Mosquito repellent plants = fewer summer swats
We all look forward to the weather warming up, but there’s one tradeoff for temperatures over 50 degrees: mosquitoes! Buzzing past your ear, leaving welts on your ankles, entering your room invisibly at night and preventing you from sleeping with their high-pitched whine…yes, mosquitoes are truly the bane of many a warm summer evening, and a spring and a fall one, too. (Wondering how long do mosquitoes live? Too long!). Many people prefer to avoid chemicals and pesticides such as DEET, but what are the alternatives if you want to discourage mosquitoes and other pests? Those candles don’t really seem to work, and the patches and bracelets are ineffective for a lot of people, but there’s one thing that humans have been using to for hundreds of years to keep the summer itchies to a minimum: mosquito repellent plants. It seems almost too easy, but planting certain types of herbs and flowers is a tried and true solution for the eternal problem of how to keep mosquitoes away. As a bonus, some that smell terrible to mosquitoes actually smell great to humans, so your patio dinner will be enhanced both by a lack of mosquitoes and by the sweet scent of flowers. These are the best mosquito repelling plants for a swat-free summer.

If you have a dry corner of your garden or windowsill that gets full sun, a rosemary bush will be very happy there. Just let it dry out between waterings, and it will reward you: firstly by flavoring your chicken and steak, and secondly as a mosquito repellent plant, driving insects away with its distinctive scent. Rubbing a few sprigs over exposed arms or legs will help to keep mosquitoes away from those areas, and rosemary smoke from a grill or fire pit will be an extra repellent.
Basil is not just for pizza toppings, pesto, and marinara sauce. This pretty herb also has major gardening benefits, like attracting bees, enhancing the flavor of other plants, and perhaps most important, as a mosquito repellent plant! Matteo Grader, a pest control specialist for the London-based pest control company Panther Pest Control, says gardeners highly recommend planting basil in the garden as a mosquito deterrent, thanks to its strong scent. Grader also recommends growing basil to make a natural mosquito repellent that won’t harm your other plants. To do this, take about 100 grams of fresh basil leaves, picked right from your garden. Pour a half-cup of boiling water onto the leaves, and then a half-cup of vodka. Mix thoroughly and add the mixture to a clean spray bottle. Spray your natural, basil-based repellent in your outdoor area to keep mosquitoes at bay.

Lemon balm contains a compound called citronellal, which has a very similar effect to the highly mosquito repellent citronella. The lemony scent of lemon balm is also one that mosquitoes don’t love, which makes it a perfect addition to your mosquito repellent plant collection. Juan J. Rocha, Vice President of DynaTrap, suggests caution when planting lemon balm in the garden, though, because of its invasive properties. It can spread quickly once planted, so it’s best to plant this one in pots, keeping them near the areas in your yard where you want to control the mosquito population—like the porch!
Your cat may go crazy for it, but mosquitoes will do anything to stay away from it. In fact, studies have shown that the essential oil in catnip, known as nepetalactone, is much more effective at repelling mosquitoes than store-bought bug sprays using DEET. The essential oil of catnip is so strong that you need about one-tenth as much of it as DEET for the same effectiveness. Catnip plants grow tall, so if you’re planting them directly in your garden, do so in an area where they won’t block your desired views. Also, be prepared to become the primary hangout for all the neighborhood kitties. Dog owners and people allergic to cats might need to look elsewhere on this list for the best mosquito repellent plants.

Pennyroyal is an extremely potent species of mint. If too much of its oil gets absorbed into the skin or consumed, it can be toxic to humans and animals. But when grown and used carefully, pennyroyal is one of the most effective mosquito repellent plants. You can plant a few pennyroyal plants close to the main gathering area of your outdoor space, like a seating area. Grader says that, for extra protection against mosquitoes, some people prefer to crush pennyroyal leaves and place them inside their pockets, where their strong odor still helps repel the pests. If you can’t find pennyroyal, mint plants in general are very effective against mosquitoes, including peppermint.
Citronella has long been favored as one of the most effective plants that repel mosquitoes, which is why outdoor candles and bug sprays are often made with its oils. You can plant citronella grass right into your garden, and optimize its efficiency by planting it near other mosquito repellent plants, like lavender. Citronella thrives in a variety of climates and soils, so it’s also one of the easiest plants to grow and maintain. If you see another plant with citronella on the label, citronella geranium, you’re in luck also: It’s a geranium that produces an oil very similar to citronella’s and has similar mosquito repelling effects. Citronella is often confused with lemongrass, as they are similar in appearance—the difference is the base stems, which are red or magenta on citronella and green on lemongrass. However, they both have intense mosquito repelling properties, so plant either one with abandon!

Native to the southern United States, this gorgeous shrub produces small white flowers and clusters of bright purple berries in the fall. The berries can be made into jellies and wine, and birds love them too, but the real magic of this mosquito repellent plant is its leaves. They’ve long been used as a folk remedy, and scientific studies have proven that a particular chemical compound in the plant’s leaves, callicarpenal, is extremely effective at repelling mosquitoes. And, as a bonus, it’s a great tick deterrent! Simply crush the leaves and rub them over your exposed skin (or your dog), and mosquitoes will want nothing to do with you. It’s also possible to purchase various bug sprays containing beautyberry essence, or make your own.

Who knew such a sweet-smelling flower would also be one of the best mosquito repellent plants? Fortunately, mosquitoes dislike most of the scents humans find pleasing, and lavender is one of them. Rocha explains that carbon dioxide is one of the most pleasant scents for female mosquitoes, since their main sources of blood meal, like humans and animals, emit the scent every time we breathe! The calming scent of lavender, however, is pretty far from CO2, and mosquitoes hate it. If you want to get your lavender doing double duty, use it as a natural mosquito repellent, placing a few drops on your wrists or ankles. If you can find it, the lavandin variety is particularly effective, as it’s high in camphor. Bonus: It also repels moths and flies!
One of the most beautifully simple flowers, marigolds bring more than just dashes of bright reds, oranges, and yellows to the garden. Their scent is also attractive to the human nose, but highly unattractive to mosquitoes. Amy Lawhorne, vice president of the tick and mosquito control company Mosquito Squad, suggests planting marigolds in pots to place near common mosquito entry points of the home, like windows and doorways. Or, place several pots of marigolds on your deck or main outdoor gathering area to keep mosquitoes away.

Garlic is one of the oldest remedies for repelling bad things. From vampires to mosquitoes, anything that wants to suck your blood will rapidly change its mind if you eat a few cloves a day. Most people don’t want to do that, however, but it’s easy to plant garlic instead. The strong scent of this mosquito repelling plant will keep your yard pest-free (and vampire-free, too).
How to make mosquito repellent plants work for you
As the weather gets warmer, it’s important to learn how to repel mosquitoes near your home by using your plants effectively. Your mosquito repelling plants can only be effective if you use them properly. Often, the best way to prevent mosquitoes from invading your space is to plant several repellent plants in a small area or plant them in pots, which can be easily moved to where you need them. “If you enjoy working in your garden, you may get some relief from mosquitoes by interspersing your repellent plants among your other plants to keep the mosquitoes off you while you garden,” Lawhorne suggests. Rocha stresses the importance of reducing the environmental factors that mosquitoes need to breed. He notes that you can do this by “getting rid of any sources of water where they may be able to hatch, including in wheelbarrows, buckets, dishes under flower pots, children’s wading pools, clogged rain gutters, over-irrigated lawns, used tires, and any other items that may collect water and thus [become] a place for mosquites to thrive.” So, with adequate drainage and a few new and attractive plantings, your summer evenings will become balmy instead of bug-balmy.
