Don’t let this list discourage you as we will share some tips to help you stay safe during your visit to Thailand.

1. Poisonous Snakes:

When in Thailand, expect to spot a snake in the country area, downtown, and urban Thailand. You may encounter one in grassy lands, canals, rivers, or any good hiding places like garages.

Be cautious. If there is a pit, a hole, a cavity, a snake is there!

You will see a variety of snakes from both harmless to venomous snakes, and passive hiders to aggressive attackers.

Some of the extremely dangerous snakes in Thailand are:

  • Chain Viper
  • Several types Krait
  • Spitting Cobra
  • King Cobra
  • Coral Snakes
  • Pit Vipers
  • Several other types of Cobras

King Cobras are very commonly found in Thailand. They are easy to detect as they keep their heads raised and have a hood under the head. They are as big as 5 meters and may seem very scary. Don’t worry, they won’t attack unless they are threatened. Watch out for Baby King Cobra as they can be more dangerous than adults and can put loads of venom in the body when biting.

Stay far, far away from the Spitting Cobras. They can spit venom in the eyes from as long as 3 meters away. These super venomous snakes are super accurate at throwing. They deliberately target the eyes so the cytotoxins and neurotoxins from the venom can blind the threat.

Monocled Cobras are the deadliest snakes. They are more than seven feet long and are amazingly swift at striking. You may identify them by the round shapes on the back of their hoods. The victims of Monocled Cobras have the highest fatality rate.

Before heading out, wear bottoms that cover your legs. Also, wear long boots. If you must walk in tall grass, take a stick with you and keep hitting it on the ground.

On encountering, most snakes will run away. If they don’t, stay out of their path. Never attack a snake or try to scare it away. If it is an aggressive one, it will not go away and attack instead.

If you are bitten, rush to the nearest hospital or call for help. Don’t worry about identifying the snake. The hospitals in Thailand treat more than 7000 snake bites each year. So, you will be in good hands.

If help is too far away, wash the wound with soap and water, and tie a bandage above the area to stop the poison from spreading. Make sure you don’t tie it too tight to block blood flow.

2. Giant Centipedes

As big as a man’s forearm, the giant centipedes can seem very daunting. You may find them both indoors and outdoors hiding under rocks or logs or sneaking in your shoes or clothing.

In Thailand, most commonly found centipedes are:

  • Chinese Red Headed Centipedes
  • Asian Forest Centipedes

If you encounter one, stay away as it will most likely bite you. Giant centipedes have specially adapted front legs that act like pincers to inject venom. A centipede’s venom is not fatal, but it hurts really bad.

A centipede’s bite-mark resembles that of a snake. If you get bitten, expect to be in immense pain for the next few days. It is recommended to visit a hospital instantly. You will be treated with pain killers and anti-tetanus, as required.

Depending on the envenomation, a medicine may or may not fully help in treating the pain.

In case that help is too far away, wash the bite mark with water. To soothe the pain, you can use ice.

Thank God for their huge size, the giant centipedes are really easy to detect and avoid in day-time. But be careful during the night. To avoid getting bitten by centipedes, don’t walk without shoes. Always give your shoes and clothing a light shrug before putting them on.

Box Jellyfish are very dangerous. There have been incidents when a victim couldn’t make it to the shores because of a heart attack in reaction to the sting.

Jellyfish don’t like a bright sun. So, to avoid them swim on bright sunny days. Moreover, avoid swimming after a storm.
