House mice are introduced commensal rodents in Arkansas, and NatureServe’s SNA rank, not applicable, reflects that introduced species don’t receive a state conservation status. The record leans toward GBIF (109 of 120 records), meaning trapping and specimen collection, not people spotting mice, accounts for most of what’s documented here.
November and December together account for 59 of the 120 records, nearly half the entire year’s total, with December alone at 38, a pattern that likely reflects a concentrated late-year trapping effort rather than any real seasonal shift in mouse activity, since house mice breed indoors year-round regardless of outside conditions.
