How To Get Rid Of Wood Lice In House

So, you’ve got wood lice. Or as I like to call them, those tiny, startled-looking armored pill bugs you find in the bathroom at 2 AM.

First off, don’t panic. They’re not cockroaches, and they won’t eat your house or your clothes. They’re just nature’s little cleanup crew that took a wrong turn and ended up inside your sock drawer.

Let’s get rid of them. And trust me, it’s easier than explaining why you still sleep with a childhood teddy bear.

Step One: Stop Being Comfy for Wood Lice

Wood lice are basically tiny, damp-loving tourists. They need moisture like a potato needs a jacket—actually, they are basically potato bugs. So, start by hunting down moisture in your home.

Look under sinks, near leaky pipes, and around your washing machine. That damp spot behind the toilet? That’s a five-star hotel for wood lice.

Fix those drips. Wipe up standing water. Dry is the enemy of the wood louse. If you can make your home feel like Arizona in July, they’ll pack their little exoskeletons and leave.

Step Two: Declutter the Floor (Yes, That Means the Pile of Magazines)

Wood lice love hiding under things. Flipping over a leaf in the garden? Gnarly. Flipping over a damp cardboard box in your basement? That’s a wood louse rave.

So, pick up boxes, old newspapers, and that pile of laundry you swear you’ll fold tomorrow. Sweep under furniture. Vacuum baseboards like you’re hunting for lost coins.

Why? Because wood lice are shy. They don’t want to be seen. Take away their hideouts, and they’ll just give up. It’s the bug equivalent of canceling Netflix—they’ll wander off.

Step Three: Seal the Cracks (They’re Not Ninjas)

Wood lice don’t break through walls. They find gaps. Check around door sweeps, window frames, and gaps in the foundation. If you can poke a toothpick through it, a wood louse can squeeze its little armored butt through.

Use caulk or weather stripping. You don’t need a contractor—just a tube of sealant and a bad attitude toward bugs.

Also, check your air vents and dryer vents. I once found a wood louse queue forming outside a floor vent, like they were waiting for concert tickets.

Step Four: Bring in the Natural Cavalry

Before you reach for the chemical nukes, try gentler stuff. Diatomaceous earth is like glass shards for bugs—but only to bugs. It’s food-grade and harmless to you and your pets.

Sprinkle a fine line of it along baseboards, under sinks, and near doorways. When wood lice crawl over it, their waxy coating gets scratched up, and they dehydrate. It’s poetic, really.

Got a garden or balcony? Move firewood away from the house. Wood lice love love love living in wood piles. Think of it as evicting them before they throw a housewarming party in your living room.

Step Five: Use Sticky Traps (Because You’re Smarter Than a Pill Bug)

Those sticky glue traps for insects? Pop a few behind your fridge or washing machine. They’re like little tourists traps, but with no souvenirs.

Check them every week. You’ll probably catch a few—and maybe a spider or two who thought he was being sneaky. It’s not a bug genocide; it’s more like a gentle redirection.

And no, you don’t need to buy a fancy exterminator spray. Save your money for ice cream. Wood lice are pushovers.

A Few “Don’ts” to Keep You From Crying

Don’t leave wet towels on the floor after a shower. That’s basically booking a room for them on Expedia. “Includes complimentary mold dinner.”

Don’t bring potted plants inside without checking the soil. I once brought a fern inside and accidentally invited a wood louse family reunion. Learn from my shame.

Don’t ignore your basement or crawlspace. If it smells like mildew, wood lice are already planning a community garden down there.

How to Keep Them Out Long-Term

Here’s the secret: Wood lice aren’t trying to invade. They just want to survive. So make your home harder to survive in.

Keep humidity low—under 50% if you can. A dehumidifier is boring, but so is waking up to a wood louse on your toothbrush.

Also, clean your gutters. Seriously. Clogged gutters create overflow, which soaks your foundation, which makes your walls cozy. Wood lice are basically checking your home’s moisture rating on Yelp.

The Uplifting Conclusion (You’re Almost Done)

So, here’s the good news: You’ve got this. Wood lice are one of the easiest house pests to evict. They’re slow, transparent about their needs (moisture, darkness, and a sad cardboard box), and they don’t carry diseases.

In fact, scientists call them “decomposers.” That’s a fancy way of saying they’re the cleanup crew for nature’s messy parts. They’re not malicious—they’re just really bad at reading room signs.

So dry out your home. Seal the cracks. And if you find one wandering across your kitchen floor at midnight, just scoop it up, say “You’re cute, but you need to go,” and toss it outside. No drama. No screaming.

Remember: A house with no wood lice is a house with less moisture—and that also means less mold, fewer other bugs, and a happier you. So thank them for the reminder, then show them the door. You’re the landlord here.

And hey, if you still have one or two lingering? Just name them. Call them Gerald. Once you name a bug, you can’t kill it. And honestly? Gerald’s probably just looking for his keys. Let him out.
