10 Best Mosquito Repellent Plants to Grow in Your Garden
Nothing ruins a relaxing evening on the patio faster than mosquitoes. Whether you're enjoying your morning coffee, hosting a summer barbecue, or simply relaxing after work, mosquitoes can quickly become unwanted guests. While no plant can completely eliminate mosquitoes, certain herbs and flowers contain natural aromatic compounds that mosquitoes tend to avoid, making them excellent additions to patios, decks, porches, balconies, and outdoor entertaining areas.
The key is understanding how to use these plants effectively. Instead of relying on a single herb or flower, creating a diverse collection of fragrant plants around your seating areas can help make your outdoor spaces more enjoyable while also attracting bees, butterflies, hummingbirds, and other beneficial pollinators.
If you're looking to create a beautiful patio garden that works as hard as it looks, these ten plants deserve a place on your list. Many of them are easy to grow from seed, making them an affordable and rewarding way to upgrade your outdoor space this season.
Before we dive into the list, be sure to read our complete guides on mosquito-conscious gardening: Mosquito Repellent Plants: The Complete Guide and Do Mosquito Repellent Plants Really Work?
Why Certain Plants Help Deter Mosquitoes
Mosquitoes locate people primarily by sensing carbon dioxide, body heat, moisture, and skin odors. Highly fragrant herbs release natural aromatic oils into the air that can interfere with a mosquito's ability to zero in on its target. While the fragrance alone won't eliminate mosquitoes entirely, surrounding your seating areas with these plants creates a more pleasant environment and forms one layer of a complete mosquito-management strategy.
The best results come from combining fragrant plants with good airflow, removal of standing water, proper garden maintenance, and pollinator-friendly landscaping. Think of these plants as your first line of defense — beautiful, functional, and completely natural.
What to Look for in a Mosquito-Repelling Garden Plant
The best mosquito-conscious patio plants should also provide beauty and practical value. Look for plants that offer long bloom periods, pleasant fragrance, attractive foliage, pollinator benefits, easy container growth, heat tolerance, and low maintenance. Fortunately, many herbs and flowering annuals meet all of these requirements — and most can be started easily from seed.
1. Lavender
Lavender is one of the most beloved garden plants — and one of the most effective mosquito deterrents. Its strong floral scent, which humans find deeply pleasant, is overwhelming to mosquitoes. The linalool and linalyl acetate compounds in lavender oil are the key — they disrupt the mosquito's sensory system and make it difficult for them to locate a host.
Plant lavender in sunny borders, near patios, or in containers by doorways for best results. It thrives in well-drained soil and full sun, making it a low-maintenance powerhouse that blooms reliably year after year. Lavender also attracts bees and butterflies, making your garden healthier while adding stunning color throughout the growing season.
Grow it from seed and enjoy blooms that repel pests while attracting pollinators. Try our Vicenza Blue English Lavender Seeds or the stunning Bandera Deep Purple Spanish Lavender Seeds — and browse our full lavender collection for more varieties.
2. Rosemary
Rosemary's woody, piney scent is a natural mosquito deterrent that has been used in gardens for centuries. The aromatic oils in rosemary — particularly camphor and 1,8-cineole — are known to repel a wide range of insects. It thrives in hot, dry conditions and works beautifully in herb gardens, raised beds, or as a low hedge around seating areas.
One of rosemary's best features is its versatility. It works equally well as a culinary herb, a landscape plant, and a container specimen. Burning a few sprigs of rosemary on a backyard fire also releases repellent smoke — a great trick for summer evening gatherings. Its evergreen foliage provides year-round interest in many climates, and it's exceptionally drought tolerant once established.
Start from seed with our Rosemary Herb Seeds and enjoy a perennial plant that repels pests, supports pollinators, and looks beautiful year after year.
3. Marigolds
Marigolds contain pyrethrum, a compound used in many commercial insect repellents, as well as limonene and other volatile oils that mosquitoes find offensive. Their bold orange and yellow blooms are a classic garden staple that doubles as a natural pest barrier — and they're one of the easiest flowers to grow from seed.
