Table of Contents

    There’s one thing about summer that everyone can agree is the ultimate worst: mosquitos. Year after year, they return to make every nice summer evening and camping trip an itchy mess. Thankfully, increasingly effective solutions like citronella sprays and candles, heavy-duty bug sprays, and mosquito dunks are all over the market—and do a good job of reducing how many bugs you deal with when you head outside during the summer.

    However, if you want to increase your natural pest-fighting game in your own backyard, and avoid needing quite as much bug spray, you can also take to your garden and add a few plants that are known to drive mosquitos away.

    While they’ll never be 100% effective, living plants can have some properties that keep nature’s bloodsuckers at bay, and if you have a knack for gardening, you may want to plant some of these lovely plants regardless.

    Here are our top recommendations for plants you can add to your personal garden or patio pots to make mosquitos think twice before crashing your patio party.

    Fun Fact

    One plant you will not find on this list is the citronella plant, Pelargonium x citrosum, which was debunked as a mosquito buster by a Florida A&M study.

    Do Mosquito-Repelling Plants Actually Work?

    Biting insects that feed on blood (such as ticks and mosquitoes) locate their targets by sensing the odors and gases given off by warm-blooded creatures. Sweat and the carbon dioxide given off by breathing are key attractors. Garden plants that have strong scents can help to camouflage the scents that these insects use to target their victims, thereby confusing the bugs and protecting us from bites.

    But it’s rarely enough to simply fill your landscape with growing plants of these types and hope that mosquitoes will vanish. In most cases, you’ll need a more concentrated form of the plant’s scent, which can be obtained by burning or crushing the leaves to release the essential oils that produce the odor.

      Already a favorite of many for its gorgeous fragrance and versatility in cooking, baking, and mixology (not to mention being a favorite of pollinators), lavender scores another win for repelling mosquitos. The oil naturally created by the lavender plant is thought to potentially even inhibit mosquitos’ sense of smell. While the distilled essential oil applied to your skin is even more effective, a lavender bush in your garden won’t hurt your pest-fighting case at all.

      Mint

      Another plant with near unlimited uses, mint comes in a wide range of varieties to suit your preferences—and any of them will be a deterrent to mosquitos. Mint is near-impossible to kill, incredibly low maintenance, and just as good for adding to your cocktails as it is for keeping your patio pest-free.

      Add one to your outdoor sitting area—or start a collection of mint varieties. But be warned, if you plant them in the ground, they’ll spread like wildfire, so pot planting is usually best.

      Rosemary

      Popular among many gardeners, this woody, fragrant herb adds an amazing touch to countless recipes and can grow massively in outdoor gardens. Its scent is a deterrent to mosquitos as well as other pesky bugs, like cabbage moths.

      Rosemary loves warm and dry climates, and may need to be moved indoors in areas with harsh, cold winters. But, all summer long it can adorn your patio and keep pests at bay. Rosemary does need full sun to prevent needle drop, but it prefers to dry out between waterings.

      It might surprise you to know that this perennial plant, famous for attracting pollinating insects such as bees and butterflies, has the opposite effect on mosquitoes and other pesky insects. But that’s the case with bee balm (Monarda spp.)

      Fast-growing with bright abundant blooms, this perennial does well outdoors and attracts plenty of desirable pollinators like bees and butterflies. At the same time, its fresh scent is a deterrent to mosquitos, especially if you crush some leaves between your palms. For best results, crush a few leaves to release the scented oils.

      Allium, also known as ornamental onion, are perennial bulbs that share a scent similar to table onions, garlic, and chives, which are also members of the same family. Allium is among a small handful of plants that repel mosquitoes simply by their presence in the garden. Along with repelling mosquitoes and other pests, allium plants add an exotic appeal through their unusual, globe-shaped flower clusters.

      Warning

      These plants are mildly toxic, however, so be careful if you have pets that like to gnaw on plants.

      The tiny white flowers of Callicarpa americana aren’t much to look at, but the vibrant magenta berry clusters make this small shrub stand out in the landscape. Beautyberry plants are a member of the Lamiaceae family, which includes many mints. The fragrant oils released by crushing the leaves of the beautyberry repel mosquitoes, and the berries often last long into the winter to attract and feed songbirds and small mammals.

      Catnip

      Catnip does more than just delight your feline companions. It’s a member of the mint family, but looks and smells a bit different than your typical mint varieties—though works just as well as a pest deterrent! Fast and easy to grow, they’re also prone to taking over patches of your garden, so stick to containers—or be ready for lots of catnip in a hurry.

      Lemongrass

      Somehow, the natural oils in Cymbopogon citratus manage to smell like real lemons, only better. Grassy and abundant with a bright citrus scent, lemongrass is known for its higher potency of citronelal, the oil that deters mosquitoes.

