Spiders are creatures of the dark. They hate bright, open spaces. If you leave a porch light on all night, you’re basically throwing a rave for moths, which then attract spiders. Irony: your security light is a spider’s bat signal.
Switch to yellow or sodium-vapor bulbs for outdoor lights. They’re less attractive to insects, which means fewer spider snacks. Inside, keep curtains open during the day. Sunlight is natural spider repellent, and it’s free. My favorite price.

Don’t forget the basement and attic
This is where spiders throw their secret parties. Basements are damp, dark, and full of forgotten junk—spider heaven. Get a dehumidifier if you can. Spiders hate dry air almost as much as they hate peppermint.
In the attic, seal any gaps around vents and pipes. Yeah, I know, attics are creepy. Bring a flashlight and a brave face. A few minutes of courage can save you months of web-cleaning.
