Let’s be honest: you can never 100% spider-proof a house. They’re tiny, they’re sneaky, and they’re incredibly determined. But if you seal cracks, remove clutter, use peppermint spray, and turn off outdoor lights, you’ll drop their population from “infestation” to “rare, startled guest.”
And when you do see that lone spider three months from now? Don’t panic. Just remind it who runs the place. You do. And you have mint.
