Muskrats are usually found living in and around marshes, streams, ponds, and lakes. They will dig burrows into the edge of the banks or they may create a burrow inside of thick vegetation located in shallow waters. The extensive burrows and tunnels that they create is what makes them such a dangerous pest. They will damage and destroy shore lines, rice and other crops, boat docks, marinas, and dams.
Muskrats are omnivores, but mainly feed on vegetation. Aquatic plants, cattails, grasses, field crops (rice), fish, frogs, and snails are all common sources of food for them.
