The 7 Best Plants That Repel Mosquitoes Naturally

1. Lovely Lavender

Oh, lavender has my heart, sweetheart. Not only does it look gorgeous with its purple spikes, but it has a calming scent that helps me drift off to sleep at night. While we find the smell deeply relaxing, mosquitoes find it utterly offensive. They cannot stand the essential oils found in the leaves of this plant. I love planting lavender right along my front walkway. Every time a guest brushes past it, the leaves release a fresh burst of fragrance into the air, keeping the entryway bug-free.

2. Sunny Marigolds

These cheerful little yellow and orange flowers are a staple in my vegetable garden. My father always planted marigolds next to his tomatoes to keep the pests away, and he was absolutely right. Marigolds contain a natural compound called pyrethrum, which is actually used in many commercial insect repellents. They are super easy to grow from seed, honey, and they love the bright sunshine. Plant them in pots and place them on your deck stairs to create a colorful, protective barrier.

3. Fragrant Rosemary

Now, this is a tip my late husband, Richard, loved. Rosemary is a delicious culinary herb, but it is also a powerhouse when it comes to keeping bugs at bay. Rosemary has a very strong, woody scent. When we used to host backyard barbecues, Richard would toss a few fresh sprigs of rosemary right onto the hot coals. The smoke smelled like a gourmet kitchen, and it kept every single mosquito away from the food table. It works like magic!

4. Lemon Eucalyptus

If you want something incredibly powerful, look no further than lemon eucalyptus. The sweet, citrusy scent is wonderfully refreshing on a hot July afternoon. The oil from this plant is so effective that even modern scientists agree with old-fashioned wisdom. In fact, Healthline notes that lemon eucalyptus oil is one of the most trusted natural repellents you can use, even recommended by health authorities. Plant it in a large container on your patio so you can rub a leaf between your palms whenever you go outside.

5. Feisty Catnip

Now, if you have a feline friend at home, they will love you for this one! Catnip contains a natural chemical compound called nepetalactone. Studies have shown that this compound is actually ten times more effective at repelling mosquitoes than some of those harsh store-bought sprays. It grows very easily—sometimes too easily, so I highly recommend planting it in pots so it doesn't take over your entire garden bed, my dear.

6. Sweet Lemon Basil

I love keeping a pot of lemon basil right in the middle of our outdoor dining table. Not only can you pluck a few leaves to toss into a fresh summer salad, but the heavy citrus scent keeps pesky flies and mosquitoes from ruining your dinner. When the breeze blows, the scent drifts across the table, keeping the bugs away while you enjoy your meal.

7. Cool Peppermint

Peppermint is wonderfully refreshing, and the clean, sharp scent is a natural deterrent for all kinds of creepy crawlies, including spiders, ants, and mosquitoes. If you do happen to get a bug bite, you can crush a fresh mint leaf and rub it directly onto the skin for an instant, cooling relief. Just like catnip, mint loves to spread its roots, so keep this one in a pretty container to keep it behaved.

Grandma's Golden Rule for Natural Repellents

Before you head out to the nursery, let me share a little secret with you. Simply having these plants sitting quietly in your garden won't do all the work. The magic happens when the natural oils inside the leaves are released.

Whenever you walk past your plants, gently ruffle the leaves with your hands. If you are sitting on the porch, pluck a leaf of lavender, rosemary, or lemon basil, crush it gently between your fingers, and rub the oils on your wrists and ankles (just do a little patch test first to make sure your skin doesn't get irritated, sweetheart). This releases the active aromas that keep the bugs far, far away.

Frequently Asked Questions

Do plants that repel mosquitoes really work?

Yes, they absolutely do, but you have to help them along! The plants work by releasing strong essential oils that mask the scents (like carbon dioxide and sweat) that attract mosquitoes to humans. For the best results, place them in high-traffic areas where they will be brushed against, or gently crush the leaves to release the oils.

Can I rub these plants directly on my skin?

Many of them, like lavender, lemon balm, and rosemary, can be gently crushed and rubbed on your skin. However, everyone's skin is different. I always tell my grandbabies to test a tiny spot on their inner arm first to make sure they don't get any redness or itching before applying it all over.

Which plant is the strongest natural mosquito repellent?

Lemon eucalyptus and catnip are widely considered some of the most powerful natural repellents. The essential oils derived from them are highly concentrated and offer excellent protection that rivals commercial options.

Are these plants safe for my cats and dogs?

While catnip and rosemary are perfectly safe for pets, some plants like marigolds can cause mild tummy upset if your furry friends chew on them. It is always a good idea to keep your potted plants up on tables or plant stands out of reach of curious puppies and kittens.
