The most important principle of pest control is this:
Use a pest control method only when that method will prevent the pest
from causing more damage than is reasonable to accept.
Even though a pest is present, it may not do very much harm. It could
cost more to control the pest than would be lost because of the pest's damage.
The three main objectives of pest control are:
prevention—keeping a pest from becoming a problem
suppression—reducing pest numbers or damage to an acceptable level
eradication—destroying an entire pest population.

PEST CONTROL METHODS
The use of a combination of methods to control pests is basic to all pest
control. Successful pest control is based on the ability to:
keep pest damage to a minimum by choosing an appropriate combination
of control methods
recognize when direct action, such as a pesticide application, is necessary
cause as little danger as possible to the environment
The combination of methods you chosen will depend on the kind and
amount of control needed.

NATURAL FORCES
Some natural forces act on pests, causing the populations to rise and fall.
These natural forces act independently of humans and may either help or hinder
pest control. You usually cannot alter the action of natural forces on a pest
