Bitten or constricted by your own snake: safe release, wound care and checking the snake

Quick answer

Almost all handling accidents with pet snakes are survivable and minor. Nearly all of the serious damage comes from what the person does in the first two seconds.

A bite from a non-venomous pet snake is rarely dangerous in itself. The injury that sends people to hospital is usually caused by pulling away.

Snake teeth curve backwards, towards the throat. That shape is designed to stop prey escaping, so any backward movement of your hand rakes the teeth through the flesh, tears the wound open, and snaps teeth off inside it. It also injures the snake's jaw and dentition.

• If a snake bites and holds on, stay still and support its body. Do not pull.
• A defensive strike is fast and released immediately. A feeding bite latches and coils, and needs a release technique.
• With a large constrictor, unwrap the coils starting from the tail, never from the head.
• Never handle a large constrictor alone. This is the single most important rule in keeping big snakes.
• Every snake bite that breaks skin is a contaminated puncture wound and needs proper cleaning, whatever the species.

Large constrictors must never be handled alone, and never around the neck or face.

A constricting snake tightens in response to movement and to the small pressure change each time the person exhales, so a coil that felt manageable gets progressively tighter without the snake making any decision to squeeze harder. A person alone cannot reliably unwrap a large boa or python from their own torso.

The widely used keeper rule is one competent adult for roughly every one and a half metres of large constrictor, present in the room, before the snake comes out. Deaths involving pet snakes almost all involve a large constrictor and a keeper who was alone.

Venomous species are outside the scope of any home first aid article. If a venomous snake bites, that is an immediate emergency call, with the species named.

Why pulling away is the whole problem

A python or boa carries rows of fine, sharply recurved teeth on both jaws and on the roof of the mouth. They are not built to cut. They are built to prevent a prey animal from backing out.

When you pull, every one of those teeth acts as a barb. A neat set of punctures becomes a set of ragged lacerations, and teeth shear off at the base and stay in your skin. The same movement wrenches the snake's jaw, which is a delicate structure of loosely connected bones designed to spread apart rather than to resist a pull.

So the correct instinct is the opposite of the natural one. If a snake has hold of you, move towards it rather than away, support its body so it is not hanging by its teeth, and wait.

Most defensive bites do not require any of this. A frightened snake strikes and withdraws in a fraction of a second, and the wound is a row of pinpricks. The bites that hold on are feeding responses, and a snake in feeding mode is not going to change its mind quickly.

Getting a snake to release

Work through these in order. Between each attempt, wait a few seconds, because many snakes let go on their own once they realise what they are holding is not food.

Support the snake first.
Take the weight of its body with your free hand or ask someone to. A snake that feels unsupported grips harder.

Stay still and stop the stimulus.
Reduce movement, lower your voice, and if a warm light or a heat lamp is aimed at your hand, move out of it. A great deal of feeding response is driven by heat.

Run lukewarm water over the snake's head.
A gentle stream of tepid water over the nose and mouth interrupts the feeding response for many snakes. The water must not be hot or cold.

Apply a small amount of alcohol-based liquid to the snout.
A drop of mouthwash, hand sanitiser or spirit on the snake's nose, applied with a cotton bud, is the method most experienced keepers reach for. Keep it away from the eyes. It works because the taste and smell are aversive, not because it harms the snake.

Ease the jaw open from the back, not the front.
If the snake still will not release, a thin blunt object such as a plastic card can be slid gently between the jaws at the corner of the mouth and used to lever, working with the direction of the teeth rather than against them. This is a last resort and it risks the snake's teeth.

Never do these.
Do not pull. Do not hit the snake or shake it. Do not put the snake or its head under cold water. Do not use fire, a heat source, or ammonia near its face.

Unwrapping a constricting snake

Constriction is a reflex. The snake tightens in response to pressure and movement, and it holds while it detects those. It is not deciding to squeeze harder, which is why arguing with the animal achieves nothing and why a calm mechanical approach works.

Start at the tail.
The tail is the weakest and least anchored part of the coil, and it is at the opposite end from the teeth. Uncoiling from the head end brings your face and hands to the mouth and gives the snake something to grip against.

Take one coil at a time and keep it off.
Have a second person hold each freed section away from the body so the snake cannot re-grip while you work on the next.

Do not fight the coil directly.
Pulling against the middle of the loop increases the pressure the snake feels and reinforces the reflex.

Alcohol on the nose can help here too.
The same aversive stimulus that breaks a feeding bite often prompts a constricting snake to release.

Never allow coils near the neck.
This is not a rule about large species only. A snake that reaches the neck can be difficult to remove even at moderate sizes, and pressure on the neck and chest is what makes constriction accidents lethal.

A towel, a card, a bottle of alcohol-based gel and a second person are the entire kit. Have them in the room before the snake comes out, not in a cupboard.

Wound care for the person

Snake bites break skin in a way that looks trivial and behaves like a puncture wound, which is the type most likely to become infected.

Wash under running water for several minutes.
Use plain soap and water and be thorough. Mechanical washing is what removes contamination. This matters more than any antiseptic.

Let it bleed a little.
Do not squeeze aggressively, but do not rush to stop light bleeding either. Bleeding flushes the track.

