This is a blog post I did in March of 2016. After watching our neighbor in the desert today chasing a snake away from his motorhome, I thought I'd repost it.
There is an article from USA Today, 03/08/16 - http://www.usatoday.com/story/news/nation-now/2016/03/08/man-bitten-rattlesnake-arizona/81469830/ regarding a gentleman who was bit by a rattlesnake Sunday. He was interviewed in the hospital. Also, in the article it mentions “Arizona Game and Fish Department spokesman Randall Babb said the peak season for rattlesnake bites varies between years, and often depends on outside temperature. With this year getting warmer so early, rattlesnake season may have started earlier as well, he added. Sunday's high temperature was 80 degrees, according to AccuWeather.com. Babb also noted that there are 13 different species of rattlesnakes in Arizona, some with more toxic venom than others.”
With that in mind, I looked up Arizona rattlesnakes and came up with this information on the Arizona Game and Fish web site. Here is the link to the original page: https://www.azgfd.com/wildlife/livingwith/rattlesnakes.
