How to Get Rid of Invasive Nutria?

Rodents in the yard or on the property can be a big nuisance. They can spread diseases, wreak havoc on the property, and may contaminate the food.

Nutrias are such rodents, and no property owner wants them anywhere near them.

So, if you are experiencing a problem with Nutrias on your property, then here is a complete guide for you.

Through this article, I will help you understand how you can effectively get rid of these rodents forever. What tools can you use to stop them, and should you kill them for good? Let’s begin.

What are Nutria Rats?

Before we learn about the various ways of controlling them, we first need to understand what they are.

Nutria rats (also called coypu, river rats, and giant swamp rats) are incredibly large rodents that are native to South America.

In fact, they are one of the largest known living rodents in the world that can grow as big as 28 to 42 inches in length. Plus, they can weigh more than thirty pounds when they grow up to be adults.

The most distinctive features of nutrias are their long reddish-orange teeth and even longer whiskers on their face.

They were brought to North America because their fur was valuable, and there was a high demand for it.

However, during the 40s, their fur lost its importance, and they transformed into an invasive species.

The Nutria rats began to be a nuisance and caused damage to wetlands, vegetation, and many crops. That is because they dig deep, live in burrows, and only eat vegetation.

Different Ways to Get Rid of Nutria Rats

Now that you know all about Nutria rats, it is time to understand how you can get rid of them.

Here are many effective ways you can utilize:

1. Setting Traps

Setting traps is the most effective way to get rid of Nutria rats.

However, setting a trap may be challenging as it requires a lot of time and patience if the population of Nutria rats is high in the area.

There are many different traps you can utilize to catch Nutria rats.

Some of these you can use include:

• A leg hold trap
• A live double door trap

Both of these are the most effective traps when it comes to catching Nutria rats.

Remember that you need to keep a check on these traps every day and maintain them so that you can dispose of the Nutria rats soon enough.

2. Snares

As an alternative, you can even consider snare sets that involve wire cables and mounting loops.

However, they can be tricky to use, so make sure you use them if only you know how to use snares for catching nutria.

Plus, the animal can get nasty when snared, so you must also deal with them carefully.

3. Releasing Predators

If you have a large population of Nutria rats on your property, you need to release their predators into the ecosystem.

The most effective way to rid of them is to release two to three garter snakes on the property, and they will end up feeding on all the Nutria rats.

Once the snakes have eaten the Nutria rats and there are no more to feed on, they will leave.

So, if you are not afraid of snakes on your property, this is one of the most effective ways.

How Do Nutria Rats Impact the Ecosystem?

Nutrias were not part of the natural ecosystem.

They were introduced unnaturally, and that’s why they are considered a pest.

They invade the property and cause a lot of nuisance. Their diet is vegetarian as they consume wheat, alfalfa, sawgrass, cattails, rice, and many more.

While this is not a problem for normal homeowners, it is a big problem for farmers and gardeners.

Most farmers and gardeners rely on the crops as their source of income, and Nutria rats can easily destroy them.

However, they are an even bigger nuisance for water banks and dams. They dwell in dams and make their burrows in water banks.

If their population keeps growing in these dwellings, they can disrupt the flow of a dam and they can destroy a water bank.

So, in conclusion, their effect on the ecosystem is significantly negative, and that’s why they need to be controlled.

What Kills Nutria Rats – Should You Poison Them?

Many people wonder whether common rat poison can be used to kill Nutria, sometimes called nutria rats.

While standard rodent poisons may appear to be a simple solution, using them against nutria is generally not recommended and may even be illegal in many areas.

Nutria are much larger than typical rats, so common household rat poisons are often ineffective or require large amounts to work.

More importantly, poison can create serious risks for pets, livestock, birds, and other wildlife that might accidentally consume the bait. Even predators or scavengers that eat a poisoned nutria can be harmed.

Another issue is that poisoned nutria may crawl into burrows, dense vegetation, or water before dying. This can make removal difficult and may create unpleasant odors or sanitation problems.

Because of these concerns, wildlife experts usually recommend safer and more controlled methods for managing nutria populations.

These include heavy fencing around gardens, habitat modification, and the use of properly designed cage traps placed along nutria travel paths near water.

In areas with large infestations, contacting local wildlife authorities or professional pest control services is often the safest and most effective way to deal with nutria without putting other animals at risk.

How to Inspect and Look for Nutrias on Your Property?

