Keep spiders out by sealing entry points, reducing insects that feed them, removing webs and clutter and limiting outdoor lights that attract prey. Most house spiders are harmless, but widow spiders can be medically significant.

Why spiders move in
Spiders follow food. Lights attract insects, insects attract spiders and quiet corners in garages, sheds and eaves give them places to build webs. Reducing insects reduces spiders.
Prevention steps
- Seal gaps around doors, windows, pipes and vents.
- Use yellow or warm-toned bulbs outdoors and keep lights off when not needed.
- Vacuum webs and egg sacs regularly.
- Store boxes in sealed plastic bins, not cardboard.
- Keep firewood, debris and shrubs away from the foundation.
- Shake out gloves, shoes and outdoor cushions before use.

Spiders to take seriously
Southern black widows and brown widows occur in Florida and may nest in garages, meter boxes and outdoor furniture. Wear gloves when working in cluttered areas. Seek medical care for a suspected widow bite, especially for children and older adults.
Professional help
If spiders keep returning, treat the cause: other insects. A recurring residential pest control plan can reduce the prey and treat harborage areas. Our Fort Lauderdale exterminator services team can advise. Related pests are covered in common household pests in Fort Lauderdale.
