NatureServe classifies the house mouse as exotic in Florida, and its 432 state records likely include escaped or human-associated animals, since there’s no evidence of a self-sustaining wild population here. Most of that total, 409 records, comes from GBIF rather than casual iNaturalist sightings.
Reports rise sharply into June, the year’s high point, before dropping off through late summer and fall. That midyear jump likely reflects survey or trapping activity around human structures, not a true peak in when house mice are active in Florida.