Look for teeth.
Fine white slivers can remain in the wound, especially after a feeding bite. They are a common reason a bite refuses to heal. If a wound stays painful or a small firm lump develops, that is what to suspect.

Skip the peroxide.
Hydrogen peroxide and undiluted antiseptics damage the tissue that needs to heal and do not improve outcomes over proper washing.

Cover and watch.
Dress the wound and check it daily for spreading redness, heat, swelling, discharge, or a red line tracking up the limb. Any of those needs medical attention.

Get medical advice for the higher-risk bites.
Bites to the hand, particularly over a joint or tendon, bites to the face or eye, deep punctures, bites in anyone with diabetes, immune suppression or on chemotherapy, and any bite where you are not confident the wound is clean. Check that tetanus cover is current.

Mention the reptile.
Reptiles can carry Salmonella, and mentioning that the injury came from a snake changes what a clinician considers. Wash hands thoroughly after any reptile contact, and never handle snakes while eating.

Checking the snake afterwards

The animal is a patient too, and the injuries it takes are the ones owners routinely miss.

Once everyone is calm, a brief look inside the mouth tells you whether teeth were lost and whether the gums were torn.

Look at the mouth once, briefly, when the snake has settled.
Do not do this straight after the incident. Wait until the snake is calm, then have a second person support the body while you gently open the mouth. You are looking for missing or broken teeth, torn gum tissue, bleeding, and anything caught between the teeth.

Watch for the signs of mouth rot over the following weeks.
Damaged gum tissue is the classic entry point for infectious stomatitis. The early signs are reduced appetite, a change in how the snake takes prey, excess or stringy saliva, small yellow or cheesy deposits along the gum line, redness at the tooth line, and swelling of the jaw or under the chin. Any of these needs a reptile vet.

Check the body for damage.
If the snake was pulled, shaken or dropped, run your hands along its length looking for kinks, asymmetry, swelling or a section it will not flex normally, and watch it move. Snakes hide spinal and rib injuries well.

Do not feed immediately.
Give the animal several days of quiet with no handling before the next feed. A stressed snake is more likely to regurgitate, and a sore mouth makes a bad feeding experience that can turn into weeks of refusal.

Do not punish, tap or spray the snake.
Snakes do not learn from correction the way a mammal does, and aversive handling produces a defensive animal that strikes more.

Why it happened, and how to make it not happen again

Working out which of these applies is more useful than any technique.

Feeding response, not aggression.
The classic pattern is an owner who has just handled thawed prey, opened the enclosure at the usual feeding time, or reached in from the front while the snake is expecting food. Wash hands and forearms thoroughly after touching prey, and separate the feeding routine from the handling routine so the snake can tell them apart.

Reaching in from above.
Everything that eats a snake in the wild comes from above. Approaching from the side, and touching the mid-body with a hook or a gentle touch before lifting, tells the snake this is handling rather than predation.

Handling during a shed.
In the blue phase, the spectacle over the eye clouds and the snake is effectively half blind. Almost every normally placid snake becomes defensive. Leave it alone until the shed is complete.

Handling a hungry snake, or one that is due to feed.
The risk rises sharply in the day or two before a scheduled meal.

A new or recently moved snake.
An animal that has not settled into its enclosure is defensive. Give it a settling period before handling.

A gravid female, or a snake in breeding season.
Temperament changes markedly, and this is normal rather than a problem to correct.

Scent contamination.
Rodent bedding on your sleeves, another pet's scent on your hands, or a partner who has handled prey all read as food.

Species differences.
Corn snakes and other small colubrids give minor bites that rarely need more than washing. Ball pythons very rarely bite defensively but have a strong feeding response. Arboreal species such as green tree pythons and emerald tree boas have notably long anterior teeth and give deeper punctures. Boas, Burmese and reticulated pythons are the group where constriction, not the bite, is the real risk, and where the two-person rule is not negotiable.

What never to do

Do not pull your hand away from a snake that has hold of it.

Do not strike, shake, throw or drop a snake that has bitten. You will injure it and you will not get released any faster.

Do not immerse a snake's head in cold water or apply ice.

Do not use flame, a lit cigarette, a heat gun or ammonia near the animal's face. These methods circulate widely and cause serious injury to the snake without working reliably.

Do not pick at a wound to remove teeth with unwashed fingers or a needle. Have it looked at.

Do not let a snake of any size settle coils around a neck for a photograph.

Do not handle a large constrictor alone, even one that has never shown any interest in biting.

Do not resume normal feeding and handling before the snake's mouth has been checked.

Several quiet days without handling, and a delayed next feed, are the aftercare for the snake.

When to get help

For the person, seek medical attention for any bite to the face or eye, any bite over a finger joint or tendon, a deep or ragged wound, a wound you cannot get clean, uncertainty about tetanus cover, or any spreading redness, swelling, heat or discharge in the days afterwards. Say that the injury came from a reptile.

Call emergency services immediately for a venomous species, or for a constriction incident involving the chest or neck.

For the snake, contact a reptile vet if there is bleeding from the mouth that does not stop quickly, visible damage to the gums or jaw, missing teeth with torn tissue, any kink or asymmetry in the body afterwards, or any of the mouth rot signs in the following weeks. Bring the date of the incident, the date of the last feed, and a photograph of the mouth if you were able to take one calmly.
