Lemongrass is not only an effective way to repel mosquitoes, but it’s also a really pretty ornamental and hardy plant to add to your yard. If you’re looking for the best way to naturally deter mosquitoes, ticks, and other pests, keep reading!

What is Lemongrass? 

Lemongrass is a tall perennial grass that belongs to the grass family. It’s native to tropical and subtropical regions in Asia and Africa. That means it needs a hot climate to live in. For those who have cold winters, it’s best to plant these in a pot so they can be taken indoors during the winter unless you want to replant them annually. 

Lemongrass has long, slender stems that are topped with light green, lemon-scented leaves. The plant is often used as a culinary herb and is also known for its medicinal properties that can be used to treat a variety of ailments. It’s an effective repellent for mosquitoes because they are deterred by some strong scents like the one that comes from this plant. Lemongrass offers a pleasing scent for people, but it’s an off-putting pungent aroma to mosquitos and other pesky insects like fruit flies and ticks. 

The Science Behind Lemongrass and Mosquitoes 

The essential oil of lemongrass, which is citronella oil, has been used for centuries as an effective mosquito repellent. The active ingredient in the citronella is citronellal, which is what gives the oil its lemony scent and repellent properties. When you apply citronella oil to the skin, citronellal acts as a natural repellent that confuses the olfactory receptors of the mosquito. This makes it difficult for biting insects to locate their target. Some studies have also found that this simple repellent has insecticidal properties, which means it can help to kill any mosquitoes that come into contact with it and be a natural alternative to bug sprays and bug traps.

How to Use Lemongrass to Repel Mosquitoes 

There are a few different ways to use lemongrass mosquito repellent in a natural way to keep mosquitoes away. The most popular option is to purchase a citronella candle or oil diffuser and place it in the area you want to protect from mosquitoes. This tends to be a lot easier than planting a lemongrass plant and caring for it. You can also purchase or make your own citronella spray bottle, lotion, or lemon balm. 

You can also purchase a blend of essential oils that are mixed with other natural plant-based repellents. If you mix your own oils, be sure to use a carrier oil like coconut or jojoba oil because essential oils are very concentrated. Some people with sensitive skin might find they have skin irritation from applying these oils and could benefit more from planting some beautiful tall lemongrass plants. Apply small amounts of oils to a small area of your skin before you apply them to your entire body to make sure you won’t have any adverse reactions.

If you grow lemon grass plants in your yard or in pots, you’ll need to strategically place them near the areas of your outdoor spaces where you spend the most time. Planting a lot of lemongrass around your yard and also placing them in your seating area can offer more layers of repellent and a more wide-spreading heavenly citronella scent. Remember that this plant requires a warm climate and direct sunlight, so make sure to place it in an area that will receive full sun and plenty of water and allow for good drainage. 

In Summary: Do Lemongrass Plants Repel Mosquitoes? 

Lemongrass is a great way to naturally repel mosquitoes from your outdoor area. The essential oil of lemongrass, citronella, contains citronellal, which is an effective mosquito repellent and even a great insecticide. Growing lemongrass plants in your yard is easy, especially if you have an ideal climate for the plant. If your climate isn’t great for lemongrass, you can use alternatives like citronella oil as repellents. With these options, you can enjoy the outdoors without having to worry about pesky mosquitoes!
