Norway Rat – Connecticut Identification & Burrowing Behavior Guide

The Norway rat, also known as the brown rat, is the primary rat species found in Connecticut homes and businesses. Larger, stronger, and more destructive than mice, they are most often found near foundations, basements, restaurants, and dumpsters.

Identification:

• Size: 10–12 inches (body + tail)
• Color: Brown/gray, muscular build
• Tail: Thick, shorter than body
• Droppings: Capsule-shaped, blunt ends

Behavior & Habitat:

Norway rats:

• Burrow under decks, porches, garages, sheds
• Live in basements or crawlspaces
• Travel along foundation lines
• Chew aggressively to enter structures

Common in urban CT towns:

• Hartford
• New Britain
• East Hartford
• West Hartford

Why Rats Invade:

• Dumpster overflow
• Bird feeders
• Pet food
• Poor sanitation
• Structural gaps

Health Risks:

• Leptospirosis
• Salmonella contamination
• Risk of electrical fires
• Aggressive biting when cornered

Why DIY Fails:

Rats are trap-shy, intelligent, and avoid new objects (neophobia). Amateur bait placement often leads to avoidance behavior.

When to Call a Professional:

Any rat activity should be handled professionally—especially if burrows reappear daily.
