10 Best Mosquito Repellent Plants for Your Garden
Introduction
Summer evenings are made for backyard barbecues, stargazing, and family fun — not for swatting away mosquitoes! If you’re tired of chemical sprays and citronella candles, it’s time to go green. Certain plants naturally repel mosquitoes with their unique scents and oils, offering both beauty and protection for your garden. Whether you’re creating a cozy patio nook or a full-blown wellness garden, adding mosquito-repelling plants is an eco-friendly way to keep your outdoor space bug-free.
In this guide, we’ll introduce the 10 best mosquito repellent plants that thrive in U.S. gardens. These aren’t just effective — they’re also easy to grow, low maintenance, and attractive additions to any landscape. Let’s get buzzing (or better yet, un-buzzed)!
1. Citronella (Citronella Grass)
Citronella is one of the most effective mosquito-repellent plants, often used in candles and sprays. It emits a strong lemony scent that masks the smells mosquitoes use to find their targets. It’s a clump-forming grass that grows best in warm climates (Zones 9–11). This plant requires full sun, well-draining soil, and occasional watering once the topsoil dries. Citronella can be grown in large pots and brought indoors during cooler months. For best results, crush a few leaves to release oils. It’s attractive, low-maintenance, and perfect for patios, decks, or around seating areas in your garden.
2. Lavender
Lavender is a beautiful purple flowering herb that’s not only soothing to humans but also a natural deterrent for mosquitoes. Its strong fragrance disrupts mosquito sensory receptors, making it harder for them to locate you. Lavender thrives in full sun and dry, well-drained soil. It grows well in garden beds, borders, or containers. This hardy plant is drought-resistant and can also keep other pests like moths and flies away. Beyond its mosquito-fighting ability, lavender adds a relaxing aroma to your outdoor spaces. You can also use dried lavender inside your home for year-round mosquito defense.
3. Basil
Basil is a fragrant herb that’s both culinary and functional when it comes to repelling mosquitoes. The pungent oils in basil — particularly clove and cinnamon basil — emit a scent that mosquitoes avoid. Basil grows easily in full sun and moist, well-draining soil, and prefers regular watering. It’s ideal for container gardening on patios and windowsills. Unlike other mosquito-repellent plants, basil doesn’t need crushing to be effective. Plus, it gives you the bonus of fresh leaves for cooking. Grow basil near outdoor dining areas or doorways to keep bugs at bay while enhancing your garden’s aroma.
4. Marigolds
Marigolds are vibrant flowering plants known for their pest-repelling properties. They contain pyrethrum, a natural compound used in many commercial insect repellents. Their distinctive scent helps keep mosquitoes, aphids, and even nematodes at bay. Marigolds thrive in full sunlight and are incredibly easy to grow from seed or transplant. They do well in garden borders, raised beds, and containers. Deadheading (removing spent blooms) encourages continuous flowering throughout the season. These colorful flowers add a cheerful look to gardens while serving a protective function, making them perfect companions for vegetables and other ornamental plants.
5. Lemon Balm
Lemon balm is a citrus-scented herb in the mint family known for its mosquito-repelling qualities. The plant emits a strong lemony aroma that interferes with mosquito attraction. It grows best in USDA Zones 4–9 and prefers moist, well-drained soil with partial shade. Lemon balm can spread rapidly, so container gardening is often a good choice to control its growth. You can rub the leaves directly on your skin (after a patch test) to naturally repel mosquitoes. Besides warding off bugs, lemon balm also has calming properties and can be used in teas or herbal remedies.
6. Catnip
Catnip is a member of the mint family and is surprisingly powerful against mosquitoes. According to research, it’s even more effective than DEET in repelling them. The active compound, nepetalactone, irritates mosquitoes and drives them away. Catnip grows well in USDA Zones 3–9 and prefers full sun to partial shade. It’s a fast-growing, drought-tolerant plant but can become invasive, so pots are a great option. While cats love it, mosquitoes hate it — making catnip a fun and functional addition to your garden. Regular pruning will help it stay bushy and productive throughout the growing season.
7. Rosemary
Rosemary is a woody herb known for both its culinary uses and mosquito-repelling scent. The strong, pine-like aroma comes from its essential oils, which are effective against a range of insects, including mosquitoes. Rosemary thrives in USDA Zones 7–10 and prefers full sun and well-drained, sandy soil. It’s drought-tolerant and ideal for garden beds or containers. Burning a few rosemary sprigs in a firepit releases its oils into the air, naturally repelling bugs. Besides deterring mosquitoes, rosemary adds fragrance and beauty to any garden, and you can harvest it for seasoning year-round.
8. Peppermint
Peppermint is a fresh-smelling herb that mosquitoes, ants, and even spiders dislike. Its menthol-rich aroma is pleasant to people but deters insects by overwhelming their senses. Peppermint thrives in USDA Zones 3–11, prefers partial shade to full sun, and likes moist soil. It grows aggressively and is best planted in containers to prevent it from taking over your garden. You can crush peppermint leaves or extract oil to make natural sprays. In addition to being a pest repellent, peppermint can be used for tea, garnishes, and even homemade balms, making it a versatile garden favorite.
9. Scented Geraniums
Scented geraniums, especially those with lemon or citronella-like fragrances, are popular mosquito-repelling plants. They contain compounds that confuse mosquitoes and reduce their activity in the area. These plants thrive in USDA Zones 10–11 but are often grown as annuals or container plants in cooler regions. Geraniums prefer full sun, light soil, and moderate watering. Their attractive, colorful blooms and fragrant foliage make them ideal for patios, balconies, and sunny garden beds. During cold months, you can bring them indoors to keep them alive. Their dual purpose of beauty and bug defense makes them a great garden addition.
10. Bee Balm (Monarda)
Bee balm, also known as Monarda, is a flowering plant that repels mosquitoes with its strong minty fragrance. It’s especially loved by bees, butterflies, and hummingbirds — but not by biting insects! Native to North America, bee balm grows well in USDA Zones 3–9 and prefers full sun and moist, fertile soil. It spreads easily and creates vibrant red, pink, or purple blooms. To control its spread, divide the plant every couple of years. Bee balm adds a burst of color and pollinator activity to your garden while naturally keeping mosquitoes away.
