Muskrats

Muskrats are a type of rodent and they are related to mice, voles, beavers, and rats. They are the most abundant furbearer in the United States. The name muskrat comes from both its strong smelling scent and it’s rat-like appearance. Muskrats have an average lifespan of less than a year and they do not hibernate.

Complaints

Muskrats are known for burrowing into pond and stream banks and slowly eroding away those banks. They are herbivores and will eat grasses and flowers near the water’s edge. 

Solutions

Muskrats can be trapped with foothold and body-gripping style traps. Reinforcing pond and stream banks with wire mesh will sometimes alleviate the problem.
