First Aid for Snake Bites

Fact Checked

Even though most of the snakes in North America are not poisonous they can trigger allergic reactions in many people. Thousands of people are sufferers of snake bites, with trekkers and people living in the wilderness being the most susceptible to snake bites.

Make sure you are safe from poisonous snakes such as rattlesnakes, water moccasins, coral snakes, copperheads, vipers and cobras as their bites can be deleterious to the human health and may cause death.

Learn the proper skills to recognize and manage victims with snake bites by taking St Mark James first aid training.

You can recognize a poisonous snake with the following characteristics:

  • Coral snakes: triangular heads, depression in the middle between the nostril and the eye on both sides of the head-also known as pit vipers. All snakes have eyes like slits except coral snakes. Coral snakes have yellow, black or red rings on their bodies.
  • Rattlesnakes: their bodies end with rattles.
  • Water moccasins: a white, cotton-like lining of the mouth.


If you ever see a snake, do not be shocked or afraid and do not try to harm it. Simply back away slowly without notifying the snake as many snakes bite you when you bother them or invade their territory.

  • Do NOT apply ice to the wound.
  • Do NOT try to cut the wound.
  • Do NOT try to remove the venom by sucking or applying pressure on the affected region.
