14 Central Texas Snakes To Look Out For

Snake! We know these slithery critters can spark fear in the hearts of many Texans. But, trust us, you don't need the shovel for these serpents. 

Snakes are wildly misunderstood. Some love 'em, some hate 'em. But, for everyone's safety, including your pet, you need to know about 'em.

As summer temperatures in Texas rise, reptiles like snakes become very common on park trails, near water, and even in your backyard garden. If you didn't see any on your last Hill Country hike, they were probably playing extreme hide and seek.

Here are 14 local Hill Country snakes that you should be on a first name basis with!

Local Venomous Snakes

First things first, let's debunk an old wives tale: juvenile snake venom is not more concentrated than adult snake venom. Neither--young or old--is more dangerous than the other. Both are not to be messed with.

Our Texas Hill Country venomous snakes are true warriors for our environment. Hunting rodents and small animals that can carry diseases make them an essential part of the ecosystem.

Expert Advice 

We asked snake expert, Gary Geiler (known as Serpentarian on Reddit) on the importance of Hill Country snakes.

"Every single species of snake is important to the environment. They have a greater purpose than just being beneficial to humans - they serve as food for other animals and keep populations of the animals they prey upon down. I am seeing more and more of this attitude lately where people enjoy and appreciate wildlife for what it is and not just what they get out of it."

What do I do if I see a snake?

Relax, back away slowly, and most importantly, whatever you do, do not call Pest Control.

Pro tip: Get out the water hose and gently spray the offending noodle until he starts to move on on his own - effectively reminding them that this location is undesirable.

Won't they bite me?!

In Serpentarian's words... "The truth is: trying to kill the snake is the number one way to get bitten by one. So all those granddads in the backyard who get the shovel out, actually raise the numbers of bites significantly."

If you are bitten, Texas Parks and Wildlife Department says stay calm and walk around if you can! Clean bite site with soap and water and remove tight fitting clothing or jewelry in case swelling should occur. 

Even if you haven't ID'd the species, call 9-1-1 and immediately transport to nearest medical facility for anti-venom treatment. Read more here!

How do I ID a snake?

Snap a picture (safely) and post to Reddit at r/whatsthissnake. This Reddit group has professional herpetologists that can recognize any snake in the world.

If you would like a snake relocated, please contact Austin Reptile Service. They also have a great snake ID page that can be filtered even by county.
