Whether you’re hiking through the woods, working in your garden, or exploring unfamiliar terrain, a snakebite can occur when you least expect it. While most snakes are non-venomous and pose little threat to humans, venomous species do exist, and a bite from one can be dangerous—or even life-threatening—if not addressed promptly. Knowing the signs of a snakebite and the correct first aid steps can make all the difference.

Recognizing the Signs of a Snakebite

Snakebite symptoms vary depending on the species of snake, the amount of venom injected, and the location of the bite. However, several common signs can help you identify if someone has been bitten and needs urgent attention:

1. Puncture Marks

Most venomous snakes have two prominent fangs, and their bites often leave two puncture wounds. These may be accompanied by smaller teeth marks from non-fanged teeth.

2. Pain and Swelling

Immediate and severe pain is a typical symptom, followed by swelling and redness around the bite site. The area may become tender, and swelling can spread quickly.

3. Discoloration and Blistering

Venom can damage surrounding tissue, causing bruising, a purplish or bluish tint to the skin, or blister formation.

4. Nausea and Vomiting

Systemic symptoms such as nausea, vomiting, dizziness, or weakness may begin within 30 minutes to a few hours after the bite.

5. Difficulty Breathing

In more severe cases—particularly with neurotoxic venom (like that from a cobra or coral snake)—victims may experience trouble breathing, blurred vision, or drooping eyelids.

6. Numbness or Tingling

Tingling or numbness in the fingers, toes, or mouth is another indicator of venom affecting the nervous system.

7. Abnormal Heart Rate or Blood Pressure

Some snake venoms can affect heart function, leading to rapid or irregular heartbeats and even a drop in blood pressure.

What to Do Immediately: First Aid for Snakebites

If you or someone you’re with is bitten by a snake, stay calm. Panic can cause the heart rate to increase, spreading venom more quickly through the body. Here’s what to do step by step:

1. Get to Safety

Move away from the snake to prevent additional bites. Do not attempt to catch or kill the snake. Your safety is the priority.

2. Call Emergency Services

Immediately dial emergency services or have someone take the victim to the nearest medical facility. Antivenom may be needed, and it’s only available in clinical settings.

3. Keep the Affected Limb Immobilized

Limit movement of the bitten area as much as possible. Keep it at or slightly below heart level. Movement accelerates venom spread, so immobilizing the area helps slow this process.

4. Remove Tight Items

Remove rings, watches, bracelets, or tight clothing near the bite area before swelling starts. Swelling can restrict circulation quickly.

5. Clean the Bite (But Don’t Flush with Water)

You can wipe the area gently with a clean cloth, but do not attempt to flush with water or apply alcohol or disinfectants.

6. Monitor Breathing and Heart Rate

Be alert for signs of shock or difficulty breathing. If the person becomes unresponsive, begin CPR if trained.

What Not to Do After a Snakebite

There are many outdated and dangerous myths about treating snakebites. Avoid these common mistakes:

• Do not apply a tourniquet. Cutting off blood flow can cause more damage.

• Do not suck out the venom. This can lead to infection and is largely ineffective.

• Do not cut the bite. It won’t help and can worsen the injury.

• Do not give the victim alcohol or caffeine. These can accelerate venom absorption.

• Do not apply ice. Ice may worsen tissue damage.

When to Seek Immediate Medical Attention

Always treat any snakebite as a potential medical emergency. Even if the snake is believed to be non-venomous, infection is still a risk. Prompt medical evaluation is essential for determining whether antivenom is necessary and to monitor for potential complications.

Preventing Snakebites

Prevention is always better than cure. Keep these safety tips in mind, especially if you live in or are visiting an area where venomous snakes are found:

• Wear boots and long pants in tall grass or wooded areas.

• Use a flashlight when walking outside at night.

• Do not reach into holes, under rocks, or in dense brush without checking.

• Leave snakes alone—many bites happen when people try to kill or move them.

• Keep your yard clean and free of debris where snakes might hide.
