1. Alaska
Number one state of our list of 10 states with no or least poisonous snakes in America is Alaska. This is the safest country considering venomous snakes; it is the only country with no venomous species. It is often thought that there are no snakes in Alaska at all, which is reasonable, having in mind freezing Alaskan temperatures. Even so, non-poisonous garter snake (of Thamnophis genus), one of the most common American snake species, can rarely be seen wandering in the southernmost parts of Alaska.
