Southern Living's editorial guidelines Published on May 28, 2024 Close Photo: Getty Images I’ve always said that I’d spend more time outside if there were less bugs. There are some people who can ignore or even embrace them, but I’m simply not one of those people. As the mom to an active toddler, however, I find myself spending more and more time with Mother Nature. Through all my research on how to make myself (and my yard) less attractive to pests, I discovered that plants are actually our secret weapon—more specifically, the scent of plants. The trick is that you have to bruise the leaves to get the valuable essential oils out, whether by rubbing, crushing, or even burning them. If you feel the same way I do about the outdoors, these are the ones you should consider growing. How To Keep Bed Bugs Away, According To Experts Meet The Experts Rebecca Sears, CMO & Resident Green Thumb at Ferry-Morse Kelly Dyer, Plant Doctor and Horticultural Expert at Patch Plants Hector Manuel Sanchez Marigold Botanical Name: Tagetes spp.Sun Exposure: FullSoil Type: Well-drainedSoil pH: 6.0-7.0 “A hardy annual, marigolds are easy to grow, showcase bright pops of color, and have a distinctive aroma,” explains Rebecca Sears, CMO & Resident Green Thumb at Ferry-Morse. In fact, they contain Pyrethrum, which is a compound used in many insect repellent products (marigolds specifically are good at deterring flies, mosquitoes, aphids, and black/whiteflies). According to Kelly Dyer, Plant Doctor and Horticultural Expert at Patch Plants, you can plant it in late April-early May after any risk of frost has passed. “They’re great in combined planters on a patio, along the front of borders, and interplanted amongst vegetables as a companion plant,” Dyer says.

Whether you opt for a tree or shrub, Dyer says they should be planted in spring or fall and pruned regularly to keep their growth in check and maintain their shape. Hector Sanchez 12 Plants That Repel Mosquitoes Basil Botanical Name: Ocimum basilicumSun Exposure: FullSoil Type: Moist, well-drainedSoil pH: 6.0-7.5 A garden staple that’s easy to grow, Sears says basil’s a popular mosquito deterrent because of the natural compounds estragole, citronellal, limonene, and nerolidol. “It also repels tomato hornworm, making it the perfect companion plant for tomatoes,” she adds. “Basil seeds can be started indoors in a sunny spot six weeks before transplanting, or you can sow them directly in your garden when the last frost has passed and the ground is warm.” anskuw/Getty Images Lavender Botanical Name: Lavandula spp.Sun Exposure: FullSoil Type: Well-drained, sandy, rockySoil pH: 6.5-7.5 Bees and humans enjoy lavender, but Dyer says the essential oil compounds—linalool and linalyl acetate—released in hot temperatures are “confusing, and even better, repelling to flies, mosquitoes, and moths.” Sears recommends starting your lavender seeds indoors near a sunny window in mid-March or early April, then transplanting it six weeks later. “It’s great planted in pots alone or in mixed planters, but does equally well in the ground at the front of beds,” Dyer adds. Cut back or harvest spent flower heads in the fall to encourage new growth. janaph / Getty Images Rosemary Botanical Name: Salvia rosmarinusSun Exposure: FullSoil Type: Well-drainedSoil pH: 6.0-7.0 With its strong scent courtesy of a compound called eucalyptol, pests like cabbage moths, beetles, mosquitos, and snails are scared away. Alpha-pinene, camphor, and limonene are three more of rosemary’s compounds with magical insect-repelling properties.

When it comes to planting, you have options: start the seeds indoors approximately 4-6 weeks before the last frost (think early-middle spring), sow them outdoors during the fall or late spring, or plant it outdoors in the late spring or early summer when you’re certain the last frost has passed and the weather has warmed up. Getty Images Mint Botanical Name: MenthaSun Exposure: Full, partialSoil Type: Well-drained, moist, sandySoil pH: 6.0-7.0 Between the menthone, menthol, and methyl esters in the essential oil, Sears says mint can keep away a number of pests like mosquitos, flea beetles, fleas, white cabbage moths, aphids, ants, and even rodents. The catch? “Mint is a highly invasive perennial, so I recommend planting it in a container to keep it from spreading.” Getty Images. Scented Geranium Botanical Name: Pelargonium spp.Sun Exposure: FullSoil Type: Well-drained, moistSoil pH: 6.0-6.8 A popular flower you might already have, the scented geranium is particularly effective at deterring mosquitos and flies. According to Dyer, the primary essential oil compound is geraniol, which creates a pleasant fragrance for us, but not certain insects—though long-tongued pollinators like butterflies love it. “This flower is not frost tolerant, so it either needs to be brought into a conservatory over winter and/or planted out after any risk of frost has passed,” Dyer advises. She likes to put them in pots on a balcony or outdoor seating area. gaiamoments/Getty Images Thyme Botanical Name: Thymus vulgarisSun Exposure: FullSoil Type: Well-drained, rocky, sandySoil pH: 6.0-8.0 Mosquitos, whiteflies, earworms, maggots, hornworms—these pests all share a dislike for thyme. A bonus given the herb’s delicious role in the kitchen, this is all thanks to the citronellal essential oil compound inside the leaves. Norma Murace Melia / EyeEm / Getty Images Sage Botanical Name: Salvia officinalisSun Exposure: Well-drainedSoil Type: Well-drained, rocky, sandySoil pH: 6.5-8.0 Rosemary and sage deter many of the same pests, so you might not necessarily need to grow both (though your home-cooked meals may disagree). Beetles, flea beetles, carrot flies, snails, and cabbage moths will all be deterred by the herb. That said, you’ll want to keep it away from rue, cucumbers, and onions. peplow / Getty Images Catnip Botanical Name: Nepeta catariaSun Exposure: Full, partialSoil Type: Well-drainedSoil pH: 6.0-7.8 Named for how much cats love it, catnip is a member of the mint family. “It contains a compound called nepetalactone that repels insects such as mosquitoes, flies, and deer ticks,” Sears explains. Just like mint, catnip is an aggressive grower, which is why she recommends planting it in a container as well. Cavan Images/Getty Images Peppermint Botanical Name: Mentha x piperitaSun Exposure: PartialSoil Type: Moist, well-drained, richSoil pH: 6.0-7.0 Peppermint is incredibly invasive, but it can also be equally effective in keeping fleas, flies, and spiders away. This is because the scent comes off very strong and is too much for them to bear. Because of its invasiveness, peppermint needs to be isolated in its own container. Was this page helpful?
