No garden is immune to the effects of pests and diseases. But knowing your enemy can help you take steps to lessen, or even eradicate the damage caused by these garden foes.

Pests & Beneficials
A typical garden attracts hundreds of different species of insects, from beetles and caterpillars to bees, nematodes and moths. Only a few of these insects are pests, and many of the pests are only a problem during a specific part of their life cycle. The vast majority of the insects are "good bugs": predators, pollinators and parasites. The trick is knowing which ones cause damage and when, and learning ways to minimize that damage.
