Essential oils as insect repellent are a natural alternative to commercial products that usually contain chemicals such as DEET. Many essential oils have repellent properties that can help keep mosquitoes, flies, fleas, ticks, and other insects away in a safe, non-toxic way.

How Do Essential Oils Work as a Repellent?

Essential oils contain aromatic compounds that act as natural defenders of plants, helping them repel insects. These same compounds can interfere with the insects' detection system, making them less likely to approach areas where the oils are applied.
