Did you know the density of dangerous animals in Wisconsin is among the highest in the nation? It’s true. However, it’s not just bears and wolves that are lurking in the woods. Turns out, predators in Wisconsin come in all shapes and sizes in the Badger State. Take a look:
- White-Tailed Deer

- Ticks

And though tiny, ticks are mighty frightening, as they spread a slew of life-threatening and chronic diseases, including Lyme disease, which is currently the most common tick-borne illness in Wisconsin. What’s more, tick-related diseases caused at least 10 deaths between 2015 and 2018.
- Mosquitoes
Tom/Flickr Not just a nuisance, mosquitoes can transmit a myriad of diseases, including the West Nile virus, which, in 2017, caused the deaths of four Wisconsinites. The pesky insects also spread La Crosse encephalitis. Though most show no symptoms, severe cases can include seizures, coma, and paralysis.
- Bears
djvass/Flickr No list of dangerous animals would be complete without bears, which are among the state’s largest wild predators. However, as it turns out, the likelihood of being attacked or killed by a bear in Wisconsin is extremely low. In fact, the last recorded “bear attack” was in 2017 in Florence County. The USDA states that most bear attacks in the state are the result of a dog and bear coming in contact with one another and a human intervening to save their pet.
- Wolves

But unlike the Big Bad Wolf we’ve heard about in fairy tales, wolves are rarely aggressive toward humans – a fact only confirmed by USDA records, which indicate there hasn’t been a wolf attack on a human in Wisconsin in modern history. Furthermore, there have only been a handful of attacks in all of North America, most of which occurred when humans were feeding wolves, which is why it’s best to keep a safe distance.
- Brown Recluse Spiders

Aside from the brown recluse, Wisconsin is home to only one other venomous spider – the black widow.
- Rattlesnakes
Adam Baker/Flickr Rattlesnakes in Wisconsin?! Yes, it’s true. Two species – the timber rattler and the eastern massasauga – are native to the Badger State. Luckily, you can easily avoid them since both are typically found in the southwestern portion of the state. On top of that, sightings are rather rare. And if you do come across one, rest assured – though they’re venomous, they’re certainly not the deadliest animal in Wisconsin.
- Cougars
Wisconsin Department of Natural Resources Though the cougar is native to Wisconsin, hundreds of years of hunting have greatly reduced the population. Today, cougar sightings are rare, but they have been a bit more common in recent years. Should you come across one, the DNR suggests slowly backing away from the cougar while simultaneously keeping an eye on it.
