Spiders at home aren’t threats—they’re allies in pest control

Spiders indoors are common and generally harmless, often serving as natural pest controllers by eating insects like mosquitoes. Bites are rare, and many species avoid humans, so killing them can remove a valuable predator from your home. If you really can’t stand a spider, gently capture and release it outside, but otherwise adopting a live-and-let-live approach supports a healthier indoor ecosystem—evidenced by a survey of 50 North Carolina homes where every house had spiders.
