How To Deter Spiders From House

Last week, I walked into my kitchen, half-asleep, reaching for the coffee maker. My hand froze mid-air because, dangling right next to the mug, was a spider the size of a small car. Okay, maybe not a car, but big enough to make me yelp like a cartoon character. I spent ten minutes trying to catch it with a glass and a piece of mail, only to watch it scuttle behind the fridge. That’s when I decided: we needed boundaries.

Look, I don’t hate spiders. I respect their role in eating mosquitoes and flies. But I also respect my right to not have nightly staring contests with eight-legged roommates. So, let’s talk about how to gently, yet firmly, ask them to move out. It’s all about making your home feel less like a cozy bug buffet and more like a no-vacancy zone.

Start with the great seal-up

Spiders are tiny ninjas. They can squeeze through cracks you’d never even notice. Grab a tube of caulk and go full detective on your baseboards, windows, and door frames.

Pay special attention to gaps around pipes and wiring holes. If you can fit a credit card through it, a spider can definitely fit through it. I sealed a tiny gap behind my stove last fall, and the spider population dropped by half.

Don’t forget the light attraction trap

Here’s the thing: spiders don’t just show up because they like your décor. They show up because other bugs are there first. Outdoor lights act like a neon “All You Can Eat” sign for moths and gnats.

Switch your porch and garage lights to yellow “bug lights” or LEDs with a warmer color. It’s less attractive to flying insects, which means fewer snacks for spiders. Think of it as cutting off their food delivery service.

Peppermint: the friendly chemical warfare

Spiders absolutely hate the smell of peppermint. It’s like us walking into a room that smells like burning tires—we’d leave. Mix 15 drops of peppermint essential oil with water in a spray bottle.

Spray it along windowsills, door thresholds, and baseboards. Reapply every week because the scent fades. Pro tip: Don’t spray it on fabric or untreated wood unless you want your couch smelling like a candy cane factory.

The great declutter mission

Spiders are shy introverts who love cozy, dark hiding spots. Piles of old newspapers, cardboard boxes, and random shoes are basically luxury condos for them. Go through your junk drawer—yes, that one—and recycle anything you haven’t touched in six months.

Vacuum under the bed and behind furniture more often than you’d like. It breaks up their webs and removes egg sacs before they become a surprise baby shower. Trust me, you don’t want to find a hundred tiny spiders in your laundry basket.

Use the sticky tape trick

For high-traffic spider zones (corners of ceilings, behind the fridge), place sticky traps. They look a bit grim, I know, but they’re incredibly effective. You’ll be shocked at how many spiders you catch that were living rent-free in your living room.

Just check them weekly and replace when full. This isn’t about being cruel—it’s about making a clear statement that this house is not a spider resort. You can also tuck a few behind heavy furniture where you won’t see them.

Diatomaceous earth: the silent killer

This is a white powder that looks like flour but is actually crushed fossilized algae. To spiders and bugs, it’s like walking over broken glass—it dries them out. It’s safe for pets and humans, but deadly for insects.

Sprinkle a thin line along baseboards, under sinks, and behind appliances. Leave it for a few days, then vacuum it up. It works wonders and costs about five bucks. Just don’t inhale it; it’s not cocaine.

Outdoor landscaping matters more than you think

Bushes and shrubs touching your house are like spider highways. Trim back any branches that touch the siding or roof. Move mulch and firewood away from the foundation.

Spiders love hiding in damp, dark places like leaf piles and wood stacks. Keep a two-foot gap of bare soil or gravel around your house. It’s basically a moat they don’t want to cross.

A final word on the bathroom fan

I learned this the hard way: spiders can come in through exhaust vents. Check your bathroom and kitchen fan covers for gaps. You can buy a fine mesh screen to cover the outside vent, which keeps them out while still letting air flow.

And for the love of all that is holy, shake out your shoes before putting them on. I once had a spider nest in my sneaker, and I still shudder when I think about it. Inner peace is worth a few minutes of preventive paranoia.

At the end of the day, you won’t get rid of every spider. And honestly, you don’t want to—they’re part of the ecosystem. But with a little caulk, some peppermint, and a ruthless decluttering session, you can turn your home from a spider nightclub into a boring, spider-free library. And my kitchen? I sprayed everything with peppermint and sealed that crack. Last I checked, the only thing dangling near my coffee maker was my spoon. Victory.
