This Is How Many Types of Venomous Snakes Are in Your State
Check out a full list of the most dangerous snakes potentially lurking in your backyard.

For those of us who have a healthy fear of snakes, it's usually best not to think about them at all. When we do think about them, it's often just to focus on the largely reassuring facts: Snake bites are pretty rare, and very few people actually die from them. At the same time, it's important to be aware of the risk that does exist—however unlikely it may be—and that requires some knowledge of the highly venomous snakes lurking in almost every U.S. state.
If you're concerned about the dangerous critters that might be slithering through your backyard, you should remember that your proximity to snakes has a lot to do with where exactly you live. Nevertheless, you still ought to know which venomous snakes make their home in your state. Antivenom brand CroFab, which helps make treatment for snake bites, put together a full list of the venomous snakes across the U.S. Read on to find out how many of these deadly creatures reside in your state, and which snake-heavy states you may want to avoid entirely.
