So what is the best way to get rid of nutria in your river banks? Herbivores, these animals feed on important wetland grasses and have wipe out hundreds of thousands of acres of protected wetlands in the south. Riprapping areas with stone creates an effective barrier and protect slopes from wave action. Another popular term, “beaver fever,” may be a misnomer.

The technical name for this illness is “giardiasis.” It is more commonly referred to as “giardia”—derived from giardia, the single-cell protozoa that causes the disease. If it is ok for you to trap and transport the nutria in your community, then the best thing to do would be to use traps. Because they are an animal used for its fur there may be regulations on them or you may get paid for ‘harvesting' them. Nutria damage is related to burrowing and feeding. Traps must be gotten according to the size and the number of nutria that you are trying to catch.

Some states protect these animals because of their status as furbearing. Since the wire will eventually corrode, do not use this material where people are likely to swim. Depending on the actual size of the nutria they may not even be deterred by dogs and traps may not be easy to find if at all. Do not release them without checking with your local laws as they are a severe pest in most areas with a population. Tularemia is fatal to animals and is transmitted to them by ticks, biting flies, and via contaminated water. It has never been demonstrated that the type of giardia beavers carry causes giardiasis in humans. Their hind legs are much larger than the forelegs. Aside from trapping, shooting is considered an acceptable method of nutria control.
Contouring your banks to prevent burrows is also an option, but again, this will require the use of heavy machinery which may not be able to reach the problem habitats. Nutrias do not breed as abundantly as many other rodents.

The traps are humane and depending on what you will be doing with the nutria you may decide to humanely dispose of them as well. The first thing to remember is that nutrias are rodents and therefore they can get diseases which most rodents are exposed to. The reason for that fear is that the livestock will in some cases drink from the same water which is the habitat of the nutria. The best thing to do to get the nutria out is to do so by using traps. The nose and mouth of the nutria can be closed off while swimming underwater to prevent liquid intake. Nutria pelts aren't valuable -- only fetching about three dollars -- but the animal can weigh up to 20 pounds and make a hearty meal. Accessibility is a big component to successful nutria removal. They are not, however, as large as beavers, growing to be approximately fifteen pounds at three feet long. NUTRIA BIOLOGY AND INFORMATION: Shooting has been an effective in eliminating small isolated groups of nutria. Extreme care should be taken when handling captured nutria. Public Health Threat – Nutria are known to carry pathogens and parasites that can infect not only local Delta wildlife, livestock, and pets- but also humans. Next, fill the trench with a mudpack. Exposing their tunnels from above may also work. Similarly, dropping water levels during the summer will expose nutria dens to predators, forcing them to seek a more secure area. How To Get Rid Of Nutria In Your Yard

Typically dens have 2 feet or more of earth above them.

The coypu population in Louisiana alone was over two million at the height of the problem. (Lethal control can be effective in areas where the local population of nutria is still small.) When you look for traps it is important that you get the right size and bait. Nutrias are easily identified by a white patch of hair around their mouths as well as by their bright orange teeth. In the 1930s, they were sold throughout North America to fur farmers and as a means of controlling unwanted aquatic vegetation.

Originally introduced to California in the late 19th century as a non-native species to support the fur industry, nutria were reintroduced periodically up until the collapse of the fur industry in the 1940s. If you are planning to trap the nutria or to use any other removal methods you should first become familiar with the laws regarding nutria in your area. The hind legs are longer than the front and boast webbed digits for better mobilization in the water.


Their most notable feature is their orange incisors. When you look for traps it is important that you get the right size and bait. Some people have had success using old cat litter in this way. No special trapping permit is necessary for the use of live traps. Like other semi-aquatic animals, nutrias are often brown, and their fur was once highly sought after.

To extend the life of galvanized hardware cloth, spray it with automobile undercoat paint or other rustproof paint before installation. However, a special trapping permit is required for the use of all traps other than live traps (RCW 77.15.192, 77.15.194; WAC 220-417-040). This is nematode which causes “nutria rash” in people who handle the rodent.
