Plants That Attract Beneficial Insects
Nature is filled with "good bugs", crawling and flying creatures whose diet consists mainly of the pests that ravage garden plants. Here is a list of those good bugs and the plants that they like to visit for food and shelter. Intersperse these plants among the "problem pest areas" in your yard. Remember, though: Many chemical sprays work on both bad and good bugs. To keep the good bugs in your yard, eliminate insecticide use in the areas where they live and work.
