Maryland Category 7D – Rodent Control Biology, Inspection, And IPM Strategies Practice Exam

Storing food in sealed containers with tight lids and keeping it off the floor best deters rodents because it removes both easy access and strong odor cues that attract them. When food is in airtight containers, rodents can’t smell or gnaw their way into the contents, which interrupts their ability to locate and consume food. Keeping storage off the floor reduces damp, clutter, and hidden harborage, making it harder for rodents to travel, nest, or hide behind stacks. In contrast, leaving food exposed on open shelves, placing it near waste bins, or storing it in unsealed bags creates obvious pathways and attractants that invite infestation. Together, sealed off-the-ground storage aligns with effective sanitation and exclusion practices that are central to preventing rodent problems.
