Rattlesnakes

While rarely fatal, rattlesnake bites are extremely painful and destructive.

What to Know

Thirteen species of rattlesnakes have been identified in Arizona and extra caution should be taken when being outdoors when the daytime temperature stays above 82 degrees Fahrenheit.
Rattlesnakes can be encountered at anytime during the year but in March and April, rattlesnakes become more active and move to areas where they can soak up the sun.
During hot summer months, they are more active at night. After the start of the August monsoons, they become the most active of the year.
The shaking of the rattle can serve as a warning but not always – rattlesnakes can strike without warning or making a sound.
They can strike 1/4 to 1/2 of their body length – rattlesnakes in Arizona can be of different lengths.
Babies are typically born at the end of July and are capable of biting from birth.
