Florida is home to three scorpion species that regularly turn up inside houses, and while a sting is painful, none of them carry venom dangerous enough to cause serious harm in healthy adults. Understanding which species you’re dealing with, how they get inside, and what draws them in will help you keep them out for good.
Scorpion Species Found in Florida Homes
The three species most commonly spotted across the state are the Hentz striped scorpion, the slender brown scorpion, and the Keys bark scorpion. Of these, the Hentz striped scorpion is the most widespread, found in every region of Florida. It’s small, typically tan or yellowish-brown with darker stripes running lengthwise down its back, and rarely exceeds two to three inches.
The slender brown scorpion is larger and darker, usually a solid reddish-brown to black. It’s more common in South Florida and urban areas, often hiding under bark, debris, or the loose edges of stucco walls. The Keys bark scorpion is mostly restricted to the Florida Keys and Monroe County, so if you’re in central or northern Florida, you’re almost certainly encountering one of the first two.
None of these species produce venom strong enough to cause life-threatening symptoms. The only scorpion in the United States with medically significant venom is the Arizona bark scorpion, which does not live in Florida. Of the more than 2,000 scorpion species worldwide, only about 100 produce venom that could be fatal, and none of them are native to the state.
How Scorpions Get Inside
Scorpions don’t invade homes in large colonies the way ants or termites do. They wander in individually, usually driven by drought, heavy rain, or a search for prey insects. What makes them so effective at getting indoors is their body shape. A scorpion can squeeze through any gap as narrow as 1/8 of an inch, which means most Florida homes have dozens of potential entry points.
The most common routes include gaps beneath exterior doors, unsealed spaces around windows, and openings where plumbing pipes pass through walls. Kitchen and bathroom cabinets are frequent entry zones because pipes run directly through the wall behind them. Scorpions also enter through weep holes in brick or block construction, around air conditioning line sets, and through gaps in attic or foundation vents. Once inside, they seek dark, damp hiding spots: inside shoes, under damp dish towels left on counters, in closets, or occasionally in bedding.
What Draws Them to Your Home
Moisture is the single biggest attractant. If you find a scorpion indoors, there’s likely a water source nearby, whether that’s a leaky pipe, a condensation-prone air conditioning unit, or a dripping hose bib on the exterior wall. Scorpions are predators that feed on insects, spiders, and other small arthropods, so a home with a bug problem is also a home that looks appealing to scorpions. Outdoor lighting that attracts flying insects near doorways and windows effectively sets a dinner table right at your entry points.
Landscaping plays a role too. Rock beds, wood piles, leaf litter, and dense ground cover against the foundation create perfect daytime hiding spots. Scorpions are nocturnal, so they shelter in these areas during the day and explore outward at night, often right into your house if a gap is available.
What a Sting Feels Like
A Florida scorpion sting is comparable to a wasp sting: sharp, immediate pain at the site followed by localized numbness, tingling, slight swelling, and warmth. Symptoms typically stay confined to the area around the sting and resolve within a few hours to a day. Most healthy adults don’t need any medical treatment beyond basic first aid.
To treat a sting at home, wash the area with mild soap and water, apply a cool compress, and take an over-the-counter pain reliever like ibuprofen if needed. Don’t try to suck out venom or cut the skin around the sting. Check that your tetanus vaccination is current.
Young children and older adults face a higher risk of more serious reactions. In rare cases, venom that affects the nervous system can cause muscle twitching, difficulty breathing, drooling, sweating, nausea, or rapid heart rate. If a scorpion stings a child, contact Poison Help at 800-222-1222. Anyone who has had even a mild allergic reaction to a previous sting should be aware that future stings can trigger anaphylaxis, a severe whole-body allergic reaction that requires emergency care.
Sealing Your Home Against Entry
Prevention starts with eliminating the gaps scorpions use to get inside. Fit tight-fitting door sweeps on every exterior door and check them each season, since Florida’s sun degrades rubber and bristle strips quickly. Apply weather stripping around windows and doors where daylight or air is visible. Caulk around all utility penetrations: pipes, electrical conduit, hose bibs, and air conditioning line sets. Screen weep holes and attic or foundation vents with fine mesh.
Indoors, fix any moisture problems. Repair leaky pipes under sinks, address condensation from air conditioning units, and wipe down kitchen surfaces to remove food residue that attracts the insects scorpions hunt. During peak season (late spring through fall in most of Florida), shake out shoes, towels, and bedding before use, and keep beds pulled a few inches away from walls.
Yard and Landscape Changes
Pull rock beds, pavers, and woodpiles at least a couple of feet back from your foundation. Store firewood off the ground on a raised rack. Trim shrubs and tree limbs so nothing touches your roof or exterior walls, since scorpions are good climbers and will use branches as a bridge onto the structure. Repair irrigation leaks and eliminate any sources of standing water in the yard.
Switching exterior lights near doorways to yellow or amber “bug light” bulbs, or moving lights away from the house entirely, reduces the number of flying insects congregating at entry points. Fewer prey insects near the house means less reason for scorpions to approach.
Treating an Active Problem
If you’re finding scorpions inside regularly, one-time treatment rarely solves the problem. Ongoing perimeter treatment around the exterior foundation is the most effective chemical approach. Bifenthrin-based liquid insecticides applied as a barrier around the base of the home and on surrounding landscaping create a contact-kill zone that intercepts scorpions before they reach entry points. For cracks, crevices, and tight entryways that can’t be sealed permanently, an insecticidal dust applied into the gap provides longer-lasting residual protection in sheltered spaces where liquid spray breaks down quickly.
A professional pest control service can assess your specific entry points and moisture issues, but many homeowners manage the problem themselves with a combination of sealing, moisture control, and perimeter spraying. The key is consistency. Reapply perimeter treatments on the schedule recommended by the product label, and reinspect seals and sweeps seasonally. Scorpions are solitary and slow to reproduce, so a sealed, dry, well-maintained home becomes unappealing quickly once their access routes are cut off.
