Which two pieces of pest information are essential before selecting a vertebrate-control pesticide?

• A. An accurate identification of the pest species causing damage and knowledge of its habits and biology
• B. The latest market price and vendor rating
• C. Color of the pesticide and packaging type
• D. Soil pH and crop rotation history

Answer: (A)

Knowing exactly which vertebrate pest is causing damage and understanding its habits and biology are essential before choosing a pesticide. Different vertebrate pests require different active ingredients, formulations, and methods of application, and labels are specific to the target species and how that pest interacts with the environment. With accurate identification and knowledge of its behavior, you can select a product labeled for that pest, choose the right form (bait, repellent, or exclusion) and placement, and time the application to maximize effectiveness while minimizing risks to non-target animals and people. Price, packaging color, or soil conditions don’t determine the pest’s susceptibility or how you should apply the product, so they’re not essential factors for selecting a vertebrate-control pesticide.
