You found a widow spider in your Plantation garage — but which one? In South Florida, that web is far more likely to belong to a brown widow than the famous black widow, and the difference matters for how worried you should be. Here’s how to tell them apart at a glance.
Brown Widow vs. Black Widow at a Glance
- Color: Brown widow = tan/mottled brown; black widow = glossy jet black
- Hourglass: Brown widow = orange-to-yellow; black widow = bright red
- Egg sac: Brown widow = spiky, tufted ball; black widow = smooth, round, teardrop
- Behavior: Brown widow is shy and flees; black widow is more defensive
- In Broward: Brown widows are now far more common around homes than black widows
Why This Matters in South Florida
Both spiders are widows, both are venomous, and both turn up around Broward County homes. But over the past couple of decades the brown widow has spread aggressively across South Florida and, in most urban and suburban neighborhoods, now outnumbers the native black widow. So when a Plantation homeowner finds a widow under the patio table, odds are it’s a brown widow. Knowing which one you’re looking at tells you how cautious to be — and the good news is that the more common species is also the less dangerous of the two.
How to Tell Them Apart
Body color
This is the easiest tell. The black widow (southern black widow, the common Florida species) has a glossy, almost shiny jet-black body. The brown widow is tan to brown with a mottled, patchy pattern — often described as looking “dusty” or marbled, sometimes with faint banding on the legs. If it’s solid shiny black, it’s a black widow; if it’s patterned brown and tan, it’s a brown widow.
The hourglass
Both have the signature hourglass marking on the underside of the abdomen, but the color differs. The black widow’s hourglass is a vivid, unmistakable red. The brown widow’s is more muted — typically orange to yellowish. The shape is similar, but the bold red versus soft orange is a reliable confirmation.
The egg sac — the dead giveaway
If you spot the egg sac, you don’t even need to see the spider. A brown widow’s egg sac is covered in spiky, pointed tufts — it looks like a tiny spherical sea mine or a pollen burr. A black widow’s egg sac is smooth, round to teardrop-shaped, with a papery surface. The spiky sac is one of the most dependable ways to confirm a brown widow infestation in a Broward garage or under the eaves.
Where you find them
Brown widows love the structured nooks of human spaces — under patio furniture, inside mailboxes and meter boxes, in the folds of grill covers, behind shutters, under the lip of plastic chairs and planters. Black widows tend toward darker, more secluded spots — woodpiles, garage corners, sheds, and undisturbed clutter. There’s plenty of overlap, but brown widows are the ones you’ll typically find right out in your everyday outdoor living areas.
The venom paradox: Here’s the surprising part — drop for drop, brown widow venom is roughly as potent as black widow venom. But brown widows inject far less of it and are far more timid, so their bites are usually much milder, often just localized pain and redness. The black widow, though less common, delivers the more serious bite. More common does not mean more dangerous in this case.
Which One Should You Worry About More?
The black widow is the bigger medical concern. A black widow bite can cause significant pain, muscle cramping, sweating, and nausea, occasionally requiring medical treatment — though serious outcomes are rare with prompt care. Brown widow bites tend to stay localized and mild. That said, neither belongs around your kids’ play area, your patio cushions, or the spaces you reach into daily. Both warrant removal, especially in homes with children or pets, because the risk of an accidental bite is highest exactly where these spiders like to hide.
How to Keep Both Widows Out
- Declutter garages, sheds, and the foundation perimeter to remove hiding spots
- Inspect and remove egg sacs — destroying the spiky brown-widow sacs prevents the next generation
- Check before you grab — wear gloves reaching under furniture, into mailboxes, or into stored boxes
- Sweep webs from patio furniture, soffits, and behind shutters regularly
- Seal entry points around doors, windows, and utility lines
- Control other insects — widows go where the prey is, so reducing flies, roaches, and other bugs reduces spiders

If you find a glossy black spider with a bright red hourglass and a smooth egg sac, you’ve got a black widow — the more dangerous of the two. If it’s mottled brown with an orange hourglass and a spiky egg sac, it’s a brown widow — far more common in South Florida but generally milder. Either way, both are unwelcome in the places your family uses every day. Professional spider removal takes the guesswork and the risk out of dealing with them, clearing the spiders and their egg sacs and keeping your patio, garage, and yard widow-free.
Frequently Asked Questions
How can I quickly tell a brown widow from a black widow?
Look at color and the egg sac. A black widow is glossy jet black with a bright red hourglass and a smooth, round egg sac. A brown widow is mottled tan-brown with an orange-to-yellow hourglass and a distinctive spiky, tufted egg sac. The spiky sac is the surest sign of a brown widow.
Is a brown widow as dangerous as a black widow?
Their venom is similarly potent drop for drop, but brown widows inject far less and are more timid, so their bites are usually much milder — often just localized pain and redness. The black widow delivers the more serious bite, though severe outcomes are rare with prompt medical care.
Which widow is more common in Plantation, FL?
The brown widow. Over recent decades it has spread aggressively across South Florida and now typically outnumbers the native black widow around homes. If you find a widow under your patio furniture or in a mailbox in Broward County, it’s most likely a brown widow.
Should I remove a widow egg sac myself?
You can carefully remove and destroy egg sacs if you can do so safely with gloves and a tool, since each sac can hatch many spiderlings. But if you’re finding multiple sacs or live widows repeatedly, the population is established and professional treatment is the more reliable way to clear them and prevent return.
