REDWOOD VALLEY, CA — Authorities in Mendocino County have confirmed the third fatal snakebite in California this year, a tragic sign that “rattlesnake season” has arrived with a vengeance.
The Mendocino County Sheriff’s Office reported on Thursday that a 78-year-old woman from Redwood Valley died earlier this month following a snake-related incident. The woman was walking in a rural area on April 8 when she was bitten three times. Despite receiving hospital treatment, her condition deteriorated, and she passed away on April 10.
The Cause of Death
Following a post-mortem examination, the forensic pathologist determined the death was accidental. The sheriff’s office stated the cause of death was disseminated intravascular coagulopathy (DIC)—a serious condition where blood clots form throughout the body—and snake envenomation.
While the specific snake species was not identified, the California Department of Fish and Wildlife notes that rattlesnakes are the only venomous snakes native to the state.
A Deadly Start to 2026
This death marks the third fatality in California since February, signaling a dangerous spike in encounters as record-breaking heat drives snakes out of hibernation earlier than usual.
- February 1 (Irvine): 25-year-old Julian Hernandez was bitten while mountain biking at the Quail Hill Trailhead. He fought for his life in the ICU for a month before passing away on March 4.
- March 19 (Ventura County): A 46-year-old woman died from rattlesnake venom toxicity.
- April (Montecito): Two non-fatal bites were reported on the Buena Vista Trail, including a hiker bitten on her ankle.
Why are Encounters Increasing?
Experts say an unseasonably warm March heatwave pushed rattlesnakes out of their winter retreats early. Rattlesnake season typically runs from April through October, but the recent spike in temperatures has made the reptiles more active and aggressive than usual for this time of year.
Northern Pacific rattlesnakes are common in the Central Valley and Northern California, while Mojave and Western Diamondbacks dominate the southern and desert regions.
Safety Guide: What to Do If Bitten
While fatal bites are statistically rare—with only 5 to 6 deaths per year across the U.S.—medical experts warn that permanent injury can occur in up to 44% of cases if treatment is delayed.
If you encounter or are bitten by a snake:
- Stay Calm: Do not panic; keep your heart rate down.
- Call 911 Immediately: Antivenom is the only effective treatment.
- Positioning: Keep the bitten area lower than your heart.
- What NOT to do: Do not use a tourniquet, do not try to suck out the venom, and do not apply ice.
