Thailand Has a Lot of Snakes and Almost None of Them Want to Meet You
The real risk is rubber plantations and the fact that people handle snakes for a living without protective equipment. Here is the actual risk map.
The Thai snake that is most likely to hospitalise you is not the one on the temple wall. It is a fifty-centimetre green pit viper in a rubber plantation in Rayong, and it is not rare, and it is not hiding.
I met a man in the south who was bitten twice, in the same year, in the same plantation, and who told me the second time he was lucky. He was not being dramatic. He was describing a genuinely dangerous job done with genuinely inadequate protection.

Where the risk actually is
Rubber plantations, in the south and the east, in the rain. The Malayan pit viper is the highest-concern species in Thailand and plantations are where the real human snake bites happen. Visitors have essentially no reason to be in a plantation.
Anywhere outdoors at night, in rural areas. Snakes are crepuscular and nocturnal, they are attracted to rodents, and they are not interested in you at all. The mitigation is boring: closed shoes and a torch.
Water edges, rock piles, and anywhere you put your hands without looking. The great majority of snake bites are on the lower leg and the hand, and the great majority of those are the result of stepping on one or reaching into somewhere without looking.
And nowhere in a well-kept resort, a hotel room, or a busy city street. This is worth saying plainly, because visitors are often anxious about Thailand generally, and the answer is that the risk is geographically specific and quite narrow.
Scorpions, and the good news
Thailand has hundreds of scorpion species and the ones you will meet are generally small. There are large forest scorpions in the south, which look alarming and are not the thing you should be planning around.
Do not pick one up. That is the entire safety advice for scorpions, and it is the same advice that applies to everything else here. The severe scorpion envenomation cases in Thailand are agricultural and occupational rather than traveller incidents.
The snakes that matter
The Monocled cobra and the King cobra are the most venomous by volume and both deliver serious neurotoxic venom. The king cobra is genuinely large and genuinely impressive and it is not aggressive; it eats other snakes. Give it a very large berth and do not try to identify it yourself.
The Malayan pit viper, the green pit viper, and the bamboo viper are the haematotoxic ones, the ones that cause the dramatic local swelling, and they are the ones actually encountered.
The banded krait is venomous, is often encountered because it eats other snakes and comes into villages, and is responsible for a disproportionate share of bites, because it is fat, slow, and lies still on paths where people walk.
The hundred other species are not dangerous to you and most of them are not venomous at all. The practical problem is that a visitor cannot identify a snake, and the correct response to an unidentified snake is the same in every case: back away.
What to do if you are bitten
Get away from the snake and get to a hospital. This is the overwhelming priority and everything else is secondary. Antivenom is the treatment, and the only thing that matters about speed is the time to get it.
Keep the person still and calm and lying down, with the bitten limb below heart level. Movement spreads the venom. Panic makes it worse.
Immobilise the limb. Splint it. Remove rings, watches and tight clothing from that limb before the swelling starts, because Thai hands and feet swell dramatically and a ring that fits at the hospital may not fit on the way there.
Take a photograph of the snake if you can do it from a safe distance, or describe it accurately. This genuinely helps the doctor choose an antivenom, and the description can be more useful than a bad photo.
First aid that does more harm than good
This is important, because a lot of what is online is out of date.
Do not cut the wound and do not try to suck out the venom. This was standard advice for decades and it is now understood to be ineffective, because you cannot meaningfully extract venom that has already entered the tissue, and you introduce infection into a wound that will be open for days.
Do not apply a tourniquet. It has been shown to be harmful, it increases tissue damage, and modern guidance is immobilisation instead.
Do not wash the wound aggressively, and do not try to identify the species by the pattern of bites. Venom identification from bite marks is not reliable.
Do not wait to see how bad it is. A neurotoxic bite can deteriorate over hours and the decision to treat should be made early by a doctor, not at midnight by you.
And do not trust traditional remedies. There is a real local practice of applying a tourniquet and herbal paste and it has been practised for a long time, and it is not compatible with modern antivenom treatment.
One more thing worth saying
The genuine long-term risk in Thailand is not a snake bite, it is a motorbike accident, and it is orders of magnitude more likely. Thailand has one of the highest road fatality rates in the world and almost all of it is two-wheeled, almost all of it is in the 15 to 35 age band, and a great deal of it is a visitor who was on day two and had not yet adjusted.
Snakes are the thing people are frightened of, and the thing they should actually be careful about is the road. Both are covered properly in the road-accidents post, and that is the one worth reading twice.
