Grab a caulking gun and a flashlight, and get ready to be your own handyman. Check every single crack, crevice, and gap around windows, doors, baseboards, and pipes. Even a hole the size of a pencil tip is a five-star hotel entrance for a spider. Seal it up like you’re padding a baby’s nursery—no gap is too small.
Don’t forget the attic and basement. Those are spider central, usually because they’re dark, dusty, and full of clutter. Clutter is spider paradise. Boxes piled against walls create perfect little spider highways. So, vacuum and declutter like you’re expecting your mother-in-law to do a white-glove test.
