Why Spiders Start Showing Up More in Florida Homes in September
Seeing more webs in corners or long legs zipping across the floor this September? You’re not alone. Many homeowners notice the sudden change and wonder if it means an infestation.
September is spider season in Florida. During this time, common Florida spiders get more active and easier to spot.
Spiders come indoors for a few reasons. During mating season, males leave hiding spots to look for mates. Late-summer rains and high humidity also push pests like roaches, ants, and flies inside. Spiders follow this food, so your home becomes a prime hunting ground.
This guide explains why September is spider season in Florida, which species of spiders you might see, where they hide, when it’s a problem, and how to keep them out.
Key Takeaways:
- September is Florida’s spider season, so more spiders show up indoors during mating.
- Florida homeowners see several types of Spiders in September, including common house spiders, wolf spiders, and jumping spiders. Venomous species like the black widow and brown widow also live in Florida.
- Spiders come inside for food and shelter, hiding in attics, garages, crawlspaces, and wall gaps.
- Professional pest control treats spiders and their food sources to remove them and prevent future infestations.
Why September is spider season in Florida
In Florida, September brings more spider activity because it’s mating season. As they search for mates, you’ll notice them in new places.
Food draws them in, too. Roaches and other bugs slip inside for moisture and shelter, and spiders follow. They often settle in attics, garages, and storage areas.
In Miami, Fort Lauderdale, and West Palm Beach, this happens every year. If you see more spiders now than in June or July, you’re right; it’s spider season.
Types of spiders you might see indoors
Florida is home to many common spiders. Knowing what you’re seeing helps you choose the proper fix.
Common house spiders spin webs in corners and storage areas. They’re not dangerous, but their webs and egg sacs are a pain to clean.
Wolf spiders are large hunters that don’t spin webs. You may see them run across floors or pop up in garages and crawlspaces. Smaller jumping spiders stand out for their quick moves.
Florida is home to several venomous spiders. Black widows often hide in dark corners of sheds or garages, easy to spot by the red hourglass marking on their abdomen. Brown widows are less dangerous than southern black widows, and often nest around outdoor furniture, fences, and sheltered corners.
Brown recluse spiders are rare in Florida homes. If you do see one, look for a light brown body and a violin-shaped mark behind the head. Their bites are venomous and may need medical care.
Where spiders hide in your Florida home
Spiders rarely stay in the open. They look for quiet places to hide. Attics and basements are dark and undisturbed, so spiders can build webs, catch food, and reproduce.
Spiders also like hiding in garages. You will usually see wolf spiders and house spiders that follow insects indoors in this area. Crawlspaces and wall crevices also give them perfect places to stay hidden while they hunt.
If you find webs or egg sacs in several rooms, a small spider problem may be turning into an infestation.
When a spider problem becomes serious
Not every spider sighting means trouble. But if you notice more webs, more crawling activity, or repeated black widow or brown recluse sightings, it’s time to act.
Venomous spiders can cause painful bites. Spider bites are rare, but repeated sightings are risky.
Spiders often signal that other pests are present. To get rid of spiders, you also need to stop the insects they eat from entering your home.
How to keep spiders out of your Florida home
Start by sealing entry points. Check for small cracks around your windows, doors, and utility lines, then seal them. Even the smallest crack can serve as an entry point for spiders if left unchecked.
Keep your home clean. Vacuum webs and remove egg sacs. Clear clutter from garages, attics, and basements to minimize hiding spots.
DIY steps don’t always solve spider problems. Because spiders often follow other pests, professional help is usually best. A licensed pest control professional can identify the species, remove them safely, and prevent future infestations.
Choosing professional pest control for your Florida home
