Maryland Rodent Control Practice Exam 2026: Biology, Inspection, and IPM Strategies

Tracking powders are dry materials used to follow rodent activity, and they can become easily airborne and contaminate food or food-contact surfaces. The safest precaution is to keep them away from any food areas and places where air movement could carry the powder, applying them only in protected spots such as cracks, crevices, along walls, or behind equipment where they won’t drift into food handling areas. This minimizes the risk of ingestion or inhalation by people and non-target animals while still allowing effective monitoring of rodent activity.

Mixing with water isn’t how tracking powders should be used, and storing in a freezer isn’t necessary for these products. Using them near food areas would risk contamination, which is exactly what this precaution aims to prevent.
