Top 10 Plants That Repel Mosquitoes and Gnats Naturally [Video Tutorial]
1. Lavender – Fragrant and Fierce
Why It Works:
Lavender’s essential oils emit a scent mosquitoes can’t stand. Bonus: it’s calming for humans and attracts pollinators like bees and butterflies.
Planting Tips:
- Needs full sun
- Prefers well-drained, sandy soil
- Space 12–18 inches apart
- Water moderately; let it dry between soakings
Pro Tip: Avoid planting in clay-heavy soil — it holds too much moisture and causes root rot.
2. Lemon Balm – The Refreshing Repeller
Why It Works:
This member of the mint family contains citronellal, a natural mosquito deterrent. Rub fresh leaves on your skin for a DIY repellent.
Planting Tips:
- Thrives in part sun to full sun
- Likes moist but well-draining soil
- Great for containers (it spreads aggressively)
Pro Tip: Keep it pruned to avoid unwanted takeover and prevent bitterness in leaves.
3. Citronella Grass – The OG Bug Bouncer
Why It Works:
Unlike synthetic citronella candles, this plant contains the real deal: citronella oil. It releases a strong scent that masks attractants for mosquitoes.
Planting Tips:
- Needs full sun and warmth
- Can grow 2–4 feet tall
- Pot it in colder regions and bring indoors in winter
Watch Out: Don’t confuse with citronella-scented geraniums — they’re not as effective.
4. Basil – Tasty and Tactical
Why It Works:
Basil’s essential oils serve as a natural insect repellent, and the plant’s aroma can interfere with mosquito scent tracking.
Planting Tips:
- Full sun and rich, moist soil
- Water regularly
- Pinch off flower buds to keep leaves flavorful and potent
Bonus: Protects tomato plants when planted nearby.
5. Mint – Cool Smell, Strong Defense
Why It Works:
The menthol in mint leaves acts as a natural mosquito deterrent. It’s a win for cocktails and pest control.
Planting Tips:
- Grows in full sun to partial shade
- Prefers moist, well-drained soil
- Always plant in containers unless you want a garden takeover
Important: Harvest frequently to prevent leggy growth and bitterness.
6. Marigolds – Bright, Bold, and Bug-Blocking
Why It Works:
Marigolds release pyrethrum, a compound used in many insect repellents. Their strong scent deters mosquitoes, aphids, and even whiteflies.
Planting Tips:
- Needs full sun
- Deadhead blooms for continuous flowering
- Ideal for borders and entry points
Fun Fact: Great companion plant for vegetables and herbs.
7. Rosemary – Herb with a Hidden Superpower
Why It Works:
The woody, pine-like scent of rosemary masks human smells and confuses mosquitoes. Plus, it’s excellent for grilling.
Planting Tips:
- Loves hot, sunny spots
- Requires sandy, well-drained soil
- Minimal watering once established
Tip: Burn dried rosemary as a natural incense to keep bugs away during evening gatherings.
8. Catnip – Not Just for Cats
Why It Works:
Catnip contains nepetalactone, which is 10x more effective than DEET at repelling mosquitoes (according to some studies).
Planting Tips:
- Full sun to partial shade
- Moderate watering
- May attract neighborhood cats, so plan accordingly
Warning: Invasive in some regions. Keep it contained.
9. Scented Geraniums (Lemon-Scented)
Why It Works:
While not true citronella, lemon-scented geraniums offer a powerful fragrance that confuses and repels bugs.
Planting Tips:
- Full sun, well-drained soil
- Perfect for pots and patio decor
- Pinch back for bushier growth
Tip: Crush leaves and rub on skin for light protection (but test for irritation first).
10. Eucalyptus – Tall, Elegant, and Effective
Why It Works:
Eucalyptus oil is a powerful mosquito repellent. Growing the plant provides ongoing protection — and a beautiful aesthetic.
Planting Tips:
- Needs lots of sun and warmth
- Choose dwarf varieties for containers
- Prune to manage height and encourage oil-rich growth
Note: Best suited for warm climates or overwintering indoors.
General Tips to Boost Mosquito Repellent Power in Your Yard
Even the best anti-mosquito plants won’t help much if you’re unknowingly setting the scene for a bug infestation. Here’s how to maximize your plant power:
Eliminate Standing Water
Dump water from flowerpot saucers, buckets, kiddie pools, gutters, and birdbaths.
Mosquitoes can breed in as little as a bottle cap of water.
Light It Right
Swap bright white lights for yellow LED “bug lights” — they attract fewer pests.
Create Airflow
Use oscillating fans on patios. Mosquitoes are weak fliers.
Layer with DIY Repellents
Crush fresh mint, basil, or lemon balm and rub on your arms and legs.
Burn rosemary or sage bundles during outdoor meals.
Cluster Your Plants
Don’t plant just one basil and hope for the best.
Use clusters of 3–5 plants around patios, doors, and sitting areas.
Indoor Plants That Repel Mosquitoes
Yes, you can repel bugs and upgrade your indoor air quality.
Top indoor-friendly mosquito-repelling plants:
- Lavender (bright window)
- Lemon balm
- Mint (kitchen herb garden)
- Rosemary (sunny windowsill)
- Scented geraniums
Pro Tip: Place near windows, doors, and common entry points.
Common Mistakes to Avoid
- Relying on one plant alone
- Letting water collect in containers
- Planting sun-loving herbs in the shade
- Forgetting to harvest herbs (which reduces oil potency)
- Ignoring soil drainage needs

FAQ
What plant is most effective at repelling mosquitoes?
Citronella grass is widely considered the most effective mosquito-repelling plant due to its high levels of citronellal — the same compound used in many commercial insect repellents. Lavender, catnip, and lemon balm are also highly effective.
Do mosquito-repelling plants really work?
Yes, many plants release essential oils and compounds that naturally repel mosquitoes. While they may not eliminate every insect, strategically placing these plants in clusters around patios, doors, and windows can significantly reduce mosquito activity.
What plants repel both mosquitoes and flies?
Plants like mint, basil, lavender, and marigolds repel mosquitoes and common flies. Their strong scents mask human odors and deter multiple types of insects.
Can I grow mosquito-repellent plants indoors?
Yes! Mint, rosemary, lavender, lemon balm, and scented geraniums grow well indoors if given enough sunlight. Place them near windows or entryways to maximize their bug-repelling benefits.
How many mosquito-repelling plants do I need?
It depends on your space, but one or two plants won’t be enough. For effective protection, plant in groups of 3–5 near sitting areas, doorways, and high-traffic zones. Layer multiple plant types for best results.
What’s the difference between citronella grass and citronella geraniums?
Citronella grass is the true source of citronella oil, while citronella-scented geraniums (also called mosquito plants) mimic the scent but offer less repellent power. For real results, choose citronella grass.
Do these plants repel gnats too?
Yes, many of these plants — including lavender, mint, basil, and rosemary — help deter gnats and other flying pests thanks to their strong aromatic compounds.
Can I use these plants for DIY mosquito repellent?
Absolutely. You can crush leaves from plants like mint, lemon balm, basil, and lavender and rub them directly on your skin (always test a small area first). You can also steep them in oil or alcohol to make DIY sprays.
Will these plants attract bees or other insects?
Some, like lavender and marigolds, attract pollinators like bees and butterflies — which is great for your garden. However, they repel biting insects like mosquitoes, flies, and gnats.
What are the best container plants to repel mosquitoes on a balcony or patio?
Great options for containers include basil, mint, rosemary, lemon balm, and marigolds. These plants thrive in pots and provide excellent pest protection in small spaces.
