Rattus norvegicus
Large brown rats that burrow at ground level near foundations, sewers, and waste areas — aggressive scavengers and vectors of disease.
40–50 cm (16–20 in); 340–450 g
Brown or grayish-brown fur with a lighter underside. Stocky heavy body, blunt snout, small ears and eyes, and a thick scaly tail shorter than head+body.
Cereals, grains, meat, sugary substances, food remnants, and waste. Requires water daily; survives ~4 days without food.
Ground-dwelling burrower. A breeding pair produces 6–12 litters per year (7–14 pups each), enabling rapid population growth.
Burrows near foundations, basements, sewer lines, storage rooms, under machinery, and in waste zones.
Transmit leptospirosis, salmonella, plague, and rat-bite fever. Damage wiring, plumbing, and structural materials.
Every norway rat engagement follows our proven three-step methodology — tailored precisely to this pest.
Inspect foundations, basements, sewer connections, and waste areas for burrows and droppings.
Deploy professional bait stations, traps, and rodenticides. Seal entry points ≥1.2 cm; remove food and water access.
Audit perimeter exclusion monthly and partner with municipal sewer baiting where applicable.
