Have you ever thought of planting some insect-repelling plants in your garden? Summer is the season for mosquitoes, bugs, insects and other itch-inducing pests to come out in full force, harming your skin and leaving your fingers frantically scratching away, desperate for a little relief. Fortunately, there are some plants that insects hate- mint, basil, bay leaves, catnip, citronella, lemon balm and lavender. Actually, these plants contain some kind of insect repellent oils; they gradually carry small quantities of this oil to their leaves and release it in air. And this acts as natural insect repellent.
