As warmer weather approaches, so does the season of outdoor activities—and pesky insects. While commercial insect repellents are effective, they often contain chemicals like DEET, which can be harsh on the skin and harmful to the environment. Fortunately, essential oils offer a natural alternative for keeping insects at bay. This article explores the best essential oils for insect repelling and how to use them effectively.

Essential oils are not only natural but also possess potent properties that insects find repellent. They are a safer option for those looking to avoid synthetic chemicals, making them suitable for individuals with sensitive skin, children, and eco-conscious consumers. Additionally, essential oils can provide a pleasant aroma, unlike many chemical repellents.
