Norway rats are one of the most common—and troublesome—pests that homeowners and businesses face in urban areas. These persistent rodents not only damage property but also pose significant health risks due to the diseases they can carry. Living in Boston, where urban density creates a perfect environment for pests, spotting and controlling Norway rats can feel like a daunting task.

At Johnny B’s Pest Control, we’ve spent over 40 years helping Boston residents and businesses win the battle against pests like Norway rats. By understanding what to look for and taking prompt action, you can protect your home or workplace from these pesky invaders. Today, we’re sharing everything you need to know about identifying Norway rats and how we can help you get rid of them for good.

Who Are Norway Rats?

Norway rats, also known as brown rats, sewer rats, or street rats, are large rodents originally native to Asia but now found worldwide. They thrive in urban settings and are particularly common in Boston, where older buildings and proximity to the water create ideal nesting and feeding conditions.

At a glance, Norway rats have the following characteristics:

  • Size: Adult Norway rats typically measure 7-10 inches in body length, with an additional 6-8 inches of tail, making them one of the largest rodents you may encounter.
  • Build: Stocky and heavy-set, with a blunt nose and small ears covered by fur.
  • Color: Their fur is coarse and typically brown or grey, with a lighter underbelly.
  • Tail: Their tails are shorter than their body length and are covered in scales rather than fur, making them easy to distinguish from other rodents.

Knowing where Norway rats like to live and how they behave is another important step to identifying them correctly.

Signs Norway Rats Have Invaded Your Space

Norway rats are nocturnal creatures, meaning they’re most active during the night. While they prefer to stay hidden, their presence often leaves obvious signs, such as:

  1. Droppings

Rats leave behind droppings that are spindle-shaped and about ¾ of an inch in size. You’ll often find them along baseboards, near food sources, or in secluded corners.

  1. Gnaw Marks

Norway rats have strong teeth that grow constantly, so they gnaw on objects to keep them sharp. Look for chew marks on wood, wires, plastic, and even cement, as these could indicate a rat infestation.

  1. Burrows

Outdoors, Norway rats dig burrows around foundations, in gardens, or along riverbanks. Indoors, they may nest under floorboards or in crawl spaces.

  1. Grease Marks

Rats have oily fur. As they squeeze through tight spaces, they leave behind grease marks or smudges along walls and entry points.

  1. Noises

At night, you may hear scratching, scurrying, or squeaking sounds from within your walls, ceilings, or under the floor—telling signs of an infestation.

  1. Footprints or Tail Marks

If you suspect rats are present, sprinkle flour or baby powder near suspected entry points. The next morning, check for rat tracks or tail marks.

Once you’ve confirmed you’re dealing with a Norway rat issue, the next step is to act swiftly to prevent further damage.

Why Are Norway Rats Dangerous?

Norway rats are more than a nuisance—they pose serious health and safety risks. They’re known carriers of diseases such as leptospirosis, salmonella, and hantavirus. Additionally, their constant gnawing can compromise the integrity of electrical wiring, creating fire hazards, and damage insulation or piping.

When it comes to your well-being and that of your family or employees, there’s no room for delay in dealing with a Norway rat infestation.
