Muskrat

Muskrats are small aquatic rodents often found in ponds, drainage ditches, and shoreline areas. Though smaller than beavers, they can cause significant damage by burrowing into banks, dams, and shorelines. Most wildlife control calls involving muskrats relate to collapsing banks, leaking ponds, or structural weakening near water features.

When to Call a Professional

If you notice holes, sinking ground near water, or unexplained pond drainage, muskrats may be responsible and should be addressed quickly.

Identification
Tips

Medium-small brown rodent
Long, narrow tail (not flat like a beaver’s)
Small ears and blunt snout
Usually seen swimming
They are active year-round and often most visible at dawn or dusk.

Biology and Life Cycle

Lifespan: 3–5 years
Breeding: Spring through summer
Young: 4–8 per litter
Habitat: Marshes, ponds, lakes, slow streams
Muskrats create underwater burrows with entrances below the surface.

Behavior and Habits

Muskrats are strong swimmers and excellent diggers. They excavate tunnels into pond banks or embankments to create nesting chambers above the waterline.

Signs of Muskrat Activity

Holes in pond banks or shoreline edges
Burrow openings near water level
Mud trails or feeding platforms
Aquatic vegetation cut near shore

Risks and Health Concerns

Erosion and bank collapse
Dam or levee failure
Water loss from ponds
Structural weakening of shorelines

Removal and Control Techniques

Professional muskrat control often involves trapping, habitat assessment, and reinforcement of damaged banks. Addressing burrow systems is essential to prevent recurring issues.
