Huntsman spiders in Florida can look alarming because of their size, speed, and long legs. The species most often discussed in Florida is the pantropical huntsman spider, also called the giant crab spider. It is a large, flattened brown spider that may show up in garages, sheds, closets, under furniture, or around sheltered outdoor areas.
The main thing to know is that huntsman spiders are not considered dangerous. They can bite if trapped or handled, but they are mostly nuisance spiders that hunt insects instead of building webs to catch prey.
Key Takeaways
- Huntsman spiders are large, fast, flattened spiders found in parts of Florida.
- They do not use webs to trap prey.
- They may hide in cracks, closets, garages, sheds, and under furniture.
- They are sometimes mistaken for brown recluse spiders.
- Frequent sightings may point to insect activity or easy entry points.
What Do Huntsman Spiders Look Like?
Huntsman spiders have a wide, flattened body and long legs that spread outward in a crab-like position. That shape is one reason they are sometimes called giant crab spiders.
The University of Florida’s profile of the pantropical huntsman spider describes it as a large brown spider with a body length of about one inch and a leg span of roughly three to five inches. Its flattened body helps it fit into narrow cracks and tight hiding spots.
Common identification clues include:
- Brown or tan coloring
- Long legs that angle outward
- A broad, flat body shape
- Fast movement across walls, floors, or furniture
- Little web activity compared with other spiders
- Black spots on the legs in some specimens
Because they are large and quick, they are easy to notice when they appear indoors.
Where Huntsman Spiders Live In Florida
Huntsman spiders are more likely to be found in warm, sheltered areas. In Florida, they may live outdoors in protected spaces or move into buildings where they can find insects, cracks, and cover.
Around homes, they may hide in:
- Garages
- Sheds
- Closets
- Attics
- Cabinets
- Behind wall hangings
- Under furniture
- Under boards or stored materials
- Cracks and crevices near entry points
In South Florida, where frost is rare, huntsman spiders can also survive outdoors in some areas. Their flat body makes it easier for them to slip into tight places that homeowners may not inspect often.
How Huntsman Spiders Behave
Huntsman spiders are active hunters. They do not build sticky capture webs like orb weavers or cellar spiders. Instead, they use speed, strong jaws, and venom to catch insects.
That behavior explains why homeowners often see them moving suddenly across a wall, floor, garage, or patio instead of sitting in a web. They may hunt roaches and other household insects, which can make them beneficial outdoors or in non-living spaces. Inside a home, though, most people would rather not share rooms with a large spider.
Females carry a flattened, disc-like egg sac under the body. UF/IFAS notes that those egg sacs can contain more than 200 eggs, which is one reason sightings should be checked if you notice egg sacs or repeated spider activity.
Are Huntsman Spiders Dangerous?
Huntsman spiders are not considered dangerous to people. They are sometimes mistaken for brown recluse spiders, but UF/IFAS notes that the pantropical huntsman spider is not related to the brown recluse and is not dangerous.
A bite can still happen if the spider is grabbed, pressed against skin, or trapped in clothing or shoes. A huntsman bite may cause local pain and swelling, but serious reactions are not typical.
For bite questions, the Florida Poison Information Center Network recommends calling poison control for immediate guidance after a bite or sting, especially if there is an allergic reaction or concern about a venomous species.
Why Huntsman Spiders Come Inside
Huntsman spiders usually enter homes while looking for prey or shelter. They may also come in through small openings because their flattened bodies let them squeeze into tight gaps.
Common reasons they may show up indoors include:
- Roaches, flies, or other insects inside the home
- Gaps around doors, windows, or utility lines
- Open garage doors
- Cluttered storage areas
- Outdoor items brought inside
- Cracks near baseboards or cabinets
- Warm, sheltered spaces during cooler weather
If you see one huntsman spider, it may have wandered in. If you keep seeing them, the issue may be tied to insect activity, open access points, or hidden harborage areas.
Huntsman Spiders Vs. Other Florida Spiders
Florida has many large or brown spiders, so misidentification is common. These comparisons can help narrow things down.
Huntsman Spiders Vs. Wolf Spiders
Wolf spiders are usually ground hunters with a sturdier, hairier look. Huntsman spiders tend to look flatter and wider, with legs that extend outward to the sides.
Wolf spiders are often seen running across floors, patios, or grass. Huntsman spiders may be seen on walls, behind objects, or squeezing into tight spaces.
Huntsman Spiders Vs. Brown Recluse Spiders
Huntsman spiders may be mistaken for brown recluse spiders because both can be brown, but they are different. Huntsman spiders are larger, flatter, and have long legs that spread outward.
Brown recluse spiders are not identified by color alone. If you see a brown spider and are unsure what it is, avoid handling it directly and take a clear photo if possible.
Huntsman Spiders Vs. Cellar Spiders
Cellar spiders have very long, thin legs and usually sit in loose, messy webs in corners. Huntsman spiders are more robust, flatter, and more likely to be seen moving without a web.
Huntsman Spiders Vs. Orb Weavers
Orb weavers build circular webs outdoors. Huntsman spiders do not build those wheel-shaped webs and are usually found hiding, running, or hunting insects.
Signs Huntsman Spiders May Be A Problem
A single huntsman spider sighting does not always mean you have an infestation. Still, repeated sightings around the same rooms or entry points deserve attention.
Watch for:
- Large spiders appearing more than once indoors
- Sightings in closets, garages, attics, or sheds
- Spiders hiding behind wall decor or furniture
- Egg sacs or multiple young spiders
- Roach or insect activity in the same areas
- Gaps around doors, windows, cabinets, or utility lines
- Spiders returning after cleaning or removal
Because huntsman spiders feed on insects, repeated sightings may be a sign that other pests are active nearby.
How To Keep Huntsman Spiders Out
Prevention works best when you focus on access, clutter, and insect activity.
Start with entry points. Replace worn door sweeps, repair torn screens, seal gaps around utility lines, and check spaces around garage doors. Inspect weatherstripping around exterior doors, especially if you see spiders near thresholds.
Then reduce hiding spots:
- Keep garages and sheds organized.
- Move storage boxes off the floor when possible.
- Shake out shoes, gloves, and outdoor gear before use.
- Remove unused cardboard and clutter.
- Vacuum corners, baseboards, and behind furniture.
- Keep outdoor debris away from the foundation.
Finally, address insects. If roaches, flies, or other pests are active, huntsman spiders may follow the food source. Reducing prey can make the home less attractive to spiders.
When To Call For Spider Control
Professional spider control makes sense when huntsman spiders keep appearing indoors, when you are finding egg sacs, or when you cannot tell which spider you are seeing. It is also helpful when spiders are appearing in bedrooms, closets, bathrooms, or other high-contact areas.
