Georgia’s black rat records concentrate almost entirely on the coast, on barrier islands like Cumberland and Sapelo and in the old port landscape around Savannah National Wildlife Refuge, tracing the same dockside pattern the species has followed since it first arrived on sailing ships centuries ago rather than spreading into the state’s interior. NatureServe flags the species as exotic, non-native, in Georgia, one of the few mammals on this atlas that isn’t part of the state’s original fauna.
It’s built for climbing rather than digging, a slim, long-tailed rat that moves through rafters, palms, vines, and utility lines more readily than it burrows into open ground. It feeds on almost anything at night, breeds quickly with litters of 3 to 5 young, and rarely lives more than about 4 years in the wild.
Georgia’s reports peak in January and November, the cooler months when rats are more likely to move into or near buildings for shelter, though records turn up in every month of the year. That pattern fits a species tied to structures and human activity rather than one following a natural seasonal cycle.
