Which rodenticide formulation is potentially more hazardous than others and must be applied with extra caution?

Tracking powder is potentially more hazardous than other formulations, largely due to its method of use and the risks associated with inhalation or dermal exposure. This formulation is designed to be applied in small quantities and is meant to adhere to the fur of rodents, where it can be ingested during grooming. While effective for targeting rodents, tracking powders can pose significant risks if they come into contact with non-target species or humans.

Extra caution is required during application to prevent accidental exposure, especially in settings where children, pets, or sensitive wildlife may be present. The potential for the powder to be inadvertently spread by wind or contact increases the need for stringent safety measures.

In contrast, granular bait, liquid concentrates, and powdered bait formulations have different pathways for rodent ingestion and application methods that might offer a more contained and controlled exposure risk when used as directed.
