I know, I know—your first instinct is to squash or spray. But here’s the ironic twist: killing a spider inside your house is like hiring a bouncer and then firing him on the first night. You kill one, and a dozen more are just waiting to move in. The real trick is prevention, not revenge.
Think of your home as a fortress. You wouldn’t leave the drawbridge down, right? Exactly. Spiders come in because they find food (other bugs) and shelter (you). Cut off their supply chain, and they’ll leave on their own—or never even bother to knock.
