Mosquitoes have a sharp sense of smell. They are usually attracted to flowers, perfumes, and, most notably, the carbon dioxide and odor we emanate. In the same way, mosquitoes find certain aromas unappealing and tend to stay away from them. You can use such fragrances to prevent mosquito bites and stop the spread of diseases, especially when there are stagnant water bodies nearby. Here are five scents that repel mosquitoes: Citronella Citronella oil, extracted from the lemongrass plant, is typically utilized in commercial bug sprays. It includes a lemon-like citrusy fragrance that is bothersome to mosquitoes yet magnificently pleasing to humans. So plant lemongrass indoors as an effective mosquito repellent. You can also apply citronella oil to the skin or combine it with other essential oils to make your own DIY deterrent. Lavender Lavender might be the most loved aroma of many, but it is among the popular scents that repel mosquitoes. Mosquitoes hate the strong fragrance of the purple bloom and stay away from it. You can extract lavender oil and apply it to the skin or make a body spray. Some prefer growing the plant in their nursery. Rosemary Besides cooking, people use rosemary for many things. The multipurpose fragrant plant works wonders by taking care of minor mosquito invasions.
