6. Delaware
Twenty different snake species inhabit Delaware, the number 6 on our list of states with no or least poisonous snakes in America, and only one of them is poisonous. That is the famous northern copperhead (Agkistrodon contortrix mockasen), known under many other common names like copperhead moccasin, pilot, poplar leaf, red adder, thunder snakes, etc. It is widely spread throughout the eastern US. It can be found in many habitats, like rocky areas or swampy terrains. It is nicely camouflaged so it can rarely be seen, and that’s what makes them dangerous. Even so, these snakes rarely encounter people and their bites are rarely fatal.
