It’s a beautiful afternoon in Texas. You’re gardening or letting the dog out, and suddenly you freeze. There’s a slithering movement in the grass. A snake.
Your heart rate spikes. Is it a harmless Rat Snake keeping the rodent population down? Or is it a venomous Copperhead waiting to strike?
In Texas, we coexist with over 100 species of snakes, but only about 15 are venomous. However, misidentifying them can be a painful—and expensive—mistake.
This guide will help you identify the “Big 4” venomous snake groups found in our state and tell you exactly what to do if you encounter one.

The “Big 4” Venomous Snakes in Texas
1. The Copperhead (The Master of Camouflage)
Copperheads are the most common venomous snake encountered in Texas suburbs (like Plano, Frisco, and The Woodlands). They blend in perfectly with dried leaves.
-
Key Identifier: Look for the “Hershey’s Kiss” pattern. Dark, hourglass-shaped bands on the sides of their tan body look like chocolate kisses.
-
Habitat: Wood piles, garden beds, and tall grass.
2. The Rattlesnake (The Warning System)
Most people know the sound, but you might not always hear the rattle before you see the snake.
-
Key Identifier: A triangular head that is much wider than the neck, and of course, the rattle at the end of the tail (though baby rattlesnakes may not have a rattle yet).

What To Do If You See a Snake
1. Stop and Back Away:
Do not try to kill it. Most snake bites happen when people try to kill or handle the snake. Give it space.2. Secure Pets and Children:
Bring dogs and kids inside immediately. Curious pets are the most frequent victims of snakebites.3. Identify from a Distance:
Take a picture if you can do so safely (zoom is your friend). You can upload this description to our AI Identification Tool for a quick check.4. Call a Professional:
If the snake is in your garage, on your porch, or near your children’s play area, do not wait for it to leave. It may be setting up a nest.Professional Snake Removal & Exclusion
