How long does it typically take for anticoagulant baits to take effect, and how many feedings are usually required?

• A. 5-15 days; multiple feedings
• B. 1 day; single feeding
• C. 30 days; single feeding
• D. 2 hours; immediate effect

Answer: (A)

Anticoagulant baits produce their effect only after the rodent has ingested enough toxin to disrupt its blood-clotting system over time. The poisoning accumulates with repeated feedings, so death is typically seen after several days to a couple of weeks. That’s why the standard description is a timeframe of about 5–15 days with multiple feedings required. The other options imply an immediate or single-dose kill, which doesn’t match how these baits work, since a lethal dose is usually reached only after several meals.
