Which statement about the use of anticoagulants is accurate?

Which statement about the use of anticoagulants is accurate?

• A. Used in most rodenticides today
• B. Used in some insect baits
• C. Used as plant fertilizer additive
• D. Used only in microbial pesticides

Answer: (A)

Anticoagulants are a type of active ingredient used to control rodents. They work by blocking the vitamin K–dependent clotting process, so ingested amounts slowly impair the rodent’s blood clotting, leading to internal bleeding after several days. This mechanism makes them highly effective for rodent control, which is why they’re used in most rodenticide formulations today. They aren’t used as plant fertilizer additives, they aren’t part of microbial pesticides, and they aren’t used in insect baits. When using them, proper placement in bait stations and attention to safety are important to protect pets, wildlife, and non-target animals.
