Why does tracking powder kill rats?

Tracking powder is specifically designed to take advantage of a rat's grooming behavior. When rats come into contact with the powder, they inadvertently ingest it while cleaning themselves. The powder contains active ingredients that are harmful when ingested, but its delivery method is unique because it capitalizes on the natural instincts of the rats. As they groom, they accidentally consume the powdered substance, leading to its effectiveness as a control method.

This method is particularly useful because it can lead to a delayed effect, giving rats time to return to their nests and potentially affect other members of the population. The grooming behavior of rats is consistent, making tracking powder a strategic choice for pest control when carefully applied in areas where rats are likely to traverse.
