Scorpions in Jacksonville: What You Need to Know
Most Jacksonville residents are surprised to learn that scorpions live in Northeast Florida. We tend to associate scorpions with desert environments — Arizona, New Mexico, West Texas. But Florida is home to three scorpion species, two of which are found regularly in the Jacksonville area. While Florida scorpions aren't as dangerous as their western counterparts, finding one in your home is still alarming and indicates conditions that may attract more.
Scorpion encounters in Jacksonville typically increase during the warmer months (April through October) when these nocturnal arachnids are most active. They're also more commonly reported after heavy rain, which floods their outdoor harborage and drives them to seek drier shelter — often inside your home.
Scorpion Species in Northeast Florida
Florida Bark Scorpion (Centruroides gracilis)
The Florida bark scorpion is the most common species encountered in Jacksonville homes. Adults are 2-4 inches long with dark brown to black bodies and reddish-brown legs. They're called "bark scorpions" because they commonly hide under loose bark on trees, in woodpiles, and under debris. They're excellent climbers and can scale walls, which is how they often end up in attics, on ceilings, and in upper-floor rooms.
Their sting is painful but not medically significant for healthy adults — comparable to a bee sting with localized pain, swelling, and numbness that resolves within a few hours. However, children, elderly individuals, and people with compromised immune systems may experience more severe reactions and should seek medical attention.
Hentz Striped Scorpion (Centruroides hentzi)
The Hentz striped scorpion is smaller (1.5-2.5 inches) and lighter in color — tan to yellowish-brown with darker longitudinal stripes on the back. This species is native to the southeastern United States and is well-adapted to Florida's climate. They're less commonly found indoors than bark scorpions but are present throughout Jacksonville's yards, particularly in areas with sandy soil and ground cover.
Their sting is milder than the bark scorpion's — most people describe it as similar to a mild bee sting with brief, localized pain. They're generally less aggressive and more likely to flee than sting when encountered.
Why Scorpions Enter Jacksonville Homes
Scorpions don't enter your home looking for you — they're seeking three things: moisture, shelter, and prey. Understanding what attracts them helps you prevent future encounters.
Moisture
Scorpions need moisture to survive, and Jacksonville's humid climate generally provides adequate outdoor humidity. However, during dry spells or extreme heat, they seek cooler, moister environments — which often means your home's interior. Bathrooms, laundry rooms, kitchens, and garages are common areas where scorpions are found because of the available moisture.
Shelter from Extremes
During Jacksonville's hottest summer days (when ground temperatures can exceed 140°F in direct sun), scorpions seek shelter in cooler locations. Your home's foundation, walls, and interior provide a temperature-controlled environment that's far more comfortable than the scorching outdoor surfaces. Similarly, heavy rain floods their outdoor hiding spots, driving them to seek dry shelter.
Prey Insects
Scorpions eat insects — crickets, roaches, ants, beetles, and other small arthropods. If your home has an existing pest problem that provides a food source, scorpions are more likely to enter and stay. Reducing your overall pest population through regular pest control also reduces the food supply that attracts scorpions.
How We Eliminate and Prevent Scorpions
Inspection and Identification
We start by identifying the species present, locating entry points, and assessing conditions around your home that attract scorpions. This includes checking exterior walls, foundation gaps, landscaping, mulch beds, woodpiles, and other potential harborage areas. We also inspect the interior — focusing on bathrooms, garages, utility rooms, and areas where scorpions are commonly found.
Exterior Barrier Treatment
Our primary defense against scorpions is a thorough exterior perimeter treatment. We apply long-lasting residual products around the foundation, along entry points, under eaves, around windows and doors, and in landscaping beds adjacent to the structure. This barrier kills scorpions as they attempt to cross from outdoor habitat into your home.
Harborage Reduction
We identify and treat outdoor harborage areas where scorpions hide during the day — under landscape timbers, in rock walls, around woodpiles, and in dense ground cover near the foundation. Treating these areas reduces the local scorpion population and decreases the number attempting to enter your home.
Entry Point Recommendations
We provide specific recommendations for sealing the gaps and cracks that scorpions use to enter your home. Common entry points include gaps under exterior doors, cracks in the foundation, openings around plumbing penetrations, gaps where utilities enter the home, and damaged weatherstripping. Sealing these entry points provides permanent protection that complements our chemical treatments.
Preventing Scorpions Around Your Home
These steps reduce the likelihood of scorpion encounters in your Jacksonville home:
- Seal gaps under all exterior doors with weatherstripping — scorpions can flatten their bodies to fit through surprisingly thin gaps
- Caulk cracks in the foundation and around utility penetrations
- Keep firewood, lumber, and debris piles at least 20 feet from the house
- Trim landscaping and ground cover away from the foundation — maintain a 12-inch clear zone
- Remove rocks, boards, and other ground-level debris from against exterior walls
- Fix moisture issues — repair leaking hose bibs, ensure sprinklers don't spray the foundation, and address drainage problems
- Reduce exterior lighting that attracts insects (scorpion prey) near entry points — or switch to yellow/amber bulbs
- Shake out shoes, gloves, and clothing that's been stored in garages or outdoors before wearing
