CONTROLLING INSECTS
Control of insects and their relatives may involve any of the three basic
pest control objectives. Control is usually aimed at suppression of pests to
a point where the presence or damage level is acceptable. Prevention and
eradication are useful only in relatively small, confined areas such as indoors
or in programs designed to keep foreign pests out of a new area.
