What depth should tracking powders be applied to?

• A. 1/16 inch
• B. 1/8 inch
• C. 1/4 inch
• D. 1/2 inch

Answer: (A)

Tracking powders work by leaving a very light film that rodents brush against as they move; the powder sticks to fur and is ingested when they groom, helping transfer through their body and deliver the active ingredient. Applying a thin layer about one-sixteenth of an inch thick keeps that powder on travel surfaces without forming heavy piles. If the layer is much deeper, it can clump, create visible dust, and increase non-target exposure or waste; a layer that isn’t thick enough may not leave enough powder to transfer. That one-sixteenth-inch depth provides the right balance for effective tracking and safety.
