Mosquitoes are not only annoying pests, but they can also transmit dangerous diseases such as malaria, dengue fever, and Zika virus. Many people resort to using chemical-based mosquito repellents to keep these pesky insects at bay. However, there is a natural and eco-friendly alternative – mosquito-repellent plants. In this glossary, we will explore what mosquito-repellent plants are, how they work, and some popular examples.

What are Mosquito-Repellent Plants?

Mosquito-repellent plants are a group of plants that naturally repel mosquitoes. These plants contain certain compounds and oils that mosquitoes find unappealing, deterring them from landing on or biting humans. By incorporating these plants into your garden or indoor space, you can reduce the presence of mosquitoes and decrease the risk of mosquito-borne diseases.

How Do Mosquito-Repellent Plants Work?

Mosquito-repellent plants work by emitting strong scents or producing compounds that mosquitoes dislike. These scents can mask the human scent, making it difficult for mosquitoes to locate their prey. Additionally, some plants release oils that act as natural insecticides, repelling mosquitoes and other insects. The combination of these scents and compounds creates a hostile environment for mosquitoes, keeping them away from the area.

Popular Mosquito-Repellent Plants

There are several popular mosquito-repellent plants that you can consider adding to your garden or indoor space. These plants not only repel mosquitoes but also add beauty and fragrance to your surroundings. Some of the most commonly used mosquito-repellent plants include:


Citronella is perhaps the most well-known mosquito-repellent plant. It is a perennial grass that emits a strong lemony scent, which masks the human scent and repels mosquitoes. Citronella plants can be grown in pots or planted directly in the ground, making them a versatile choice for any space.

Lemon Balm

Lemon balm, also known as Melissa officinalis, is a herb that belongs to the mint family. It has a pleasant lemony fragrance that mosquitoes dislike. Lemon balm can be grown in gardens or containers, and its leaves can be crushed and rubbed on the skin for added protection against mosquito bites.


Lavender is a popular plant known for its beautiful purple flowers and calming scent. While humans find the scent of lavender soothing, mosquitoes find it repulsive. Planting lavender in your garden or placing dried lavender sachets indoors can help keep mosquitoes away.


Marigold plants not only add vibrant colors to your garden but also repel mosquitoes. The strong scent of marigolds masks the human scent and acts as a natural mosquito deterrent. Planting marigolds around your outdoor seating areas or near windows can help keep mosquitoes at bay.


Catnip, also known as Nepeta cataria, is a herb that is known to attract cats. However, it also repels mosquitoes. The active compound in catnip, nepetalactone, is highly effective in deterring mosquitoes. Planting catnip in your garden can help create a mosquito-free zone.


In conclusion, mosquito-repellent plants offer a natural and eco-friendly solution to keep mosquitoes away. By incorporating these plants into your garden or indoor space, you can enjoy the benefits of mosquito control without the use of chemical-based repellents. Consider adding citronella, lemon balm, lavender, marigold, and catnip to your collection of mosquito-repellent plants and create a mosquito-free environment.
