Thailand’s Very Common Non-Venomous Snakes
(Last updated: 26 July 2016)
Thailand has around 185 snake species considered non-venomous, or mildly venomous and not a threat to human beings. Though these snakes are not known to be dangerous to humans, that doesn’t mean that they are not. The red-necked keelback, for instance, was a snake kept in aquariums across the world for years before the first deadly bites occurred. Turns out that they have a very strong venom that can be delivered with prolonged or multiple bites. Do be careful with all snakes.
Chrysopelea ornata. Golden Tree Snake
These snakes are very common and it is probably the most commonly seen snake among tourists and Thai locals. They are at home in the bushes and on the ground during the day. They are excellent climbers and prefer to eat the tokay geckos and other geckos. These snakes have a mild venom that can kill or disable birds and other small animals. It is not likely to affect your dog or cat, if bitten.

Ptyas korros. Indo-Chinese Rat Snake
This rat snake is also very common no matter what type of weather or season. These are terrestrial (land-based) snakes with excellent climbing skills. They hunt lizards and other small animals on the ground during daylight hours. Rat snakes have no fangs, but their saliva is known to contain venom proteins. Nobody has been recorded in the literature as having been envenomated significantly by these snakes. Color varies from brown to grey or black.

Coelognathus radiata. Copper-headed Racer / Radiated Rat Snake.
These rat snakes are common around trash bins, and anywhere rats and other rodents can be found. Though they are primarily terrestrial, I have seen one 3-4 meters up a palm tree raiding a bird nest of its young or eggs. These are strong, very fast striking snakes with a lot of nervous energy. Like the other rat snakes, it has no fangs with which to deliver venom.
