Here’s a good article on plants that repel bugs and mosquitos by Sarah Yang for Real Simple.
If you tend to spend long summer evenings hanging out on the patio or in the backyard, keeping bugs and mosquitoes at bay is probably a top priority. For pest control that will actually make your outdoor space look better, consider adding a few plants that repel mosquitoes. Whether you introduce pots of fragrant lavender around the perimeter of your patio or start planting citronella grass in your garden, these multi-tasking plants are both pretty and serve a purpose. For the best effect, be sure to position the plants as close as possible to the sitting area. Some lavender planted across the yard likely won’t help, but adding a few pots of lavender to your outdoor dining table could do the trick. Once you’ve stocked up on the plants that repel bugs and mosquitoes, below, arrange them carefully to maximize their bug-repelling potential.
Citronella Grass
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.”
Petunias
This perennial is sometimes known as “nature’s pesticide,” because it can repel aphids, tomato hornworms, 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.”
Give Your Bug Control A Boost
To really keep the bugs at bay, introduce a tried-and-true insect killer. Spectracide Triazicide Insect Killer for Lawns and Landscapes Concentrate kills more than 100 types of bugs. This powerful formula works against house crickets, carpenter ants, earwigs, and more, letting you enjoy a bug-free backyard. (As with all insecticides and other lawn and garden chemicals, read and follow all label instructions to ensure you use them safely.)
Lavender
“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.
Nasturtium
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.”
Rosemary
It not only adds flavor to your dishes, but it will also helps keep the bugs away. “This one is another plant perfect for summer heat because it likes to be dry,” Johnston says. “It is one of my absolute favorite smells, but mosquitoes can’t stand it. You can plant it in containers, but it also works well as a hedge.” Johnston says the plant also adds texture to arrangements, so why not place it in an outdoor centerpiece to repel bugs and provide some eye candy at the same time?
