Bugs aren’t all bad, and dousing your garden with pesticides is not only bad for the environment and your health, it kills the good bugs along with the bad. And you want the good bugs. Really!
One of the best methods of controlling unwanted pests is to invite their natural predators in. Besides, a garden full of bugs invites birds as well, and a pesticide-free garden is safer for butterflies and bees. All of these things promote organic gardening and improve the biodiversity of your yard. So, there’s the why, what about the how and what?
