Which of the following best describes a pest?

• A. Competes with humans, domestic animals or desirable plants for food or water
• B. Injures humans, animals, desirable plants, structures, or possessions
• C. Spreads disease to humans, domestic animals, wildlife, or desirable plants
• D. All of the above

Answer: (D)

A pest is any organism that causes or has the potential to cause harm by interfering with people’s resources, health, or property. It can compete for food or water with desirable plants or animals, reducing yield or performance. It can also directly injure humans, animals, crops, or structures. Additionally, many pests spread disease to people, livestock, wildlife, or plants, or act as vectors for pathogens. Because pests can cause damage in multiple ways, the description that includes all of these effects best defines a pest. In other words, anything that competes for resources, causes injury, or spreads disease falls under what we call a pest.
