As an animal lover, snakes have long held a fascination for me. I cannot say I have ever thought about having one as a pet, but that does not lessen my interest in them.
The below collection of snake bite statistics certainly reinforces the danger of getting too close to wild animals and should certainly serve as a warning to those that tread without care through a snake’s habitat.
Luckily, living in the UK, adders are the most venomous snakes we have in the wild. Adders are still a viper, but we are lucky that our indigenous snake population is largely venom-free. However, as this article will show, venomous or not, being bitten by a snake is never fun.
Snake Bite Statistics by State
Did you know that every year, over 7,000 people in the United States are bitten by venomous snakes? But the likelihood of a snake bite varies greatly by state.

Below are nine fascinating snake bite statistics based on individual US states.
North Carolina Has the Highest Bite Rate of 157.8 per Million Population per Year (Healthy Journal)
Out of all fifty states, North Carolina has the highest rate of venomous snakebites in the whole United States. According to data published on TheHealthyJournal, North Carolina reports 157.8 snake encounters per million inhabitants.

With 105.3 bites per million, West Virginia is still more than three times above the national average. Interestingly, despite the high bite rates, West Virginia is home to just two venomous breeds.
Arkansas, Come Third on the List with a Bite Rate of 92.9 (Healthy Journal)
The same article confirmed Arkansas to be the third most active state for venomous snakebites on humans.
Arkansas reports three times the national average, as 92.9 bites per million people in the population. While there are 39 different species native to the state, only two have a venomous bite.
The Snake Bite Rate in Oklahoma Is 61 (Healthy Journal)
The same report also confirmed that Oklahoma is the fourth most bite-rich state, with a reported 61 bites per million, twice the national average. The low numbers are impressive when you think that Oklahoma has 48 different types of snake and 7 venomous species.
Virginia Has a Bite Rate of 48.7 (Healthy Journal)
The state of Virginia is the fifth most active state for venomous snakebites. At 48.7 bites per million people, Virginia is roughly 50% above the national average.

While there are nearly 3,000 people bitten by wild copperheads every year, the death rate remains low. According to TheHealthyJournal, the fatality rate is so rare it measures just 0.01%
Which Is the Deadliest Snake in the World?
The inland taipan is widely recognized as being the deadliest snake in the world. The inland taipan is a snake native to Australia, specifically central Australia.
Thankfully, despite topping the list of the most venomous snakes in the world, the inland taipan is rather shy and highly placid. Additionally, because of their geographical location, inland taipans do not often come into contact with humans.
What Is the Average Lifespan of a Viper?
The average age of a viper is anywhere between 15 and 20 years. However, there are approximately 80 different viper species, and each has its own individual age range.
For every rattlesnake that lives 10–25 years, there is an adder that lives just 5-10. It is impossible to give a single range for an entire snake species.
What Do the Rattles Numbers on a Rattlesnake’s Tail Signify?
The number of rattles on a rattlesnake’s tail signifies nothing in particular. There is a prevailing myth that the number of rattles acts the same as the number of rings in the tree, revealing the snake’s age. However, this is not true.
A new rattle emerges every time a snake sheds its skin, but rattlesnakes do not shed their skin on a regular or annual schedule, so it’s impossible to use this as an aging factor.
Additionally, the rattles on their rail can fall off due to accidents or predator attacks.
How Fast Does a Snake Bite Kill?
The length of time it takes for a snake bite to be fatal depends on the type of snake and how severe the bite is.
The inland taipan, the most venomous snake in the world, kills a human in around 45 minutes. However, a bite from a black mamba can kill as quickly as ten minutes after the bite.
How Could a Poisonous Snake Be Identified?
There are three key ways to identify venomous snakes.
- Broadhead: Most venomous snakes have a wide and triangular head compared to the more ovoid-shaped heads of non-venomous species.
- Cat-like eyes: Venomous snakes have cat-like pupils, meaning they are elliptical rather than round and humanoid,
- Nasal pits: Many venomous snakes are also called pit vipers and have two small nostril-like pits on their nose.
How to Recognize a Copperhead Snake?
The main way to identify a copperhead snake is through its coloration. Much like their name suggests, copperheads have a copper-colored body with a darker hourglass shape running horizontally over their back.
Snakes and other reptiles are fascinating creatures, and while there are many experts that claim they make bad pets, the close relationships between man and snake remain.
The above statistics should serve as a warning that while the chance of dying after being bitten by a snake is very low, snake venom remains a potent toxin that requires urgent and decisive treatment.
Victims of a snakebite, whether it’s in Texas, Florida, or anywhere further afield, need to take care and remain vigilant at all times.
