Other Dangerous Animals Near Indiana’s Lakes and Rivers

When we think of dangerous animals in and around Indiana’s lakes and rivers, our minds often jump to venomous snakes and dangerous fish. However, there are other creatures that can pose risks to humans in these environments.

In this section, we will explore some of the lesser-known dangerous animals near Indiana’s waterways, such as the kissing bug, brown recluse spider, muskrats, and river lampreys.

Kissing Bug

The kissing bug, also known as the triatomine bug, may not be widely recognized as a dangerous creature, but it can transmit a disease known as Chagas disease. While the incidence of Chagas disease in Indiana is relatively low, it is still essential to be aware of the risks associated with kissing bugs.

These bugs feed on the blood of mammals, including humans, during the night. They often bite around the lips or face, hence their name.

If infected with the parasite Trypanosoma cruzi, which causes Chagas disease, the kissing bug can transmit the disease through its feces, which are often rubbed into the bite wound. Chagas disease can lead to serious health complications if left untreated, including heart and digestive system issues.

While the risk of encountering a kissing bug in Indiana is relatively low, it is crucial to be cautious and take preventive measures when spending time near the lakes and rivers where they may be found. This includes sealing gaps in buildings to prevent their entry and practicing good hygiene by washing hands and face after spending time outdoors.

Brown Recluse Spider

The brown recluse spider, known for its venomous bite, is another dangerous animal that could be encountered near Indiana’s lakes and rivers. These spiders are typically light to dark brown and have a distinct violin-shaped mark on their bodies.

While they may be found in a variety of indoor and outdoor environments, they tend to prefer dark, undisturbed areas, such as woodpiles or cluttered garages near water sources. Brown recluse spiders are not naturally aggressive and will typically only bite if they feel threatened or trapped.

However, their venom can cause necrotic wounds and, in rare cases, systemic symptoms. If bitten by a brown recluse spider, it is important to seek medical attention promptly.

To reduce the risk of encountering brown recluse spiders near Indiana’s lakes and rivers, it is important to keep outdoor areas clean and free of clutter. Regularly inspecting and cleaning areas where these spiders may hide, such as sheds or woodpiles, can help minimize the chances of an encounter.


Muskrats are semi-aquatic rodents that inhabit wetlands, lakes, and rivers in Indiana. While they may not seem like dangerous animals, muskrats can pose a risk to humans due to the diseases they may carry.

One such disease is tularemia, also known as rabbit fever, which can be transmitted to humans through direct contact with infected animals or contaminated water. Tularemia can cause flu-like symptoms, including fever, chills, fatigue, and swollen lymph nodes.

In rare cases, it can lead to more severe complications. To reduce the risk of contracting tularemia from muskrats, it is essential to avoid direct contact with these animals and to practice good hygiene when spending time near their habitats.

This includes avoiding drinking untreated water from lakes or rivers where muskrats are prevalent.

River Lamprey

River lampreys are eel-like fish known for their destructive feeding habits. While they are not a direct threat to humans, their presence in Indiana’s rivers can have a negative impact on the local ecology.

These parasitic creatures attach themselves to host fish, using their circular mouths to suck blood and body fluids. This can weaken or even kill the host fish, disrupting the natural balance of the ecosystem.

Efforts are being made to control the population of river lampreys in Indiana’s rivers to minimize their impact on native fish species. These control measures often involve the use of traps or the application of lampricides, which selectively target the lamprey larvae.

By managing the river lamprey population, we can help protect the health and diversity of Indiana’s aquatic ecosystems.


While venomous snakes and dangerous fish may be the first creatures that come to mind when considering the dangers lurking in Indiana’s lakes and rivers, it is important to remember that there are other dangerous animals that should be taken into consideration.
