Six species of rattlesnakes can be found in California. Rattlesnake habitats are located from below sea level to about 11,000 feet elevation. It is the only native venomous snake in our state.

Rattlesnakes have the most highly developed venom system of all snakes. The venom is produced in glands behind the eyes. The venom then flows through ducts and out their hollow fangs. The venom is used to subdue prey, which is then swallowed whole.

While rattlesnakes are an important part of the ecosystem, it is understandable that most people would like to avoid them. UC IPM’s Rattlesnake Pest Note is full of great, practical advice to help minimize the likelihood of interactions between rattlesnakes and humans.

Topics include:

• Biology and behavior
• Snake bites and initial first aid guidelines
• Legal status
• Management options
