8 Ways to Keep Beavers Away from Your Trees Without Harming Them

Beavers: Ecosystem Engineers and Backyard PestsBeavers are well-known ecosystem engineers, creating wetlands that provide habitat for a wide range of plants and animals. They are nature’s architects, building lodges out of wood and mud along the banks of rivers and streams.

However, when they move into backyard areas, they can quickly become a nuisance, damaging trees and other vegetation. In this article, we’ll look at the importance of beavers in ecosystems, the problems they can cause in suburban areas, and ways to keep them away from trees.

Importance of Beavers in Ecosystems

Beavers are considered ecosystem engineers because they have a significant impact on the physical structure of the environment in which they live. By building dams, they create wetlands, which provide essential habitat for many species of plants and animals.

Wetlands act as natural filters, cleaning water and reducing the risk of flooding. In addition to their dams, beavers build lodges, which provide shelter for themselves and their families.

These lodges are made of mud and sticks and can be quite large, sometimes reaching 10 feet high and 20 feet wide. Inside, the beavers create a maze of tunnels and chambers, with a central living area that is protected from predators.

Beavers are also important seed dispersers. They consume a wide variety of plants, including woody species, and the seeds pass through their digestive system intact.

When they defecate, they spread these seeds throughout the wetlands, contributing to the diversity of plant species in the area.

Problem of Beavers Damaging Backyard Trees

While beavers are essential to the health of ecosystems, they can cause significant damage when they move into suburban areas. One of the most significant problems is the damage they can do to trees.

Beavers are particularly fond of aspen, cottonwood, and willow trees, but they will also eat fruit trees and other deciduous species. When a beaver decides to chew on a tree, it doesn’t take long for it to cause significant damage.

They use their sharp teeth to strip away the bark, which can kill the tree or at least weaken it enough to make it more susceptible to disease and rot.

Ways to Keep Beavers Away from Trees

If you live in an area where beavers are active, there are several ways to protect your trees from damage:

1. Fencing – One of the most effective ways to prevent beavers from damaging your trees is to erect a fence around them.

A wire fence extending at least 3 feet above ground and 1 foot below will keep beavers out. 2.

Painting Tree Trunks – Painting the trunks of your trees with sand and paint can make them less appealing to beavers. This makes it difficult for beavers to grip the bark and strip it away.

3. Deterrents – There are a variety of repellents available that are designed to keep beavers away from trees.

These include chemical deterrents and noise makers. Keep in mind that these deterrents may not be 100% effective and may need to be reapplied regularly.

4. Planting Trees Elsewhere – Finally, if you have a large number of beavers in your area and are tired of protecting your trees, you may want to consider planting them in a different location.

This will allow the beavers to continue to live in their natural habitat without causing damage to your property. Where Are the Beavers Even Coming From?

Beavers are found throughout North America and can be identified by their large, flat tails and webbed hind feet. Their preferred trees include aspen, cottonwood, and willow, but they will eat a variety of species depending on what is available.

Beavers are nocturnal animals and are most active at night. They are excellent swimmers and can remain underwater for up to 15 minutes.

In the wild, they live in lodges that are built along the banks of rivers and streams.


Beavers are essential to the health of ecosystems, creating wetlands that provide habitat for many species of plants and animals. However, when they move into suburban areas, they can cause significant damage to trees and other vegetation.

There are several ways to keep beavers away from trees, including fencing, deterrents, and painting tree trunks. If all else fails, consider planting trees in a different location.

Understanding the behavior and preferences of beavers can help reduce the potential for conflict and allow you to coexist with these fascinating creatures.

3) Simple Tips To Keep Beavers Off Your Trees Without Trapping

Beavers are incredible creatures that play critical roles in ecosystem dynamics. This includes keeping wetlands and streams healthy, providing habitat for various animals, and aiding in the spread of seeds.

However, when they invade yards, these same beavers can cause serious damage to trees, bushes, and other plants, ruining the outdoor environment. Even more troubling is that trapping them is often neither legal nor humane as it disrupts the natural balance.

Here are some simple, non-lethal ways to deal with beavers in your yard.

Importance of Preventing Beavers from Entering Yard

By keeping beavers away from your yard, you will avoid damage to your trees and other plants, preserve your property’s aesthetics, and minimize the expenses associated with repairing damages. Prevention also allows these animals to remain in their natural habitat without being unnecessarily subjected to harm or stress.

