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.

Extra factsMuskrats build lodges of grass and reeds usually 2′ to 4′ high.
Muskrats are capable of breeding after one year, however, due to predators and habitat loss, many individuals don’t live past one year of age.


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. 


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