Lemongrass is a common ingredient in many natural mosquito repellents. It contains citronella oil, which is known for its insect-repelling properties. Citronella oil masks the scents that mosquitoes are attracted to, making it difficult for them to locate and bite humans. Additionally, lemongrass has a strong scent that is pleasant to humans, making it a popular choice for natural mosquito repellents. It can be used in various forms such as oil, candles, and even as a plant in gardens and outdoor spaces.
