1. Lavender

this idea

Lavender is one of the most beloved mosquito repellent plants, prized for its calming scent and gorgeous purple flowers. But beyond its beauty, lavender gives off an aroma that mosquitoes can’t stand. The secret lies in its essential oils, which are most concentrated in the leaves and flowers. These oils may even impair a mosquito’s ability to smell.

Lavender thrives in full sun and well-drained soil, making it a low-maintenance addition to any garden. It’s also drought-tolerant once established and does well in borders, containers, or as a fragrant hedge. Not only does lavender keep pests away, but it also attracts pollinators like bees and butterflies, creating a balanced and vibrant garden space.

Quick Tips:

• Type: Perennial
• USDA Zones: 5–11 (varies by variety)
• Best Location: Sunny, dry areas near patios or walkways

2. Marigold

Marigolds are bright, cheerful flowers that double as powerful mosquito repellent plants. Their strong, distinct scent helps keep mosquitoes, whiteflies, aphids, and other common garden pests at bay. This makes them a smart and attractive choice for both ornamental beds and vegetable gardens.

Marigolds are easy to grow and thrive in pots, raised beds, or along borders. Place them near windows, doorways, or patios where people tend to gather. Not only will you enjoy their sunny blooms, but you’ll also benefit from a natural mosquito barrier.

These annuals bloom from late spring through the first frost, bringing color and protection throughout the growing season.

Quick Tips:

• Type: Annual
• Bloom Time: Late spring to frost
• Best Location: Containers, entryways, garden borders

3. Citronella Grass (Lemongrass)

Citronella grass, often called lemongrass, is one of the most widely recognized mosquito repellent plants. Its citrusy aroma is the same scent used in many commercial repellents—and for good reason. The living plant is even more effective at keeping mosquitoes away than synthetic sprays.

This tropical grass prefers warm, sunny conditions and grows best in large containers or directly in the ground in frost-free zones. In cooler climates, it can be grown as an annual or brought indoors during the winter. Its tall, graceful blades make it a striking addition to patios, decks, and poolside gardens.

Quick Tips:

• Type: Tender perennial, often grown as an annual
• USDA Zones: 9–11
• Best Location: Large pots or sunny garden spots

4. Catmint

Catmint, a close relative of catnip, is not only a hardy and attractive perennial—it’s also one of the most effective mosquito repellent plants you can grow. Its soft lavender-blue flowers and fragrant, silvery foliage add beauty to borders and walkways, while naturally driving mosquitoes away.

Research has shown that catmint can be up to ten times more effective than DEET, the chemical found in many insect repellents. It’s incredibly easy to grow, often thriving with minimal care. However, it spreads quickly, so regular pruning may be needed to prevent it from taking over your garden.

Quick Tips:

• Type: Perennial
• USDA Zones: 3–8
• Bloom Time: Early summer through fall
• Best Location: Borders, containers, or wildflower gardens

5. Rosemary

Rosemary is more than just a flavorful herb—it’s also one of the most versatile mosquito repellent plants for your garden. Its woody scent deters not only mosquitoes but also cabbage moths and carrot flies, making it a helpful addition near vegetable beds.

This aromatic evergreen thrives in hot, dry conditions and does especially well in containers, which is ideal if you need to bring it indoors during colder months. Rosemary can be trimmed into shapes, used as a border, or simply enjoyed for its culinary uses.

When planted near outdoor seating areas or walkways, rosemary adds fragrance, beauty, and natural pest control—all in one plant.

Quick Tips:

• Type: Perennial herb
• USDA Zones: 7–10
• Best Location: Sunny, well-drained pots or beds

6. Basil

Basil isn’t just for pesto—it’s also one of the most practical mosquito repellent plants for gardeners who love both fragrance and function. The strong scent of its leaves acts as a natural deterrent to mosquitoes and even houseflies.

Unlike some herbs, basil doesn’t need to be crushed or processed to be effective. Just having it nearby can help reduce the presence of mosquitoes. All basil varieties work, so feel free to mix different types like sweet basil, Thai basil, or lemon basil for both culinary use and pest control.

Keep basil in well-drained soil and provide plenty of sun and moisture. It grows well in containers, garden beds, or even tucked into flower arrangements.

Quick Tips:

• Type: Annual herb
• USDA Zones: 10–11 (grown as an annual in most zones)
• Bloom Time: Summer to frost
• Best Location: Containers near patios or kitchen gardens

7. Citronella / Scented Geranium

Scented geraniums—especially lemon-scented varieties—are standout mosquito repellent plants that offer beauty and protection in one package. Their strong citrus aroma resembles citronella grass, which is why they’re often called “mosquito plants.”

