Why are poisonous baits often used in small amounts?

The reason poisonous baits are often used in small amounts is closely related to their high toxicity. When a bait is formulated to be potent, even a small quantity can effectively kill or eliminate targeted pests. This concentrated approach ensures that only minimal amounts are necessary to achieve pest control objectives, making the process both efficient and cost-effective.

Using small amounts also helps in minimizing potential risks to non-target animals and the environment. By applying only what is necessary, applicators reduce the likelihood that other wildlife or pets will encounter and ingest substantial quantities of the bait, which could lead to unintended negative consequences. Ultimately, the small use of high-toxicity baits balances effective pest management with safety considerations.

In contrast, while it is true that baits should be placed where pests are likely to gather, this does not provide the primary rationale for their small usage amounts. Reducing environmental impact is a consideration, but it primarily stems from the need to manage how much of a toxic substance is released into the environment. The focus on toxicity itself clarifies why small amounts are sufficient for effective pest control.
