The Deadliest Animals Found In Each US State

Every state in the US has its pros and cons. Even though the positive aspects of each state many times outweigh the negative ones, they are still worth examining before leaving your house. In this case, each state consists of wildlife that has been life-threatening to residents and tourists for several years.

From grizzly bears to tiger sharks, here we will reveal which animals to avoid in each part of the country.

Dogs in Alabama

To everyone’s surprise, in Alabama, dogs are not just man’s best friend, they are also man’s worst nightmare. According to the CDC, dog attacks are the primary cause of animal-related deaths in the state.

Even though untrained dogs tend to be more aggressive, it’s important to know what kind of animal we are putting inside our houses.

So, when visiting Alabama watch out with the canines, looks can be deceiving!

Moose in Alaska

Apart from being the largest state in the US, Alaska is also known for its untamable wilderness and huge populations of bears. Shockingly, bears are not the only creature that we should be worried about in Alaska.

The giant and intimidating Moose is the major cause of fatalities among humans in the state. That’s because these giant creatures regularly get hit by cars when crossing the highways and sometimes these crashes can be fatal.

Therefore, be careful when driving on these highways, there could always be a moose on the loose.

Dogs in Arizona 

When we think of Arizona, we think of its sun-drenched desert landscape, cacti, national parks, etc.

Yet, we rarely think of the things that could threaten us when we are there. And to our surprise, dogs are one of them. There have been 26 deaths in Arizona between the late 90s and 2000s.

There’s even a strict liability law in the state when it comes to dog bites. So, watch out! Petting a dog in Arizona could be life-threatening.

Black Bears in Arkansas

Although they are not the biggest bears in the wild, Black bears are something to be aware of in Arkansas. While most of these predators live secluded from human activity, experts say that their population has been increasing.

On one hand, that could signify a revival of wildlife in Arkansas, yet it could also affect the safety of livestock and humans.

Occasional injuries between humans and bears have been recorded in the state. And these injuries must have been unbearable (pun intended).

Rattlesnakes in California 

It’s certainly not all sunshine, and rainbows in California. Especially when coming across one of the most venomous snakes out there, the rattlesnake.

California Department of Fish and Wildlife

They’re quite a common sight in the Golden State but luckily many people survive to tell the story. To be more precise, the California Poison Control Center reported that there are about 800 rattlesnake bites per year, with only 1 to 2 deaths registered.

But don’t count on those statistics, when getting bitten by one of these slithering creatures it’s important to rush to the hospital.

Cougars in Colorado

When adventuring into the Colorado wilderness, it’s important to be careful not only with spiders and snakes but mostly with cougars.

Also known as mountain lions, these massive felines thrive in the isolated mountain ranges of the Centennial State.

However, according to reports, there has been 24 known attack of mountain lion causing injury to a human since 1990 in this region of the country with 3 fatal incidents. Even though cougars are beautiful they can also be a menacing animal.

Bobcats in Connecticut 

In Connecticut, snow blizzards are not the only threat. When exploring the Constitution State it’s crucial to keep our eyes peeled for bobcats.


These felines are popularly known for hunting wild rabbits, squirrels, etc, and sometimes come face-to-face with humans.

Even though they are most interested in eating livestock, there still has been a couple of attacks registered in Connecticut. It’s best to stay away from them even though they look like docile creatures.

Coyotes in Delaware 

In the small state of Delaware, cayotes are the one invasive species that the locals fear the most. They certainly are fearless and there are more attacks on human pets registered than in humans.

Regardless of that, as the population of these canines grows, the interaction between humans and coyotes becomes more common.

With that in mind, these animals are increasingly accustomed to people, and that poses a greater threat to both humans and their beloved pets.

Mosquitoes in Florida

In the sunny state of Florida, who would’ve thought that in a place with possibly the biggest alligators in the country, mosquitoes would be the deadliest threat to humans?


That’s because the Sunshine State has the perfect climate for these insects to reproduce and carry lethal diseases like dengue, West Nile, etc.

Make sure to bring loads of repellent when in this part of the country, because a little mosquito bite can turn into a huge problem!

Snakes in Georgia 

Amongst all the predators in the wild, snakes are probably one of the scariest ones and in Georgia, there we can find a variety of them.

The most common snakes found there are copperhead, cottonmouth, and coral snake which are also one of the most poisonous.

A single bite could take any of us directly to the ICU. Experts say the bite itself doesn’t hurt much but the poison released in our bodies could cause serious harm. When in Georgia, turn your snake alert on!

