A substance that acts as a poison to humans or wildlife is called?

• A. Toxicant
• B. Pesticide
• C. Insecticide
• D. Repellent

Answer: (A)

Understanding what a poisonous substance is helps here. A toxicant is any substance capable of causing toxic effects in humans or wildlife; in other words, it acts as a poison. Pesticide is a broad label for any chemical or biological agent used to manage pests, and while many pesticides are toxicants, the word emphasizes use rather than inherent toxicity. An insecticide is a type of pesticide specifically targeting insects, and a repellent is designed to deter pests rather than poison them. So the term that best fits a substance that acts as a poison to humans or wildlife is toxicant.