Using Fencing to Keep Beavers Away from Trees

Fencing is the easiest and most effective method of preventing beavers from entering your yard or reaching trees. Fencing works by creating a physical barrier that prevents beavers from swimming or wading into the yard.

Install it before any property damage occurs to discourage beavers from choosing your yard as their new destination.

Using Painting Mixture to Make Tree Bark Unpalatable to Beavers

Another way to protect your trees from beavers is by making them unappetizing. A common mixture that has worked wonders is by combining sand and paint and applying it to trees.

Rough and sandy-textured bark does not appeal to beavers, and the unpleasant taste may discourage them altogether.

Using Dogs or Predator Urine to Frighten Beavers

Beavers have natural predators in the wild, such as wolves and coyotes that hunt when beavers are active. As a result, the smell of dogs or predator urine is usually enough to frighten them off.

Some homeowners have had success with using dog hair clippings or sliced onions to mimic the scent of a predator. Placing this around the yard can help to deter beavers.

Using Motion-activated Sprinklers or Spray Solutions to Deter Beavers

Motion-activated sprinklers, such as the Scarecrow sprinkler, provide another non-lethal option. When the beaver approaches the sprinkler, it will be triggered, and it will shoot out a blast of water that can startle or frighten the animal.

Similarly, spraying a solution that contains ingredients that beavers find unpleasant on the tree trunks or around the yard can act as a repellent, keeping these animals away.

Planting Non-preferred Trees to Deter Beavers

Finally, if you have a significant amount of beaver activity in your area, one thing you can do is plant non-preferred trees. Beavers prefer certain trees, such as aspen, cottonwood, and willow, but they are not limited to just those species.

By planting other types of trees that are not palatable to beavers, you can make your yard less attractive to them.

4) Use Fencing To Keep Beavers Off Your Trees

Fencing is one of the most effective ways to keep beavers away from your trees. A sturdy fence will create a physical barrier that beavers cannot easily pass.

Here are some key things to pay attention to when installing your beaver-proof fence.

Types of Fencing to Use

The best fence type to use is welded-wire mesh fence renowned for its versatility and durability. A popular model is the 16-gauge galvanized welded wire mesh that is corrosion-resistant, long-lasting, and cost-effective.

The wire mesh must be tightly secured to metal posts for optimum strength and rigidity.

Proper Installation and Height of Fencing

Beavers are excellent climbers and can easily scale any fence that is not tall enough from the ground. The fence should be at least 4-feet high, and the bottom 18 inches of the fence should be buried underground to prevent beavers from digging underneath.

Ensure that the mesh has no holes that the beavers can enter through, including the wire crossing points. Bracing the posts with horizontal support rails and tension wire can further reinforce the strength of the fence.

Effects of Preventing Beavers’ Access to Trees

By keeping beavers from getting to your trees, you can preserve the aesthetics of your yard and protect the plants. This also helps to avoid safety risks that can occur when a tree damaged by beavers falls.

Additionally, preventing their access to trees will encourage them to search elsewhere for food, which will enable them to live in their natural environment without causing harm to your property.

In summary, preventing beavers from entering your yard is a critical step in protecting your trees, plants, and property in general.

Fencing, applying a painting mixture, using dogs or predator urine to scare them off, using motion-activated sprinklers, and planting non-preferred trees can all work together to achieve this. By using these techniques, you can peacefully coexist with beavers and let them continue to play their roles in preserving the health of ecosystem dynamics.

5) Protect Your Trees From Beavers By Using A Painting Mixture

One way to prevent beavers from damaging your trees is by using a simple painting mixture made from sand and paint. Beavers find the rough and gritty texture of sand on tree bark unappealing and will quickly move on to find other food sources.

Here’s how to make this mixture and make the most of it.

How Mixing Sand with Paint Repels Beavers

Beavers rely on the bark of trees as their primary food source. When they move into your yard, they will quickly begin to chew on the trees, causing significant damage and even death if not stopped.

By applying a sand and paint mixture to the bark and trunk of the trees, it makes it difficult for them to grip the bark and will ultimately make the tree unpalatable. Beaver will quickly learn that your trees are not a feasible food source and will move elsewhere.

Recommended Sand and Paint Types to Use

The recommended sand to use is coarse sand, ideally river sand, because beavers find it more cumbersome to deal with its rough texture. Mixing this with outdoor latex paint that is weather-resistant and environmentally friendly will create a repellent paint that is non-toxic and safe for use around family and pets.

