Why could a single dose of anticoagulant baits be more dangerous?

The option that indicates a single dose of anticoagulant baits is more dangerous because it poses a greater risk to non-target animals is grounded in the nature of anticoagulant poisons. These substances work by interfering with blood clotting mechanisms, which can be lethal even with a small amount for animals not intended to be targeted. When non-target species consume a single lethal dose, they can suffer significant harm or death, as they may be more susceptible to the effects of a one-time exposure compared to larger doses that are typically used in multi-feed scenarios.

Moreover, non-target animals, such as pets or wildlife, may easily come across these baits and ingest them, leading to unintentional fatalities. To mitigate these risks, many pest control strategies suggest the use of bait types that require multiple feedings, which allows for a lower overall dose to be effective and reduces the likelihood of accidental poisoning of non-target species.
