Which form of rodenticide formulation is potentially more hazardous and must be applied with extra caution?

Tracking powder is considered potentially more hazardous because it can easily be spread by environmental factors such as wind, rain, or movement of non-target animals, increasing the risk of unintended exposure to pets, wildlife, and even humans. Unlike solid baits, tracking powders consist of fine particles that can adhere to fur or be inhaled, making them a concern in terms of safety.

Additionally, tracking powder is designed to be very palatable to rodents, which means it can attract them readily; however, this same palatability can pose risks to non-target species that may ingest it accidentally. The application of tracking powder requires additional precautions, such as ensuring it is placed in areas that are not accessible to non-target animals, applying it in limited quantities, and cleaning up any spills to minimize exposure.

Other formulations like granular bait, liquid concentrate, and block bait have more defined application methods and are generally more contained, posing less risk of accidental exposure compared to tracking powder. This makes tracking powder necessitate a heightened level of caution during its use.
