Sizes of Florida’s Largest Spiders

Florida is home to a variety of spider species, some of which can grow to impressive sizes. Let’s take a closer look at some of the largest spiders you might encounter in the Sunshine State:

Huntsman Spider

The Huntsman Spider, scientifically known as Heteropoda venatoria, is one of the largest spiders found in Florida. These arachnids can reach leg spans of up to 12 inches, making them quite intimidating.

However, despite their size, Huntsman Spiders are generally non-aggressive and prefer to retreat rather than confront humans. They can often be found hiding in dark corners of buildings or under tree bark.

Golden Silk Orbweaver

The Golden Silk Orbweaver, also known as Nephila clavipes, is another impressive spider species found in Florida. While not as large as the Huntsman Spider, Golden Silk Orbweavers can still grow to have leg spans of around 4-5 inches.

These spiders are known for their intricate golden silk webs, which can span several feet in diameter. Despite their intimidating appearance, Golden Silk Orbweavers are not considered dangerous to humans and play an important role in controlling insect populations.

Fishing Spider

The Fishing Spider, scientifically known as Dolomedes spp., is a common sight near bodies of water in Florida. These spiders are known for their ability to walk on water, thanks to the tiny hairs on their legs that trap air bubbles.

Fishing Spiders can grow to have leg spans of up to 3-4 inches, making them one of the larger native spider species in the state. They primarily feed on small aquatic insects and are not a threat to humans.

Giant Lichen Orbweaver

The Giant Lichen Orbweaver, scientifically known as Araneus bicentenarius, is a fascinating spider species found in Florida. These spiders are known for their vibrant colors and unique patterns, which help them blend in with their surroundings.

While not as large as some of the other spiders on this list, Giant Lichen Orbweavers can still grow to have leg spans of around 2-3 inches. They are harmless to humans and play a crucial role in maintaining the balance of ecosystems.

Florida Wandering Spider

The Florida Wandering Spider, scientifically known as Phoneutria boliviensis, is a rare and elusive spider species found in the state. These spiders are known for their venomous bite, which can cause severe pain and discomfort.

While they are not as large as some of the other spiders on this list, with leg spans of around 2-3 inches, their venomous nature makes them worth mentioning. It’s important to exercise caution if you come across a Florida Wandering Spider and to seek medical attention if bitten.

Remember, while these spiders may look intimidating, they play important roles in Florida’s ecosystems by controlling insect populations. It’s always best to observe them from a safe distance and appreciate the wonders of nature.

Where Big Spiders are Found in Florida

Florida is known for its diverse wildlife, and that includes spiders. These eight-legged creatures can be found in various habitats throughout the state. If you’re curious about where the big spiders are found in Florida, here are some common locations to keep an eye out for:

Under Rocks and Debris

One of the most common places to find big spiders in Florida is under rocks and debris. Spiders like to hide in dark and sheltered areas, and these spaces provide the perfect hiding spot. When you’re exploring nature trails or even your own backyard, don’t forget to lift up rocks or check under fallen branches – you might just come across a big spider!

In Trees and Shrubs

Another popular habitat for big spiders in Florida is in trees and shrubs. These arachnids are skilled climbers and can often be found spinning their intricate webs high up in the branches. If you’re hiking or strolling through a park, take a moment to look up and admire the impressive webs these spiders create.

Near Water Sources

Spiders need water to survive, so it’s no surprise that they can often be found near water sources in Florida. Whether it’s a pond, marsh, or even just a small puddle, spiders will take advantage of the moisture in the air and the abundance of insects that are attracted to water.

So, if you’re near a body of water, keep an eye out for big spiders lurking nearby.

In Old Sheds and Barns

Old sheds and barns provide the perfect shelter for big spiders in Florida. These structures offer dark and undisturbed environments that spiders love. If you’re exploring a farm or an abandoned property, be cautious when entering old sheds or barns, as you might encounter some impressive arachnids.

Around Home Foundations

Lastly, big spiders can often be found around home foundations in Florida. The cracks and crevices in the foundation provide ideal hiding spots for spiders. While they may not be harmful, they can startle unsuspecting homeowners.

If you’re working in the garden or doing maintenance around your house, keep an eye out for these eight-legged guests.

Remember, while big spiders may look intimidating, most of them are harmless. They play an essential role in maintaining the balance of ecosystems by controlling insect populations. So, the next time you come across a big spider in Florida, take a moment to appreciate its beauty and importance in the natural world.

Why Large Spiders Thrive in Florida

Florida is home to some of the largest spiders you can find. Several factors contribute to the thriving spider population in this state.

Warm, Humid Climate

The warm and humid climate of Florida provides the perfect environment for spiders to grow and reproduce. Spiders are ectothermic animals, meaning their body temperature is regulated by the surrounding environment.

In the hot and moist conditions of Florida, spiders can thrive and reach their maximum size.

No Hard Freezes

Unlike many other regions, Florida rarely experiences hard freezes. This lack of extreme cold temperatures allows spiders to survive throughout the year and continue to grow. In colder areas, spiders may not be able to survive the winter, limiting their size and population.

