Common Types of Spiders in Florida

Florida’s warm climate and high insect activity make it an ideal environment for many spider species. Most spiders are harmless and actually help reduce pest populations, but some can become a concern when they begin nesting indoors.

Here are the spiders you’re most likely to see in Florida homes and businesses:

American House Spider
(Parasteatoda tepidariorum) Often found in corners, garages, and storage areas. These spiders build webs to catch flying insects and are generally harmless.
Wolf Spider
(Hogna spp.) Large, fast-moving ground spiders. They don’t spin webs and prefer hiding in leaf litter, garages, and sheds. Can startle homeowners due to their size but rarely bite.
Golden Silk Orb-Weaver
(Trichonephila clavipes) Also called the banana spider, this large outdoor species is common in Florida. It builds big golden webs in gardens and trees and is generally harmless despite its size.
Cellar Spider / Daddy Longlegs
(Pholcus phalangioides) Thin, long-legged spiders found in basements, garages, and ceilings. Harmless and often eat other spiders.
Black Widow Spider
(Latrodectus mactans) Recognized by the red hourglass marking. Venomous and found in dark, undisturbed areas like sheds, garages, and woodpiles.
Brown Widow Spider
(Latrodectus geometricus) More common in Florida than the black widow. Identified by an orange hourglass. Usually found around patio furniture, outdoor containers, and mailboxes.

Life Cycle of Spiders

Understanding the spider life cycle helps explain why webs and activity can increase quickly.

Egg → Spiderling → Adult

Egg
Female spiders lay egg sacs containing dozens to hundreds of eggs. Warm climates like Florida help these eggs hatch quickly.
Spiderling
Newly hatched spiders disperse in search of food and shelter. Many stay close to webbing or nest sites.
Adult
Adult spiders hunt, build webs, and reproduce. Lifespans vary by species, but Florida’s climate allows many to stay active year-round.

Why It Matters

  • Some spiders in Florida are venomous
  • Web buildup can indicate larger insect problems
  • Indoor sightings often mean abundant food sources nearby
  • Certain species multiply quickly in warm, humid climates

Problems and Risks Caused by Spiders

Bites
Web Accumulation
Increased Insect Activity
Nuisance Issues

Common Signs of a Spider Problem

  • Webs in corners, ceiling edges, and light fixtures
  • Spiders appearing in bathrooms, garages, or storage rooms
  • Egg sacs attached to webs, furniture, or walls
  • Increased insect activity indoors
  • Spiders hiding in shoes, clothing piles, or boxes

If you’re finding spiders regularly inside, there may be underlying pest activity attracting them.

Where You’ll Find Them in Your Home or Business

Spiders prefer quiet, undisturbed places where insects are active

  • Garages and attics
  • Sheds, patios, and screened enclosures
  • Corners of rooms and ceilings
  • Behind furniture or appliances
  • Closets and storage areas
  • Outdoor landscaping, mulch beds, and wood piles
  • Commercial storage rooms and warehouse spaces

Widows prefer dark, sheltered areas like meter boxes, patio furniture, and sheds.

Why Spiders Thrive in Florida

Florida’s warm temperatures and high humidity allow spiders to stay active year-round. The abundance of insects provides constant food, while palm trees, mulch beds, and outdoor structures offer ideal shelter. Homes near water, vegetation, or dense neighborhoods often see increased spider activity because prey insects are plentiful.

Why You Need Professional Spider Control

DIY sprays often miss hidden webs, egg sacs, and nesting areas. Some spiders avoid treated surfaces completely. Professional spider control focuses on:

  • Removing webs and egg sacs
  • Identifying and treating insect sources that attract spiders
  • Targeting outdoor conducive areas
  • Using safe, precise treatments around entry points
  • Preventing venomous species from settling near the home
