plants that repel unwanted insects

Repels mosquitoes. This hardy herb can adapt to dry or rocky, shallow soil and will thrive in your herb garden, a rock garden or a front border as long as these are in sunny locations. The plant itself will not repel pesky mosquitoes. To release its chemicals, you must first bruise the leaves. To do this, simply cut off a few stems and rub them between your hands. Before you do that, though, it’s advisable to make sure the plant’s natural properties will not adversely affect you. Determine your tolerance by rubbing crushed leaves on a small area on your forearm for several days.
