Southern California Rattlesnake Attacks: How to Protect Yourself
Warm weather increases encounters on trails, in yards and near brush. Learn how to avoid a bite and what to do during an emergency.
Residents, hikers, outdoor workers and pet owners across Southern California are being reminded to stay alert as warm conditions increase the likelihood of rattlesnake encounters.
Rattlesnakes are found throughout much of California and may be active around hiking trails, rocky hillsides, tall grass, woodpiles, garages, gardens and neighborhoods near open space. Most snakes try to avoid people, but they may strike when stepped on, surprised, cornered or handled.
A rattlesnake may not always rattle before striking. Anyone spending time outdoors should watch the ground carefully, keep a safe distance from wildlife and know how to respond to a possible bite.
Call 911 immediately. In California, Poison Control is available at 1-800-222-1222.
How to prevent an encounter
On trails
- Stay on marked paths and avoid tall grass or dense brush.
- Wear closed-toe hiking boots, long pants and thick socks.
- Look before stepping over rocks, logs or fallen branches.
- Never place your hands into holes, rock crevices or brush you cannot see through.
Around the home
- Remove clutter, weeds, boards and debris that can provide hiding places.
- Keep pet food and rodents under control because they may attract snakes.
- Use a flashlight when walking outside at night.
- Seal gaps beneath doors and around garages, sheds and foundations.
Children and pets
- Keep children close in rocky or brush-covered areas.
- Keep dogs on a short leash and away from holes and vegetation.
- Do not allow pets to investigate a snake, even if it appears dead.
When you see a snake
- Stop, stay calm and slowly back away.
- Give the snake plenty of space and a clear escape route.
- Never touch, trap, tease or attempt to kill it.
- Contact local animal control or a qualified snake-removal service when necessary.
What to do after a rattlesnake bite
- Call 911 immediately. Do not wait for symptoms to become severe.
- Move away from the snake without trying to capture or photograph it.
- Stay as calm and still as possible. Limit unnecessary walking or movement.
- Remove rings, watches and tight clothing before swelling begins.
- Keep the bitten area in a comfortable, neutral position.
- Cover the area loosely with a clean, dry dressing if available.
- Do not drive yourself. Venom may cause weakness, dizziness or loss of consciousness.
Dangerous treatments to avoid
- Do not cut the wound or try to suck out the venom.
- Do not apply ice, heat, chemicals or electric shock.
- Do not use a tourniquet or tightly wrap the limb.
- Do not drink alcohol or caffeine.
- Do not take aspirin, ibuprofen or naproxen unless instructed by a medical professional.
- Do not delay emergency care while attempting to identify the snake.
Possible symptoms
Symptoms can include puncture marks, severe pain, rapid swelling, bruising, bleeding, nausea, weakness, numbness, breathing difficulty, changes in vision and shock. Some bites may initially appear mild, so professional evaluation is still essential.
The key message
Watch where you step, stay on established trails, supervise children and pets, and leave every snake alone. Fast emergency treatment offers the best chance of limiting serious complications.
