Thursday, July 16 is World Snake Day — a good moment to learn who’s slithering through your yard, why most of them are working for you, and how to keep everybody safe when a rattlesnake shows up on the back porch

Well neighbor, let’s talk about the animal in Texas that gets the worst PR of any critter alive. Snakes. Most folks hear the word and their skin crawls. But here’s a truth worth carrying into World Snake Day on July 16: Texas is home to more than 105 species and subspecies of snakes, and according to Texas Parks and Wildlife, only 15 of those are considered potentially dangerous to humans. That means the vast majority of snakes you’ll ever see in your yard, along a hiking trail, or curled up under a porch step aren’t out to hurt you — and quite a few of them are actively working in your favor.
So today we’re going to walk through what’s out there, why they matter, and — because this is Texas and rattlesnakes do exist — the practical safety tips every family should know. The goal isn’t to make you love snakes. It’s to help you respect them, recognize them, and share the state with them without anybody getting hurt.
Why snakes matter more than you think
Here’s the thing worth remembering next time one turns up in the garden. Snakes are some of the best free pest control money can’t buy. They keep rat and mouse populations in check, which matters both for public health and for anybody who’s ever had rodents chew through wiring in the barn. They eat slugs and small insects that damage gardens. They dig burrows that other species use for shelter. And they’re a critical part of the food chain, feeding hawks, owls, coyotes, and other predators.
Texas Parks and Wildlife puts it plainly on their own guidance: “Snakes serve a valuable function in the environment. Please do not kill a snake — even a venomous one.” That advice comes straight from the state’s wildlife biologists, and it’s worth taking seriously. The truth is that snakes don’t hunt humans. They don’t chase people. When you leave one alone, it will almost always retreat. Most bites in Texas happen when people try to handle, capture, or kill a snake themselves.
Who’s likely in your yard
For most Texans, the snakes you’re actually seeing are harmless. In the San Antonio area, for example, the checkered garter snake is a common yard and garden visitor — a nonvenomous, small, striped snake that helps control mice, slugs, and other small pests. Rat snakes are common statewide and are exactly what they sound like — expert rodent hunters. Coachwhips, ribbon snakes, and hognose snakes are all nonvenomous and beneficial. If you spot one, take a breath, back off, and give it space. It’ll move on.
The 15 to know about
Now let’s talk about the ones that deserve caution. Texas has two broad groups of venomous snakes: pit vipers and coral snakes.
Pit vipers include three families you’ve probably heard of. Copperheads have chestnut or reddish-brown crossbands on a lighter body and are found across much of Texas, especially in wooded areas, near creeks, and in overgrown vacant lots. Their bite is rarely fatal because of relatively short fangs and small venom amounts, but it still needs medical care. Cottonmouths, sometimes called water moccasins, are the world’s only semi-aquatic viper. They live near ponds, swamps, and slow-moving water, mostly in East and Central Texas. They’re dark brown, olive, or nearly black, often marked with wide bands. Rattlesnakes are the largest group — Texas has 10 different species of them. The western diamondback is by far the most common and widespread, found in nearly every part of the state except the far east. Look for brown, diamond-shaped markings down the back and alternating black-and-white rings on the tail. It can grow to seven feet.
Coral snakes are the other venomous group, and they’re the ones with the famous rhyme every Texas kid should learn: “Red next to black — friend of Jack. Red next to yellow — kills a fellow.” Coral snakes have bright red, yellow, and black bands that completely encircle the body, yellow touching red. Harmless lookalikes like scarlet snakes and milk snakes have similar colors, but their bands don’t fully wrap around, and their red touches black, not yellow. Coral snakes are shy and rarely bite, but their venom is potent — so learn the pattern, and give them wide berth.
Simple habits that keep everybody safe
Here’s the practical part. Most Texans coexist with snakes their entire lives and never have a problem, because a few basic habits go a long way. Wear closed shoes when you’re outside — flip-flops in the yard are asking for trouble. Never put your hands somewhere you can’t see, and that includes reaching into brush piles, under wood pallets, into animal burrows, or over rocks and fallen logs. Step on logs, never over — take a look at the other side first. Use a flashlight anywhere you walk at night, even in your own yard. Keep the lawn trimmed, and move brush, wood, and rock piles as far from the house as you can. Those piles make ideal shelter for snakes and for the rodents that draw them in.
If you’re out hiking, wear sturdy boots, watch your step near rocky ledges, creek banks, and underbrush, and don’t reach into crevices. If you spot a snake, freeze. Let it see you and give it a chance to move away — which it almost always will. Back away slowly and go around. Don’t try to catch it, kill it, or take a selfie with it.
If a bite happens
Snake bites in Texas are rare — statewide, roughly one to two people die from venomous snakebites per year on average, fewer than are killed by lightning strikes each year. But if a bite does happen, the response matters. Call 911 immediately. Stay calm and try to limit movement. Keep the bitten limb at or below heart level. Remove any tight jewelry, watches, or rings near the bite, since swelling can come on fast. Do not cut the wound, do not try to suck out the venom, do not apply ice, and do not use a tourniquet. Every one of those old-timer remedies makes outcomes worse, not better. Get to a hospital as quickly and calmly as possible. Texas hospitals stock antivenom for pit viper bites, and modern first aid and medical care are why fatal bites have become so uncommon in this state.
A note on one snake it’s actually illegal to harm
Worth mentioning: the timber rattlesnake, sometimes called the canebrake rattlesnake, is a threatened species in Texas and is illegal to kill or harm. It lives in the eastern third of the state in wooded bottomlands. If you spot one, back away and leave it alone — not just because it’s the right thing to do, but because harming it is against the law.
Meet your neighborhood snakes
Here’s a small assignment for World Snake Day, neighbor. Take a few minutes to learn the common snake species in your part of Texas. Texas Parks and Wildlife has excellent free identification guides on their website, and Texas A&M AgriLife Extension publishes a full color guide to distinguishing venomous from nonvenomous species with clear photos. Print one out and stick it on the fridge. Show it to the kids. It’s a genuinely useful skill, and it’ll take the fear down a notch the next time something long and slithery crosses the driveway.
Snakes have been part of the Texas landscape for a lot longer than any of us have been walking it. This July 16, take a moment to appreciate the quiet, unglamorous work they do — controlling rodents, feeding hawks, keeping the ecosystem in balance — and give them the respect and the space they’ve earned. And if one shows up on the porch, remember: freeze, back away, leave it alone. It’s just passing through.
Happy World Snake Day, neighbor. Wear your boots.
