Lemongrass, scientifically named Cymbopogon citratus, is a grassy weed that can grow to be about 4 feet tall and produces an oil that people have been using for decades as both food additive and pesticide to keep away pests.

Lemongrass has been used extensively for centuries by humans as well as animals. Some pet owners put lemongrass into their pets’ collars because it kills fleas and other bugs on contact, preventing harmful diseases spread by parasites like Lyme disease or Rocky Mountain spotted fever. The herb also repels mosquitoes; if you rub the plant onto your skin, mosquitoes will steer clear.
If you’re trying to prevent bug bites and keep your yard pest-free, try planting lemongrass near your house. If you don’t have any space for a garden, simply buy the plant and place it in a pot outside.
