Where do brown/black widow spiders hide around in florida homes?
Florida’s warm, humid climate creates ideal conditions for many spider species — including widow spiders. In Florida, homeowners most commonly encounter the Southern black widow and the Brown widow spider. Both belong to the widow spider group and are venomous, though their behavior and risk levels differ slightly.
If you’re wondering where they hide — and how concerned you should be — here’s the full breakdown.
Where Widow Spiders Hide in Florida Homes
Widow spiders prefer dark, quiet, undisturbed areas. They are not aggressive hunters and build irregular, tangled webs near the ground.
Common Outdoor Hiding Spots
Under patio furniture
Inside grill covers
In potted plants
Beneath window sills
Around outdoor light fixtures
Inside mailboxes
In garages and sheds
Under decks and staircases
Brown widows in particular are well adapted to suburban environments and are frequently found around man-made structures.
Common Indoor Hiding Spots
While less common indoors than outdoors, they may hide:
In cluttered garages
Inside storage boxes
Under shelves
In rarely used closets
Around water heater closets
Inside shoes left in garages
Widows tend to stay low to the ground and avoid high-traffic living areas.
How to Identify Them
Southern Black Widow
Glossy black body
Distinct red hourglass marking on underside of abdomen
Females are about 1.5 inches across including legs
Brown Widow
Light to dark brown body
Orange or yellowish hourglass marking
Legs often banded
Egg sacs are spiky or tufted (a key identifier)
The brown widow has become increasingly common in Florida over the past few decades and is now widespread throughout the state.
How Dangerous Are They?
Both species are venomous, but serious complications are uncommon.
Widow venom contains a neurotoxin that affects the nervous system. A bite may cause a condition called latrodectism.
Typical Symptoms
Sharp pain at bite site (sometimes delayed)
Muscle cramping or spasms
Abdominal pain
Sweating
Nausea
Pain can be significant but is rarely life-threatening in healthy adults.
Severity Differences
Southern black widow bites tend to cause more pronounced symptoms.
Brown widow bites are generally considered milder on average, though medically significant reactions can still occur.
Deaths from widow spider bites in the United States are extremely rare, especially with modern medical care.
Higher-risk groups include:
Young children
Elderly individuals
People with underlying health conditions
What To Do If You Encounter One
If you see a widow spider:
Do not handle it.
Avoid disturbing its web.
Wear gloves when cleaning garages or moving stored items.
Shake out shoes and gardening gloves stored outdoors.
If removal is needed, professional pest control is recommended rather than attempting direct contact.
What To Do If Bitten
If you suspect a widow spider bite:
Wash the area with soap and water.
Apply a cold pack to reduce pain and swelling.
Elevate the affected area if possible.
Seek medical advice, especially if symptoms worsen.
Go to urgent care or the emergency room if you experience:
Severe muscle pain or cramping
Difficulty breathing
Chest pain
Worsening systemic symptoms
Doctors may provide pain control, muscle relaxants, or supportive care. Antivenom exists but is typically reserved for severe cases.
If possible and safe, a photo of the spider can help with identification — but never risk another bite trying to capture it.
How Common Are Widow Spiders in Florida?
Florida’s climate allows widow spiders to remain active most of the year. They are common statewide, particularly in suburban and coastal areas. However, bites are relatively uncommon because:
They are not aggressive.
They bite mainly when pressed against skin (for example, inside a glove or shoe).
They prefer retreat over confrontation.
Most encounters happen accidentally while moving stored items or working outdoors.
Brown and black widow spiders do live around Florida homes, especially in garages, sheds, and outdoor furniture. While they are venomous and capable of delivering painful bites, they are not aggressive and serious outcomes are rare with prompt medical care.