For best results, mix the paint and sand in equal parts.

Benefits of Using Latex Paint

Latex paint has grown in popularity in recent years because it is less toxic and more environmentally friendly than other types of paint. It also dries quickly and is effortless to clean up after.

This type of paint will adhere well to the bark of the tree, producing a durable barrier that will last for a long time. Unlike oil-based paints, most latex paints do not contain harsh solvents that can harm or soften the bark on trees, making it an ideal type of paint to use when creating a repellent.

6) Your Dog Can Keep Beavers Off Your Trees

Dogs are excellent companions and are often referred to as “man’s best friend.” They are not only loyal but can also be trained in various ways, including being trained to help protect your trees from beavers. Here’s how they can help and how to use them effectively.

Studies Showing Dogs’ Effectiveness in Repelling Beavers

Several studies have shown that dogs are effective deterrents against beavers. One such study published in the International Journal of Zoology found that dogs are more effective at repelling beavers compared to other forms of repellents, such as noise makers, chemical traps, and scare devices.

Dogs are more effective as beaver deterrents because they simulate natural predators in the wild.

Methods for Using Dogs to Deter Beavers

When using dogs as a deterrent, it is essential to have proper training, so they don’t attack the beavers. The best approach is to train dogs as “beaver guardians” rather than “beaver hunters.” You can do this by exposing them to the scent of beavers and training them to alert you when they sense beavers are in the area.

Another way dogs can help is by keeping beavers away from the water’s edge, which can be a primary location where they build dams or lodges. You can do this by tethering dogs near the water’s edge or allowing them to roam freely in your yard.

Just ensure that the dogs are vaccinated and have the necessary permits if required by local laws.


Protecting your trees from beavers is essential, not only for the health of your trees but also to preserve your property’s aesthetic value. Using a painting mixture made of sand and paint, along with planting non-preferred trees, motion-activated sprinklers, and installing fences can all work together to prevent beaver damage.

Additionally, using dogs as a natural predator guard can be an effective way to keep beavers at bay and out of your yard.

7) Frighten the Beavers from Felling Your Trees

Beavers are intelligent animals, and it can be challenging to dissuade them from felling your trees. Apart from damming running water, felling trees forms a significant part of beaver behavior, and it is therefore imperative to keep them away from your trees to prevent any damage.

Fortunately, several frightening devices can be used to deter beavers from felling trees. Let’s take a closer look at them.

Frightening Devices to Use

Beavers tend to have an instinctive aversion to sudden movements and loud noises, and therefore, devices that spur shock can be used to deter them. Examples include motion sensor lights, noise makers, and various forms of distractions such as balloons, inflatable snakes, and scarecrow-like figures.

Sound tends to spread quicker in air, while vibrations travel through both air and water, making it ideal to use combination devices that emit noise and vibrations for two-sense stimulation.

Importance of Stimulating Two Senses

Beavers rely on their sense of hearing and touch through vibrations, which they utilize to assess threats and danger in their environment. Successful frightening devices should, therefore, create audible noise and vibrations that cause panic in beavers.

Noise alone may not be effective as beavers rely on ground vibrations to sense fear, while ground vibration without noise may not be effective if the beavers are accustomed to the area’s vibrations.

Effectiveness and Limitations of Frightening Devices

Most people who have used frightening devices report that they are effective in scaring away beavers, particularly if used immediately after the beavers start gnawing on the trees. However, its efficiency may not always be guaranteed as beavers can learn to overcome their fear of such devices.

Also, because they rely on two senses for threat detection, their effectiveness may be limited if placed too far or out of reach of the beavers.

8) Spray Solutions Around Your Trees to Keep Beavers Away

Another way to prevent beavers from felling your trees is by spraying scents or solutions that repel them. Several scents and solutions can be sprayed around your trees to keep beavers away.

Here are some of the most popular ones.

Scents and Solutions That Repel Beavers

Hot sauce, cayenne pepper, garlic, and other pungent smells can work effectively on beavers. This is because these solutions irritate the beaver’s sense of smell or taste, causing them to move on to other areas in search of food and shelter.

Human hair, urine, and predator scents, such as fox urine, have also been known to work as repellants. Effectiveness of Hot Sauce, Cayenne Pepper, and Garlic
