Most pests can be controlled during one particular life stage.

• A. True
• B. False
• C. Only at Egg Stage
• D. Only at Adult Stage

Answer: (A)

Pests are often most susceptible to pesticides during a specific life stage. As pests move through eggs, immature forms, and adults, their biology and behavior change, creating a stage where a pesticide can work best. Treatments are usually timed to hit that vulnerable stage when the pest is most exposed or physiologically receptive—such as a actively feeding larva or nymph, or, for some products, the egg when an ovicidal option is used. Because of this targeted vulnerability, effective control is often achieved by treating just that one stage, making the statement true. There are cases where multiple stages need attention, but the practical approach is to focus on the life stage where the pest is most susceptible for efficient control.
