7 Best Mosquito-Repellent Plants for Your Garden

You don’t have to reach for the heavy-duty chemical sprays to keep the bugs at bay—nature has its own built-in security system! By choosing the right greenery, you can give mosquitoes a natural “eviction notice” from your backyard.

++Garlic (Allium sativum)
Garlic
In the movies, garlic is famous for keeping vampires away. In real life, it’s just as effective against mosquitoes! These little biters can’t stand the pungent aroma of garlic and will go out of their way to avoid it. It’s definitely worth planting some in your herb garden. The best part? The scent comes from both the harvested bulbs and the green stalks as they grow.

++Rosemary (Salvia rosmarinus)
Rosemary
Rosemary is another fantastic ally in the fight against mosquitoes. This hardy, evergreen shrub is a survivor—it handles drought and cold like a champ and can even be grown as a low hedge. You’ll notice that wonderful, woodsy scent the moment you brush your hand against the needles. While we find the aroma relaxing and much more pleasant than garlic, mosquitoes find it totally repulsive and will steer clear.

++Lemongrass (Cymbopogon citratus)
Lemongrass
Lemongrass is a favorite for many gardeners, and for good reason! You can use the leaves for a refreshing tea, add it to desserts, or use it as a healing herb. Just like rosemary, it’s packed with essential oils that act as a natural bug repellent. It’s a beautiful, functional plant to have on hand if you want to keep your patio mosquito-free.

++Lemon Balm (Melissa officinalis)
Lemon Balm
Lemon balm is another citrusy superstar loaded with essential oils. Its bright, lemony scent fills the air in your garden or on your balcony, making it a “no-fly zone” for mosquitoes. When planted in the right spot, it grows into a lovely, bushy shape. Pro tip: grow it in pots! That way, you can move your lemon balm “shield” to wherever you happen to be sitting.

++Tomatoes (Solanum lycopersicum)

It’s not just herbs that do the heavy lifting; some of our favorite veggies are great at repelling pests, too. Tomatoes are the MVP here. Interestingly, the tomato plant itself usually has a much stronger, earthier scent than the actual fruit. Insects aren’t fans of that distinct “tomato leaf” smell. If you plant some cherry tomatoes on your balcony or put a tomato bed right next to your seating area, you’ll likely notice a lot fewer uninvited guests.

++Basil (Ocimum basilicum)
Basil
Basil is another great natural repellent. While those lush green leaves are delicious in the kitchen, the plant can be a bit picky about its living conditions. It needs plenty of sunlight and just the right amount of water. Be careful to avoid soggy soil, though—if the roots get waterlogged, the leaves will dry out, the scent will fade, and its mosquito-fighting powers will disappear.

++Lavender (Lavandula angustifolia)
Lavender
Lavender is arguably the most popular plant for keeping mosquitoes away, and it’s not just because of those gorgeous purple blooms. It has a very strong, herbal scent and is so rich in essential oils that it’s incredibly effective at deterring mosquitoes and gnats. The best part? While it keeps the “bad” bugs away, it’s a favorite snack for beneficial pollinators like bumblebees. It’s a win-win for your garden!

%%Walnut (Juglans regia)
Walnut
Here’s a real “insider secret”: the walnut tree. Centuries ago, people used to plant these right next to manure piles to keep flies and mosquitoes from swarming. Once again, it’s those powerful essential oils doing the work. Not only does this beautiful tree help keep the bugs away, but it also rewards you with a delicious harvest of nuts every fall!
