Beavers are not considered dangerous to humans, but caution should still be taken when encountering them. Beavers are known for their strong teeth and powerful jaws, which they use to fell trees and build dams. This can lead to damage to property and flooding in areas where beavers are present. However, if left undisturbed, beavers are generally peaceful animals that pose little threat to people. In rare cases, beavers may become aggressive if they feel threatened or cornered, so it is important to give them plenty of space and avoid disturbing their habitats.

Although beavers may look cute and harmless with their oversized front teeth, beady little eyes, and funny flat tails, they can be dangerous to humans and pets in certain situations. While beaver attacks are rare, they may occur, especially if the animal feels threatened. The most aggressive behavior beavers exhibit is slapping their paddle tail on the water to create a loud noise.
Beaver attacks may occur when the animal is sick with rabies, as happened in several incidents in the past few years, including a 2012 attack on two Virginia girls. However, beaver attacks generally make great headlines because they are incredibly rare.
Beavers are the largest rodents in North America, weighing between 35 and 65 pounds (16 and 30 kilograms). They are clumsy on land but graceful in water, able to swim at about 6 mph (10 kph). They spend their time building dams and lodges to protect themselves from predators and store food. They are not known for attacking humans.
What Are Beavers Really Like?
Beavers are found throughout North America, except in desert ecosystems. They are hardworking animals, cutting down trees, moving logs, and building various structures in ponds, creeks, and lakes. Their long incisors continuously grow throughout their lives, which are filled with iron, making them stronger than those of other animals like rats. The iron teeth allow the beaver to cut through trees.

According to Callahan, beavers are herbivores and do not eat fish or other creatures. They are cared for by their parents until the age of 2, after which they find lifelong mates and build lodges for long-term homes. Beavers are known for modifying their environments by adding sticks, branches, and mud to their dams.
Beavers are a “keystone species” in North America, meaning their presence increases biodiversity. Their dams turn streams into ponds, creating new habitats that support various plant, insect, fish, and animal species, including endangered ones. Beavers also help fight climate change and wildfires, store water, improve water quality, and restore watersheds. However, their activity sometimes causes conflicts with humans.
Historically, humans have had a significant impact on beavers and their habitats. Fur traders nearly drove them into extinction to make hats, coats, and clothing. With modern regulations, beaver populations have rebounded, with roughly 6 to 12 million in the United States alone.
Beavers are known for their ability to transform the landscape to suit their needs, second only to humans. With careful management, their populations should remain safe for decades to come, and conflicts with humans will remain isolated to a few scattered flooding problems.
Fun fact: Native Americans referred to beavers as “Little People” because of their ability to transform the landscape.
FAQ
1. What kind of dangers do beavers pose?
Beavers themselves are generally not considered dangerous to humans. However, they can cause property damage by building dams and flooding areas. Additionally, beavers have been known to carry diseases such as giardia and leptospirosis, which can be transmitted to humans through contact with their urine or feces.
2. Can beavers attack humans?
It is extremely rare for beavers to attack humans. They are typically shy and will avoid contact with people if possible. However, if a beaver feels threatened or cornered, it may bite or lash out with its powerful tail. It is important to give beavers plenty of space and avoid disturbing their habitats.
3. What should I do if I encounter a beaver?
If you come across a beaver in the wild, it is best to observe it from a safe distance and avoid disturbing its habitat. Beavers are generally not aggressive towards humans, but they may become defensive if they feel threatened. If you need to pass by a beaver dam or lodge, give the animal plenty of space and avoid making sudden movements or loud noises.
4. Are beavers a threat to pets?
Beavers are not typically a threat to pets such as dogs or cats. However, pets should still be kept away from beaver lodges and dams, as these structures can be dangerous and unstable. Additionally, beavers may view pets as a potential threat and become defensive if they feel their territory is being invaded.
5. How do beavers impact the environment?
Beavers are considered a keystone species in many ecosystems. Their dam-building activities can create wetland habitats that support a wide variety of plant and animal species. However, beavers can also cause environmental damage in certain situations. For example, if a beaver dam is built in an area that is already prone to flooding, it can exacerbate the problem and lead to property damage.
6. Can beaver dams be removed?
While beaver dams can be frustrating for property owners, it is important to remember that these structures play an important role in the ecosystem. If a beaver dam is causing significant property damage or posing a safety hazard, it may be necessary to remove it. However, this should only be done as a last resort. In most cases, it is possible to work with a wildlife management professional to find alternative solutions that allow the beavers to remain in the area.
7. Is it legal to hunt beavers?
In many areas, beavers are considered a game animal and can be legally hunted during designated hunting seasons. However, there are also laws in place to protect beavers and their habitats. It is important to check local regulations and obtain the necessary permits before hunting or trapping beavers. In some cases, it may also be necessary to consult with a wildlife management professional to ensure that the beaver population remains healthy and sustainable.
