Different Types of Plants That Repel Mosquitoes
Citronella (Cymbopogon nardus)
Known as the “mosquito plant,” citronella grass emits a strong citrus scent that repels mosquitoes. Its natural oils are commonly extracted and used in insect repellent products, but the live plant itself can also help deter mosquitoes when placed in outdoor spaces.
Often used in candles and sprays, citronella is a popular choice for mosquito control. However, keeping the actual plant in gardens, patios, or near seating areas can provide ongoing protection. Its effectiveness increases when leaves are crushed, releasing more of its natural oils.
Citronella grass grows best in USDA zones 10-12, thriving in warm, humid climates with plenty of sunlight. It requires well-draining soil and regular watering but is relatively low-maintenance. In cooler regions, it can be grown in containers and moved indoors during winter.
Lavender (Lavandula spp.)
The pleasant floral scent of lavender is a natural mosquito repellent. It contains linalool, a compound known to disrupt mosquito senses and reduce their ability to detect potential hosts. Additionally, lavender attracts beneficial pollinators such as bees and butterflies while keeping pests away.
This versatile plant is often used in sachets, oils, and dried bouquets for its calming aroma. When planted in gardens or near entryways, lavender provides a fragrant barrier against mosquitoes. Crushing the leaves or flowers releases more of its essential oils, increasing its effectiveness.
Lavender thrives in USDA zones 5-9 and prefers well-draining, sandy soil with full sun exposure. It is drought-tolerant once established and requires minimal maintenance, making it an excellent addition to both ornamental and functional landscapes.
