Tips to Prevent Snake Bites
DO NOT tease or try to capture or handle a venomous snake.
Always be aware of your surroundings.
Walk in areas where the ground is clear so you can see where you step.
Wear protective clothing, such as long pants and hiking boots.
Wear gloves when using your hands to move brush or rocks.
Never put your hands or feet into places you cannot see.
Patch holes in your home that are more than a 1/4 inch wide.
If you encounter a snake, don't panic or blindly run away without looking carefully where you are going.
First Aid for Snake Bites
- Get to a hospital immediately. The only accepted treatment is the appropriate serum, or antivenin, administered by a medical professional. If the trip is a long walking distance, send someone for help.

- Remain calm. Activity speeds your heart rate and your metabolism, which increases the rate the venom spreads through your body.
- Put a safe distance between you and the snake. Do not attempt to capture the snake.
- Remove rings, watches, and bracelets from around the bite area.
- Keep the bite area immobilized and level with your heart.
- Carry a cell phone to call the New Mexico Poison Center at 1-800-222-1222 for help.
- DO NOT use a tourniquet or any other local treatment
- DO NOT use the "cut-and-suck" method
- DO NOT use ice on the bite
