Banana spiders in Florida, also called golden silk orb-weavers (Trichonephila clavipes), are large, brightly colored spiders known for their golden webs. Despite their intimidating size and appearance, they are not dangerous to humans and rarely bite unless disturbed.
You’re most likely to spot one between July and October, stretched across a trail or patio in a thick, glistening web that looks like something out of a horror movie. But while their size can stop you in your tracks, the truth is: they’re more of a natural pest controller than a pest themselves.
Still, we get it. When a spider the size of your hand shows up by your porch light or builds a web across your garden gate, it’s hard to feel at ease. That’s where knowing the facts, and when to take action, can make all the difference.
We’ve been helping Florida homeowners deal with banana spiders for decades. From identifying their webs to removing nests safely, we provide web removal services that protect your family without disrupting the environment these spiders help balance.
Want to know exactly what you’re dealing with and how to handle it? Below, we’ll walk you through what banana spiders look like, where they live, whether they’re dangerous, and how to keep your outdoor spaces spider-free.
What Is a Banana Spider in Florida?
If you’ve ever stumbled into a shimmering golden web in your backyard or along a Florida trail, there’s a good chance you’ve encountered the banana spider. Scientifically known as Trichonephila clavipes, formerly Nephila clavipes, this arachnid is commonly called the golden silk orb-weaver or, more locally, the giant wood spider. These names reference both its radiant silk and the imposing size of the females.
Female banana spiders are especially hard to miss. With orange-yellow bodies, black-and-gold legs tufted with fuzzy segments, and a leg span that can reach up to 6 or even 7 inches, they’re often mistaken for something far more dangerous. Males, on the other hand, are tiny, usually less than a quarter inch in size, brown, and often overlooked entirely.
Their webs are just as dramatic. Banana spiders spin enormous circular webs, often 3 to 6 feet wide, made from golden silk that shimmers in the sunlight. These webs are strategically built at head-height between trees, across trails, garden spaces, or even porches, right where insects (and unfortunately, people) tend to pass.
How big is a Florida banana spider?
Female banana spiders can reach a leg span of 6–7 inches. While their bodies are only about 1.5 inches long, their long legs create a silhouette that many mistake for a small tarantula.
Where Do Banana Spiders Live in Florida?
Banana spiders thrive in Florida’s hot, humid climate. You’ll find them in wooded parks, suburban neighborhoods, and even tucked into corners of screened patios. Their webs commonly stretch across paths, porches, grill areas, and garden walkways, especially in places like Brevard County, Lakewood Ranch, Sarasota, and other tree-lined communities.
Their favorite locations?
Anywhere open and sunlit with an abundant flying insect population. Trails, the edges of wooded lots, and outdoor play areas are all prime web-building real estate. These spiders tend to construct webs overnight, which means you might walk right into one early in the morning, especially if it’s head-height and nearly invisible in dim light.
Why do banana spiders build webs across trails or doorways?
Banana spiders target areas with high insect traffic, and unfortunately, that often means the same sunny, open walkways and garden paths humans use. It’s not personal; it’s just good hunting.
Though they’re more commonly found outdoors, their presence around homes, especially in fall, can lead to service calls. But unless you're seeing dozens in a small space, a single spider is just nature doing its job.
Are Banana Spiders Dangerous or Aggressive?
Despite their dramatic appearance, banana spiders are not considered dangerous to humans. Their venom is primarily used to immobilize prey like moths and flies and has minimal effect on people. In the rare case of a bite, usually from brushing against a web or startling the spider, most people experience only mild symptoms such as redness, localized pain, or slight swelling, similar to a bee sting.
These spiders are also notably non-aggressive. Even when provoked, banana spiders prefer to retreat rather than defend themselves. There are no recorded fatalities or severe allergic reactions from banana spider bites in Florida, and most encounters end without incident.
Still, caution is wise around young children and small pets. A curious toddler or dog poking around a web may receive a defensive nip, which could lead to mild discomfort or, in rare cases, minor irritation that warrants veterinary attention.
Can a banana spider bite me?
Yes, but only in self-defense. Their bites are uncommon and typically result in minor irritation.
Are banana spiders poisonous to pets?
While banana spider venom is not lethal, very small pets might react more noticeably. Keep an eye on pets that come into contact with webs and consult a vet if any symptoms appear.
Banana Spider Life Cycle And Why You’ll See More in Autumn
The banana spider's life cycle helps explain why their webs seem to appear out of nowhere in late summer and fall. Males become active in midsummer, traveling in search of females. Once they find a suitable mate, males remain near the female’s web for days or even weeks, often competing with other suitors. These battles can be intense, males have been observed losing legs in the process.
