What Stops Spiders Coming Into House

Let’s be honest—spiders are the uninvited house guests who never bring wine and always leave a mess. You might be okay with them in the garden, but the moment one rappels down from your ceiling fan, it’s war. So, what actually stops these eight-legged critters from moving in? The answer is simpler than you think, and no, you don’t need to set your house on fire.

The Secret is in the Smell (or Lack Thereof)

Spiders don’t have noses like we do, but they hate strong, specific scents. Think of essential oils as your spider-repelling perfume. Peppermint oil is their kryptonite—one whiff and they’re packing their tiny bags.

Mix a few drops of peppermint oil with water in a spray bottle and spritz around windows and doorways. You’ll smell like a candy cane, and spiders will steer clear.

Eucalyptus, tea tree, and lavender work too, but nothing sends them running like peppermint. Just don’t spray it directly on them—that’s just mean, and they’ll hold a grudge.

Clean Like You Mean It (But Not Too Much)

Spiders are basically tiny, messy teenagers—they love clutter. Piles of clothes, dusty corners, and cardboard boxes are their favorite condos. If you vacuum and dust regularly, you’re essentially bulldozing their dream homes.

Focus on sweeping behind furniture and under beds. Spiders think those dark, forgotten spots are exclusive real estate—make them feel like the property value just tanked.

And here’s the kicker: if you remove their food source, they’ll starve out. That means fewer flies, mosquitoes, and ants. So, fix that leaky faucet, keep the fruit bowl covered, and you’ll naturally evict the spider buffet.

Seal the Cracks (Spider Ninjas Are Small)

Spiders can squeeze through gaps you can’t even see—they’re nature’s escape artists. Check your windows, doors, and baseboards for tiny cracks and seal them with caulk. It’s like putting a “No Vacancy” sign on your house.

Don’t forget the gaps under doors! A door sweep is cheap, easy to install, and makes your door a fortress. Spiders hate a good door sweep because it ruins their dramatic, skittering entrances.

Even the smallest hole around a pipe or vent is a welcome mat. Use steel wool to plug larger gaps—spiders can’t chew through metal, and it makes them feel very uncool.

Light Up the Night (Spiders Aren’t Party Animals)

Outdoor lights attract bugs, and bugs attract spiders. It’s a chain reaction of irritation. Swap your bright white bulbs for yellow “bug lights” or motion-sensor lights that only turn on when you’re grilling.

Spiders prefer the dark, shadowy vibe—they’re basically goth teenagers. If your porch is well-lit and bug-free, they’ll decide “this party is lame” and move to a darker house down the street.

Also, keep outdoor lights off near windows. A glowing window is a dinner bell for insects, and spiders love a dinner bell almost as much as they love your sofa.

Embrace the Lizard Brain (The Spider Natural Enemy)

Believe it or not, spiders are paranoid about getting eaten. One of their biggest fears is the common house gecko or—wait for it—a cat. My cat has personally evicted three spiders this week by simply staring at the wall like a fluffy, judgmental god.

If you have a dog or cat, their movement and scent alone often scare spiders away. They think, “Nope, that’s a predator with fur and teeth. I’m out.” So, let your pet be your tiny, furry spider bouncer.

No pets? No problem. You can sprinkle diatomaceous earth (a fine, powdery dust) around baseboards. It’s harmless to you but feels like walking on broken glass to spiders. They’ll leave a one-star review on Yelp and never return.

The Zen Approach: Plant a Spider-Repelling Garden

Plants like lavender, mint, and rosemary aren’t just pretty—they’re spider repellents with benefits. Plant them near your windows or keep pots indoors. Plus, they smell way better than chemical spray.

Bonus: rosemary is delicious on roasted potatoes. So you can eat spider repellent for dinner. That’s what I call multitasking.

Spiders also hate citrus. Toss lemon peels from your morning tea into corners or near vents. They’ll think your house is a giant lemon, and since spiders aren’t fans of sour things, they’ll scram.

The Truth About Spider Webs (They’re Not Welcome Mats)

Don’t leave spider webs up as “decor.” Spiders actually reuse their webs and think, “Oh, the previous tenant left a nice starter home for me!” So, grab a broom and swipe those webs down. It’s like evicting a squatter before they even unpack.

Wipe down corners with a vinegar-water mix. Vinegar disrupts the pheromone trails they leave for other spiders. It’s basically a “House is Closed” sign in spider language.

And if you do see a spider in your house, don’t scream. Use a cup and a piece of paper to gently relocate it outside. You’ll feel like a heroic wildlife rescuer, and the spider will have to find a new place to haunt.

Final uplifting thought: Spiders are actually roommates with benefits—they eat flies, mosquitoes, and other bugs you definitely don’t want around. But if you really can’t stand them, remember this: your home is your kingdom. A little peppermint, a tidy corner, and a sealed crack can turn your house into a spider-free sanctuary. And if one still sneaks in? Just name it Gary, give it a tiny hat, and let it guard your kitchen from fruit flies. You’ve got this, savvy homeowner. Now go mist some peppermint and reclaim your castle.
