Which statement best defines a pest?

Which statement best defines a pest?

• A. Any organism that helps people
• B. Any organism that competes with people for food, fiber, space
• C. Only insects
• D. Only plants

Answer: (B)

In pest management, a pest is any organism that becomes undesirable because it competes with humans for resources or causes harm to our interests. The statement that best fits this idea is: any organism that competes with people for food, fiber, or space. This captures why pests matter—organisms that reduce what we have access to or damage property are pests, regardless of their type. It covers insects, rodents, weeds, fungi, and even microorganisms, all because their presence interferes with human resources or well-being. The other options are narrower or describe benefits or specific groups, which doesn’t align with how pests are defined in practice.
