The most familiar types of house spiders in Florida include southern house spiders, common house spiders, cellar spiders, brown widows, and jumping spiders. Some build webs in quiet corners, while others actively hunt insects along walls and windows.
South Florida homeowners may encounter these spiders in garages, bathrooms, lanais, and outdoor storage areas. Knowing how each one behaves, where it hides, and whether it bites can help you identify potential concerns and prevent spiders from settling around your home.
Key Takeaways
- Five spider groups commonly turn up around Florida homes. Southern house spiders, common house spiders, cellar spiders, and brown widows use webs to catch prey, while jumping spiders actively hunt insects.
- Most household spiders rarely bite people. Brown widows deserve extra caution because their venom can cause painful symptoms that sometimes require medical attention.
- Recurring spider activity can point to available insect prey. Clearing clutter, reducing excess moisture, sealing entry points, and controlling household insects help make your home less attractive to spiders.
5 Common Types of House Spiders in Florida
Not all house spiders in Florida behave the same way. Some stay in one spot for weeks, while others wander through rooms or across outdoor surfaces searching for food. Recognizing their hunting habits and hiding places can help you narrow down which spider you’re seeing.
| Spider Type | Typical Behavior | Common Hiding Places | Bite Risk |
| Southern house spider | Waits near crevice webs; males wander | Shutters, eaves, wall cracks | Low |
| Common house spider | Traps insects in tangled webs | Windows, garages, sheds | Low |
| Cellar spider | Hangs in loose webs and vibrates when disturbed | Bathrooms, ceilings, utility rooms | Low |
| Brown widow | Waits in irregular webs | Patio furniture, outdoor equipment | Greater concern |
| Jumping spider | Stalks and jumps onto insects | Windowsills, screens, sunny walls | Low |
Southern House Spiders
Southern house spiders often settle into cracks around building exteriors. Females have dark, stocky bodies and spend most of their time near their webs, while males have slimmer bodies and roam in search of mates.
These spiders build woolly-looking webs that extend outward from narrow openings. When an insect touches the silk, the female detects the movement from her hiding place.
Check behind shutters, under eaves, and around siding gaps. Wandering males sometimes enter homes and get mistaken for brown recluse spiders because of their similar appearance. Southern house spiders can bite when trapped or handled, but bites are uncommon and generally not medically significant.
Common House Spiders
Those messy cobwebs collecting dust near a garage window may belong to common house spiders. They have rounded abdomens with brown, gray, or tan markings and tend to remain close to their webs.
Instead of chasing insects, these spiders wait for small flies, moths, and other prey to become tangled in their silk. They often choose ceiling corners, storage sheds, window frames, and sheltered garage spaces.
Old webs can remain after a spider moves elsewhere, so cobwebs alone don’t confirm an active population. Common house spiders rarely bite people, and their bites are generally not a medical concern.
Cellar Spiders
Cellar spiders are recognizable by their small bodies and extremely long, thin legs. You’ll often find them hanging upside down in loose webs near ceilings, plumbing, or utility equipment.
When disturbed, some cellar spiders shake rapidly in their webs. This movement can make it harder for predators to target them.
They feed on small insects and sometimes other spiders, which helps explain why they remain in quiet corners where prey occasionally passes. Bathrooms, laundry rooms, and garages are familiar hiding places. Cellar spiders rarely bite humans, and the popular claim that they’re exceptionally dangerous isn’t supported by evidence.
Brown Widow Spiders
Brown widows deserve more caution than most common house spiders in Florida. Females are typically tan or brown with darker markings and build irregular webs in protected spaces.
One of their most recognizable features is the egg sac, which has pointed projections that give it a spiky appearance.
Brown widows often hide beneath patio furniture, inside outdoor storage areas, and around sheltered equipment. Because they tend to stay near their webs, accidental contact can happen when you move objects without checking underneath.
Their bites can cause pain and other symptoms that sometimes require medical care. The University of Florida provides identification information to help distinguish this species from other spiders.
Jumping Spiders
A small spider that pauses, turns toward you, and suddenly leaps across a windowsill may be a jumping spider. These compact spiders have prominent forward-facing eyes and rely heavily on vision when hunting.
Unlike web-building spiders, jumping spiders stalk insects before making short, controlled jumps to catch them. They produce silk for safety lines and shelter rather than building large prey-catching webs.
You’ll often see them on window screens, sunny exterior walls, patio railings, and plants near the house. Jumping spiders may bite if squeezed or handled, but bites are uncommon and usually cause minor local symptoms.
What House Spiders Can Tell You About Other Pests
Finding an occasional spider indoors doesn’t automatically mean you have an infestation. However, seeing spiders repeatedly in the same places may indicate that insects are available for them to eat.
Spiders feed on flies, mosquitoes, moths, and other small arthropods. A web near a garage window may be positioned to catch flying insects, while a jumping spider on a patio screen could be hunting smaller pests nearby.
