Spring’s rising temperatures also signal another season -- rattlesnake season.

Snakes have already bitten seven people in Arizona this year. None of the bites were fatal. Usually, snakes are most active April through October, but recent warm temperatures have brought them out earlier.

Herpetologists say you are most likely to encounter snakes in the morning or evening. They say if you hear or see a snake, move away slowly.  Medical experts say if you are bitten, seek  immediate medical attention and avoid tourniquets or cuttings, which may cause more damage.
