The answer to 'how to prevent spider' is to take proactive measures to make your home less attractive to spiders. This includes sealing cracks and crevices, removing clutter, and using natural repellents. Regular inspections and targeted treatments can also help control spider populations.
Start by sealing any cracks, crevices, or entry points around your home's exterior using caulk or weatherstripping. This will prevent spiders from getting inside. Remove any clutter, wood piles, or overgrown vegetation near the home, as these provide ideal hiding spots for spiders. You can also use natural repellents like peppermint oil, vinegar, or citrus around entryways to deter spiders.