What Spider Activity Around Your Home May Mean
| What You Notice | What to Check |
| Fresh webs around garage windows | Flying insects and damaged screens |
| Spiders near porch lights | Insects gathering around outdoor lighting |
| Cellar spiders in utility rooms | Undisturbed corners and nearby insect activity |
| Jumping spiders on patio screens | Small insects resting on screens |
| Recurring webs in storage spaces | Clutter and sheltered hiding places |
These observations offer clues, but they don’t prove that your home has a serious pest problem. A spider can survive on occasional prey, and some enter houses accidentally. The University of Minnesota Extension covers household spider behavior and management.
If you also notice frequent flies, cockroaches, or ants, investigate those insects rather than focusing only on the spiders. Reducing available prey can help discourage spiders from remaining indoors.
How to Keep House Spiders Out of Your Florida Home
Removing visible spiders and webs can help immediately, but lasting spider prevention requires making your home less appealing to them. Focus on the places where you’ve noticed activity instead of treating every room the same way.
Remove Clutter and Old Webs
Spiders often settle in spaces that rarely get disturbed. Stacked cardboard boxes, crowded garage shelves, and unused patio furniture can provide protected hiding places.
Move stored belongings into closed plastic containers and keep enough space around shelves to clean behind them. Vacuum accessible webs and egg sacs from ceiling corners, window frames, and garage openings. Checking these areas regularly makes fresh spider activity easier to spot.
Fix Moisture Problems
Florida’s humid conditions support many insects that thrive around moisture. Although not every spider prefers damp areas, controlling moisture can help reduce certain insects they feed on.
Inspect leaking pipes, condensation around air conditioning equipment, and damp spaces beneath sinks. Improve bathroom ventilation and fix drainage problems that leave water collecting near the house.
Seal Entry Points
Small gaps around windows, doors, and exterior walls can let spiders and insects inside. Damaged screens and worn weatherstripping are especially worth checking.
Inspect sliding patio doors, garage door seals, window frames, and openings around utility lines. Repair torn screens and close gaps with appropriate sealing materials.
Reduce Household Insects
Removing webs won’t address the insects that may be attracting spiders. Keep food stored properly, clean up crumbs, empty trash regularly, and address recurring insect activity.
Outdoor lighting can also influence where insects gather. Adjusting unnecessary nighttime lights or using fixtures that attract fewer insects may reduce activity near entrances. When insects continue appearing indoors, general pest control can help address the underlying problem.
Which House Spider Bites Should You Worry About?
Most Florida house spiders prefer to avoid people. Bites generally occur when a spider becomes trapped against the skin, such as when someone reaches into a storage box or puts on clothing where a spider is hiding.
Southern house spiders, common house spiders, cellar spiders, and jumping spiders rarely cause medically significant bites. Brown widows require greater caution because their venom can cause pain, muscle cramping, and other symptoms.
What to Do After a Suspected Spider Bite
Wash the affected area with soap and water and apply a cool compress. Avoid squeezing the bite or attempting to remove venom.
Seek prompt medical attention if you develop severe pain, muscle cramps, breathing difficulties, or other significant symptoms. The Centers for Disease Control and Prevention (CDC) explains symptoms and precautions associated with concerning bites.
If you can safely photograph the spider without touching it, the image may help with identification. A skin reaction alone usually isn’t enough to determine what caused a suspected bite.

Florida House Spiders: FAQs
What is the most common house spider in Florida?
Several spider groups regularly appear around Florida homes, including common house spiders, southern house spiders, and cellar spiders. There isn’t one confirmed species that dominates every property. The spiders you encounter depend on nearby vegetation, available shelter, and the insects around your home.
Are house spiders in Florida dangerous?
Most familiar house spiders rarely bite and aren’t considered a serious medical threat. Brown widow spiders deserve greater caution because their bites can produce painful symptoms. Avoid handling spiders you can’t identify, especially those hiding beneath outdoor furniture or inside storage containers.
Why do I keep finding spiders in my house?
Repeated spider sightings may indicate available insect prey, sheltered hiding places, or gaps that allow them indoors. Check window screens, garage seals, storage areas, and locations where other insects gather. Addressing these conditions can help reduce how often spiders appear.
What attracts spiders to a clean house?
Even clean homes can attract spiders if insects are present or entry points remain open. Outdoor lighting may draw flying insects toward windows, while quiet storage spaces provide hiding places. Regular cleaning helps, but managing insects and sealing openings are equally useful.
How do I get rid of house spiders without them coming back?
Start by vacuuming webs, removing clutter, repairing screens, and sealing gaps around doors and windows. Fix moisture problems and reduce household insects that provide food for spiders. These steps won’t prevent every spider from entering, but they can make recurring activity less likely.
