What is a key feature of non-anticoagulant rodenticides?

• A. They require multiple feedings for effectiveness
• B. They kill pests through various modes of action
• C. They are less toxic to pets
• D. They are always single-dose

Answer: (B)

A key feature of non-anticoagulant rodenticides is that they kill pests through various modes of action. Unlike anticoagulant rodenticides, which primarily work by affecting the blood's ability to clot, non-anticoagulants can operate through different biological mechanisms. For instance, some may cause neurological disruptions, metabolic interference, or other physiological impacts that lead to the pest's demise. This diversity in modes of action can make non-anticoagulants effective against rodent populations that may have developed resistance to anticoagulants. The other choices, while they contain some truths about rodenticides in general, do not specifically capture the essence of non-anticoagulant rodenticides. They do not necessarily require multiple feedings for effectiveness; some may be effective with a single dose. Additionally, while safety to pets can vary among different rodenticides, it is not a defining characteristic of non-anticoagulants as a group, nor are they exclusively single-dose since some may still require repeated feedings under certain conditions.
