At first glance, rats and muskrats may seem alike due to their similar rodent-like features, but they are vastly different in terms of habitat, behavior, and impact on the environment. While rats are common urban rodents that thrive in human settlements, muskrats are semi-aquatic creatures that play a role in wetland ecosystems.
This article will help you distinguish between rats and muskrats, covering their physical traits, behaviors, habitats, and potential risks.
Rats are notorious for invading homes, sewers, and storage areas. They thrive in dark, damp spaces and are excellent climbers, often accessing rooftops and attics. Their rapid breeding and ability to gnaw through materials make them a difficult pest to control.
Muskrats live in marshes, lakes, and riverbanks, where they build burrows or lodges with underwater entrances. Their presence is usually harmless unless their burrowing activity damages human-made structures like dams and levees.

What is a Rat?
Rats are highly adaptable rodents found in urban and rural environments. They are known for their survival instincts, ability to reproduce quickly, and tendency to infest homes and buildings. Their scavenging nature makes them a major nuisance in human settlements.Physical Characteristics of Rats
-
Size: Typically 6 to 9 inches long, excluding the tail, which adds another 7 to 9 inches. -
Shape: Slender, cylindrical body that allows them to squeeze through tight spaces.
-
Color: Usually brown, gray, or black with a lighter underbelly.
-
Tail: Long, thin, scaly, and hairless, used for balance and temperature regulation.

What is a Muskrat?
Muskrats are semi-aquatic rodents commonly found in wetland environments. Unlike rats, they are not urban pests but rather play a significant role in wetland ecosystems by controlling plant growth and creating habitats for other species.Physical Characteristics of Muskrats
-
Size: Larger than rats, measuring 16 to 24 inches long, including their tail.
-
Shape: Stocky and robust body with webbed hind feet for swimming.
-
Color: Typically brown with a lighter underbelly, covered in thick, waterproof fur.
-
Tail: Long, thick, and flattened vertically, which aids in swimming.

Rats vs Muskrats: Key Differences
| Feature | Rat | Muskrat |
|---|---|---|
| Size | 6 to 9 inches (excluding tail) | 16 to 24 inches (including tail) |
| Shape | Slender, cylindrical body | Stocky, robust body with webbed feet |
| Tail | Long, thin, scaly | Thick, flattened, and used for swimming |
| Habitat | Urban areas, sewers, basements | Wetlands, marshes, lakes, riverbanks |
| Diet | Omnivorous—scavenges food waste | Herbivorous—feeds on aquatic plants |
| Behavior | Nocturnal, social, highly adaptable | Semi-aquatic, solitary, prefers water |
| Health Risks | Spreads diseases, contaminates food | Can carry diseases, but less of a threat to humans |
Health Risks of Rats and Muskrats
While both rats and muskrats can pose health risks, rats are generally more dangerous to humans due to their association with urban environments.Health Risks from Rats
-
Disease Transmission: Rats spread serious diseases such as hantavirus, salmonella, leptospirosis, and rat-bite fever.
-
Food Contamination: Their scavenging habits make them a major cause of foodborne illnesses.
-
Parasites: Rats carry fleas, mites, and ticks that can further spread infections.
Health Risks from Muskrats
-
Disease Transmission: Muskrats may carry tularemia and leptospirosis, which can be transmitted through contact with their urine or contaminated water.
-
Environmental Contamination: Their burrowing can weaken waterbanks and cause flooding, leading to indirect hazards.
How to Prevent Rats and Muskrats from Entering Your Home?
Prevention is the best method for keeping rats and muskrats away from your property. Here’s how you can manage each pest effectively:Rat Prevention Tips
-
Seal Entry Points: Block all small gaps and cracks in walls, doors, and foundations, as rats can squeeze through openings as small as a quarter.
-
Eliminate Food Sources: Keep the food covered using airtight containers and wipe off any crumbs and spills regularly.
-
Reduce Clutter: Clear out storage areas and piles of debris where rats may nest.
-
Set Traps and Baits: Use traps strategically in areas where rats are commonly spotted.
Muskrat Prevention Tips
-
Water Management: Prevent standing water near your home and ensure proper drainage in your yard.
-
Habitat Control: Trim vegetation near water sources to reduce muskrat nesting sites.
-
Burrow Sealing: If muskrats are burrowing near your property, consult wildlife control experts to humanely remove them.
-
Fencing: Install wire mesh or barriers along water banks to deter muskrat activity.
Myths and Facts About Rats and Muskrats
| Myth | Fact |
|---|---|
| Muskrats are just large rats. | Muskrats are larger, semi-aquatic rodents, not large rats. |

| All rodents with long tails are the same. | Muskrats have short, flattened tails; rats have long, thin tails. |
| Rats and muskrats are both harmful to crops. | Muskrats are herbivorous and primarily affect aquatic plants, not crops. |
