How Can You Get Rid Of Woodlice

Okay, let’s be real for a second. You’re finding little grey armored tanks scurrying around your skirting boards, right? Woodlice. The pill bugs. The roly-polies that look like they’re wearing a miniature suit of medieval armor. Ugh. Don’t panic. I’ve been there, and we’re going to sort this out over a hot drink.

First off, let’s get one thing straight. Woodlice aren’t actually bugs in the true sense. They’re crustaceans. Crustaceans! Like tiny, land-based shrimp. Weird, right? They breathe through gills, which means they need damp places to survive. That’s your secret weapon right there.

Why Are They Even Here?

Think of your home as a five-star hotel for a woodlouse. A damp, dark, rotting-leaf kind of hotel. Are you leaving wet towels on the floor? Got a leaky pipe under the sink? Maybe some damp cardboard boxes in the garage? Bingo. They’re not there for the decor; they’re there for the moisture buffet.

They eat dead plant matter, mold, and mildew. So if they’re partying in your house, you’ve basically rolled out the red carpet for a fungus festival. Let’s cancel that event, shall we?

Step One: The Drying-Out Offensive

This is the most important step, and it’s almost too easy. Dry everything out. Grab a dehumidifier if you have one. Run the bathroom fan after a shower until the mirror is clear. Fix that leaky faucet you’ve been ignoring. Yes, that one. Woodlice hate dry air more than I hate soggy cereal. Hate it.

Move any potted plants away from the walls. Check your crawl space or basement. If it feels like a rainforest in there, you need a moisture barrier or better ventilation. You’re basically evicting them by taking away their swimming pool.

Step Two: Block the Borders

You need to become a tiny door inspector. Grab a tube of caulk or some weatherstripping. Seal up cracks in the foundation, gaps around windows, and the spaces where pipes enter the wall. Woodlice are small, but they’re not magic. They can’t pass through solid silicone.

Check your door sweeps. If you can slide a piece of paper under your exterior door, a woodlouse can waltz right in. Block it. They’re not paying rent, so they don’t get a key.

Step Three: The Clean Sweep

Get rid of their food source. Clear away dead leaves, grass clippings, and mulch from the foundation of your house. Create a gravel or dry strip around the perimeter. It’s like putting a mini desert moat around your castle.

Inside your home, stop leaving piles of damp newspaper or cardboard. Don’t store firewood indoors. Woodlice see that and think, “Oh, a beautiful, damp apartment complex!” Nope. Toss that stuff or move it to a dry, sealed bin.

Step Four: The Natural Eviction Notice

Okay, so you’ve dried things out and sealed the cracks. But what if a few stubborn squatters remain? Don’t reach for harsh chemicals yet. Try a little diatomaceous earth (DE). It’s a white powder made from fossilized algae. To a woodlouse, it’s like walking through a field of glass shards. It dries them out. Game over. Just dust it in thin layers near baseboards and cracks.

Another trick? A simple trap. Roll up a damp newspaper or an old potato slice and leave it on the floor overnight. In the morning, you’ll find a woodlouse party inside. Just scoop it up and toss them outside. Bye, Felicia.

A Quick Note on “The Infestation”

Are you seeing hundreds? Like, a scuttling carpet of them? That’s a red flag. A few woodlice is a minor nuisance. A ton of them means you have a serious moisture problem, possibly a hidden leak or rotting wood behind a wall. That’s a job for a professional. Call a pest control company or a plumber. Don’t be a hero.

The Bottom Line (Let’s Be Honest)

You’re never going to make your house a 100% woodlouse-free fortress. They live outside. They exist. That’s fine. The goal is to make your home uninviting. Like a hotel with no beds and bad reviews.

Just remember the golden rule: Dry, clean, and sealed. Do those three things, and those little armored pigs will look for a nicer place to crash. Like your neighbor’s compost pile. Oops, sorry, Pam. You’ve got this.

Your To-Do List (Pinky Promise)

Go check your bathroom vent. Right now. Is it dusty? Clean it. Remove dead leaves from the side of your house. Pick up that damp cardboard box. You don’t need to wage war. You just need to be a boring, dry host. And if a woodlouse still shows up? Smile, say “not today,” and sweep it outside. Coffee’s on me.
