Whether you’re a curious homeowner or just want to know what might be lurking in your backyard, here’s a ranked list of the ten largest spider species you may encounter in Florida.
Florida is known for sunshine, beaches, and… very big bugs. When it comes to spiders, the Sunshine State has its fair share of large, leggy visitors. Some are harmless giants, while others pack a venomous punch.
1. Golden Silk Orb-Weaver (Banana Spider)
Size: Up to 3 inches (plus leg span)
These long-legged spiders spin massive golden webs in gardens and wooded areas. While intimidating in size, they’re not aggressive toward humans. Their bite is mild and rarely requires treatment.
2. Huntsman Spider
Size: Up to 5 inches leg span
Often mistaken for tarantulas, huntsman spiders are fast, flat, and usually found in garages, sheds, or woodpiles. They’re more likely to run than bite and are actually helpful in reducing pests.
3. Fishing Spider (Dolomedes)
Size: Up to 3 inches
These semi-aquatic spiders are often found near ponds, lakes, and marshes. They can run across water and even dive beneath the surface to catch prey. They look similar to wolf spiders but tend to be larger.
4. Carolina Wolf Spider
Size: Up to 2 inches (body), 4 inches with legs
The largest wolf spider species in North America, the Carolina wolf spider is a ground-dweller that hunts at night. They don’t spin webs and aren’t typically aggressive, though their bite can be painful.
5. Southern House Spider
Size: Up to 2 inches
These spiders are commonly mistaken for brown recluses but are harmless. Males roam indoors in search of mates, which is why they’re often spotted in homes.
6. Spiny Orb-Weaver
Size: 0.5 inch body (but wide appearance)
Known for their crab-like shape and colorful spines, these spiders build small webs in gardens. While not the biggest on the list, their unique look earns them a spot.
7. Trapdoor Spider
Size: Up to 1.5 inches
These secretive spiders stay hidden in burrows with a trapdoor lid. They’re rarely seen but can be large and intimidating when unearthed. Bites are not dangerous but can cause discomfort.
8. Red Widow Spider
Size: 1 to 1.5 inches
Native to Central and South Florida, the red widow is a rare but striking spider with a bright red body. Like its cousin, the black widow, it has neurotoxic venom but rarely comes into contact with people.
9. Black and Yellow Garden Spider (Argiope aurantia)
Size: Up to 1.1 inches (body), legs make them appear much larger
Often found in backyard gardens, these spiders weave large circular webs. They’re non-aggressive and beneficial for insect control.
10. Green Lynx Spider
Size: Up to 1 inch
Bright green and quick-moving, green lynx spiders hunt insects on plants and flowers. They’re rarely seen inside and pose no threat to people.
Are These Spiders Dangerous?
Most of the largest spiders in Florida look intimidating, but pose little to no danger to humans.
Species like the huntsman, wolf spider, and golden silk orb-weaver may bite if provoked, but their venom is mild and symptoms are usually limited to redness, swelling, or minor pain, similar to a bee sting.
The real concern lies with Florida’s venomous spiders, particularly the black widow and red widow. Both have neurotoxic venom, but bites are rare and fatalities are virtually unheard of.
According to the Florida Poison Control Centers, most spider bites reported in the state require minimal treatment, and serious reactions are extremely uncommon. That said, it’s important to treat any bite seriously.
If symptoms like muscle cramps, dizziness, or trouble breathing occur, medical attention should be sought immediately.
And if you’re not sure what kind of spider you’ve seen (or suspect an infestation), professional pest control can help identify and address the issue safely.

When to Call a Professional
Seeing one or two spiders in your home might not be cause for alarm, but if you notice them frequently, it’s time to take a closer look.
