Muskrats are mostly nocturnal and remain active all year. They are not great travellers, and the average home range is no larger than a 200-yard circle in optimal habitat. It is during these crisis periods that muskrats are often seen on roads and travelling through urban subdivisions. At these times it is not uncommon to see a muskrat miles from the nearest source of water. Muskrats are eaten by a host of predators, including hawks, owls, raccoons, mink, fox, coyote and even largemouth bass and snapping turtles.
Muskrats also prey upon other muskrats.
During periods of overcrowding, other muskrats may kill entire muskrat litters. During a drought year, when overcrowding problems are magnified, muskrats are particularly susceptible to being eaten by other muskrats and a variety of other wildlife species. Muskrats are also susceptible to such diseases as tularemia and hemorrhagic disease, which can devastate an entire population. If you are experiencing muskrat damage to the point where lethal control is necessary, consider using control methods during the winter. Muskrat pelts are in their best condition at this time of year, and the pelts may be sold to local furbuyers if you possess a valid Kentucky hunting and trapping permit.
