Keeping insects away without using chemical pesticides is possible with natural repellent plants. These plants not only deter mosquitoes, flies, and pests but also add beauty and fragrance to your home and garden.
In this guide, you’ll learn which plants work as natural insect repellents, how to grow them, and the best ways to use them to protect your home and garden naturally.
1. How Do Repellent Plants Work?
Natural repellent plants produce strong scents and essential oils that insects dislike. These plants work in different ways:

✔ Attracting beneficial insects that prey on harmful pests.
🌟 Tip: Planting repellent plants near doors, windows, patios, or vegetable gardens helps create a natural barrier against insects.