      Versatile for use in cooking and adding lovely fragrance to your porch, you can cut some fronds and scatter them nearby before a gathering to help repel mosquitos. Coarsely chop the strappy leaves of this plant and strew them around your deck during your next gathering, both for mosquito-repelling power and for the pleasing aroma.

      These bright and summery flowers, a staple for annual lovers, also happen to help with your mosquito-fighting goals. The substance in marigolds that gives them their insect-repelling power is pyrethrum, the same substance used in many organic insecticides.

      Liven up your patio with multi-colored blooms, especially around the borders of your patio, balcony, or yard, because these flowers are incredibly powerful at keeping pests away. In fact, studies have shown they have a negative effect on more than just mosquitos, deterring aphids, thrips, squash bugs, and many other garden destroyers.

      Lantana (Lantana camara) flowers have such a potent effect against mosquitoes a scholarly journal published a report about it. The Journal of the American Mosquito ControlAssociation (yes, there is such a journal) shares that “lantana flower extract in coconut oil provided 94.5 percent protection from Aedes albopictus and Ae. aegypti” mosquitoes. In fact, the study found this oil preparation protected the users from mosquitoes for an average of two hours. What a bonus that lantana flowers are so easy to grow in warm sunny locales, and attract butterflies as well.

      Fennel

      An under-appreciated herb for home gardeners, fennel is delicious, fragrant, and versatile in the kitchen. The leaves host swallowtail butterfly caterpillars in the garden, and not to mention, it’s thought to help fight mosquitos away.

      The plants grow large and grassy in appearance, providing a similar look and coverage as ornamental grass, but with beneficial bonuses. Hardy and perennial, these plants thrive in plenty of full sun.

      Eucalyptus

      As a native tree in Australia, the eucalyptus tree (Eucalyptus cinerea) can soar to 60 feet tall after several years. Because it’s a tender plant that won’t survive a hard freeze, the better alternative for many gardeners is to grow the eucalyptus as a potted plant. For short-term potting, choose a quick-growing species like E. globulus subsp.bicostata, which will give you many fragrant leaves to harvest for mosquito repelling. For a plant that will live for several years in a pot, choose a slow-growing eucalyptus like E. vernicosa. Eucalyptus plants like full sun and rich soil.

      This beloved herb, famous for enhancing Italian dishes, sauces, and more, also happens to play a secret second role as mosquito repellant. The pests are repulsed by basil leaves, while humans love their bright fragrance and ability to improve many dishes. Fickle in some climates, basil thrives best with plenty of full sun and moist, well-draining soil.

      Not all basil types are created equal when it comes to repelling mosquitoes, and the extra-spicy Thai basil, with its narrow foliage and cinnamon scent, has the best ability to fend off insects.

      Thyme continues the list of savory herbs that repel mosquitoes. Plant thyme between stepping stones in the garden, where your steps will crush some leaves and release the mosquito-repelling oils.

      Scented geraniums include many varieties of Pelargonium (garden geranium) bred for their pungent scent. Those with a lemon scent are known to be best for repelling mosquitoes and other insects. Scented geraniums are perennial in warmer climates but are more often grown as annuals. They are especially popular as potted plants.

      Ageratum, commonly known as floss flower, contains a chemical known as coumarin, which can repel mosquitoes just by growing in the garden. Planting ageratum around a patio or in pots on your deck will help discourage mosquitoes. The same chemical makes the plant toxic, though, so be wary if you have pets that like to chew on plants. Ageratum was once primarily a low bedding plant, but there are now cultivars such as ‘Blue Horizon’ that grow to heights of 2 feet or more, giving you more options for using them in your gardening.

      Sage (Salvia officinalis) is a perennial herb with a semi-shrubby growth habit. It has a pungent yet pleasant odor that mosquitoes avoid. Leaves tossed into a fire pit will keep bugs away for hours. Over time, garden plants can become woody and sparse; prevent this by dividing the plants every few years.

      Another member of the Allium family of plants, garlic works in the same way as ornamental allium, offering some protective value against mosquitoes merely by growing in the garden. Like other members of the allium family, garlic is toxic to animals, so make sure your pets don’t gnaw on the leaves, flowers, or bulbs.

      Pennyroyal (Mentha pulegium) is a spreading ground cover plant closely related to spearmint. Its scent is similar to that plant, and is so repugnant to mosquitoes that this species is sometimes called mosquito plant. It is not an especially attractive garden specimen, but it makes for an easy-care, effective ground cover, emitting a bug-repelling scent whenever you step on it. This is one of the most effective of all bug-repelling plants, but avoid growing it where pets might chew on it—the oils are toxic.
