What is an advantage of using anticoagulants for rodent control?

• A. They do not cause bait shyness
• B. They kill instantly
• C. They are non-toxic to non-target birds
• D. They require continuous feeding

Answer: (A)

Anticoagulants work by causing a gradual, cumulative effect. Because the kill doesn’t happen immediately, rodents don’t feel sick right away and aren’t warned to avoid the bait. This reduces bait shyness, since they don’t learn to associate the bait with illness after a single feeding. They may need several feedings to reach a lethal dose, so the bait remains attractive to enough individuals long enough to control the population. In contrast, quick-acting poisons can create visible illness or rapid death, which can lead survivors or others to avoid the bait. It’s also important to note that these products can pose risks to non-target wildlife, including birds, and they don’t rely on a single feeding to be effective, which is not an advantage in itself.
