Do wear your tall boots wherever Rattlesnakes might be lurking. Having been bit once, you DO NOT want to go thru the treatment and healing. And if once bit, you are MUCH more susceptible to the venom damage, death, with a second bite.
You might ID your local varieties of Rattlesnakes, then call the local hospitals to see if they carry anti-venom for those snake varieties? Anti-venom (back when I got bit) needed to be snake specific to be really helpful. The ER folks did NOT believe me when I told them it was an Eastern Diamondback because “Those snakes are extinct around here.” That was Baton Rouge Louisiana. Not believing me held up treatment with correct anti-venom! I finally got a visit from a Gov’t Wildlife guy with a picture snake book, so I could point out the one who bit me. He was VERY excited, those snakes had not been seen locally in YEARS! I just read an article about Eastern Diamondbacks big population recovery in Louisiana!! Ha ha
Having anti-venom on hand for your kind of snakes will help speed recovery faster. It is expensive, hospital may argue about keeping it stocked. It does have expiration dates, could be a dead loss to the hospital if not used. Last I knew, each shot was $2500.00. I needed a lot of shots. Do you have a lot of bites in your area? That could help or hinder hospital wanting to stock anti-venom shots.
Louisiana had a quantity of poison snakebites, were used to dealing with them. I made the National statistics for that year! Common bites were Copperhead and Cottonmouths in the cane fields, not Rattlesnakes. And the way people responded to me after finding I had been snakebit was bizarre! Like i could rub off on them! A couple cleaning ladies ran out screaming! Literally!! Others wanted to tell me of relatives who died from getting bitten. A group of interns visiting in the “dark of night” were chock full of questions! “Did it hurt, was I hurting elsewhere, what did we do after the bite?” I was not at my best being sleep deprived from visitors! I think folks down there consider snakebite a death sentence, to die of fright or may totally give up fighting it.
Do NOT try suckling out the venom, it could kill the rescuer! Ice the bite, keep bite location BELOW the heart if possible. I had to sleep sitting up for a week with bites on the foot. Lots of shots and blood draws every couple hours to see if the venom was killing blood cells, checking and drawing on leg to track swelling. Bite itself felt like a wasp sting, the least painful part of things! No hallucinations, spasms or fading away as seen in movies.
