Maryland Category 7D – Rodent Control Practice Exam 2026 - Free Rodent Control Questions on Biology, Inspection, and IPM Strategies

Illumination is essential for seeing what’s hidden. Rodent activity takes place in dark, tight spaces—behind cabinets, inside walls, crawl spaces, attics, and other secluded corners. A flashlight lets you directly observe signs that would otherwise be invisible, such as fresh droppings, rub marks, grease trails, gnaw marks, nests, and entry points. With a focused light, you can follow runways, verify whether signs are recent, and reliably assess where rodents are entering or harborage is located. That visibility is what drives accurate inspections and effective IPM decisions, making the flashlight the most important inspection tool. While it can help reveal droppings, its real value is illuminating all signs of activity and access points that guide treatment. Temperature assessment, for example, isn’t something a flashlight accomplishes.
