The mere mention of venomous snakes can send shivers down one’s spine.
While venomous snakes can be found across various regions of the United States, certain states stand out as hotspots, harboring a higher diversity and density of these serpentine predators.
According to a report by ABC News, each year in the U.S., roughly 7,000 to 8,000 people are bitten by venomous snakes, resulting in about five fatalities1 and significant injuries—of which 10% and 44% of those bitten suffer permanent damage.
This highlights the importance of being vigilant and informed about these creatures, especially in states known for their high populations of venomous snakes.
1. Arizona
While Texas takes the prize for the state with the highest overall snake population (a staggering 800,000+), it’s the hot and arid Arizona that claims the infamous title for harboring the most venomous species within its borders.
With a favorable desert climate and varied terrain, Arizona provides the perfect playground for 21 of venomous snake species found in the United States. This sun-scorched state is basically the venomous snake capital of America!
From the extremely venomous western diamondback rattlesnake to the well-known sidewinder rattlesnakes, Arizona’s deserts, rocky canyon areas, and even places like golf courses in cities are perfect homes for these dangerous snakes. Species like the ridgenose rattlesnake, Hopi rattlesnake, and Arizona black rattlesnake are found only in this southwestern snake hotspot region.
But Arizona isn’t the only dangerously venomous state worth watching your step in…
2. Texas
While it may not top the charts for total snake population numbers, Texas does rank high for its diversity of snake species. The state is home to over 65 native and non-native snake species, many of which are venomous.
Of these many snake varieties, around 15 species are considered highly venomous, including copperheads, cottonmouths (water moccasins), coral snakes, and various rattlesnake types
While rattlers like the western diamondback get top venomous billing, run-ins with feisty copperheads and water moccasins are alarmingly common in residential areas like Dallas as development expands into former habitats.
The state ranks 6th in the nation for snake bites per year, with an average of 44.2 snake bites per million people annually.
3. Florida
While the arid regions of the Southwest may be the first to come to mind when thinking of venomous snake hotspots, Florida’s subtropical climate and diverse ecosystems also provide ideal conditions for a thriving serpentine population.
Among the venomous species found in Florida, the Eastern Diamondback Rattlesnake (Crotalus adamanteus) stands out as a formidable presence. This massive rattlesnake, one of the largest in the world, is known for its potent venom and impressive size, with some individuals reaching lengths of over 8 feet.
4. California
While not as densely populated as some of the other states on this list, California is nonetheless home to a variety of venomous species, including several species of rattlesnakes and coral snakes.
One of the most notable venomous snakes found in California is the Mojave Rattlesnake (Crotalus scutulatus), a species known for its potent neurotoxic venom and aggressive behavior.
Another venomous species that calls California home is the Sidewinder Rattlesnake (Crotalus cerastes), a desert-dwelling serpent famous for its unique sideways slithering technique.
5. New Mexico
Rounding out the top five is New Mexico, a state that may not boast the sheer numbers of snakes found in some of its neighboring states, but it is nonetheless a hotspot for venomous serpents, particularly rattlesnakes.
The usual suspects like western diamondbacks are commonplace, but more unique species like the black-tailed rattlesnake and the Ridge-nosed rattler are found within New Mexico’s vast deserts and rocky canyons.
