Sick of mosquitoes buzzing around your backyard gatherings? If you’re searching for a natural way to keep these pests at bay, you’ve probably heard about lemongrass. But does lemongrass really repel mosquitoes? In this post, we’ll explore the science, share practical tips, and show you how to use this fragrant plant to create a mosquito-free oasis.
1. Why Lemongrass? The Science Behind Its Repellent Power
Lemongrass (Cymbopogon citratus) is more than just a culinary herb—it’s a natural mosquito deterrent. Here’s why it works:
- Citronellal Content: Lemongrass contains citronellal, a compound known for its insect-repelling properties. A 2019 study in the Journal of Medical Entomology found that citronellal disrupts mosquito sensory receptors, making lemongrass highly effective.
- Strong Aroma: The citrusy scent of lemongrass overwhelms mosquitoes, deterring them from landing or biting.
- Versatile Use: From garden plants to essential oils, lemongrass offers multiple ways to repel mosquitoes.
Key Fact: Lemongrass is a key ingredient in many commercial citronella candles and sprays, but growing it yourself is a sustainable, cost-effective alternative.
2. Does Lemongrass Repel Mosquitoes?
Yes, lemongrass can effectively repel mosquitoes when used correctly. Here’s what you need to know:
- Strategic Planting: Mosquitoes thrive in shaded, moist areas. Plant lemongrass in sunny spots near patios, decks, or entryways to create a protective barrier.
- Crushed Leaves: Rubbing crushed lemongrass leaves on your skin can provide short-term protection, though essential oil sprays are more potent.
- Complementary Plants: Pair lemongrass with other repellents like lavender or marigolds for enhanced mosquito control.
Pro Tip: Lemongrass thrives in warm climates and well-drained soil. Regular pruning encourages fuller growth and stronger repellent properties.
3. How to Use Lemongrass for Mosquito Control
Ready to make lemongrass your go-to mosquito repellent? Try these practical methods:
- Plant Lemongrass in Your Garden:
- Grow lemongrass in pots or garden beds near outdoor seating areas.
- Space plants 2–3 feet apart to allow for their tall, grassy growth.
- Make a Lemongrass Spray:
- Combine 10–15 drops of lemongrass essential oil with 1 cup of water in a spray bottle.
- Spray on outdoor furniture, skin (test for sensitivity), or around doorways.
- Use Fresh or Dried Lemongrass:
- Place crushed lemongrass stalks in bowls near dining areas.
- Dry lemongrass and hang bundles in gazebos or porches.

4. Caring for Your Lemongrass Plants
To keep your lemongrass healthy and effective, follow these care tips:
- Sunlight: Lemongrass needs 6–8 hours of full sun daily.
- Soil: Use well-draining, fertile soil with a pH of 6.0–7.0.
- Watering: Keep soil consistently moist but not waterlogged.
- Pruning: Trim stalks regularly to promote bushy growth and harvest for culinary or repellent use.
5. Limitations of Lemongrass as a Repellent
While lemongrass is powerful, it has some limitations:
- Range: Its scent repels mosquitoes within a limited radius (about 3–5 feet).
- Potency: Essential oils or sprays are stronger than plants alone.
- Climate: Lemongrass is a tropical plant and may need indoor overwintering in colder climates.
For heavy mosquito infestations, combine lemongrass with other methods like traps or professional pest control.
6. FAQs About Lemongrass and Mosquito Control
