Metal conduit’s a solid call, especially if you’ve got stubborn rodents. I’ve had mixed luck with those spray foams—mice just chew right through unless there’s something tougher behind it. One trick I picked up is stuffing steel wool into gaps before sealing them up. Not perfect, but it slows them down. And yeah, skipping the fall check always seems harmless until you’re mopping up water at 3am... learned that one the hard way too.
Steel wool’s a classic, but I’ve actually run into some issues with it rusting over time, especially in damp areas around plumbing. That can end up staining or even corroding nearby pipes if you’re not careful. I get the appeal—rodents don’t like chewing through it—but I started switching to copper mesh for that reason. It won’t rust, and it’s just as tough for critters to get through.
If you’re sealing up gaps, I’d suggest a quick step-by-step:
1. Clean out the opening—old insulation, droppings, whatever’s in there.
2. Pack in copper mesh as tight as you can.
3. Use a high-quality sealant or mortar, depending on the size and location of the gap.
4. For bigger holes, I sometimes add a metal plate or hardware cloth behind the patch for extra peace of mind.
On the spray foam—totally agree, it’s not a standalone fix. I’ve seen mice tunnel right through that stuff like it’s nothing. It’s more of a draft blocker than a rodent barrier, in my experience.
And yeah, skipping the fall check is tempting, but I’ve learned to treat it like clockwork. I actually keep a checklist taped inside the utility closet: drain hose bibs, check for leaks, inspect insulation, and make sure all the crawlspace vents are closed up tight. It’s a pain, but it beats dealing with burst pipes or a surprise mouse nest in January.
One thing I’d add: if you’re dealing with recurring rodent issues, it might be worth looking at landscaping too. Overgrown shrubs or stacked firewood near the foundation can be an open invitation. I didn’t realize how much that mattered until I cleared out some ivy and suddenly stopped seeing droppings in the basement.
Anyway, just my two cents—sometimes the “old tricks” need a little tweaking to really hold up over time.

That checklist idea is gold—beats my usual “hope I remember before the first freeze” approach. Curious, have you ever had issues with critters getting *behind* the copper mesh? I’ve seen some determined squirrels in my day... Also, anyone tried stainless steel mesh instead of copper? Wondering if it’s worth the extra bucks or just overkill.
Honestly, I think copper mesh is a bit overrated for critter control. I’ve seen mice chew right through it if they’re motivated enough. Stainless steel’s tougher, but it’s pricier and not exactly eco-friendly to produce. I actually switched to a combo—recycled steel wool packed in tight, then a mesh cover. Squirrels haven’t gotten through yet, and it’s cheaper. Just gotta check it every season, though... nothing’s totally squirrel-proof.
I hear you on the copper mesh—my neighbor swore by it until a mouse basically laughed in his face and chewed right through. I tried the steel wool trick too, but man, that stuff rusts if you get any moisture near it. I ended up using hardware cloth (the metal grid stuff) and caulked the edges. Not pretty, but so far, no furry squatters. Honestly, I feel like every season brings a new rodent Houdini act...
