Venomous Snakes

Kansas is home to 42 different kinds of snakes. All are beneficial for the environment, and most are harmless, but 6 venomous species pose risk to humans.

How Can I Tell if a Snake is Venomous?

Some of a snake's natural features can help determine if it has venom or not. However, it is safest to consider all snakes as potentially dangerous and walk away.

Snakes with venom (venomous)

  • Diamond- or triangle-shaped head
  • Elliptical or "cat like" pupils
  • Long fangs
  • Pits located between the eye and nostril
  • May have a rattle


Snakes without venom (harmless)

  • Smooth head that is like the body
  • Round pupils
  • No pits
  • No fangs, small rows of teeth

Note: These are general identification tips and don't always apply.

Tips to Prevent Snake Bites

Snakes in Kansas are most active from April through October, with most bites occurring when the snake is frightened and acting defensively. However, by taking extra precautions, many of these bites are preventable.
  • Watch your step. Consider using a walking stick when hiking. Don’t stick your hands under rock ledges, logs or stumps where snakes can hide. Use a flashlight at night when you’re outside.
  • Wear sturdy boots or shoes when you’re outside, especially when gardening, hiking or camping. Wear leather gloves when handling brush and debris.
  • Don’t try to pick it up or kill it. It can bite you while you’re trying to grab it. A dead snake, or even a snake’s detached head, can still bite because of its bite reflex.
  • Planning to spend time in a snake-prone area? It’s best not to go alone in case of an emergency. Also bring a fully charged phone.
