Some snakes are actually venomous, meaning they can inject venom into you via a bite or sting.
While baby rattlesnake venom can be more toxic, contrary to popular belief, they can control how much they release.
Wild snakes want nothing to do with humans and they only bite as a last resort, so you’ll have nothing to worry about if you keep your distance.
The best thing you can do is basically nothing and go to the hospital immediately.
Some non-venomous snakes have triangular heads, too. The only certain way to know is to research the snakes in your area.
