How many doses does a "second generation" rodenticide typically require to kill?

A "second generation" rodenticide is designed to be more potent and has a cumulative effect, meaning it can kill rodents after they consume it over a period of time. Typically, secondary generation rodenticides require only one dose to be effective, which contributes to their increased toxicity compared to first generation rodenticides. This rapid lethality is particularly beneficial in controlling rodent populations more efficiently.

The mechanism involves the accumulation of the active ingredient in the rodent's body, leading to death after just one feeding, provided the dose is sufficient. This characteristic makes second generation rodenticides a popular choice among pest control professionals, as they are often more effective than their first-generation counterparts, which generally require multiple doses to achieve a lethal effect.
