How can I avoid snakebites?

Snakes are most active in the spring, early summer and fall. Most snakebites occur between April and October, when weather is warm and outdoor activities are popular.

Although most snakes are not poisonous, there are several kinds of snakes in the United States that are poisonous. These include rattlesnakes, water moccasins (also called cottonmouths), copperheads and coral snakes. Here are some things you can do to reduce your risk of snakebite:

  • Regularly trim hedges, keep your lawn mowed and remove brush from your yard and any nearby vacant lots. This will reduce the number of places where snakes like to live.
  • Don't allow children to play in vacant lots with tall grass and weeds.
  • Always use tongs when moving firewood, brush or lumber. This will safely expose any snakes that may be hidden underneath.
  • When moving through areas with tall grass and weeds, always poke at the ground ahead of you with a long stick or pole to scare any snakes away.
  • Wear loose, long pants and tall boots when working or walking in areas where snakes are likely to be.
  • Never handle snakes, even dead ones. If you see a snake, slowly back away from it.
  • Always sleep on a cot when camping.
  • Be aware of snakes if you are swimming or wading in rivers, lakes or other bodies of water (this includes areas covered with water due to flooding).
  • Learn to identify poisonous snakes and avoid them.

What are the signs of a snakebite?

You may not always know you were bitten by a snake, especially if you were bitten in water or tall grass. Signs and symptoms of a snakebite may include the following:

  • Two puncture marks at the wound
  • Redness or swelling around the wound
  • Severe pain
  • Nausea
  • Vomiting
  • Difficulty breathing
  • Fever-like symptoms, such as sweating
  • Numbness or tingling sensation in the fingers, toes or area around the wound
  • Blurry vision
  • Diarrhea
  • Fainting
  • Convulsions
  • Rapid pulse

What should I do if I get a snakebite?

A bite from a poisonous snake is a medical emergency. If you or someone else gets bitten by a snake, get help immediately.

What to do if you get bitten by a snake:

  • Remain calm and call for help.
  • If you are alone, try to get to the nearest hospital as soon as you can.
  • Restrict movement as much as possible and try to keep the wound just below the level of your heart. This will reduce the spread of venom.
  • Take off any jewelry or tight clothing near the bite before swelling starts.
  • Try to remember what the snake looked like: its color, shape and markings. This will help with your treatment.
  • Cover the bite with a clean, dry bandage.

What NOT to do if you get bitten by a snake:

  • Never apply ice to the snakebite or soak the wound in water.
  • Never cut the place that has been bitten.
  • Never try to suck the venom out of the snakebite.
  • Never apply a tourniquet or try to stop blood flow to or from the snakebite.
  • Never try to pick up or trap the snake.
  • Do not drink alcohol to relieve the pain of a snakebite.
  • Do not drink caffeinated beverages such as coffee or soda after you’ve been bitten by a snake.
