Texas Venomous Snakes
Texas is home to more venomous snake species than any other state. Ranch workers encounter snakes regularly while walking pastures, moving hay, working around old buildings, and clearing brush. Knowing how to respond to a snakebite can prevent panic and ensure the best possible outcome.

Recognizing a Venomous Snakebite
Pit Viper Bites (Rattlesnakes, Copperheads, Cottonmouths)
- Immediate pain at bite site
- Rapid swelling
- Bruising/discoloration
- Severe pain
- Nausea and vomiting
- Dizziness, weakness
- Metallic taste in mouth
- Tingling in mouth or extremities
- Difficulty breathing (severe cases)
Coral Snake Bites
- Weakness
- Drooping eyelids
- Difficulty speaking/swallowing
- Difficulty breathing
- Muscle paralysis
Dry Bites
- May have fang marks but minimal symptoms
- Still requires medical evaluation
- Can't assume it's a dry bite initially
Snakebite First Aid
Immediate Actions
- Get to a safe distance
- The snake may strike again
- Reassure the victim
- Sit or lie down
- Antivenom may be needed
- Hospital with snakebite experience is ideal
- In Texas: Call 1-800-222-1222 (Poison Control) for hospital guidance
- Remove boots if foot/ankle bitten
- Cut clothing if needed
- Minimize movement
- Splint if possible
- Movement increases venom spread
- Note the time
- Helps medical team track progression
- Do not scrub
- Cover loosely
What NOT to Do
- Apply a tourniquet
- Apply ice or cold packs directly
- Give alcohol
- Apply electric shock
- Use commercial "snakebite kits" with suction devices
- Catch or kill the snake (risk more bites)
- Drive yourself if bitten (symptoms may progress)
- Tourniquet: Can cause limb loss, doesn't help
- Ice: Causes additional tissue damage
- Suction devices: Studies show they're ineffective
If You're Alone
- Call 911 immediately
- Text location if voice communication difficult
- Move minimally toward help/road
- Stay on phone with dispatcher
- Signal for help (horn, whistle)
Medical Treatment
What Happens at the Hospital
- Monitor vital signs
- Track swelling progression
- Blood tests for clotting function
- Pain management
- Wound care
- Tetanus prophylaxis
- Monitoring (often 24+ hours)
Antivenom
- Derived from sheep or horse antibodies
- Multiple vials may be needed
- Allergic reactions possible but manageable
- Progressive swelling
- Signs of systemic effects
- Abnormal blood clotting tests
Coral Snake Antivenom
- Specific antivenom for coral snakes
- May be given preventatively (symptoms delayed)
- Can be in short supply
Prevention
Reducing Snakebite Risk
- Don't put hands where you can't see
- Use a flashlight at night
- Wear proper footwear
- Long pants
- Leather gloves when moving debris
- Gaiters for extra protection
- Common around old buildings, junk piles
- Near water sources (cottonmouths)
- Active in warm weather (spring through fall)
- May be sluggish but still dangerous in cooler weather
- Remove brush and debris piles
- Close gaps under buildings
- Reduce rodent populations (snake food source)

Special Situations
Bites to Face or Torso
- Faster venom absorption
- Airway at risk with facial bites
- Keep calm
- Rapid transport essential
- Monitor airway closely
Bites to Dogs or Livestock
- Horses and cattle can be bitten
- Contact your veterinarian immediately
- Carry if possible (don't let them walk)
- Get to vet quickly
- Antivenom available for dogs
Multiple Bites
- More aggressive treatment needed
- Same first aid principles
Children
- More serious potential complications
- Same first aid, urgent transport
Texas-Specific Resources
Hospital Selection
- Some rural hospitals may need to transfer
- Poison Control can advise on best facility
Poison Control Partnership
- Help identify snake if possible
- Hospital recommendations
- Treatment guidance for medical teams
Recovery from Snakebite
What to Expect
- Multiple doses of antivenom possible
- Blood tests to monitor clotting
- Follow-up appointments needed
- Watch for signs of serum sickness (delayed reaction to antivenom)
- Some have long-term symptoms at bite site
Serum Sickness
- Fever, joint pain, rash
- Treatable with steroids
- Notify your doctor
Bottom Line
- Stay calm - Panic worsens outcomes
- Get away from the snake - Don't try to catch or kill it
- Call 911 or go to ER - Every venomous bite needs medical evaluation
- Remove jewelry - Before swelling makes it impossible
- Immobilize the limb - Keep at or below heart level
- Mark the swelling - Helps track progression
- Don't cut, suck, or tourniquet - These are harmful
- Time matters - But even delayed treatment helps
- Prevention works - Watch where you step and reach
- Texas has antivenom available - Modern treatment saves lives
