The 6 Biggest Spiders You’ll Encounter in Florida

Do you know what the biggest spiders in your area are? If you’re thinking about living in Florida, then it’s important to know that there are a lot of big spiders on the loose! This post is going to introduce you to six of the most common and largest types of spider found in Florida, so read on.

It isn’t as simple as it sounds to choose the largest Florida spider. There are many ways to judge the size of a spider. Three factors can help determine the size of a spider. These are:

  • The size of the body
  • The length of its leg span
  • The body’s weight

I’ve listed six spiders below that are commonly considered the largest in Florida, taking into account all of these factors.

1. Huntsman spiders

Huntsman spiders

The Huntsman spider is an invasive species that originated in Asia. These spiders are also known as the giant crab spider and can be found in the south of the state where the climate is favorable. The Florida type, Heteropoda veneatoria, has a length of about an inch and a length of up to five inches. Like many spiders the males are bigger than the females.

This spider is similar to the wolf spider in that it doesn’t build webs. It relies on speed and strength of its jaws for hunting and killing its prey. Their bite can be quite venomous but is not considered to be medically important. It causes only mild pain.

Quick facts

These are often found in Florida.

Grows up to five inches long, typically one inch or less.

Males and females can be different sizes but males usually bigger than the female. Huntsman spiders don’t build webs- they rely on their speed for hunting prey. The male’s bite is venomous and painful but not a major medical issue like some other species of spiders, such as black widows.

2. Daddy Long Legs

Daddy Long Legs

Two different species of arachnids are known as “daddy-long legs”. They have very short legs and small bodies. These are the Harvestmen (Opiliones), and cellar spiders, (Pholcidae). These are two distinct species that many people have difficulty identifying.


Although they look like spiders, harvestmen are not actually spiders. They are closer to scorpions and mites than to spiders. They are small in size, but have huge legs.

Cellar Spiders

Cellar spiders are also small in size and have long legs, making them easy to confuse with Harvestmen. This spider is, however, not a Harvestman. They can grow up to 2 inches in length.

Urban Legend

Both cellar spiders and harvestmen are harmless. Despite this fact, there is an urban legend that daddy longlegs are the most dangerous animals on the planet. However, their fangs are too small for humans to cut. This urban legend is not true. Because neither Harvestman nor cellar spiders possess venom glands.

Quick facts

Daddy long legs are not spiders, but arthropods. They look like daddy-long-legs and don’t have venom glands.

Harvestmen also resemble some cellar spider species in size and leg length, which is why they can be confused with one another.

Both harvestmen and cellar spiders lack the ability to inject a human with even mild poison when bitten due both their tiny fangs.

3. Widow Spiders

Widow Spiders

Florida is home to four types of widow spiders. These four species are:

  • Southern Black Widow
  • Northern Black Widow
  • Brown Widow
  • Red Widow

The male widow is usually 1.5 inches larger than the female, and her size includes her legs. The widow’s bite is stronger than the others on the list. If you are bitten, it is important to seek medical attention immediately. Only the widows are dangerous. Males are not considered to have enough venom to make them medically important.

Because they live in areas where there is a lot of traffic, the southern black widow and brown widow are the most common. The panhandle region of Florida is home to the northern black widow, which builds its web on low-hanging tree branches. The red widow spider, on the other hand, prefers to burrow under objects and scrub.

The male is the widow spider’s prey after mating. This is how the name “Witness Spider” was given. Scientists believe that the female eats the male after mating to provide protein for her young. This may explain why the average life expectancy of a female widow is three years. A male widow lives only one to two months.

What happens if you are bitten by a Widow Spider

Although widows are feared for their reputation, you will not be bitten by these venomous insects. Venomous spider bites are more common in children and elderly, but you should not be concerned about them. You will likely only experience these symptoms:

Widow Bite Symptoms

  • Extreme pain
  • Headache
  • Abdominal cramps and muscle spasms
  • Nausea
  • Tremors and convulsions
  • Excessive sweating
  • The bite area is prone to lesions
  • Vomiting
  • Unconsciousness

No matter how severe the symptoms seem, call 911 immediately if you feel like you have been bitten by a widow. To reduce the spread of the venom through your bloodstream, it is important to stay calm and not to use a tourniquet. To ensure an accurate identification, capture the spider if you are able to. To reduce swelling and ease pain, use a cool, damp cloth between the time you are bitten and the time you consult a doctor.

What is the most venomous spider in Florida?

Florida has many spiders that are considered to be the most dangerous. These are the contenders for the title:

  • Northern Black Widow
  • Southern Black Widow
  • Brown Widow
  • Red Widow
  • Brown Recluse

Quick facts

Widows are notorious for their neurotoxic venom. Widows’ bites can cause severe pain, abdominal cramping and muscle spasms, excessive sweating and tremors or convulsions that may lead to death if not treated within 12 hours.

