Mosquitoes are not just a nuisance; they are carriers of deadly diseases like malaria, dengue, and Zika virus. While chemical insecticides and repellents are effective at keeping mosquitoes at bay, they often come with health risks and environmental consequences. A natural alternative is to incorporate mosquito-repelling plants into your home. These plants not only add beauty to your indoor spaces but also offer a fragrant and effective way to control mosquitoes without the use of harmful chemicals.
In this article, we’ll explore the best mosquito-killing plants that can be grown indoors, offering a pest-free and eco-friendly solution for your home.
Mosquito-Killing Plants to Grow Indoors
1. Citronella (Cymbopogon nardus)
Citronella is perhaps the most well-known natural mosquito repellent. It’s the source of the essential oil used in many commercial mosquito-repellent products such as sprays, candles, and lotions. The plant’s strong lemon-scented oils are unpleasant to mosquitoes, making them flee.
Benefits of Growing Citronella Indoors:
- Effectiveness: The oils in the plant are highly effective at repelling mosquitoes. If grown in a pot and placed near windows or entry points, it can serve as a natural barrier to mosquitoes.
- Aromatic: Citronella has a fresh citrus aroma, which can also be soothing for the household.
- Care Tips: Citronella requires bright, indirect light and a well-drained potting mix. It should be watered when the top inch of soil is dry.
Best Placement Indoors:
Place your potted citronella plant near windows, doors, or any potential entry points for mosquitoes. You can also crush its leaves to release more of its oils when you’re sitting near it.
2. Lavender (Lavandula angustifolia)
Lavender is a beautiful, fragrant herb known for its calming properties, but it also works as an excellent mosquito repellent. Mosquitoes dislike the strong scent of lavender, especially the essential oils in its leaves and flowers.
Benefits of Growing Lavender Indoors:
- Multi-purpose: Lavender not only repels mosquitoes but can also add a touch of calmness to your home, improving air quality and acting as a sleep aid.
- Aesthetic Appeal: The plant’s purple blooms add a decorative element to any indoor space.
- Care Tips: Lavender thrives in sunny windowsills. It needs at least six hours of direct sunlight each day and well-drained soil. Avoid over-watering, as it prefers a drier environment.
Best Placement Indoors:
Lavender does best in a sunny spot, preferably near a window with direct sunlight. It can be placed on windowsills, countertops, or in living spaces where natural light is abundant.
3. Lemon Balm (Melissa officinalis)
Lemon balm is a member of the mint family with a strong lemon scent that mosquitoes find offensive. The plant’s essential oils are known to be effective at keeping mosquitoes at bay.
Benefits of Growing Lemon Balm Indoors:

Best Placement Indoors
Like citronella, lemon balm can be placed near doors and windows to prevent mosquitoes from entering. Additionally, you can crush its leaves to release a stronger scent when needed.
4. Catnip (Nepeta cataria)
Catnip is not just for felines; it’s also a powerful mosquito repellent. Studies have shown that catnip is more effective at repelling mosquitoes than DEET, the active ingredient in many chemical insect repellents. The plant releases nepetalactone, a compound that drives mosquitoes away.
Benefits of Growing Catnip Indoors:
- Highly Effective: Catnip is one of the most potent natural mosquito repellents available.

You can place catnip in living areas, near windows, or on patios to repel mosquitoes. If you have a cat, just be mindful of where you place it, as they might nibble on the leaves!
5. Basil (Ocimum basilicum)
Basil is a popular culinary herb with a dual purpose: it can be used in the kitchen and is also known to repel mosquitoes. The essential oils in basil, especially the variety “Ocimum gratissimum”, are particularly effective against mosquitoes.
Benefits of Growing Basil Indoors:
- Culinary and Mosquito Repellent: Basil not only enhances your dishes but also keeps mosquitoes away. You get the dual benefit of fresh herbs and a pest-free home.

Place basil in your kitchen, dining area, or near windows. Its fresh, peppery scent will enhance the room while keeping mosquitoes away.
6. Rosemary (Salvia rosmarinus)
Rosemary is another herb with a strong, woody scent that mosquitoes dislike. It also contains cineole, camphor, and other compounds that are effective at repelling insects.

7. Marigolds (Tagetes spp.)
Marigolds are vibrant, cheerful flowers that add a pop of color to any indoor garden. They also contain pyrethrum, a compound used in many commercial insect repellents. The pungent scent of marigolds drives mosquitoes away.
Benefits of Growing Marigolds Indoors:
- Colorful and Functional: Marigolds are beautiful to look at and effective at repelling mosquitoes.

- Proper Lighting: Most mosquito-repelling plants need bright, indirect sunlight to thrive. Ensure they are placed near windows or in well-lit areas of your home.
- Regular Care: Water your plants as needed, ensuring that the soil is well-drained. Overwatering can cause root rot, while under-watering may stunt their growth.
