Spiders have a strong sense of smell—and they’re picky. They hate peppermint, eucalyptus, tea tree, and citrus. Mix 10-15 drops of essential oil with water in a spray bottle, and mist corners, windowsills, and baseboards. Refresh it once a week, and you’ll create an invisible “no vacancy” sign.
Pro tip: Place dried cedar chips or chestnuts in closets and drawers. Not only do they smell great, but spiders also find the texture unpleasant to walk on—like crawling over a scratchy wool sweater.