These geraniums grow quickly and thrive in warm, sunny spots. If you live in a cooler climate, you can still enjoy them in containers and move them indoors before the first frost. Regular pruning keeps them bushy and blooming.

Besides repelling mosquitoes, scented geraniums are a favorite for their delicate, frilly leaves and clusters of pink or purple flowers. They bring color and texture to patios, balconies, and garden edges while helping to keep bugs away.

Quick Tips:

• Type: Annual (in most climates)
• USDA Zones: 10–11
• Bloom Time: Spring through fall
• Best Location: Containers or sunny garden beds

8. Bee Balm (Monarda)

Bee balm, also known as Monarda or horsemint, is a vibrant perennial that does double duty in your garden. Not only is it attractive to pollinators like bees and butterflies, but it’s also one of the most colorful mosquito repellent plants you can grow.

Crushing its leaves releases aromatic oils that mosquitoes dislike, making it a smart choice for planting near patios or outdoor gathering spaces. Its unique, spiky flowers come in bold shades of red, pink, purple, and white, adding a dramatic touch to any bed or border.

Bee balm thrives in sunny locations and moist, well-drained soil. It’s a natural choice for pollinator gardens, and its resistance to pests makes it easy to maintain.

Quick Tips:

• Type: Perennial
• USDA Zones: 4–8
• Bloom Time: Mid to late summer
• Best Location: Mixed flower beds, pollinator gardens, near seating areas

9. Mint

Mint is a fast-growing herb known for its refreshing aroma—and it also ranks among the top mosquito repellent plants. The strong menthol scent confuses mosquitoes, making it harder for them to find you. It’s also effective against flies and even ants.

This perennial is incredibly easy to grow but can spread aggressively if planted directly in the ground. For best results (and to keep it under control), grow mint in containers placed around seating areas, entryways, or kitchen gardens.

In addition to repelling pests, mint is great for culinary use and can be dried for tea or homemade insect repellents.

Quick Tips:

• Type: Perennial herb
• USDA Zones: 3–8
• Best Location: Pots or containers on patios, walkways, or balconies

10. Floss Flower (Ageratum)

Floss flower, also known as Ageratum, is a charming annual that brings a splash of blue, purple, or pink to your garden while quietly working as one of the more underrated mosquito repellent plants.

This low-growing plant contains coumarin, a naturally occurring compound that repels mosquitoes. It’s often used in flower beds, borders, or containers and thrives in full sun to partial shade. While beautiful, floss flower should be handled with care—it’s toxic if ingested by pets or small children.

Because of its soft texture and vibrant blooms, it’s a popular choice for gardeners who want to blend ornamental beauty with natural pest control.

Quick Tips:

• Type: Annual
• USDA Zones: 9–10
• Bloom Time: Planting time to hard frost
• Best Location: Bedding plants, containers, borders

11. Sage

Sage is a fragrant herb with earthy, grounding tones—and it’s also one of the most practical mosquito repellent plants for outdoor living spaces. When burned over a fire pit, sage releases a strong scent that drives mosquitoes away, making it a favorite among campers and backyard grillers alike.

Aside from its use around the fire, sage can be dried and added to homemade insect repellents. It’s also a hardy, low-maintenance perennial that thrives in sunny, well-drained locations. Its soft gray-green leaves and occasional purple blooms add subtle beauty to herb gardens or mixed beds.

Grow sage near patios or outdoor cooking areas for both culinary and mosquito-repelling benefits.

Quick Tips:

• Type: Perennial herb
• USDA Zones: 5–8
• Best Location: Herb gardens, fire pits, sunny borders

12. Allium

Allium, the ornamental cousin of onions and garlic, is not only a stunning addition to flower beds—it’s also one of the more unique mosquito repellent plants. Its tall, globe-shaped flowers emit a strong scent that deters mosquitoes and other pests, while still attracting bees and other pollinators.

Alliums release sulfur compounds through their bulbs and foliage, which mosquitoes find unpleasant. These plants are typically grown from bulbs and bloom in spring or early summer, offering vertical interest and whimsical charm in the garden.

They’re also deer- and rabbit-resistant, making them a low-maintenance and pest-smart choice for both edible and ornamental gardens.

Quick Tips:

• Type: Bulb (includes garlic, chives, onions)
• USDA Zones: 3–8 (varies by variety)
• Bloom Time: Late spring to early summer
• Best Location: Mixed borders, vegetable gardens, ornamental beds
