Difference Between Tarantulas, Ground Spider & Cellar Spiders

Hey there, brave souls and curious minds! So, you walked into a room, saw a spider lurking in the corner, and felt your skin crawl, huh? Yeah, I’ve been there. But hold on a sec—let’s not put all spiders in the same “nope” basket. Whether it’s the hulking tarantula, the quick-footed ground spider, or the spindly cellar spider, each of these arachnids has its own unique charm. In this blog, we’re diving deep into what sets them apart from each other. So grab your adventurer’s hat, and let’s unravel this web!

Tarantulas— The Heavyweights of the Spider-World

Tarantulas Spider


When you hear the word ‘tarantula,’ what comes to mind? King Kong of spiders? Well, you’re not far off. These bad boys can get as big as your palm! They usually hang out in warm climates and love to play hide and seek in burrows or tree hollows.

Unique Features

Let’s get up close and personal (well, not too close). Tarantulas are basically the teddy bears of the spider world. No, really—they’re hairy! These guys come in a variety of colors, from muted browns to vibrant blues. Oh, and if they’re ticked off? They can flick urticating hairs from their abdomen as a defense mechanism. It’s like their version of throwing confetti, only a lot less fun for us.

Common Myths Busted

Alright, let’s tackle the elephant in the room. Or should I say the tarantula? Despite their Hollywood villain status, they’re generally not venomous enough to be life-threatening to humans. In fact, their bite might be less painful than a bee sting! So much for the horror flicks, eh?

Human Interaction

Believe it or not, some folks keep these big furballs as pets! They’re generally easy-going and low-maintenance—kind of like that roommate you got along with in college.

Ground Spiders — The Sprinters Among Spiders

Ground Spiders


Enough about the gentle giants; let’s talk about the roadrunners of the spider realm: ground spiders. These guys are usually smaller and love to scurry around on, well, the ground. You’ll find them hiding under rocks, leaves, or your misplaced laundry.

Unique Features

What sets ground spiders apart? Speed, baby! These little racers don’t build webs to catch their prey. Instead, they rely on their agility and quick reflexes. Plus, they’ve got this knack for blending into their surroundings, like tiny ninjas.

Common Misconceptions

So you found a quick, little spider and you’re convinced it’s some lethal variety? Pump the brakes! Most ground spiders are harmless to humans. Their venom usually isn’t strong enough to do more than give you a mild irritation.

Human Interaction

Ground spiders are the introverts of the arachnid world. They prefer not to engage and will usually bolt if you so much as breathe in their direction. Can’t blame them, right?

Cellar Spiders — The Long-Legged Dancers

Cellar Spiders


Let’s shimmy our way over to the cellar spiders, shall we? You’ve likely seen these guys in the forgotten corners of your basement, attic, or even behind your bathroom mirror. They’re pretty small but make up for it with their long, graceful legs.

Unique Features

What’s really cool about cellar spiders? When they feel threatened, they shake their webs like they’re dancing to some invisible beat. It’s a defense mechanism designed to blur their outline, and frankly, it’s pretty neat to watch.

Common Misconceptions

Alright, let’s clear the air. These spiders are not “daddy long legs,” even though folks often get the two mixed up. And that myth about them having super potent venom? Hogwash. They’re about as dangerous as a rubber duck.

Human Interaction

Honestly, cellar spiders keep to themselves. They don’t mind us and can actually be helpful by nabbing other pesky insects in their webs. So, they’re like the friendly neighborhood watch—just with more legs.

Side-by-Side Comparison

So, who wins the Spider Olympics? Let’s break it down:

Side-by- Comparison of Spiders

Size: Tarantulas take the gold here. Ground spiders are more middle-of-the-road, and cellar spiders bring up the rear with their tiny bodies.

Habitat: Tarantulas like it warm and cozy; ground spiders prefer the great outdoors; cellar spiders opt for your home’s nooks and crannies.

Venom Potency: Mostly a draw. None of these guys have venom that’s lethal to humans.

Now, just for kicks: if you were a spider, which one would you be? The laid-back tarantula, the speedy ground spider, or the elegant cellar spider?


Okay, take a deep breath; we’re at the finish line. Look, spiders may give us the heebie-jeebies, but they’re not all cut from the same cloth. From the teddy-bear-like tarantulas to the agile ground spiders, to the graceful cellar spiders, these creatures are as varied as they come. So the next time you see a spider and feel the urge to run screaming, take a moment to identify it. Who knows, it might just turn out to be your next eight-legged friend!


Q: Are tarantulas poisonous to humans?

Answer: Great question! The short answer is no, not really. While they do have venom, it’s usually not strong enough to be dangerous to humans. A tarantula bite might hurt a bit, but it’s often compared to a bee sting. So no need to freak out if you see one!

Q: Can ground spiders bite?

Answer: Yep, they can, but they usually won’t unless they feel cornered. Even then, their venom is not a big deal for humans. You might get a bit of redness or itching, but that’s about it. They’re more scared of you than you are of them!

Q: What’s the deal with cellar spiders shaking their webs?

Answer: Ah, the spider dance! When threatened, cellar spiders shake their webs to blur their outline and confuse predators. It’s like their version of breakdancing for survival. Pretty cool, huh?

Q: Do tarantulas make good pets?

Answer: Believe it or not, yes! Tarantulas are generally low-maintenance and easy-going. They don’t require daily walks or constant attention, so they’re perfect for folks who want a unique pet without the hassle

Q: How can I get rid of ground spiders in my garden?

Answer: First off, ground spiders are actually good for gardens since they eat other pests. But if you really want them gone, try removing hiding spots like rocks and leaves. You can also use natural repellents like citrus peels. Just know that they’re doing you a favor by being there!

Q: Are cellar spiders the same as daddy’s long legs?

Answer: Nope, they’re not the same thing, although people often get them mixed up. Daddy Long Legs are actually not true spiders; they belong to a different order of arachnids. Cellar spiders are the real deal with their spindly legs and cobweb homes.

Q: How do I differentiate between a ground spider and other dangerous spiders?

Answer: Good eye! Ground spiders are often mistaken for more dangerous types. The key is to look at their behavior and features. Ground spiders are fast, have a flattened body shape, and don’t spin webs for hunting. If you’re ever in doubt, it’s best to consult an expert.

Q: Can I find tarantulas in the U.S.?

Answer: You bet! Some species of tarantulas are native to the southern and southwestern parts of the U.S. So if you’re on a road trip in those areas, keep your eyes peeled!
