppermint especially is known to repel mosquitoes with its sharp menthol scent.
- Oregano: Not just for pizza lovers—oregano plants naturally ward off insects.
- Thyme: When burned, thyme releases compounds toxic to mosquitoes.
- Lemon Balm: Its lemony aroma makes it both refreshing and protective.
I keep pots of mint and lemon balm near my garden seating area. They smell fresh and instantly make evenings outdoors more comfortable.
