Snake Bites: What to Know
The thought of a snake bite is scary, but don’t panic—or try to suck out the venom. Knowing what to do can save a life, maybe even yours.
Are All Snakes Dangerous?
No. Only about 20% of U.S. snakes are venomous. Most bites aren’t fatal, but some can be serious without fast treatment.
Venomous Snakes in North America:
-
Rattlesnakes
-
Copperheads
-
Cottonmouths
-
Coral snakes
Pit vipers (like rattlesnakes) have triangle heads, slit pupils, and heat-sensing pits. Coral snakes look different—with round pupils and red, yellow, and black bands.
Symptoms
-
Nonvenomous bites: Pain, swelling, scratches—usually mild.
-
Venomous bites: Intense pain, swelling, bruising, nausea, trouble breathing, weakness. Coral snakes may cause drooping eyelids, tingling, or muscle weakness.
-
Dry bites: No venom injected, but still seek care.
Why It Matters
Most deaths are due to delayed treatment or allergic reactions. Recognizing symptoms early is crucial.
What to Do if Bitten:
-
Stay calm – Slows venom spread.
-
Call 911 – Get medical help fast.
-
Keep bite below heart level – Limit movement.
-
Remove tight items – Swelling happens quickly.
-
ID the snake if safe – A photo or description helps doctors pick the right antivenom.
