Dealing with pests is one of the biggest problem of organic gardeners. An infestation of aphids or cutworms can absolutely devastate a garden. An entire row of plants can be wiped out in a matter of days or even hours.

Hence, prevention of infestations rather than treating them as and when they occur is crucial. This can be done by spraying your plants with solutions that deter many of the most common garden pests. There are many organic solutions available. However, you can make your own by using recipes that can be found in most organic gardening books. Most of them are similar to tea and are concocted with ingredients like hot pepper sauce and garlic.

Organic or Biological Control of pests in agriculture is a method of controlling pests including insects, mites, weeds and plant diseases that relies on predation, herbivory, parasitism or other natural mechanisms. Biological Control reduces pest populations by using natural enemies of the pests and typically involves active human participation. Classical Biological Control is the introduction of natural enemies to a new locale where they did not originate or do not occur naturally. One of the earliest success of biological control was with the cottony cushion scale, a pest that was devastating the California citrus industry in the late 1800s. The vedalia beetle, a predatory insect and a parasitoid fly were brought in from Australia. Within a few years, the cottony cushion scale was completely controlled by these introduced natural enemies.
