FAQ: Texas Backyard Snakes
What should I do if I find a snake in my yard?
First, identify it from a safe distance. If it is non-venomous, leave it alone — it will move on. If it is venomous or you cannot identify it, keep pets and children away and call a professional snake removal service.
Are Texas Rat Snakes dangerous?
No. Texas Rat Snakes are non-venomous constrictors. They are beneficial because they eat rodents. They can be defensive if cornered and may bite, but their bite is harmless (like a cat scratch).
