There are plants which help repel insects, But know that simply including some of these plants in your won’t get rid of every pest.
As a matter of fact, the best thing you can do to battle mosquitoes is to remove standing water from the garden. I also use something called mosquito dunks. They are organic and are put into water to kill the larvae of the insects.
Plants with a high concentration of essential oils are usually avoided by insects, therefore, planting them should help in the battle against insects.
Basil repels house flies and mosquitoes. Since it’s so easy to grow, fill pots with the herb and put them around areas outside.
Lavender repels moths, fleas, flies and mosquitoes. Although people love the smell of lavender, mosquitoes, flies and other unwanted insects hate it. Grow it in a sunny location.
Lemongrass repels mosquitoes. Citronella is a natural oil found in lemongrass, an ornamental that can grow up to 4 feet tall and 3 feet wide in one season, it’s grown as an annual.
Mint and rosemary repel mosquitoes. Never plant mint in the garden, it will take over, always grow it in a pot. I always plug the drainage hole as the mint can escape that way too.
Rosemary has a wonderful perfume that helps keep mosquitoes away.
Dill repels aphids, squash bugs, spider mites, cabbage loopers and tomato hornworms. It also attracts good pollinators to the garden and once you have dill, you’ll always have dill as it reseeds prolifically.
Nasturtiums repel whiteflies, squash bugs, aphids, many beetles and cabbage loopers.
Science tell us these plants will help keep some of the bugs at bay, but no one knows to what extent. Enjoy the plants and hopefully they will battle the pests too.
