Natural Alternatives to Pesticides

Many chemical pesticides on the market work only on adult bugs. That means that multiple applications of the chemicals will have to be used, since they wouldn't harm the immature pests or eggs. Also, insects have been building up resistances to the chemicals, so higher and higher concentrations have to be used to maintain effectiveness. Fortunately, there are many natural alternatives to chemical pesticides that can be used on large or small scales.

This Green Times article provides tips for maintaining a healthy, chemical-free garden.  For instance, bringing in ladybugs is recommended to eliminate aphids, grubs, and other pests that want to chew up your plants. You can buy them in stores, live and packaged, or plant flowers that will attract ladybugs, and other beneficial insects, to your garden.

You can also make use of plants that have natural insect-repelling qualities, like garlic or marigolds. 

It also helps to make an environment friendly to the "good bugs," as well as lizards, frogs, and birds, who will help keep the pest population in check. You can do this by giving up chemical fertilizers (and pesticides, of course) and having hiding places for these creatures, such as shrubs or leaves on the ground. They also appreciate the occasional strategically-placed water dish.