Controlling and stopping the nutria from coming to your property is just one aspect.

Before you can do that, you need to inspect where the Nutrias are hiding and if they are even there on the property.

The first thing you should do is search your property inside out.

The starting point of your search should be next to bodies of water. That is because Nutria rats love to inhabit places that are close to sources of water.

You can search for them in:

• Fields
• Crops
• Yard
• Garden
• Crawl spaces
• Water-retaining levees
• Marshes

You need to look for various factors that indicate a Nutria rat is habituating nearby in these places.

Signs of nutria

Of course, there are many signs you should be on the lookout for when tracking nutria. But the biggest sign you should look for is their burrows, slides, and trails.

These will be filled with Nutrias tracks, and you will be able to know that they are lurking nearby.

The tracks of Nutria rats look like four webbed toes with one toe on the side that isn’t webbed. That is what their hind foot looks like, so these are small signs you should look for.

Besides that, Nutria rats leave their droppings wherever they are dwelling.

These droppings are black or dark green, are cylindrical, have a length of two inches, and have a diameter of half an inch. If they are dwelling on your property, you will find these droppings everywhere.

Additionally, if there are trees on your property, then the Nutria rats may be feeding on them. You can easily tell this as the tree’s bark will be peeled if Nutria has fed on it.

How Do You Tell the Difference Between a Beaver and a Nutria?

Many people confuse a Nutria with a Beaver because both are large, semi-aquatic rodents that live near water. At first glance, they may look similar, but there are several clear differences in their appearance, behavior, and diet.

Like many rodents, nutria are highly attracted to vegetable gardens and agricultural crops. In the wild, they feed heavily on aquatic plants, but their diet is not limited to that.

Nutria will also eat mussels, bird eggs, and a wide variety of crops such as rice, corn, wheat, barley, oats, peanuts, alfalfa, and sugarcane.

They may even gnaw on tree bark and roots when other food sources are scarce. Because of their strong appetite and ability to reproduce quickly, nutria are often considered destructive pests in wetlands and farmland.

Another reason nutria are often misidentified is their appearance. At a distance, they can be mistaken for several other animals, including wild pigs, raccoons, or even beavers.

Their brown fur and stocky bodies make them look similar to these animals when seen near water or moving through vegetation.

However, nutria, beavers and muskrats are very different animals. Beavers are larger and are best known for their broad, flat tails and their ability to build dams and lodges.

Nutria, on the other hand, have long, round, rat-like tails and do not build large dams. They also have distinctive orange front teeth that are easy to notice up close.

In short, while nutria and beavers may share similar habitats, their physical features, behaviors, and ecological roles make them clearly different animals.

Does nutria make good pets?

Although not very common, many people agree that coypu or nutria rats can be kept as good pets.

However, before you think of keeping them as pets, keep in mind that nutria is an animal that can get aggressive, bite, scratch, and even cause serious damage.

Especially they can be dangerous to other pets like dogs as they are known to be territorial and can do whatever to defend themselves.

Is the nutria the largest rodent in the world?

No, the Capybara is the biggest living rodent on Earth. They are semi-aquatic and can be found throughout northern and central South America. A small invasive population has also been seen in Florida.

Few other large size rodents that are known to live on earth include:

• Castoroides
• Giant Hutia
• Josephoartigasia
• Bosavi Woolly Rats
• Swedish Viking Rats
• The Gough Island House Mouse

What are the most effective tools that would stop nutria?

The most effective tools to stop Nutria include strong fencing, live traps, and habitat control.

Heavy-gauge wire or hardware cloth fencing buried 12–18 inches into the ground can prevent them from digging under gardens or ponds.

Live or cage traps placed along travel paths are also commonly used to capture them.

Motion-activated lights or sprinklers can help scare them away. In areas with serious infestations, professional wildlife control or regulated trapping programs may be necessary to manage nutria populations effectively.

Final Words

Dealing with Nutria can be frustrating, especially if they are damaging gardens, crops, or pond banks.

While it may be tempting to use quick solutions like poison, these methods often create bigger problems for pets, wildlife, and the surrounding environment.

A better approach is to focus on prevention and responsible control methods such as fencing, trapping, and removing food sources that attract nutria in the first place. These methods are safer, more reliable, and help protect other animals in the area.

With the right strategy, you can effectively manage nutria problems and keep your property protected without causing unintended harm to the ecosystem.
