Why are poisonous baits often used in small amounts?

The use of poisonous baits in small amounts is largely due to the high toxicity that some baits possess. Even a small quantity can be effective in controlling pest populations, as these substances are designed to be effective at low concentrations. This approach not only optimizes the application of the bait but also minimizes risks associated with over-application.

High toxicity means that the baits can achieve the desired level of pest control without needing large amounts that could be harmful to non-target species, including pets and beneficial organisms. Adopting this strategy helps maintain safety standards while effectively managing pest populations.

While other factors, such as the desire to limit potential interactions with non-target animals or to lessen the environmental impact, are important considerations in pest management, the primary rationale for using small amounts of poisonous baits primarily hinges on their potency.
