There's a snake.

Take a breath. Most Texas snakes are nonvenomous, help control rodents, and would rather avoid you. The venomous snakes fall into four groups: copperheads, cottonmouths, rattlesnakes, and coral snakes. You do not need a close look to make a safe choice - give any unknown snake room.

The four venomous types

Do not wait for swelling or other symptoms. A suspected venomous bite needs prompt medical care, even when the person feels all right at first.

Copperhead

Tan with darker hourglass-shaped bands. Often well camouflaged in leaves and brush.

Cottonmouth (water moccasin)

Dark and thick-bodied, near water in the eastern half of the state; shows a white mouth when threatened.

Rattlesnakes

Several kinds (the western diamondback is the big one). Usually - not always - they buzz a warning.

Coral snake

Small, brightly ringed, and usually shy. Do not rely on a color rhyme or handle one for a closer look.

Don't trust the old shortcuts. A triangular head, narrow pupils, a heavy body, or a color rhyme can all mislead you. The safe rule is simpler: leave any snake you cannot identify from a distance alone.

If someone is bitten

Do this

  • Move away from the snake and stay calm.
  • Keep the bitten area still and about level with the heart.
  • Call 911 or Poison Control at 1-800-222-1222 right away, and get to an ER - antivenom works.
  • Take off rings, watches, and tight clothing near the bite before it swells.
  • If you can do it safely, note the snake's color and pattern (a phone photo from a distance is plenty) so doctors can match the antivenom.

Do NOT

  • Don't cut the bite or try to suck out venom.
  • Don't use a tourniquet or pack it in ice.
  • Don't give medicine unless Poison Control or a clinician tells you to.
  • Don't try to capture or kill the snake - even a dead snake can bite by reflex for a while.

Those old "remedies" - cutting, sucking, ice, tourniquets - cause harm. Skip them and get to a hospital.

Keeping snakes away

Snakes follow food and shelter. Clear brush, woodpiles, rock piles, tall grass, and junk near the house, and watch your hands and feet around rocks, logs, and sheet metal. A snake in the yard will usually move on if you give it space; for one stuck in a garage or house, call a local wildlife removal pro. Most snakes are nongame (you'd need a hunting license to kill one, and a few species are specially protected) - and even a harmless bite can get infected, so don't handle wild snakes.
