Fewer spiders starts with fewer bugs.

Spiders are predators, so the presence of other insects like flies, ants, or cockroaches attracts them. Even a small pest population gives them a reason to come hunt. Some, like the wolf spider, actively hunt instead of spinning webs, and a home with plenty of hiding places and prey makes an ideal hunting ground for them to settle in.

Spiders prefer dark, undisturbed corners, so spots behind cabinets, under the bed, or behind large furniture that isn't moved or cleaned often become prime web and nest sites. Spiders aren't drawn to light themselves, but their prey is, so indoor and outdoor lights pull in flying insects, which in turn attracts spiders looking for an easy meal.

During cooler months or sudden weather changes, spiders seek shelter indoors for warmth and protection, so you may notice more of them as the seasons shift, especially in autumn. Certain species are also drawn to moisture, which makes humid areas like bathrooms, basements, and kitchens appealing, particularly where there are leaks or condensation.

For the occasional spider, yes. Knock down webs, vacuum regularly, declutter, and seal cracks around doors and windows. The most important step is removing their food, since spiders won't stay where there's nothing to hunt. If you keep seeing them, it usually means there's an insect problem underneath that needs to be addressed too.

Call a pro if spiders keep returning, if you're seeing them throughout the home, or if you spot a species you're concerned about. A professional treats the spiders and the insects feeding them in one coordinated effort, clears webs and harborage, and helps seal the entry points so they don't simply move back in.