Plant marigolds along garden borders, near vegetable beds, or in pots on your deck. They're fast-growing and bloom all summer long with minimal care. Compact varieties work especially well in decorative pots surrounding seating areas, where their cheerful color and pest-deterring fragrance can do double duty.
Our African Marigold Antigua Primrose Seeds and African Marigold Antigua Mix Seeds are excellent choices for a colorful, pest-deterring display. For a more compact option perfect for containers, try our Marigold Chica Yellow Seeds.
4. Basil
Basil is a double-duty plant — it's a culinary staple and a potent mosquito repellent. The strong volatile oils in basil leaves, particularly estragole and linalool, are toxic to mosquito larvae and repel adult mosquitoes on contact. Keep pots of basil near outdoor seating areas, on kitchen windowsills, or beside the grill for maximum effect.
Basil pairs exceptionally well with rosemary and lavender when creating attractive patio displays. It grows quickly from seed, produces lush green foliage all season, and performs beautifully in containers. Imagine harvesting fresh basil while grilling outdoors — a practical and beautiful addition to any outdoor space.
Our Everleaf Genovese Basil Seeds are a top pick for both cooking and pest control, while Siam Queen Spicy Basil Seeds offer an ornamental twist with an especially powerful scent.
5. Lemon Balm
Lemon balm (Melissa officinalis) is a member of the mint family with a refreshing citrus-mint fragrance that mosquitoes strongly dislike. Studies have shown that lemon balm contains high concentrations of citronellal — the same compound found in citronella — making it one of the most scientifically supported natural mosquito deterrents you can grow.
It's incredibly easy to grow, thrives in partial to full sun, and performs exceptionally well in containers where its spreading habit can be controlled. Crush a few leaves and rub them on your skin for a natural, short-term repellent effect. Its attractive green foliage and pollinator-friendly flowers make it a beautiful addition to any patio garden.
Lemon balm grows vigorously from seed and can be harvested throughout the season. Plant it in containers near seating areas, along deck railings, or beside porch steps for best results.
Why Containers Work So Well
One of the biggest advantages of growing mosquito-repelling plants in containers is flexibility. You can place fragrant plants exactly where people spend the most time — around patio furniture, near outdoor dining tables, along deck railings, beside porch steps, near fire pits, around hot tubs, and along walkways. Rather than planting herbs far away in the landscape, containers bring fragrance directly into your outdoor living area where it matters most.
Containers also let you move plants indoors when frost threatens, extend the season, and experiment with different combinations until you find what works best for your space.
6. Mint (Peppermint)
Mosquitoes hate the strong menthol scent of peppermint. The menthol and menthone compounds in mint are powerful natural insect deterrents — research has shown that peppermint oil can repel mosquitoes for up to 2.5 hours when applied to skin. As a garden plant, mint releases its scent continuously, especially when leaves are brushed or crushed.
Because mint spreads aggressively through underground runners, most gardeners recommend growing it in pots rather than directly in garden beds. This actually makes it perfect for patio use — place containers of mint near seating areas, on decks, beside outdoor dining tables, and along walkways. It's fast-growing, low-maintenance, and also attracts beneficial pollinators when allowed to flower.
Peppermint is one of the most versatile herbs you can grow — use it fresh in drinks and cooking, dry it for tea, or simply enjoy its pest-deterring fragrance all season long.
7. Catnip (Catmint)
Research has shown that catnip (Nepeta cataria) can be up to 10 times more effective than DEET at repelling mosquitoes in laboratory settings. The active compound, nepetalactone, is a powerful natural deterrent that interferes with the mosquito's ability to detect carbon dioxide — the primary way mosquitoes find their hosts. It's also incredibly easy to grow and spreads readily in the garden.
Plant catnip along pathways or near seating areas — just be prepared for neighborhood cats to pay a visit! It produces attractive gray-green foliage and small lavender flowers that pollinators love. As a perennial, it comes back reliably each year with minimal care, making it an excellent long-term investment for your mosquito-repelling garden.
Our Catnip / Catmint Perennial Herb Seeds are a must-have for any mosquito-repelling garden.
