Powder formulations used to track rodent movement are designed to reveal where rodents go and how they travel through an area. When you apply a fine tracking powder along suspected runways or entry points, rodents brush against it and leave behind dust on their fur and feet. By examining these traces—smudges, footprints, and paths—you can map activity patterns, identify how they move between buildings or rooms, and locate harborage and access points. This information is invaluable for tailoring a targeted IPM plan, such as sealing gaps, placing traps along the identified routes, or directing bait placement more effectively. Unlike tracking powders, other formulation types serve different purposes: baits are meant to attract and deliver poison when eaten; fumigants release toxic gas in enclosed spaces; and pellets are solid bait blocks designed for consumption. Tracking powders focus on monitoring movement rather than delivering a lethal dose, making them a diagnostic tool to guide subsequent control actions.
