Pennyroyal is a member of the mint family with an aroma that resembles that of spearmint. Growing pennyroyal in your back yard may keep mosquitoes at bay. However, it is important to keep in mind that the oils from this plant are extremely toxic to humans. The Poison Control Center warns against confusing this plant with its edible cousins. Consuming pennyroyal can lead to nausea, vomiting, bleeding, kidney or liver failure, and death. Nonetheless, if you are careful, pennyroyal can be an effective plant for keeping mosquitoes away.
Fortunately, not all plants in the mint family are poisonous. If planting pennyroyal seems too risky, you may prefer to add peppermint to your garden. Mosquitoes are repelled by the minty scent of this plant. Additionally, if you do happen to fall prey to a mosquito, Wish Garden Herbs suggest crushing peppermint leaves and applying them to the bite to soothe the itch. Mosquitoes aside, you can also enjoy the culinary benefits of this herb. The fresh taste of peppermint makes a great addition to teas, salads, and chocolate dips. You may be able to enjoy relaxing on your mosquito-free patio while enjoying a mint-infused mojito.
Rosemary is another plant that can provide you with multiple benefits. Whether you plant rosemary in your garden or keep it in a pot on your patio, the piney scent of this herb may help keep the mosquitoes away. Additionally, you can make your own natural mosquito repellent spray by steeping dried rosemary leaves in boiling water, straining out the leaves, and placing the liquid in a spray bottle. Finally, adding rosemary to your garden will provide you with a fresh source of this flavorful herb when cooking your favorite recipes.