8. Citronella Grass
Citronella grass (Cymbopogon nardus) is perhaps the most recognized mosquito-repelling plant in the world — it's the source of the oil used in citronella candles, torches, and sprays. The plant itself releases its distinctive citrus-grass scent when leaves are crushed or brushed, and it provides dramatic tropical foliage that looks beautiful in large decorative containers around patios and outdoor living spaces.
Citronella grass grows as a tall, clumping grass and works best in large containers or as a landscape accent in warm climates (USDA zones 10–12). In cooler climates, grow it as an annual or bring it indoors for winter. It performs best in full sun, warm temperatures, and well-drained soil. While it won't eliminate mosquitoes on its own, it's a powerful addition to a multi-plant mosquito-deterring strategy.
9. Scented Geraniums
Scented geraniums — particularly lemon-scented varieties (Pelargonium citrosum) — contain citronellol and geraniol, the same compounds found in citronella oil. These natural compounds are proven mosquito deterrents, and the plants release them continuously through their aromatic foliage. They're beautiful in containers and hanging baskets, and their fragrant leaves can be rubbed on skin as a mild, short-term repellent.
Unlike traditional bedding geraniums, scented geraniums are grown primarily for their wonderfully aromatic foliage, which can smell like lemon, rose, mint, citrus, or spice depending on the variety. They thrive in full sun with moderate watering, tolerate warm summer weather exceptionally well, and make excellent patio plants throughout the summer months. They become conversation pieces on patios while adding texture and fragrance to mixed container gardens.
10. Bee Balm (Monarda)
Bee balm is a native perennial with showy red, pink, or purple flowers that attract pollinators while its strong, oregano-like scent deters mosquitoes. The aromatic oils in bee balm — particularly thymol and carvacrol — are the same compounds found in thyme and oregano that are known to repel insects. Crushing the leaves releases these oils in concentrated form.
It's a beautiful addition to any cottage or wildlife garden, and it spreads over time, coming back reliably each year as a perennial. Plant it behind shorter herbs and flowers around patios and backyard seating areas for a tall, colorful, fragrant backdrop that works hard all season long.
Build a Layered Mosquito-Repelling Patio Garden
Rather than planting one type of herb, combine several species into attractive container displays for layered protection and visual impact. Professional landscape designers recommend layering different plant heights for the best effect:
Tall Background: Rosemary, Lavender, Citronella Grass
Medium Height: Basil, Lemon Balm, Catnip
Front Edge: Marigolds, Mint
Example container combinations that work beautifully together:
- Container One: Lavender + Marigolds
- Container Two: Rosemary + Basil
- Container Three: Lemon Balm + Mint
This creates different heights, textures, fragrances, and bloom colors while producing an eye-catching patio display that works as a natural mosquito barrier.
Other Ways to Naturally Reduce Mosquitoes
Plants work best when combined with smart gardening practices. Here are the most impactful steps you can take alongside your mosquito-repelling garden:
Remove Standing Water: Mosquitoes require standing water to complete their life cycle. Check regularly for buckets, bird baths, plant saucers, children's toys, wheelbarrows, and clogged gutters. Even a bottle cap of water is enough for mosquitoes to breed.
Increase Air Movement: Mosquitoes are weak fliers. Adding outdoor fans, proper plant spacing, and open landscape design can make patios significantly more comfortable during peak mosquito hours.
Keep Landscaping Maintained: Healthy lawns, weed-free beds, trimmed shrubs, clean gutters, and removed leaf litter all reduce the hiding places and resting spots that mosquitoes prefer.
Tips for Maximum Mosquito Repellent Effect
- Crush or brush leaves regularly to release the repellent oils — most plants only emit their scent actively when disturbed.
- Plant in clusters rather than single specimens for a stronger scent barrier.
- Place plants strategically near seating areas, doorways, and windows where mosquitoes are most likely to enter.
- Combine multiple plants for layered protection — no single plant will eliminate mosquitoes entirely.
- Eliminate standing water nearby, as this is where mosquitoes breed regardless of what plants you grow.
