Thailand Snake Note – Bitten by Snake?


If you are bitten by a snake in Thailand or anywhere in Southeast Asia:

1. Lay down on the ground and be calm. Many bites – around 50% – are “DRY” bites, meaning, there is no venom transferred during the bite.

2. Find someone to help you get to the hospital immediately – don’t wait for symptoms to begin, and don’t drive yourself.

Emergency Numbers:

  • 1155 – Tourist Police – English speaking
  • 191 – Thai police nationwide
  • 1669 – Ambulance nationwide
  • 1646 Bangkok ambulance

3. Stay as still as possible. Tell someone or write down what you can remember about the snake – Color? Thickness? Pattern? Was it in a tree? On ground? Identifying the snake is very important so you get the right antivenin, if one is needed.

4. Rinse the snakebite site with water if someone can bring it to you. Don’t get up to get water, stay laying down. Do not touch the bite site, or massage it, rub it, cut it open, or do anything to the site at all.


1. If the snake that bit you is a Pit Viper – any green or brown viper, just rinse the area with water and get to the hospital as soon as you can. Pit viper bites can take many hours and even days to become life-threatening. Pit Viper bites may burn and possibly throb at the bite site. Do NOT wrap a Pit Viper bite.

2. If the snake was a Krait, King Cobra, Coral Snake, or Keelback, you can apply an elastic wrap (or strips of any cloth) to the affected arm or leg, starting at the fingers (toes) and working your way up. Go directly over the bite site. The tension in the wrap should be firm, but a finger should be able to go under the wrap.

Snakes of this type have venom that is primarily neurotoxic, and affects nerve connections. The venom may act very fast – about 10 minutes, or you may have at least a couple hours before severe effects begin. Wrap the limb and get to a hospital quickly.

3. If the snake was one of the other cobras – Monocled or Spitting Cobras, you should not wrap the bite site unless you are more than 10 minutes away from a major hospital. If you are in a remote location – wrap the bite immediately. Wrap the bite immediately for children.

Some symptoms of envenomation are: vomiting, dizziness, severe headache, weakness, slowing of heart rate and/or breathing. Cobras have venom which is both neurotoxic and necrotoxic, meaning it can severely damage tissue at the bite site – especially when wrapped.

If you begin having any serious symptoms soon after a Cobra bite, immediately apply a snug pressure wrap starting at the foot or hand of the bitten limb and moving up the limb. Get to a hospital immediately – having someone take you in a car, truck, or sitting between between two people riding a motorbike. DO NOT DELAY.


1. If you do NOT KNOW what type of snake it was that bit you, go to the hospital immediately. Do not wait for symptoms to develop. Ideally you will be at a hospital within 10-15 minutes of the bite, and they can monitor symptoms. If you have a severe burning or throbbing at the bite site, do not wrap the bite – it is likely to be a Pit Viper or Cobra bite. HOWEVER, if you have nausea, stomach pain, breathing or speech difficulties, or drooping eyelids, wrap it immediately and go to the hospital fast.

2. At the hospital, antivenin is given AFTER you start to have symptoms, not before. Some bites are “dry bites” and inject no venom. 

Caution… antivenin (also called antivenom) can cause severe allergic reaction which sometimes results in anaphylactic shock – a potentially deadly complication. Get good advice on the necessity of antivenin before it is administered. The doctors should do a test to see if you’re allergic to it first before full-scale administration of antivenin. They can also administer the first vial extra slowly and remain prepared for symptoms of shock in case of allergy.

One doctor I know well insists that antivenom should not be given until a syringe of epinephrine is on the table – in case of anaphylactic shock. He has found an approximately 30% instance of bad reaction against the antivenom.

Insist on it!

Here is how the test for sensitivity to antivenin is administered (from Queen Saovabha Memorial Institute, Bangkok): “Since the antivenin is prepared from horse serum, sensitization to heterologous protein may occur in some individuals. To avoid serious allergic reactions, skin test should be performed prior to the administration by injection of 0.02 ml of 1:100 antivenin dilution intradermally. It should be noted that the skin test may not predict the anaphylaxis nor delay serum sickness reactions.”

Do Not:

  • Suck the poison out or use any devices to suck out the venom, it can cause more damage to tissue if it is a viper bite.
  • Use a tourniquet, electro-shock, or massage
  • Use ice over the wound
  • Drink alcohol, food, or use aspirin or drugs or medicine of any kind.
  • Use herbal remedies – ingested or applied to the bite site.

Homalopsis buccata Almost Rips My Finger Off

(Page Updated: 6 September 2016)

OK, exaggerating a bit.

