Often dark and damp, basements are the major entry point for utilities in homes and apartment buildings, and often have drains or sump pumps in the floors. Add in all those dark, ignored corners, and boxes of stored, often forgotten, items, and you’re providing nesting and occasional food sources for many types of pests.
