Tan to dark brown with an orange or yellow hourglass marking on the underside of the abdomen (not red like the black widow). The egg sac is the clearest ID clue — it has distinctive spiky projections, like a sputnik satellite.
Underside of outdoor furniture, inside PVC piping, mailboxes, playground equipment, behind shutters, meter boxes and low shrubs. Extremely common across Florida's coast.
- Spiky, sputnik-shaped egg sacs in low corners and under outdoor furniture
- Webs in chairs, under patio tables, eaves and meter boxes
- Tan-brown spider with orange hourglass hiding in any undisturbed outdoor void
Brown widow venom is more potent than black widow venom per volume, but the spider injects less and is less aggressive. Bites are painful and can cause local swelling, nausea and cramping. Seek medical care if symptoms spread.
Should I call today?
Yes, get it looked at promptly. Brown Widow Spider causes damage or health problems that compound while you wait, and the cost of that damage is the part that actually gets expensive — not the treatment. An inspection is free, so there's no reason to guess.
Rhino de-webs, removes egg sacs and treats the harborage directly, then maintains an exterior barrier program to prevent re-establishment.