OK, a lot.

There is nothing quite like a bite from a snake, when you’re completely not expecting it. I’ve caught a number of these “Puff Faced Water Snakes” – Homalopsis buccata, and while one bit the tongs, none has ever attempted to strike at me. That changed the other night while on a herping trip with Courtney from North Carolina in the states.

I grabbed it fine the first time, and it death-rolled so fiercely I thought it was going to break it’s own neck. I let it go back on the ground by the pond I’d just picked it up at.

The flashlight was shining right in his face – and I was coming up on the approach from behind, but, in hindsight – a bit too much to the side, and he could still see my hand coming. He twisted and struck backward and sideways to grab my middle finger fiercely. I did the twitch, you know, where you jerk your arm in an exaggerated fashion, twirling the snake around like a circus baton, by the mouth on your finger – putting the teeth MUCH deeper than they were originally? Yeah, I did that.

He was NOT letting go, so I asked Courtney to gently put the snake hook point through the jaw between my finger and the joint. Eventually the top opened enough, and then I snuck the bottom finger out. No re-bite, which I was thankful for.

This was a juvenile, but these snakes have powerful jaws, and 26 teeth (I counted the puncture marks on my finger). I was bleeding good, and Courtney got a few pics. Will put one up when she sends me one.

Though a snake is not “known” to bite… do not take it for granted. Practice the same techniques as always to keep from getting bitten. Twenty-six teeth in your finger is not a good feeling… more importantly, you could break some of them in your finger – harming the snake.

Snake Bite! Thai Man Bitten by Monocled Cobra (Naja)

Thai man bitten by a monocled cobra - Naja kaouthia - in Thailand at a snake show
Closeup of cobra bite site on inner right thigh.

I was visiting my friends at the snake show yesterday. One of them was bitten 5 days ago by a Naja kaouthia during one of the shows. It bit his leg through the pants – and got him with both fangs.

Nobody expects this to be a life-threatening bite because he has been bitten 4 times in total now – by the Naja kaouthia (monocled cobra). Humans build up a resistance to the venom over time, and to see the small wound that he has now – it’s hard to believe one of the most deadly snakes in the world bit him.

I’ll attach a video here of me interviewing Dtom and Jackie about how the bite happened – when I get a faster internet connection – right now it’s junk and not working well for a big upload to YouTube.

Most Likely Venomous To Bite You? Malayan Pit Viper

Brown Malayan Pit Viper in Thailand. These are deadly snakes if you don't get immediate treatment.

The Malayan Pit Viper (Calloselasma rhodostoma) is the venomous (bad) snake that is most likely to bite you. They have the habit of lying in the short or long grass and just waiting for prey to walk by. If human footsteps are coming close – it doesn’t attempt to move, it just sits there.

This is why the Malayan Pit Viper is the cause of most of the serious bites in Thailand, and Malaysia. They just don’t get out of the way, or flare up a hood or anything. They are what we call lazy snakes, and they’re quite deadly too. This snake is responsible for more deaths in Thailand than any other.

However, if you make it to the hospital for the antivenin quickly you will likely be fine. Some herpetologists call the Malayan pit viper the “finger rotters”. Their venom is cytotoxic and destroys all cells of the body – including bone. Their venom dissolves bone… it’s quite harsh stuff and you DON’T want to be bitten by this snake because you’ll likely lose part of whatever what bitten.

These Thailand snakes are most active during the night time, but, they seem to just sleep in the open grass during the day too. BE CAREFUL NOT TO STEP NEAR THIS SNAKE. Their bite is vicious and fangs go deep.

Thailand Snake Note – If Bitten by Snake?

If you are bitten by a snake in Thailand it’s a good idea to immediately wrap an elastic bandage, shirt, whatever you have directly on top of the wound, and if the wrap is long enough – continue to wrap above and below the wound as well.

Get to a hospital. DON’T READ THE REST OF THIS  –  GO NOW.

There are more than 60 species of venomous snake in Thailand. Some are quite deadly. Most, rather harmless. The ones you generally have to look out for are:

  • King Cobra
  • Monocled Cobra
  • Equatorial Spitting Cobras
  • Indochinese Spitting Cobras
  • Malayan Kraits
  • Malayan Pit Vipers
  • All Pit Vipers
  • Russel’s Viper

I may have forgotten some, but I just wanted to list those that you are most likely to be bitten by – and be in serious trouble. These are the deadly snakes. More than likely you’d be bitten by either of two – the Russell’s Viper and the Malayan Pit Viper, both very common and both quite deadly if not treated immediately.
