Rattlesnake Bite: What to Do in Arizona

Every rattlesnake bite is a medical emergency. Call 911 immediately, move away from the snake, stay as calm and still as you can, remove rings and watches before swelling starts, and get to an emergency room. Do not apply a tourniquet, do not cut the wound, do not try to suck out venom, and do not apply ice. Antivenom is the treatment, and it works — but it has to be given by clinicians.

Arizona has more rattlesnake species than any other state. Most bites happen between March and October, and a large share happen to people who were trying to move, kill, photograph, or handle the snake.

What to do, in order

Call 911. Do not drive yourself if you can avoid it — bites can cause fainting and rapid deterioration.
Get away from the snake — about 20 feet is plenty. Snakes can strike again, and a surprising number of second bites happen during rescue attempts.
Sit or lie down and keep still. Movement speeds venom through the body.
Remove rings, watches, bracelets, and tight clothing near the bite immediately. Swelling can become dramatic and jewellery turns into a tourniquet you cannot remove later.
Keep the bitten limb at roughly heart level and as still as possible. Splinting it loosely can help.
Mark the leading edge of the swelling with a pen and write the time. This gives the emergency team a rate of progression, which genuinely informs treatment. Repeat every 15 to 30 minutes.
Note the time of the bite and, if you can do it safely from a distance, take a photo of the snake. Never delay care to hunt for it, and never bring it in.
Stay warm and calm. Panic raises heart rate and speeds absorption.

What never to do

Snakebite folklore is dangerous, and most of it comes from films.

No tourniquet or tight constricting band. Concentrating venom in a limb causes far worse local tissue destruction and can cost someone their hand or foot.
No cutting or incising. It does not remove venom; it adds a wound and an infection.
No suction — by mouth or with a kit. Commercial snakebite extractors have been studied and do not work.
No ice or cold packs. Cold worsens tissue damage.
No electric shock. This is a genuine folk remedy and it is genuinely harmful.
No alcohol or caffeine.
No aspirin or ibuprofen. Rattlesnake venom interferes with clotting, and these add bleeding risk. Paracetamol is the safer choice if anything is needed — but let the medics decide.
Do not wait to see how it develops. Roughly a quarter of bites are “dry,” with little or no venom injected, but there is no way to know which yours is until hours have passed. Waiting is a bet with your tissue.
Do not try to kill or capture the snake. This is how people get bitten twice.

What happens at the hospital

You will be assessed and monitored closely — the bite site, the swelling, blood counts, and clotting. If envenomation is significant, you will receive antivenom intravenously, which neutralises circulating venom and is highly effective. Treatment also involves pain control, wound care, tetanus status, and repeated blood tests, because clotting problems can develop or recur over the following days.

At our Emergency Room we have emergency providers on site 24 hours a day and a full laboratory in the building for the blood work this requires. Bites needing prolonged intensive monitoring or specialist care are stabilised here and transferred, with your provider coordinating directly with the receiving team.

Teaching children snake safety

Children in Fountain Hills grow up around rattlesnakes, which is normal and manageable. The rules are simple enough for a five-year-old.

Stop and back away. If you see or hear a snake, freeze, then walk backwards slowly. Do not run past it and do not step over it.

Never touch a snake, even a dead one. Freshly killed snakes can still bite reflexively, and a “stick” in the wash may not be a stick.

Tell an adult straight away — and make it clear they will not be in trouble for it.

Stay on the trail. Do not reach into holes, under rocks, into woodpiles, or through bushes where hands cannot see.

Watch where you put hands and feet when climbing rocks.

Listen. A rattle is a warning, and it means stop. But teach them that a snake may not rattle at all, so a quiet trail is not a safe-by-default trail.

Wear proper shoes — closed-toe, ideally over the ankle — for hiking and yard play.

Worth telling children plainly: a rattlesnake does not want to bite them. It bites when it is frightened and cornered. Giving it room is the entire strategy.

Around the house and yard

Keep the yard clear of woodpiles, rock piles, and dense ground cover near the house. Control rodents, because rodents are what snakes are hunting. Seal gaps under gates and along walls — snakes need very little room. Use a torch at night on paths and around the garage.

If a snake is in your yard, do not deal with it yourself. Fountain Hills residents can contact the local non-emergency line or a licensed relocation service; the Rural/Metro or town animal control resources can advise. Relocation by someone trained is safe, free or cheap, and considerably better than an improvised attempt with a shovel.

And your dog

Dogs get bitten far more often than people, usually on the face, and it is a veterinary emergency — go straight to an emergency vet. A rattlesnake vaccine and professional snake-aversion training both exist and are worth discussing with your vet if you hike with your dog. We treat people, not pets, so have an emergency veterinary number saved before you need it.
