House mice are introduced commensal rodents in Mississippi, and NatureServe’s SNA rank, not applicable, reflects that introduced species don’t receive a state conservation status. Nearly all of the state’s 102 records, 99 of them, come from GBIF rather than casual photographs, meaning trapping and specimen collection, not people spotting mice, accounts for almost everything documented about this species here.
June and August are tied for the year’s peak, 19 sightings each, with October dropping to just 1, a pattern that likely reflects the timing of concentrated trapping surveys rather than any real seasonal shift in mouse activity, since house mice breed indoors year-round regardless of outside conditions.
