Citronella Grass (Cymbopogon nardus)
Best OverallPros
- Strongest natural repellent scent
- Grows quickly into a large clump
- Can be crushed for direct application
Cons
- Not frost-tolerant
- Requires full sun to thrive
Citronella Grass is the plant most commonly associated with mosquito repellent, and for good reason. Its leaves contain high levels of citronellal, the compound that masks carbon dioxide and lactic acid scents that attract mosquitoes. Owner reviews consistently note that placing pots of citronella grass near seating areas reduces mosquito presence significantly.
This grass can reach 5-6 feet tall in a single season, making it an effective barrier plant. It grows best in warm climates (USDA zones 10-12) but can be overwintered indoors in cooler regions. For maximum effect, crush a few leaves to release the oils, as the plant's scent is mild when undisturbed.
Lemon Balm (Melissa officinalis)
Best for ShadePros
- Thrives in partial shade
- Very easy to propagate
- Strong lemon scent when touched
Cons
- Can become invasive
- Leaves wilt in intense heat
Lemon Balm is a member of the mint family and shares its vigorous growth habit. It contains citronellal and geranial, both of which are effective mosquito repellents. Many owners report that brushing against the leaves releases a strong lemon aroma that keeps mosquitoes at bay, and the plant is easy to grow even for beginners.
One of its best features is its tolerance for partial shade, making it a good choice for covered patios or north-facing gardens. However, it spreads aggressively via runners, so container planting is recommended to keep it contained. Regular pruning encourages bushier growth and more fragrant leaves.
Lavender (Lavandula angustifolia)
Best DecorativePros
- Beautiful purple flowers
- Drought-tolerant
- Attracts pollinators
Cons
- Requires well-drained soil
- Repellent effect is mild
Lavender is prized for its calming fragrance and ornamental value. Its essential oils contain linalool and camphor, which have been shown to repel mosquitoes. While the effect is not as strong as citronella grass, many owners appreciate that lavender adds beauty to the garden while providing a modest level of protection.
Lavender thrives in full sun and well-drained soil, making it ideal for rock gardens or border plantings. It is also drought-tolerant once established, requiring minimal watering. For best results, plant lavender near seating areas where its scent can be enjoyed, and crush the flowers to release more oils.
Marigolds (Tagetes spp.)
Best for ContainersPros
- Contains natural insecticide
- Vibrant, long-lasting blooms
- Grows well in pots
Cons
- Annual in most climates
- Scent is not pleasant to all
Marigolds contain pyrethrum, a natural compound used in many commercial insect repellents. The strong, pungent scent of marigolds is known to deter mosquitoes, as well as other garden pests like aphids. Owners often place potted marigolds on patios or near doorways for a colorful barrier.
These annuals are easy to grow from seed and bloom continuously from spring until frost. They prefer full sun and moderate watering. While the repellent effect is most noticeable when the plants are crushed, their presence alone can reduce mosquito activity in small areas. Deadheading spent flowers encourages more blooms.
Catnip (Nepeta cataria)
Best PotencyPros
- 10x more effective than DEET in studies
- Very hardy and easy to grow
- Drought-tolerant
Cons
- Attracts cats
- Can spread aggressively
Catnip contains nepetalactone, a compound that studies have shown to be more effective at repelling mosquitoes than DEET in some laboratory conditions. The plant is a hardy perennial that thrives in poor soil and requires little care. Owners report that crushing the leaves releases a strong scent that mosquitoes avoid.
One major caveat is that catnip attracts cats, which may roll in or damage the plant. It also spreads readily via seeds and runners, so it can become invasive if not controlled. For best results, plant catnip in a contained area away from high-traffic zones, and use the leaves to make a homemade repellent spray.
What to check before buying mosquito-repelling plants
Before purchasing plants, consider your local climate and growing conditions. Check the USDA hardiness zone to ensure the plant will survive winter in your area. Also assess the amount of sunlight your planting location receives, as most repellent plants require at least 6 hours of direct sun daily.
Think about the plant's growth habit. Some plants like lemon balm and catnip spread aggressively and may overtake a garden bed. Container planting is a good solution for these species. Finally, consider the plant's maintenance needs, including watering frequency and pruning requirements.
Mistakes to avoid
Do not assume that simply having the plant in your garden will create a mosquito-free zone. The repellent effect is strongest when leaves are crushed or brushed against, releasing the essential oils. Placing plants in a corner where no one touches them limits their effectiveness.
Avoid planting only one type of repellent plant. A diverse mix of plants creates a more effective barrier. Also, do not rely solely on plants for mosquito control in areas with high mosquito populations. Combine them with other methods like removing standing water and using fans.
