As an introduced commensal, Indiana house-mouse records are centered on buildings, barns, warehouses, and disturbed edges rather than natural destinations such as Indiana Dunes or Pokagon. Reports occur year-round with peaks in March, August, and November, but those dates may track indoor encounters and reporting behavior more than outdoor seasonality.
The 55 iNaturalist records document photographed mice, not house-mouse abundance. Most animals in occupied structures are never submitted, identification can be difficult, and reporting effort follows people, so the Indiana dataset is a sparse presence record rather than a population sample.