After mating, females produce two or more egg sacs, each holding hundreds of eggs. These sacs are typically tucked into corners of the web or hidden nearby, protected within golden silk. When the young spiders hatch, they disperse by "ballooning", floating away on silk threads to establish new territories.
This reproductive surge is why banana spider sightings peak between late July and October. It’s not that they’re suddenly invading, it’s simply mating season, and their webs become larger and more prominent as they reproduce.
While you may see a banana spider holding still in the same place for days, it’s often guarding its egg sacs or waiting to mate, an entirely normal part of its cycle, not a sign of infestation.
As temperatures drop toward the end of fall, the males die off, and females begin to disappear as well, completing the seasonal cycle that resets each summer in Florida’s warm, humid landscape.
When a Friendly Spider Becomes a Frustrating Pest
Banana spiders are passive predators that prefer to be left alone, but that doesn’t make them ideal neighbors, especially when their massive golden webs show up overnight in high-traffic areas.
Webs are often spun at head-height across patios, walkways, or between outdoor structures. For families with children, pets, or frequent guests, these webs can be startling, and make your property feel more wild than welcoming.
Some homeowners also worry about appearances. A spider the size of your palm perched above the porch light doesn’t exactly scream “well-maintained.” While not a sign of infestation, repeated sightings may prompt you to take action.
Will banana spiders keep multiplying if I don’t do anything?
Only if conditions remain ideal. One egg sac can produce hundreds of spiderlings, though few survive. If you don’t want webs recurring in the same spot, proactive removal is key.
Should You Kill Them?
If you’ve discovered a banana spider on your property, the best course of action is relocation.
Banana spiders are beneficial to Florida’s ecosystem. They help control populations of flies, mosquitoes, and moths without posing any threat to people or pets. Killing them removes a natural form of pest control from your yard.
Here’s what you can do instead:
Use a long broom, branch, or pool skimmer to move the spider and web to a more remote corner of your property.
Remove unused webs weekly to discourage rebuilds in unwanted locations.
If you’re working near dense vegetation, wear gloves and long sleeves to avoid surprises.
Avoid pesticide sprays unless absolutely necessary. These chemicals harm helpful species and can disrupt your yard’s ecological balance.
When in doubt, contact Hoffer Pest Solutions for web removal that’s safe for your family and for the spider. Because peace of mind doesn’t have to come at nature’s expense.
Why Spider Sightings Spike in Florida and What You Can Do
As Florida enters the latter half of the year, banana spider sightings surge, and it’s not your imagination. Rising heat, summer rains, and longer days all create perfect conditions for these web-builders to thrive. If your yard provides warmth, moisture, and flying insects, it’s an open invitation.
But that doesn’t mean you’re powerless. With a few preventative steps, you can make your outdoor spaces less appealing to banana spiders without disrupting the local ecosystem.
Here’s what Florida homeowners can do to discourage unwanted webs:
Keep vegetation trimmed around your house to reduce nesting sites and insect activity.
Install motion-sensor lighting to reduce night-time insect swarms, which can attract spiders to porch lights and entryways.
Inspect your yard weekly during peak spider season (July–October), especially after storms or heavy humidity.
Schedule professional web removal if you’re seeing recurring webs or spotting spiders near doors, windows, or children’s play areas.
A little awareness goes a long way toward keeping your property beautiful, and spider-free.

Frequently Asked Questions (FAQ)
Are banana spiders poisonous?
No. While banana spiders do produce venom to subdue their prey, it poses little risk to humans. Their bite, when it happens, is mild and short-lived.
Do banana spiders invade homes?
Rarely. Banana spiders are outdoor dwellers by nature. Unlike recluse or house spiders, they prefer sunlight, trees, and high-traffic insect areas, not dark corners inside your home.
Can they be removed humanely?
Absolutely. Using a long broom or pool skimmer, you can gently relocate their web away from walkways or porches. Professional pest technicians also offer safe web removal if you prefer a hands-off approach.
Do banana spider webs damage trees or shrubs?
Not at all. Their webs may cling to vegetation, but they cause no lasting harm to plants, bark, or branches.
Will I see more banana spiders in future seasons?
Possibly. Warmer winters and wetter summers in Florida create the ideal environment for higher banana spider activity in late summer and fall.
Is it okay to leave banana spider egg sacs near the house?
Yes, but with caution. Each sac may contain hundreds of spiderlings. If you don’t want a seasonal surprise, it’s best to remove the sacs early, especially if they’re near living areas, play spaces, or entryways.
