Spiders in Florida: Common Species, Which Are Dangerous, and How to Keep Them Out

Florida’s warm, humid climate is paradise for spiders, and homeowners across the state share their yards and occasionally their homes with dozens of species. The good news is that the overwhelming majority are harmless — even helpful — and only two are worth real caution. Knowing how to tell them apart takes the fear out of the next eight-legged encounter. Here’s a guide to the spiders you’ll actually see in Florida, which ones matter, and how to keep them out of your living space.

Common Spiders You’ll See in Florida

Here are the species Florida homeowners encounter most, and what to know about each:

Spider	How to Recognize It	Danger?
Common house spider	Small, brown/tan, builds tangled webs in corners and undisturbed indoor spots.	Harmless
Golden silk orb-weaver (banana spider)	Large, colorful, spins big golden webs outdoors between trees and eaves.	Harmless
Wolf spider	Large, hairy, fast ground hunter that builds no web; often mistaken for a recluse.	Harmless
Huntsman spider	Very large, flat, fast; favors garages and walls. Alarming but not dangerous.	Harmless
Black widow	Shiny black with a red hourglass underneath; hides in sheds, woodpiles, garages.	Venomous
Brown widow	Tan/brown with an orange hourglass; spiky egg sacs; common around homes.	Venomous

The Two Spiders Worth Watching For

Black Widow

The southern black widow is Florida’s most notable venomous spider. Females are shiny black with the classic red hourglass marking on the underside of the abdomen. They’re reclusive, preferring dark, undisturbed spots like sheds, garages, woodpiles, and outdoor furniture, and they bite only when accidentally pressed against skin. A black widow bite can cause muscle pain, cramping, and other symptoms and warrants medical attention, though serious outcomes are rare with prompt care.

Brown Widow

The brown widow is an increasingly common relative of the black widow, tan to brown with an orange hourglass and distinctive spiky egg sacs. Its venom is similar to the black widow’s, but it tends to deliver less of it, so bites are usually less severe. Brown widows love the nooks of homes — under railings, patio furniture, and grills — so they’re worth knowing.

We cover that mix-up in detail in our guide to the brown recluse spider in Florida, and the most commonly misidentified culprit in our guide to wolf spiders.

Are Spiders Actually Good to Have Around?

Ecologically, yes. Spiders are natural pest controllers, eating mosquitoes, flies, roaches, and other nuisance insects. A few harmless spiders outdoors are a sign of a healthy yard, and they keep other pest populations in check. The goal of spider control usually isn’t to wipe them out entirely — it’s to keep them out of your living spaces and to eliminate the genuinely venomous species from areas where people and pets spend time.

Why Spiders Come Indoors

• Prey. They follow their food — if your home has insects, spiders come to hunt them.
• Entry points. Gaps under doors, cracks, torn screens, and openings around pipes let them slip inside.
• Shelter. Boxes, clutter, and undisturbed corners give them places to hide and build webs.
• Lighting. Outdoor lights attract insects, which draws the spiders that eat them right to your doorways.

How to Keep Spiders Out of Your Home

• Seal entry points. Inspect and seal gaps around doors, windows, the foundation, and utility lines; add door sweeps and repair screens.
• Declutter. Reduce clutter in garages, closets, attics, and basements, and store items in sealed bins.
• Remove webs. Regularly sweep away webs and egg sacs from corners, eaves, and ceilings.
• Manage lighting. Switch outdoor lighting to yellow “bug” bulbs or sodium-vapor lights, or move lights away from doors.
• Maintain landscaping. Trim shrubs and vegetation back from the house and keep firewood away from exterior walls.
• Cut off their food. Control the insects spiders feed on — fewer bugs means fewer spiders.

When to Call a Professional

Call a pro if you’re finding venomous widow spiders around your home, seeing spiders repeatedly, or discovering egg sacs that signal a growing population. A professional identifies the species, safely removes dangerous spiders, treats the insects that attract them, and sets up a barrier to keep them out.

Frequently Asked Questions

Question	Answer
What is the most dangerous spider in Florida?	The black widow is Florida’s most medically significant spider, identifiable by its shiny black body and red hourglass. The brown widow is also venomous but usually milder. The brown recluse is not established in Florida.
Are there brown recluse spiders in Florida?	No — the brown recluse is not established in Florida. Most spiders mistaken for recluses here are harmless wolf or huntsman spiders. See our dedicated brown recluse guide for details.
What is the big spider I see in my Florida yard?	It’s usually a golden silk orb-weaver (banana spider) if it’s in a large web outdoors, or a wolf or huntsman spider if it’s a fast ground-runner. All three are large but harmless.
How do I keep spiders out of my house?	Seal entry points, declutter, remove webs, switch to yellow outdoor lighting, trim vegetation away from the house, and control the insects spiders feed on. Reducing their food and access is the most effective approach.
Do Florida spiders bite?	Most won’t, and the harmless species rarely bite even when handled. Black and brown widows can bite if pressed against skin and warrant medical attention. Otherwise, Florida’s common spiders pose little risk.
Should I be worried about spiders in my home?	Usually not. The vast majority are harmless and beneficial. The exception is finding venomous widow spiders in areas you use — those are worth removing professionally for safety.
