Why are spiders around my front door? A South Florida porch guide
Short answer: Most spiders on South Florida porches and lanais are there because of the insects they eat. Porch lights draw flying insects at night, and spiders build webs where the food is. Cutting down on outdoor lighting, sweeping webs regularly, trimming plants away from the house and treating the exterior for insects all help reduce spiders around your porch.
If you step outside in the morning and walk into a web on your front porch, you’re not alone. Homes across Palm Beach County, from Wellington to Delray Beach, see a lot of spider activity on porches, lanais, screen enclosures, eaves and garage doors. Here’s why it happens and what you can do about it.
Why spiders gather on porches
- Light attracts their food. Porch and garage lights draw moths, gnats and other flying insects at night. Spiders build webs near those lights.
- Shelter. Eaves, corners, railings and screen frames give spiders protected places to build.
- Plants close to the house. Shrubs and palms touching the house give spiders, and the insects they eat, easy access.
- Warm weather. South Florida’s climate means spiders are active much of the year.
Common spiders you may see
- Spiny orb weavers: small, colorful spiders with spiky shells, often in shrubs and along eaves
- Golden silk orb weavers (banana spiders): large spiders with big golden webs between trees and structures
- Other orb weavers that rebuild their webs at night
- House spiders in corners and under eaves
- Widow spiders: less common to see, but they can be found in sheltered, cluttered areas such as garages, under outdoor furniture and in utility boxes. Wear gloves when moving stored items.
Most of the spiders you see on a porch are a nuisance rather than a danger, but it’s best not to handle any spider. See our spiders page to learn more.
How to cut down on spiders and webs
- Change the lighting. Turn off porch lights when you don’t need them, or use yellow “bug” bulbs, which attract fewer insects.
- Sweep webs regularly. A long-handled brush or broom keeps webs from building up and removes egg sacs.
- Trim plants so they don’t touch the house, screens or roof.
- Reduce clutter on porches, lanais and in garages.
- Seal gaps around doors, windows and screens.
- Treat the insects. Fewer insects means fewer spiders. Exterior pest control that targets the insects around your home helps reduce spider activity too.
How Q&L can help
Our residential pest control service focuses on the exterior, including eaves, entry points and the foundation, where many spiders and the insects they feed on start. We inspect, treat the perimeter and knock down webs and nests, then treat inside only when it’s needed. We serve homes across Palm Beach County, including Jupiter, Palm Beach Gardens, Boca Raton and Lake Worth Beach.

Frequently asked questions
Are the spiders on my porch dangerous?
Most porch spiders are a nuisance, not a danger. Widow spiders are the main ones to be careful around. If you’re unsure what you have, don’t handle it and ask for an inspection.
Why do the webs come back overnight?
Orb weavers often rebuild their webs every night. Regular sweeping plus reducing the insects they feed on helps.
Do yellow porch lights really help?
Yellow bulbs attract fewer flying insects than standard white bulbs, which can mean fewer spiders building webs nearby.
Will pest control get rid of all spiders?
It can reduce them significantly, but in South Florida some spider activity outdoors is normal. Regular service and good habits keep it under control.
