The citronella candles on your patio are made with the oil that comes from this plant. “Citronella is by far the most popular plant that repels mosquitoes,” says Carmen Johnston, a garden lifestyle expert. “It has a very pungent odor. I often place this in small eight-inch terra cotta pots and mix in with my centerpieces when entertaining outdoors. You can either use the clippings mixed in with arrangements or use the plant itself as the centerpiece.”
This perennial is sometimes known as “nature’s pesticide,” because it can repel aphids, tomato hornworm, asparagus beetles, leafhoppers, and squash bugs. “Petunias are very easy to grow and you can plant them in the ground or keep them potted,” says Peyton Lambton, lifestyle expert and star of My New Old House. “They like sun, and I recommend buying transplants and placing them in light, well-drained soil in full sun after the last spring frost.”
“Lavender has a fragrant smell that deters mosquitoes,” Johnston says. “I have this planted in clusters at the entryway of my garden, and I love those purple blooms. It likes to be hot and dry, so it’s perfect for summer.” You can also apply lavender oil to your skin as a natural repellent.
It repels whiteflies, squash bugs, aphids, several beetles, and cabbage loopers. This one will help other plants in your garden, too. “They produce an airborne chemical that repels insects, protecting not only themselves but other plants in the grouping,” says Chris Lambton, a professional landscaper and star of My New Old House. “Plant these in early spring in moist, well-drained soil in full sun. They should be regularly watered and deadheaded to promote blooming.”
