Sewer rats, known scientifically as Rattus norvegicus or the Norway rat, are one of the most notorious and widespread pests. Often associated with urban legends and unsavory environments, these rodents are more than just a creepy encounter—they’re a significant health hazard. At Killian Pest Control, we understand that identifying sewer rats is the first step toward keeping your home and business safe. In this guide, we’ll explore what makes these rodents unique, how to spot their presence, and the best ways to address an infestation.
What Is A Sewer Rat?
Sewer rats are large, burly rodents that thrive in environments rich in food waste, moisture, and shelter. Unlike their smaller cousins, the black rat (Rattus rattus), sewer rats are ground-dwellers that often infiltrate basements, sewers, and low-lying areas.
Characteristics Of Sewer Rats
- Size: Adults range from 7 to 9.5 inches in body length, with a tail almost as long as their body.
- Weight: They can weigh up to 1 pound.
- Color: Typically brown or gray with a paler underside.
- Appearance: A blunt nose, small ears, and a thick, scaly tail distinguish them from other rats.
Despite their unsavory reputation, sewer rats are incredibly resourceful and adaptable. Their survival skills allow them to inhabit a variety of settings, from urban sewer systems to rural farms.
Why Are Sewer Rats Dangerous?
Sewer rats are more than a nuisance—they’re a public health concern. These rodents are carriers of several diseases that can harm humans and pets. They contaminate food, spread pathogens, and cause significant property damage.
Common Health Risks
- Leptospirosis: Spread through their urine, this bacterial infection can lead to severe kidney or liver damage.
- Hantavirus: Exposure to their droppings or urine can result in respiratory infections.
- Salmonella: Sewer rats contaminate food and surfaces, leading to food poisoning.
- Rat-bite Fever: This disease spreads through bites or scratches.
In addition to health risks, sewer rats can gnaw through walls, wires, and even plumbing systems, creating costly damage.
How To Identify A Sewer Rat Infestation
Knowing how to spot the signs of a sewer rat infestation can save you time, money, and stress. Sewer rats are nocturnal creatures, meaning they are most active at night. Here’s what to look for:
1. Droppings
Sewer rat droppings are a clear indicator of their presence.
- Shape and Size: Capsule-shaped and roughly ¾ inch long.
- Location: Found near food sources, along walls, or in hidden spaces like basements and attics.
2. Gnaw Marks
Rats need to constantly gnaw to keep their teeth from overgrowing.
- Surfaces: Wooden furniture, electrical wires, and plastic piping.
- Pattern: Look for rough, chewed edges.
3. Footprints And Tail Marks
In dusty areas, you may notice their footprints or tail drag marks. Use a flashlight to inspect dark corners for these subtle signs.
4. Burrows And Nests
Sewer rats build burrows to create nests for shelter.
- Common Locations: Near foundations, under porches, and around sewer lines.
- Appearance: Small openings in the ground with well-worn paths leading to them.
5. Sounds And Smells
- Sounds: Scurrying noises or squeaks, especially at night.
- Smell: A musky, pungent odor can indicate a significant infestation. Visit Effective Rodent Control: What Smells Do Mice Hate? to learn more.
Why Sewer Rats Love Urban Areas
Urban areas are a paradise for sewer rats. The combination of accessible food, water, and shelter makes cities ideal for their survival. Here’s why they thrive in these settings:
- Sewers as Highways: Sewer systems offer an extensive, hidden network for rats to travel and breed.
- Food Availability: Trash cans, dumpsters, and food scraps provide a constant buffet.
- Shelter: Buildings, abandoned structures, and underground spaces are perfect nesting grounds.
At Killian Pest Control, we’ve seen firsthand how sewer rats exploit urban environments. They can squeeze through gaps as small as half an inch, making it easy for them to infiltrate homes and businesses.
Misconceptions About Sewer Rats
Sewer rats are often misunderstood. Here are some myths and the truth behind them:
Myth 1: Rats Only Live In Dirty Places
Fact: While sewer rats are often found in sewers, they can inhabit clean homes if there’s food and shelter.
Myth 2: Rats Are Solitary Creatures
Fact: Sewer rats are highly social and live in colonies. A single sighting could indicate many more are nearby.
Myth 3: Cats And Dogs Can Eliminate Rats
Fact: While pets may deter some rats, a full-blown infestation requires professional intervention.
