Virginia house-mouse records point toward the Coastal Plain, including Great Dismal Swamp, the Chesapeake Bay, and the Eastern Shore, though association with buildings makes the submitted map especially dependent on human attention. September supplies by far the largest monthly total and April a smaller secondary pulse; neither should be read as a statewide count of mice.
