Most insect-repelling herbs do so with their natural fragrances, which keep annoying mosquitoes away and introduce wonderful scents throughout your garden. Essential oils in these plants act as nature’s insect repellent. Mosquitoes and other insects tend to avoid them (these oils are released when you rub the leaves or buds of the plant on your skin which may cause irritation to some to test on a small patch of your skin before you rub the herb all over). But know that simply including insect-repelling plants in your landscape will not in itself ensure your garden is insect free. In addition to growing the plants listed below, you should also practice good mosquito control in your garden so that the pests don’t get out of hand. The best thing you can do is prevent water from collecting and becoming stagnant, mosquitoes can lay hundreds of eggs even in a tiny spoonful of standing water. You can even use some of these plants to make your own natural mosquito repellent.