Male spiders typically die after mating with a female spider because she usually eats him – this is known as “witnessing.”

4. Black and yellow Argiope Spider

Argiope Spider

The black-and-yellow argiope ( Aurantia), also known by the writing spider, is up to one inch in size. It can be identified easily by its distinctive silver carapace with yellow-and-black markings and its distinctive silver carapace. You can find this spider in the woods near the edges of forests. It is easily identified by its large, zigzag web. The webs of Argiope spiders are usually hung upside-down. These spiders are blind and cannot see well. They navigate using vibrations in their web’s threads. These spiders are able to attract female mates through vibrating and plucking the threads.

Argiope venom can be mildly toxic, but it is not considered to be of medical significance. You can compare it to a bee bite, which causes some swelling and redness. The spider bites only when it feels threatened or cornered.

Quick facts

Argiope spiders are not dangerous to humans. They can cause a little swelling and redness at the site of the bite.

There is no need for medical attention unless you experience symptoms from Argiope’s venom, which would include pain in your abdomen or cramps followed by vomiting.

Males die after mating with females because they’re usually eaten by them – this process is known as “witnessing.”

5. Wolf Spider

Wolf Spider

The large, hairy spiders that are found in Florida are a common problem for people with arachnophobia. Although they can grow to as large as two inches, their thick legs and heavy bodies can make them seem larger. The Hogna lenta wolf spider (Hogna lenta), has a heavy body and thick legs. They can be found crawling along walls, both inside and out of buildings.

Wolf spiders do not build webs. They can run at incredible speeds and use their speed to catch their prey. Cockroaches are their main food source.

Although these spiders can bite quickly if they feel threatened or afraid, their bite isn’t considered to be dangerous. The bite can be quite painful and cause swelling. The fangs can also puncture the skin occasionally. Although wolf spiders come in a variety of colors, they are often mistaken for more dangerous brown recluses.

Quick facts

Wolf spiders are not dangerous to humans. They will only bite if they feel threatened or cornered.

The pain from a wolf spider’s bite can be quite painful and cause swelling at the site of the bite, but it is considered non-toxic in both young children and adults.

Bites may also puncture skin occasionally, which could lead to infection if left untreated.

6. Golden Silk Orb-Weaver

Golden Silk Orb-Weaver

The golden orb-weaver (Nephilaclavipes), is sometimes called a banana spider by Floridians. It is best known for its striking coloration and impressive webs. Although this species’ males are small (1/4 inches), the females are typically less than three inches in size (including their legs).

The golden silk orb weaver is a brightly-colored spider that has yellow and black stripes on its legs. They are excellent web spinners and have been known to create their tri-dimensional, orb-shaped webs from yellow silk in wooded areas. These spiders are large and brightly colored. Their venom is harmless to healthy adults, except if the victim gets infected by the bite or has an allergic reaction.

The harmless orb-weaver is sometimes called a banana web spider. However, it should not be confused the more dangerous and aggressive Brazilian banana spider.

Quick facts

The golden silk orb-weaver is not dangerous to humans. Their venom is harmless and cannot harm healthy adults, but when a victim gets infected by the bite or has an allergic reaction, it can be quite serious.

This spider will only bite if threatened or cornered and prefers to escape rather than fight back.

The Brazilian banana spider does not have stripes on its legs like the Golden Silk Orb Weaver (Nephilaclavipes). It also tends towards yellow in coloration as opposed to gold. This species’ males are small (less than three inches) while females range from less than three inches up to six inches long including their legs.

What is the largest spider in the world?

The goliath bird eating tarantula is the largest spider in the world ( Theraphosa Blondi). This spider can reach up to one foot in length and uses its huge body and 1 inch-long fangs for eating birds and other unfortunate prey. Although the bite of this spider isn’t dangerous to humans, it can cause nausea and sweating. If it feels threatened, the goliath will have hairs all over its body. This spider emits a creepy hissing sound to warn potential criminals. It can be heard up 15 feet away.

Floridians do not have to be concerned about this giant, South American-native spider.

What is the Smallest Spider in the World

Patu Digua is the smallest spider on the planet, measuring only.37mm in diameter, which is roughly one-fifth of the size of a pin’s head. This spider was first discovered in Rio Digua (Columbia).

What is the largest spider ever recorded?

Guinness World Records claims that the largest known spider was a male goliath-eating spider found in Venezuela in 1965. It measured 11 inches in length and was long enough to cover a dinner plate.


If you’re a Floridian who is thinking about where to live, then it’s important for you to know that there are many different types of spiders. It may be difficult to determine the largest spider in Florida because there are three factors-length of leg span, body weight and size of body–that can all contribute. You should research these six common spiders before making your decision on which one will make you feel at ease. We hope this article has helped! Now go out and explore the world with no fear!
