What are the two major categories of rodenticides?

The two major categories of rodenticides are appropriately identified as single dose poisons and multiple dose anticoagulants. Single dose poisons are designed to be lethal after the rodent consumes a single amount, making them effective for immediate control. These types of rodenticides often act quickly to stop various bodily functions, leading to the death of the rodent shortly after ingestion.

On the other hand, multiple dose anticoagulants require the rodent to consume a series of doses over several days to achieve a lethal effect. These anticoagulants work by disrupting the rodent’s blood clotting ability, leading to internal bleeding and ultimately death after prolonged exposure.

This classification is essential for pest management professionals as it informs their selection of rodenticides based on the specific needs of the situation, whether immediate action is necessary or if a slower, baiting strategy is more appropriate. Understanding these categories helps in the effective and responsible use of rodenticides, optimizing control while minimizing risks to non-target species and the environment.