Tiger Sharks in Hawaii

On the beautiful island of Hawaii, there’s a fearful apex predator that lurks beneath the water: Galeocerdo cuvier, or the tiger shark.


Perhaps one of the most aggressive sharks, the tiger shark is a force to be reckoned with. And after a series of attacks in the state, residents claim that they have been spotted swimming extremely close to shores.

Experts say that there’s been an increase in tiger shark sightings especially after heavy rains when upland fishes and other animals are swept out to sea. So, testing the waters is of extreme importance when going for a swim in the ocean of Aloha State.

Bears in Idaho

When doing any outdoor activity, crossing paths with a grizzly bear is surely the last thing we would want to happen.

And when in Idaho we got to be wary of exactly that. These large mammals have been listed by CDC as the deadliest animals to come into contact with.

Weighing up to 600 pounds or more and with the ability to run at a whopping 30 mph, there is a reason why they are top-of-chain predators. So, be certain to carry bear spray at all times when exploring the outdoors of the Gem State.

Zombie Coyotes in Illinois 

At night in Illinois, just like in a horror film, streets get filled with Zombie coyotes. By zombies coyotes, we mean coyotes that have been infected with rabies.

Thanks to the infection, coyotes look like sick abandoned dogs and that’s where the danger lies. They are found in suburbs and residential areas where they know humans live.

Due to their unhealthy dog-like appearance, the nice Illinoisan people reach out to help but end up getting bitten by the aggressive canines. Hopefully, this is not the beginning of a zombie apocalypse.

Deer in Indiana 

Deers can be found all over America and especially in Indiana. But these docile animals pose a certain threat to all drivers in Indiana.

Unfortunately, these ruminant mammals are not the brightest, and in Hosier State, they cause numerous vehicle accidents.

In fact, in 2016, there were about 14,000 deer that were involved in car accidents in Indiana, which in some cases ended up costing the lives of these drivers. This makes us wonder if the deers in Indiana are even less intelligent than the average deer.

Cows in Iowa

Cows are mostly known for being sleepy, grass-eating animals. However, in Iowa, they have a different reputation.

Jeff McIntosh/The Canadian Press

This state has totaled 3.85 million heads of cattle and calves with about 28,000 cattle operations happening across the state. Being trapped in an enclosed space with an animal this size can be a risky activity, therefore, a lot of work incidents and sometimes fatal injuries take place in these scenarios.

With so many operations happening in Iowa, many livestock handlers, become a victim to these large cloven-hooved herbivores.

Cows in Kansas 

In the wild, cows behave much differently than in an enclosed space like a farm, or a feeding operation. They can become aggressive.

Local World

In Kansas, with so many operations going on daily, putting workers in such dangerous proximity to these animals result in many work-related accidents.

While some of them live to tell the story and work another day, others don’t. That’s to say that in the Sunflower State, cows are certainly the most dangerous animals.

Black Bears in Kentucky 

Although black bears look like cute and huggable animals but do not be mistaken. These wild mammals could take any of us out in a blink of an eye.

In Kentucky, the number of black bears seems to be increasing yearly. As their population gets bigger, interaction with humans becomes more common.

As we can imagine, this interaction is rarely positive for humans, and there have been several bear attacks reported in the state. So, be aware of the Kentucky bear.

Hornets in Louisiana 

Known for housing one of the biggest stinging insects, Louisiana is home to thousands of scary-looking hornets. As if the state’s large alligator population wasn’t frightening enough!

A hornet’s sting is not only more powerful than a bee’s but it can also sting multiple times. In the state, swarms of Asian hornets have attacked people several times and it’s the cause of most insect-related incidents.

Even though Louisiana Hornets may sound like a school mascot, they pose a major threat to any of us who finds ourselves there.

Moose in Maine

Known to be highly protective and territorial animals, in Maine, Moose are spotted quite frequently. In the rural areas of the state, they also present danger.

Even though these large animals don’t usually attack humans they have been responsible for 294 car collisions in 2021 alone.

Experts say that the collision numbers have been increasing each year and so is the Moose population in the area. As a result, driving in Maine can be a risky thing to do.

Bees And Other Stinging Insects in Maryland

In Maryland, bees and other stinging insects are a force to reckon with. Their painful stings and potential for severe allergic reactions, especially for those allergic to their venom are something to watch out for.

They can also become aggressive when threatened, increasing the risk of multiple stings.

Although it’s difficult to avoid these flying insects, it’s crucial to exercise caution and avoid encounters to minimize the danger.

Deers in Minnesota 

Different than other states, in Minnesota we don’t have to worry about venomous insects, snakes, or any of that. We have to be careful with the deer, primarily during the mating season!
