As temperatures rise in Southern California, rattlesnake activity is increasing on local trails, creating potential hazards for outdoor enthusiasts. A recent incident in Irvine, reported by the Los Angeles Times, highlighted the dangers when a 25-year-old man tragically died after being bitten by a rattlesnake while cycling. Animal control agencies are issuing warnings as snake sightings become more frequent with the onset of warm weather, noting that rattlesnakes often venture onto trails in the early hours to bask in the sun.
