Norway Rats in Buffalo: Signs, Burrows and What Actually Works

By the Buffalo Pest Control team · Updated 2026-10-20

The Norway rat is the rat found across Buffalo and the surrounding suburbs. Knowing how it lives makes it much easier to keep it out of your building.

Identification

  • Body about 7 to 10 inches, plus a tail about as long.
  • Brown to gray fur, blunt nose and small ears.
  • Capsule shaped droppings about three quarters of an inch long.
  • Grease marks along baseboards, pipes and walls where bodies rub.

Where Norway rats live

They burrow in soil along foundations, under porches, slabs and sidewalks, beside trash areas and in garden beds. Burrow openings are roughly two to four inches wide with smooth edges and no spider webs.

In Buffalo, look for burrows along foundations, beside back porches, garages and trash areas and in garden beds. Rats also follow storm and sewer lines, so a burrow near a drain is worth reporting.

How they get inside

A Norway rat needs about a half inch gap. Common routes are foundation cracks, utility penetrations, gaps at cellar doors and broken or missing vent screens. Once inside, they use basements, crawl spaces and wall voids, and can reach upper floors along pipes.

When activity peaks

Rat activity tends to be most visible from late spring through early fall, while mice become the bigger indoor concern from the first freeze of fall through winter.

What actually removes them

  1. Inspect the exterior and interior to map burrows, runways and openings.
  2. Treat active burrows and use tamper resistant stations and traps on the runways.
  3. Seal entry points with metal and cement based materials.
  4. Cut off food and water: lidded trash, no outdoor pet food, repaired leaks.
  5. Monitor until activity reads zero.

Our rat control service follows this order, and our home exclusion guide covers the sealing details.

Frequently Asked Questions

How big is a Norway rat?

About 7 to 10 inches of body plus a tail of similar length, which is much larger than a mouse.

What do rat burrows look like?

Smooth edged holes about two to four inches wide in soil near foundations, porches, fences and trash areas, often with worn paths leading to them.

Why do rats come back after treatment?

Because the structure was not sealed and food or shelter is still available. Treatment and exclusion have to work together.
