Sources
for Norway Rat
How we know: Identification, biology, habitat, signs, damage, prevention, and control come from UC IPM (ipm.ucanr.edu) and University of Missouri Extension (extension.missouri.edu). Human-disease facts use two independent sources — UC IPM and CDC (cited only for disease transmission). Taxonomy follows ITIS, which lists Rattus norvegicus (Berkenhout, 1769) in family Muridae.