Plentiful Insect Prey

Florida’s diverse ecosystem is home to a wide variety of insects, which serve as a bountiful food source for spiders. With an abundance of prey available, spiders can grow larger and stronger. The presence of insects also attracts spiders to areas with high insect activity, further contributing to their size.

Lack of Natural Predators

Florida has a relatively low population of natural predators that feed on spiders. While birds and some reptiles may prey on spiders, their numbers are not enough to significantly control the spider population. This lack of natural predators allows spiders to thrive and reach larger sizes.

Old Buildings and Tree Canopies

Old buildings and tree canopies provide shelter and ideal habitats for spiders. These structures offer protected spaces where spiders can build their webs and find prey. As a result, spiders in Florida have ample opportunities to grow and develop in these favorable environments.

Spider Bite Risks and Safety Tips

Florida is known for its diverse wildlife, and spiders are no exception. With the warm and humid climate, it’s no surprise that spiders thrive in the Sunshine State. But just how big do spiders get in Florida, and what risks do their bites pose to humans?

Let’s explore spider bite risks and some safety tips to keep in mind.

Most Spider Bites are Minor

The good news is that the majority of spider bites in Florida are minor and cause little harm. Most spiders found in the state are not venomous and their bites typically result in mild symptoms such as redness, itchiness, and slight swelling.

In fact, many spider bites go unnoticed or are mistaken for other insect bites. However, it’s important to keep an eye on any bite and seek medical attention if symptoms worsen or persist.

Venomous Species to Watch For

While most spider bites in Florida are harmless, there are a few venomous species that residents and visitors should be aware of. The most notable is the black widow spider, known for its distinctive red hourglass marking on its abdomen.

Black widow bites can cause severe pain, muscle cramps, and other systemic symptoms. Another venomous spider to watch out for is the brown recluse, which can cause necrotic skin lesions.

Signs of a Dangerous Bite

It’s important to be able to recognize the signs of a potentially dangerous spider bite. If you experience severe pain, muscle cramps, difficulty breathing, or any other unusual symptoms after being bitten, it’s crucial to seek immediate medical attention.

These symptoms could indicate a venomous spider bite and require prompt treatment.

First Aid for Bites

If you or someone you know is bitten by a spider, there are some steps you can take to provide first aid before seeking medical help. First, wash the affected area with mild soap and water to reduce the risk of infection. Applying a cold compress or ice pack can help reduce swelling and pain.

Avoid scratching the bite, as this can lead to further irritation and potential infection.

Tips for Staying Safe

To minimize the risk of spider bites, it’s important to take precautions. Here are some tips for staying safe:

  • Keep your surroundings clean and clutter-free, as spiders are attracted to dark and undisturbed areas.
  • Seal cracks and crevices in your home to prevent spiders from entering.
  • Wear long sleeves, pants, and gloves when working in areas where spiders are likely to be present, such as garages or sheds.
  • Shake out shoes, clothing, and bedding before use to ensure there are no spiders hiding.
  • Use insect repellent that is effective against spiders when spending time outdoors.
  • Teach children to avoid touching spiders and to report any bites or unusual encounters.

By following these safety tips and being aware of the types of spiders in Florida, you can greatly reduce the risk of spider bites and enjoy the beautiful state without worry.

Giant Spider Myths and Misconceptions

Myth: Spiders Infesting Bananas

One common myth about spiders in Florida is that they infest bananas. This myth may have originated from the fact that some spiders, like the Brazilian wandering spider, are known to hide in banana shipments.

However, it is highly unlikely to find spiders infesting bananas in your local grocery store. The chances of encountering a spider in a banana bunch are extremely rare. So, you can enjoy your bananas without any fear of finding eight-legged creatures crawling out of them!

Myth: Spiders Laying Eggs Under Skin

Another popular myth is that spiders in Florida lay eggs under people’s skin. This notion likely stems from the fear of spiders and their ability to bite. However, spiders do not lay eggs under human skin. In fact, most spiders prefer to lay their eggs in protected areas such as webs or burrows.

So, rest assured that you won’t wake up with a spider colony growing beneath your skin!

Myth: Spider Raining from the Sky

One of the more bizarre myths is the belief that spiders can rain down from the sky in Florida. While it is true that some spiders, like the ballooning spiders, can disperse by floating through the air using their silk threads, it is highly unlikely to witness a spider rainstorm.

Spiders are generally too heavy to be carried by the wind for long distances. So, you don’t have to worry about getting caught in a spider downpour during your Florida vacation!

Myth: Spiders as Big as Dogs

A recurring myth that often circulates is the idea that spiders in Florida can grow to be as big as dogs. While Florida is home to several large spider species, such as the golden silk orb-weaver, they do not reach the size of dogs.

The average size of spiders in Florida varies depending on the species, but none come close to the size of a small dog. So, you can breathe a sigh of relief knowing that you won’t encounter any arachnids of that magnitude!


While a few spider species in Florida can reach sizes of 5 inches or more, the majority stay well under 1 inch long. And there’s no evidence for mythical giant spiders the size of dinner plates. With proper education and basic precautions, even the largest spiders in Florida pose minimal risks to humans. So next time you spy a large arachnid while exploring the Sunshine State, there’s no need to panic. Simply appreciate these fascinating creatures from a distance as part of Florida’s unique biodiversity.
