Learn to Identify Arizona’s Venomous Snakes
Snake identification should never involve getting close to or handling a snake. Different species can have similar colors and patterns, and features such as head shape or pupil shape should not be used alone to determine whether a snake is dangerous.
Our individual identification guides provide more detailed information about specific species, including their appearance, habitat, behavior, and safety considerations.
Where Venomous Snakes Are Found
Venomous snakes can occur in many parts of Arizona. Depending on the species, they may be encountered in deserts, rocky areas, grasslands, foothills, canyons, and areas near open land.
They can also occasionally appear around homes when suitable shelter, prey, or access to surrounding habitat is available.

Staying Safe Around Venomous Snakes
The safest approach is to give any snake plenty of space. Never try to catch, handle, corner, or kill a snake.
If you encounter a snake while hiking or outdoors, stop, maintain a safe distance, and allow the snake a chance to move away. If necessary, calmly change your route.
