Steel wool’s a classic, but I’ve seen mice chew right through the cheap stuff—especially the finer grades. The coarser, heavy-duty kind (like Brillo pads without soap) seems to hold up better, but honestly, I always recommend combining it with caulk or expanding foam. That way, they can’t just yank it out. As for peppermint oil, I’ve tried it in rental units and it smells nice, but I wouldn’t trust it as a real solution. Mice in older homes are just too determined... they’ll ignore the spa vibes and go straight for the snacks.
Keeping The Critters Out: Weird But Effective Tricks?
You nailed it about the mice being determined—sometimes I think they’re smarter than half the folks I know. I’ve had my fair share of run-ins with them, especially after moving into a place with original 1940s hardwoods and all those “charming” gaps. Tried the peppermint oil thing too, and while it made the mudroom smell like a fancy tea shop, the mice just seemed to treat it like a scented welcome mat.
I totally agree that steel wool alone isn’t enough. My first attempt was with the cheap stuff, and I swear, those little guys must’ve thought I was leaving out a midnight snack. The combo trick—steel wool plus caulk—has been a game changer for me. It’s not glamorous, but nothing says “not welcome” like a solid wall of pokey metal and sticky foam.
But you know, I actually had some luck with copper mesh instead of steel wool. It’s pricier, but doesn’t rust and seems tougher for them to chew through. Looks tidier too, which matters if you’re dealing with visible spots in a finished space. If you want to get fancy, there are even products made just for this that blend in with trim or baseboards.
I still laugh thinking about the time my neighbor tried blasting classical music in her crawlspace after reading somewhere that it “confuses” rodents. Didn’t work—unless you count confusing her husband when he went down there to grab holiday decorations.
Anyway, you’re definitely on the right track. Old houses have their quirks, but with a little persistence (and maybe some trial and error), you can outsmart even the craftiest mouse.

Copper mesh is a solid call—I've used it on a few jobs where the client wanted something that wouldn’t rust or look rough around the edges. It’s definitely tougher for mice to chew through, though I’ve seen some determined ones still try their luck. Ever notice how they’ll find the tiniest gap you missed? One time, I thought I’d sealed everything, but turns out there was a gap behind an old radiator pipe. Took me three tries to finally block it off for good. Anyone else ever try using expanding foam with the mesh? Sometimes it works, sometimes they just tunnel right through if you’re not careful...

Copper mesh worked for me too, but I had mixed results with expanding foam. Mice just chewed right through the foam in my basement, even with mesh inside. Ended up using steel wool in a few spots—ugly, but it did the trick. Those little gaps behind appliances are the worst... always one more you missed.

Totally agree—those hidden gaps are like a mouse superhighway. Steel wool is effective, but yeah, not the prettiest solution. If you want something a bit less industrial-looking, I’ve had luck with silicone caulk mixed with fine steel wool. You can kind of “sandwich” the wool inside the caulk so it’s less visible, and it still blocks them out. Not perfect for every spot, but works well around pipes or tight corners.
One thing I’ve noticed: mice seem to avoid peppermint oil. I was skeptical, but after dabbing some on cotton balls and tucking them behind my fridge, I stopped seeing droppings in that area. Maybe it’s just coincidence, but it’s worth a shot if you’re looking for something less harsh than chemicals or traps.
It’s wild how determined those little guys are. Even after sealing what felt like every gap, I found one squeezing through a crack smaller than a dime. Makes you rethink what “sealed” really means...
