Rattlesnakes

April 21, 2022

Question: Are rattlesnakes aggressive or do they typically avoid confrontation?

Answer: Rattlesnakes are not aggressive by nature, but they will defend themselves when threatened. If left alone, they will typically move away from a threat, not toward it. If rattlesnakes are unable to escape, they typically signal advance notice of an attack by taking a defensive posture and rattling. Biting is considered last resort. Venom for a rattlesnake is meant for prey immobilization and digestion. It can take weeks for a rattlesnake to replenish after envenomation. Most bites occur when someone does not see a rattlesnake or deliberately puts themselves in harm’s way. Being aware of where you step or put your hands when in rattlesnake country is the best way to avoid being bitten.

Rattlesnakes are distributed broadly across California but are typically found in open habitats like grasslands, savanna and desert. They prefer to live in and around rock outcrops when available. When they are found in homes and yards, it’s usually along a wildland-urban interface. California residents can make their yards rattlesnake safe by removing objects that attract them and their prey. This can include keeping vegetation away from fences, removing piles of boards or rocks and repairing potential access points.
