Rattlesnake characteristics

Rattlesnakes are the only poisonous snakes native to Southern California.

Notable characteristics are:

• Distinctive rattle at end of tail. A vibrating rattle causes a rattling sound. However, rattlesnakes don't always rattle before striking.
• Broad triangular head, heavy-bodied frame, and slender neck. Length: 1 to 6 feet.
• Vertically elliptical pupils

See the California Poison Control System for more information on rattlesnakes.

Avoid snakes

Snakes are found where rodents and small mammals live. During the day, they often sun themselves on rocks and ledges. Snakes usually try to escape and do not attack unless cornered.

• Stay alert when walking near canyons or undeveloped land.
• If you see a snake, do not disturb it. Move away quickly.
• If you hear a rattlesnake, stand still until you are sure of its location, then move away quickly.
• Snake-proof buildings and yards located near canyons or undeveloped land.
• Install tight-fitting doors, screens, and crawl space covers.
• Block all cracks and holes in foundations and floors.
• Snake-proof fences by installing quarter-inch mesh hardware cloth, minimum height 36 inches. Bury the bottom edge of the mesh cloth a few inches below ground level.
• Clear away vegetation and debris. Snakes use vegetation or debris for nesting areas and climbing.
• Eliminate sources of food, water, and outdoor hiding places in the immediate area. Reduce gopher, rabbit, ground squirrel, rat and mouse populations.
• Examine playgrounds before allowing children to enter.
• Never step or reach into an area you cannot see.

In case of snake bite

Rattlesnake bites rarely result in death. Of the 8,000 people bitten annually, only about 12 die from the bite. If a bite occurs:

1. Remain calm.
2. Call 9-1-1 and get the victim to the hospital immediately.
3. Immobilize the bitten limb. Don't apply a tourniquet or constriction band and don't attempt to cut the wound or suck out the venom. Don't apply ice to the wound.
4. Wash the skin over the bite with soap and water. Cover the wound.
5. Don't give the victim any form of alcohol.
