The simplest trick? Make your home feel less like a forest and more like a sterile showroom—at least from the outside. Spiders often hitch a ride indoors through cracks, gaps under doors, or tiny openings around windows.
Grab a tube of silicone caulk and go to town. Seal gaps around pipes, baseboards, and eaves. It’s a boring Saturday project, but it’s also the single most effective barrier you can build.
Another pro tip: trim back shrubs and bushes that touch your house. Spiders love using leaves as highways. If you can create a two-foot gap of gravel or mulch between your foundation and the garden, you’ve just built a spider moat. Very medieval, very effective.
