Spiders are drawn to light because it attracts insects. Keep outdoor lights off at night, or swap them for yellow “bug lights.” Inside, turn off unnecessary lights after dusk. Less light = fewer bugs = fewer spiders. It’s basic spider math.
And please, for the love of cozy evenings, seal your window screens. Check for rips. Patch them with screen repair tape. One tear is all it takes for a spider to do a high-wire act into your living room.
Chemical Options: Last Resort Only
If natural methods fail, use spider-specific sprays with ingredients like deltamethrin or cyfluthrin. Spray along baseboards, cracks, and dark corners. But please read the label. Keep pets and kids away until dry. These are not candy. They are serious business. Use them like you’d use a fire extinguisher—only when you need it.
Another option: glue traps. Place them near walls and behind furniture. They catch spiders (and other pests) without poison. Check them weekly and dispose of them. It’s grim, but effective. Wear gloves.
