Mice and rats in Nashville homes
Nashville homes attract more than one rodent species, and house mice, deer mice, roof rats, and Norway rats each require a different control approach. Getting the ID right before acting matters.
1Disease risk
Deer Mouse
IDBrown back with sharply contrasting pale underbelly; large rounded ears; two-tone tail
WherePrimarily outdoors; enters homes during cold snaps, nests in attics and crawl spaces
NoteDeer mice can carry hantavirus in some regions. Avoid sweeping dry droppings — particles released into the air pose an inhalation risk.
2Gnaws wiring
Roof Rat
IDSlender body, long tail longer than head and body combined; large ears; darker coat
WhereAttics, soffits, and rooflines; travels along tree branches and overhead utility lines
NoteRoof rats work high in the structure, which means damage to wiring and insulation can go unnoticed until it’s extensive. Active at night along overhead travel routes.
3Disease risk
Norway Rat
IDHeavy, blunt-nosed body; tail shorter than body length; coarser brown-gray fur
WhereGround level — foundation perimeters, crawl spaces, under sheds and debris piles; digs burrows
NoteNorway rats stay low and burrow near foundations. Droppings are noticeably larger than mouse droppings, which helps distinguish them from mice quickly.
4Contaminates
House Mouse
IDUniform grayish-brown coat with no two-tone contrast; small pointed nose; pepper-like droppings
WhereKitchens, garages, storage areas; nests behind appliances and inside wall voids
NoteHouse mice contaminate pantry shelves and stored food with droppings and urine. They breed rapidly — a small sighting can indicate a larger hidden population.
