At the time of this writing, two Southern Californians have died following rattlesnake bites this year. A 46-year-old woman was bitten while hiking at Wildwood Regional Park in Thousand Oaks, California and a 25-year-old man was bitten while mountain biking in Irvine on February 1, 2026. According to news reports, he succumbed after spending about a month in intensive care. A third statewide rattlesnake death occurred in Northern California this year, making 2026 an unusually deadly year statewide (about double the historical average of under one death/year). Multiple outlets attribute this specifically to an unseasonably warm late winter that brought snakes out earlier than hikers expected — not increased aggression or population growth.
Understandably, these tragic events generated considerable media attention—and with it, a fair amount of speculation and concern. Are rattlesnake populations increasing? Are rattlesnakes becoming more aggressive? Is their venom becoming more potent? Do we need to control their populations? Should we stop hiking in our natural areas?
Despite these recent incidents, there is little reason to conclude that rattlesnakes are suddenly becoming more dangerous or that we need to fear our local wildlands…
