Spiders are basically lazy landlords. They move in where the rent is free, meaning: bugs. If you have flies, ants, or moths, you’re essentially running a spider buffet. Step one: seal up cracks around windows and doors with caulk. Spiders can squeeze through a gap the width of a credit card—which is terrifyingly small.
Also, turn off your porch light at night. That glowing beacon calls every mosquito in the county, and spiders love a delivery service. Think of it as Uber Eats for arachnids.
