Common examples include essential oils like citronella, peppermint, and eucalyptus, which can deter insects such as mosquitoes and ants. These repellents are often considered safer for humans and pets compared to synthetic chemicals. Many people use natural repellents in gardens or around their homes to create a more eco-friendly environment. They can be applied as sprays, candles, or even in the form of plants like marigolds that naturally repel certain pests. Overall, natural repellents offer a sustainable alternative for pest control.
